Stable Infrastructure and Higher Reply Rates with Maildoso **Rating:** 5.0/5.0 stars **Reviewed by:** Patrick B. | CEO & President, Airlines/Aviation, Mid-Market (51-1000 emp.) **Reviewed Date:** May 27, 2026 **What do you like best about maildoso?** We switched from Inboxkit to Maildoso after another agency recommended it to us. During the first month, after warmup, our reply rates were around 1.5x-2x higher than what we were normally seeing before. What surprised me most is the stability after that initial period. At one point some mailboxes burned, so we paused campaigns for about 2 weeks. After restarting, performance actually improved instead of getting worse. Since then, the infrastructure has been running very consistently for us without needing constant maintenance or rebuilding inboxes every other week. **What do you dislike about maildoso?** The beginning was a little stressful because a few mailboxes burned during the first month, and we weren’t sure if we would have to repeat the whole setup process again. The dashboard could also be a bit clearer in some sections. **What problems is maildoso solving and how is that benefiting you?** Before this, managing outreach infrastructure felt like a nonstop cycle of creating inboxes, warming them up, replacing them, and setting everything up again. Maildoso reduced a lot of that manual maintenance for our team. At this point, we barely even check the dashboard anymore because things have been running pretty steadily for the last couple months. ### 2. Maildoso Made Outbound Campaigns and Inbox Management Easy **Rating:** 5.0/5.0 stars **Reviewed by:** Dhaval P. | Founder and CEO, Animation, Small-Business (50 or fewer emp.) **Reviewed Date:** May 20, 2026 **What do you like best about maildoso?** We started using Maildoso a few months ago for outbound campaigns and it has made inbox management easier for our team. I like that we can keep multiple sending accounts in one place without spending too much time setting everything up. The onboarding process was simpler than expected and we were able to start campaigns fairly quickly. **What do you dislike about maildoso?** The dashboard can feel slightly cluttered after adding more inboxes, especially when switching between accounts. Support has been decent overall, but there were a few moments where responses took longer than expected. **What problems is maildoso solving and how is that benefiting you?** It helps us manage outreach infrastructure without relying on a fully manual process. Before this, keeping track of inboxes and domain settings across different tools was more time consuming. With Maildoso things feel more centralized and easier to maintain week to week. ### 3. Maildoso Made Scaling to 300 SMTP Inboxes Easy with Big Cost and Time Savings **Rating:** 5.0/5.0 stars **Reviewed by:** Bob P. | Commercial Innovation Program Operations Leader, Pharmaceuticals, Enterprise (> 1000 emp.) **Reviewed Date:** May 15, 2026 **What do you like best about maildoso?** We’ve scaled up to roughly 300 SMTP inboxes using Maildoso and the cost difference compared to our previous setup became noticeable pretty quickly. We also integrated their API into part of our internal workflow so mailbox creation and basic monitoring happen automatically now instead of someone doing it manually every week. For teams handling larger outbound volume, that time savings adds up fast. **What do you dislike about maildoso?** Domain pricing is reasonable overall, but at our scale even small differences add up over time. I wouldn’t complain if domain costs were slightly lower. **What problems is maildoso solving and how is that benefiting you?** Infrastructure cost and operational overhead mainly. Before switching, maintaining large numbers of inboxes across different providers was getting expensive and messy. Moving over reduced our cost per lead quite a bit and simplified management for the team. ### 4. Effortless Email Management with Maildoso **Rating:** 5.0/5.0 stars **Reviewed by:** Jacob B. | Senior Solutions Consultant, Program Development, Mid-Market (51-1000 emp.) **Reviewed Date:** March 15, 2026 **What do you like best about maildoso?** For managing sending infrastructure without having to manually handle every technical detail, I find Maildoso to be helpful. The platform ensures that our team maintains consistent communication workflows by keeping mailboxes and domains organized. I also valued the simple onboarding procedure, which included clear instructions for setting up a mailbox and a domain connection, making it simple to get started without significant technical challenges. By offering monitoring and management tools that support consistent email delivery, Maildoso makes it easier to maintain a positive sender reputation. I'm very likely to tell a friend or coworker about Maildoso. **What do you dislike about maildoso?** Teams that frequently review performance data would benefit from more reporting flexibility and exportable analytics. **What problems is maildoso solving and how is that benefiting you?** I monitor sender reputation and maintain dependable email delivery by using Maildoso to handle outbound communication. It makes infrastructure management easier, enabling my team to maintain consistent workflows and keep domains and mailboxes organized without having to manually handle all technical details. ### 5. Stability and Efficiency Restored Our Email Campaign Performance **Rating:** 5.0/5.0 stars **Reviewed by:** Maddison M. | Marketing & ESG Coordinator , Transportation/Trucking/Railroad, Mid-Market (51-1000 emp.) **Reviewed Date:** May 28, 2026 **What do you like best about maildoso?** I appreciate Maildoso's overall stability of the infrastructure which has made our campaigns run consistently over time. We no longer worry about the system randomly breaking and having to rebuild everything. The onboarding flow feels smoother, and their support for Google Workspace and the API has made it easier for our team to manage campaigns without dealing with technical issues. The platform felt more stable compared to our previous experience. They also added new features like monthly plans and better integrations, which helped us manage outreach at scale. Our reply rates have improved, been better at around 5% lately, and I don’t constantly worry about the system randomly breaking anymore. **What do you dislike about maildoso?** The experience is definitely better now compared to 2025, but I still think communication during issues could improve a little more. During the earlier blacklist period there was a lot of uncertainty on our side. I think faster updates during incidents would help a lot, even if there isn't a full solution yet. During the blacklist period last year (2025), the hardest part for us was not really knowing how long things would take or what the next steps were. More proactive communication inside the dashboard or through email/slack would probably make situations like that feel less stressful for customers managing active campaigns. **What problems is maildoso solving and how is that benefiting you?** Maildoso has stabilized our email infrastructure, reducing technical disruptions and making campaign management smoother. Our reply rates have improved, and we spend less time on technical fixes, allowing focus on performance improvements. ### 6. Streamlined Outreach with Time-Saving Automation **Rating:** 5.0/5.0 stars **Reviewed by:** Tetsu A. | Vice President, Japan Partner Sales / Business Development/ Marketing, Information Technology and Services, Enterprise (> 1000 emp.) **Reviewed Date:** May 20, 2026 **What do you like best about maildoso?** I appreciate how Maildoso streamlines our client outreach campaigns by handling sending inboxes and domains for cold email, so we don't need someone constantly checking technical stuff. It made things more predictable for us, reducing the amount of troubleshooting we have to do weekly. I really like that it saves us time because once everything is running, we don’t have to babysit every inbox. Adding new accounts for another campaign is easier now. The process of managing at scale is faster, making it easier for our team to focus more on outreach performance and client work without spending too much time on infrastructure maintenance. The initial setup was easier than we expected, with straightforward steps that didn't require a long onboarding process. **What do you dislike about maildoso?** The interface could be smoother in some areas. Sometimes finding certain settings takes longer than it should. Support is okay, but not always super fast. **What problems is maildoso solving and how is that benefiting you?** I use maildoso for client outreach, reducing random deliverability problems, and cutting down weekly troubleshooting.

Once everything is connected, I don't have to keep fixing things every time I want to start a new campaign. I appreciate having multiple inboxes ready to use because it helps spread out sending instead of relying on just one account. It makes day-to-day outreach less stressful. Scaling is smoother since I don't have to spend time creating and configuring each inbox individually. It saves time and keeps things organized when running outreach. The initial setup was pretty straightforward, with clear steps that didn’t take much time to figure out. **What do you dislike about maildoso?** Support could be a bit faster sometimes, especially when we’re setting things up or something isn’t clear. It’s not a constant issue, but when you’re trying to launch a campaign it can slow things down a bit. Also the dashboard could feel a little smoother when switching between multiple inboxes, it gets slightly repetitive when you’re managing a lot at once. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to save time on email outreach by easily managing multiple inboxes and domains. It simplifies setup, reduces errors, speeds up launching campaigns, and keeps our operations organized, lessening stress and pressure on single inboxes. ### 8. Effortlessly Manages Email Campaigns **Rating:** 5.0/5.0 stars **Reviewed by:** Fadi G. | Marketing Director, Market Research, Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2026 **What do you like best about maildoso?** I like using Maildoso for managing cold email campaigns because it simplifies handling a large number of inboxes and dealing with replies without the hassle of manual setup. The automated DNS settings are great since our domains last 2 or 3 times longer, which addresses domains burnout. I have 80 active mailboxes that send about 17-20 emails each, totaling around 30,000 emails a month, and our placement rates are strong, close to 95% on testing. It's also nice that they push updates often, showing that they are actively improving things instead of just leaving it as is. Setting up Maildoso was pretty smooth compared to our previous more manual setup. Overall, I'm extremely likely to recommend Maildoso. **What do you dislike about maildoso?** I had a hiccup with a non US credit card not going through.

Effortless Cold Outreach with Reliable Deliverability **Rating:** 5.0/5.0 stars **Reviewed by:** Michael U. | Founder & CEO, Program Development, Small-Business (50 or fewer emp.) **Reviewed Date:** April 21, 2026 **What do you like best about maildoso?** I find the global customer tracking really helpful because it prevents hitting spam filters even when including links in the first email, which is great for scheduling demo calls early. Our reply rate is around 3-5% in a competitive B2B SaaS niche, and the API integration with Instantly was seamless, connecting mailboxes with just one click. I also appreciate the savings on domain registration, which is just $12 for a .com, and there’s no need to stress over manually writing MX and SPF records. The initial setup was pretty smooth as well. **What do you dislike about maildoso?** There were a couple of delays with activating new workspace accounts. The site said 2 hours but it actually took until the end of the day. Their response rate needs to be improved. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso for cold outreach, sending campaigns with links without hurting deliverability. It saves on domain registration costs and simplifies email setup, and global tracking improves deliverability, helping us book demos early. ### 10. Effortless Mailbox Scaling with Automated DNS **Rating:** 5.0/5.0 stars **Reviewed by:** Nazhin B. | Design Lead, Program Development, Mid-Market (51-1000 emp.) **Reviewed Date:** April 21, 2026 **What do you like best about maildoso?** I appreciate Maildoso for solving our clustering issues, where each mailbox is isolated, preventing all accounts from being affected if one gets banned. The transition of moving 120 mailboxes was smooth, with no breakage. What stands out to me is not having to manually set up DNS for every domain, as it's automated, saving a lot of time. This automation allows us to spin up new domains faster. Additionally, the pricing is noticeably cheaper than our previous provider, and the initial setup was straightforward. **What do you dislike about maildoso?** Support can sometimes make you nervous. I messaged the chat on the site and waited about four hours for a reply which was annoying. When something feels urgent, waiting a few hours can be a bit stressful, especially if campaigns are running. Even a quick acknowledgement would help so you know someone is on it. **What problems is maildoso solving and how is that benefiting you?** Maildoso isolates each mailbox to prevent cluster bans, automates DNS setup saving time, and offers cheaper pricing than our previous provider. ### 11. Game-Changer for Cold Emailing with High Deliverability **Rating:** 5.0/5.0 stars **Reviewed by:** Christy D. | President, Airlines/Aviation, Small-Business (50 or fewer emp.) **Reviewed Date:** April 13, 2026 **What do you like best about maildoso?** I appreciate maildoso for its Global Custom Domain Tracking feature, which is a complete game changer. It allows me to add links like Calendly or Loom to the first email without worrying about landing in the spam folder, providing more confidence when sending campaigns. The IP reputation is very high quality compared to what you get elsewhere, effectively stopping the 'spam folder' trap. The initial setup was pretty well, and overall, I'm extremely likely to recommend maildoso to a friend or colleague. **What do you dislike about maildoso?** I wish there was an audit log to see what my other team members changed. Maybe just more visibility into how the tracking is performing would be nice, like simple stats. **What problems is maildoso solving and how is that benefiting you?** I use maildoso to send campaigns with links like Calendly or Loom without worrying about spam. It stops the 'spam folder' trap with high IP reputation, and GCDT boosts confidence by allowing links in emails without hurting deliverability. ### 12.

It's very convenient to buy domains directly in the dashboard, and the initial setup was straightforward, which made the transition smooth. **What do you dislike about maildoso?** Some of my domains got blacklisted after the first campaign, but they replaced them for me with new ones. I think the main thing would be better prevention or early warnings, like some kind of alert if a domain is at risk before it actually gets blacklisted. **What problems is maildoso solving and how is that benefiting you?** Maildoso automates our email outreach, eliminates the need for a dedicated tech person, and significantly improves email deliverability (90-95%). It's convenient to buy domains directly from the dashboard. ### 13.

It allowed us to double our outbound volume this quarter without doubling our infrastructure spend, solving the scaling costs issue. We are sending nearly 45k emails a month across 150 boxes, and the uptime is solid without any mass suspensions. The cost is predictable, averaging about $2 per mailbox, which makes planning a lot easier as scaling up doesn't come with surprises. The initial setup was pretty straightforward. **What do you dislike about maildoso?** There's no mobile app. I'd like to be able to check domain health while I'm away from my computer. It's mostly about quick access. Sometimes you just want to check the domain or mailbox health when you're not at your desk. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to double our outbound email volume without increasing our infrastructure costs. The uptime is solid, and costs per mailbox are predictable, making scaling easier without financial surprises. ### 15.

I like that the isolation feature works well, as each domain operates independently, which helps with our outreach efforts. The fact that we achieved decent results with hitting Outlook is reassuring. I also found the knowledge base to be actually useful, especially during the setup process. The initial setup was pretty smooth, and that's definitely a plus for me. **What do you dislike about maildoso?** I had an issue connecting via Bluemail. I eventually found the answer in the docs myself. **What problems is maildoso solving and how is that benefiting you?** I use maildoso for cold outreach, which helps diversify risk by not being dependent on just one provider like Google.

Cost-Effective Scaling with Effortless Integration **Rating:** 5.0/5.0 stars **Reviewed by:** Michael B. | Founder/CEO, Program Development, Mid-Market (51-1000 emp.) **Reviewed Date:** March 25, 2026 **What do you like best about maildoso?** I really appreciate that Maildoso is built for scale. We run about 400 mailboxes through it, and the cost savings we get compared to Google Workspace or Microsoft 365 are huge. The one-click integration with our sequencer made getting started very easy. The SMTP setup makes it easy to handle large volumes without things breaking, so I don't have to worry too much about managing individual mailboxes. **What do you dislike about maildoso?** There's no built-in warm-up tool anymore, so you have to rely on an external service for that. It's not a huge issue, but it does add one more step to manage. It would be better if they added a simple built-in warm-up feature again, even something basic. Right now, switching between tools makes the process a bit fragmented. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to lower costs and scale email outreach. Managing 400 mailboxes, I send 50k-70k emails monthly without budget increases. The SMTP setup simplifies large volumes, with one-click integration easing the startup process. ### 19. Effortless Email Scaling, Exceptional ROI with Maildoso **Rating:** 5.0/5.0 stars **Reviewed by:** Igor R. | CTO, Program Development, Mid-Market (51-1000 emp.) **Reviewed Date:** March 23, 2026 **What do you like best about maildoso?** I appreciate Maildoso's pricing, which keeps our costs around $2 to $2.50 per mailbox while including both SMTP and Google Workspace. This is a very good deal from my experience. I also like the automated DNS setup (SPF/DKIM), which saves a lot of back and forth with the technical team. Another aspect I like is the simplified setup, which makes sending at scale much more reliable. The initial setup was pretty straightforward thanks to the automated DNS configuration. **What do you dislike about maildoso?** The UI is very basic. It's not 'pretty' by modern SaaS standards and sometimes navigating feels a bit tricky. It will be pretty good if all this could be improved. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to scale our email outreach. Managing over 120 mailboxes manually was a nightmare, but now we send 35,000 emails monthly and book 100+ calls without stressing about infrastructure. It simplifies setup, automates DNS, and offers competitive pricing for SMTP and Google Workspace. ### 20.

The IP rotation Maildoso uses for SMTP effectively keeps our accounts out of the spam folder, stabilizing our sending reputation. **What do you dislike about maildoso?** The onboarding documentation could be clearer. If you aren't already familiar with how cold email infrastructure works, you might find the initial setup a bit confusing. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso for cold email outreach at scale, managing multiple mailboxes to keep stable deliverability and avoid blacklist issues. Its self-healing and IP rotation features maintain our sending reputation, making sure emails don't fall into spam and improving reply rates. ### 21. Effortless Scaling with Maildoso **Rating:** 5.0/5.0 stars **Reviewed by:** Will B. | Co-Founder and CEO, Transportation/Trucking/Railroad, Small-Business (50 or fewer emp.) **Reviewed Date:** March 20, 2026 **What do you like best about maildoso?** I use Maildoso to efficiently build and manage our mailboxes and domains for outreach. It solves the issue of burning through domains by capping at 15 emails per day per box, which has stabilized our deliverability. I'm impressed with how fast it sets up domains, mailboxes, and DNS configurations, making them ready to use quickly. The ease of scaling is Maildoso's biggest draw; scaling from 75 to 300 boxes without a dip in deliverability was seamless. I find managing the domain-to-mailbox ratio simple with Maildoso, and creating new domains and mailboxes in minutes without needing technical expertise is great. I enjoy the IP rotation and inbox reputation monitoring features that keep our outreach in people's inboxes rather than spam. The setup was really straightforward, getting our domains and mailboxes live and ready in just a few minutes. **What do you dislike about maildoso?** The dashboard analytics are a bit thin and I think it could be more detailed.

Boosted Email Deliverability and ROI **Rating:** 5.0/5.0 stars **Reviewed by:** Michelle M. | Fractional Controller, Financial Services, Small-Business (50 or fewer emp.) **Reviewed Date:** March 20, 2026 **What do you like best about maildoso?** I use Maildoso for managing outbound email setups across multiple domains and mailboxes, mainly for cold outreach campaigns. What I like most about Maildoso is its reliability and pricing. The SMTP + Google Workspace combo (15 + 15) provides a solid setup at a very low cost per mailbox, making it unbeatable for the price. This combination is really effective because using SMTP alongside Google Workspace helps spread sending across different systems. It offers flexibility in how we set things up while maintaining low costs. Overall, it's a good balance between performance and affordability. Additionally, the initial setup of domains and mailboxes with Maildoso was pretty easy and didn't take long. **What do you dislike about maildoso?** The main thing for me is the limited TLD options in the app. It would be better to have more domain choices available directly. Having more TLD options available directly in the platform would make scaling easier without relying on external providers. It would also be helpful if domain purchasing and setup were a bit more streamlined inside the app so everything can be managed in one place. **What problems is maildoso solving and how is that benefiting you?** I use maildoso for managing outbound email setups across multiple domains and mailboxes. It solves the problem of emails going to spam, improving deliverability significantly and increasing our reply rate from 0.5% to 2.5%. ### 23. Reliable Deliverability for German B2C Markets **Rating:** 4.0/5.0 stars **Reviewed by:** Weymouth G. | Small-Business (50 or fewer emp.) **Reviewed Date:** March 16, 2026 **What do you like best about maildoso?** I mainly use Maildoso for scaling and stabilizing our B2C email outreach in Germany. It lets me warm up new domains and email accounts automatically, so I can safely increase sending volume without getting blocked or blacklisted. I also like how it manages multiple inboxes in one place and keeps our main company domain completely separate from outreach, so our core business communication is never affected. Maildoso helps me significantly with email deliverability—something that’s absolutely critical for B2C in Germany—and it takes away all the stress around it. I appreciate how it handles domain warming and inbox reputation so smoothly that I can focus on creating campaigns instead of fixing technical issues. It’s reliable and just works quietly in the background without complicated setups or constant troubleshooting. Another big plus is how well it handles German email providers like GMX, Web.de, and Outlook.de, which improves our open rates and response rates. **What do you dislike about maildoso?** The user interface feels a bit basic compared to more modern tools—it's functional but not as polished or visually clear as some German-focused email tools, which makes it take a little time to get used to. Some automation features are also limited. You can't set up super complex workflows directly inside the platform; for more advanced B2C sequences, I still have to connect it with other tools. It's great for deliverability, but not as strong for full campaign automation. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to fix spam folder issues, protect our main company domain, manage multiple inboxes in one place, and ensure stable B2C email outreach in strict markets like Germany. It automatically warms up domains and improves deliverability, saving us hours and keeping communications safe. ### 24.

So far, it's been great! **Rating:** 4.0/5.0 stars **Reviewed by:** Brendan G. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** April 23, 2025 **What do you like best about maildoso?** What I like best about Maildoso is how transparent and granular it is when it comes to deliverability reporting. Unlike tools like Instantly, which give you a single overall score that doesn’t tell the full story, Maildoso breaks things down by domain—so you can actually see how your emails are performing across Gmail and Outlook. That means if your emails are hitting spam in Outlook but doing fine in Gmail, you’ll know right away and can adjust accordingly. It takes the guesswork out of deliverability and helps you make smarter, faster decisions. **What do you dislike about maildoso?** What I dislike about Maildoso is that even with all the preventative measures we’ve put in place, our inboxes still seem to get affected pretty quickly. So I’m still unsure if deliverability is actually the issue—or if it’s more about the niche we’re currently targeting, which is on the riskier side when it comes to health-related content. That said, we’ll be shifting toward less sensitive niches moving forward, so we’ll see how it goes. I’m hoping that’ll give us a clearer read on whether it’s a deliverability tool issue or just the nature of the campaigns we’ve been running. **What problems is maildoso solving and how is that benefiting you?** I don’t have much to compare it to since it’s the only email infrastructure tool I’ve used so far, but it’s definitely made it easier to monitor performance and spot red flags before they become real problems. - [View maildoso pricing details and edition comparison](https://www.g2.com/products/maildoso/reviews?query=AI+agent&via=toolify§ion=pricing&secure%5Bexpires_at%5D=2026-05-30+16%3A36%3A03+-0500&secure%5Bsession_id%5D=7ad3d0f7-ccec-40bc-9aff-4c972e194605&secure%5Btoken%5D=859675f1f2ba14f668a7556871ef13e2c2f179e3051e6ceab12331f44a3b4eb8&format=llm_user) ## maildoso Integrations - [Corporate Finance Institute](https://www.g2.com/products/corporate-finance-institute/reviews) - [Instantly](https://www.g2.com/products/instantly/reviews) - [lemlist](https://www.g2.com/products/lemlist/reviews) - [Microsoft Outlook](https://www.g2.com/products/microsoft-outlook/reviews) - [Smartlead](https://www.g2.com/products/smartlead/reviews) ## maildoso Features **Email Marketing** - Email and Mobile Preview - Manage Email Lists - High-Volume Sending - Building and Personalizing Emails - Sending Outbound Emails - Manage Email Deliverability - Automated Email Responses - Multi-user Account - Surveys **Reporting & Analytics** - A/B Testing - Basic Reporting **Generative AI** - AI Text Generation - AI Text Summarization **Agentic AI - Email Marketing** - Autonomous Task Execution - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Cross-system Integration **Integration** - Data Import & Export Tools - Integration APIs - Breadth of Partner Applications - CRM Integration - Social Media Integration - E-Commerce Integration ## Top maildoso Alternatives - [Instantly](https://www.g2.com/products/instantly/reviews) - 4.8/5.0 (4,088 reviews) - [Mailforge](https://www.g2.com/products/salesforge-mailforge/reviews) - 4.7/5.0 (85 reviews) - [Smartlead](https://www.g2.com/products/smartlead/reviews) - 4.5/5.0 (327 reviews)
