B2B Contact Databases Software

While the lead generation is fast, the data accuracy can be a major headache. I’ve run into too many "verified" emails that ended up bouncing, which puts my domain reputation at risk. The user interface also feels a bit cluttered and overwhelming, making the learning curve steeper than it needs to be. Review collected by and hosted on G2.com.

One thing I dislike is that when I import data from Sales Navigator, Apollo sometimes changes a person’s job title or company name. That makes the data less accurate, and I end up having to correct it manually.

Also, the LinkedIn extension doesn’t allow bulk uploads of a large number of leads at once. You can only save 25 people at a time, which feels slow when I’m trying to build a bigger list.

Another frustrating issue is that when I add multiple people from the same company, the tool asks me to choose the domain every single time. It would be much better if it automatically remembered the domain for that company. Review collected by and hosted on G2.com.

The biggest problem Apollo.io solved for me was a fragmented sales process that relied on too many different tools. A feature I really love is being able to save prospect lists from Sales Navigator directly into Apollo, which has made my prospecting much faster. Instead of bouncing between multiple platforms for data and emails, I can now handle everything in one place and keep my workflow simple and consistent. As a result, I’ve saved about 60% of my manual research time, since the data is already integrated and easy to organize and manage. Overall, it’s made my job as a business development professional more productive and more successful. Review collected by and hosted on G2.com.

I don’t dislike anything about the tool. My main suggestion is to keep expanding the data coverage for Latin America. We also use it for searches in Europe, Asia, the Middle East, and the US, and in those regions I’ve found it to be very robust.

It would be great to improve the presence of, and access to, information for countries in Latin America. Also, some of the contact information isn’t updated—there are cases where contacts no longer work at their companies or don’t hold those positions anymore. That said, I understand this isn’t easy to keep current in a world where professional mobility moves so fast.

Overall, I love ZoomInfo and have already recommended it to former colleagues and family. Review collected by and hosted on G2.com.

ZoomInfo Sales helps me find prospects and decision-makers worldwide, so I can reach people I can’t easily access directly or through other tools. It also strengthens our email campaigns and has helped us generate good deals. Review collected by and hosted on G2.com.

I don’t have any specific pain points. If you’re using the built-in CRM, it would be helpful to have a few additional sections in the pipeline to better refine and track interactions. Review collected by and hosted on G2.com.

We had no real understanding of who was accessing our site, when they were visiting, or whether any of our external marketing was working. This has actively allowed us to see who is on our site, when they visit, and where they’re coming from, which helps us understand whether mail campaigns or third-party directory advertising is working by showing where each individual accessed the site from. Review collected by and hosted on G2.com.

One thing I’d like to see improved is how connected the ABM and Sales Intelligence (SI) sides are. They use the same underlying data, so a lot of the info overlaps, but in practice they don’t always feel fully integrated. For example, ABM segments can now be seen in SI, which is great, but not the other way around. I’d love it if sales could create lists in SI and push them into ABM so we could use them directly in campaigns. While I understand that the platform serves two different purposes, it would be really beneficial if we could look at the same data and segments/lists as both sales and marketing. A tighter connection here would also help with full sales and marketing alignment, making it easier for both teams to work from the same playbook.

There are also some feature gaps between the two. In SI, you can’t see advertising activity, while that info is available in ABM at the account level. Filtering in SI is also less intuitive: things like complex OR logic aren’t as easy to set up compared to ABM. These small differences make it feel a little disconnected when you’re trying to use both together.

A better connection/alignment between ABM and SI would make the platform even stronger. Review collected by and hosted on G2.com.

Before 6sense, we struggled with limited insights into the buyer journey, disconnected datasets, and complexity that made scaling difficult. We had little visibility into account behavior, which led to misaligned outreach, inefficient prospecting, and generic campaigns.

Since implementing 6sense, GTM now operate from a shared, prioritized view of accounts, eliminating silos and guesswork. We can validate historical activity and personalize outreach, ensuring timely and relevant engagement. The platform makes building segments much more efficient, and predictive models automatically classify accounts, reducing the need for manual work. Real-time intent and account stage data help us prioritize outreach and streamline campaign management, while all the platform integrations enable highly personalized, persona- and vertical-based campaigns at scale.

Overall, 6sense has transformed our processes from manual and fragmented to data-driven, aligned, and efficient, improving targeting, engagement, and impact across the buyer journey. Review collected by and hosted on G2.com.

I feel like lists take a long time to download compared to other tools like Seamless. Also, the number of credits feels much smaller than what I’m used to with tools like Seamless, so I usually end up using Seamless more and saving my Wiza credits for specific lists.

It helps me find leads to start email campaigns, funnels, and marketing strategies with just one click, without spending a lot of time building lists of people who fit specific criteria. Review collected by and hosted on G2.com.

Their support is the worst I’ve ever dealt with, and the people I spoke to were the least helpful. First, they unethically refused to reverse a payment that was deducted because my account wasn’t cancelled on their end. I did everything correctly and contacted them as soon as possible, with proof. Then they told me I would only get my money back if I took down my review. Review collected by and hosted on G2.com.

I used it to search for leads, but it didn’t work in my case. It didn’t find what I was looking for, at least not the way it’s marketed. Review collected by and hosted on G2.com.

The main drawback is the accuracy of employee data. It’s not uncommon to find prospects listed who have left their companies. This can lead to wasted time and effort when reaching out, so as other have already mentiones before improving the frequency of updates would significantly enhance the platform’s reliability- or act on flagged numbers. Additionally, some email addresses appear to be generated intuitively based on patterns rather than verified, which can result in bounced emails. Phone numbers also often lead to gatekeepers instead of direct lines to the prospect, which adds another layer of difficulty for outreach. Review collected by and hosted on G2.com.

Cognism helps solve one of the biggest challenges in sales development: finding accurate and relevant prospect data. Instead of spending hours researching companies and contacts across multiple sources, I can access detailed information in one place Review collected by and hosted on G2.com.

Slightly deeper contact coverage might be beneficial for certain specialised geographical sectors. Review collected by and hosted on G2.com.

Importing into our CRM was simple because the download procedure was fast and the data columns were arranged neatly. It offers an affordable alternative to larger subscription platforms for accessing targeted real estate agent email lists. Review collected by and hosted on G2.com.

Its not much to dislike though, but, Campaign Slow Ramp is on by default and throttled my sends to about a third of what I configured. Took real troubleshooting to find it. The campaign limits and account limits also reset on different clocks, which is not explained anywhere obvious. Logic is fine once you get it, but the onboarding assumes you will just figure it out.

I run outbound for a boutique audiobook production company, and this tool instantly handles multi-account sending and warmup without requiring any technical setup. It keeps deliverability steady and sequences well organized, which lets me focus on the actual copy and targeting instead of worrying about the infrastructure.

In case of the high price category, we would anticipate a more client-responsive and proactive customer success team. Although on gets responsive help on the support tickets, the response may also be transactional. A special account manager who offers the best-practice advice would take the service to a new level of a great tool to a must-have partnership. Review collected by and hosted on G2.com.

It addresses the serious issue of the quality and relevance of leads to our niche. Our filters in the form of industry, revenue and company size filters help us to make sure that we are only going into prospects that are in line with our high-value service offering. This has greatly enhanced the efficiency to our sales team and has played a key role in getting a number of flagships in the luxury automotive and fashion industry.

I find that the retrieval of financial data and financial risk are aspects that could be improved with Delpha. Review collected by and hosted on G2.com.

I use Delpha to enrich contacts and companies and handle duplicates, including the enrichment of Siret numbers in France and VAT numbers in Europe, thus simplifying onboarding through an intuitive interface and native integration with Salesforce. Review collected by and hosted on G2.com.

I need to find new customers as I am in New Biz Dev.

LinkedIn Sales navigator helps me get to my target audience efficiently. Review collected by and hosted on G2.com.

While Skrapp.io is a useful tool overall, there are a few downsides that can be frustrating. One of the main issues is that the email database, while generally accurate, can still return outdated or incorrect emails at times, especially for smaller companies or less active profiles.

The credit system can also feel limiting. Credits get used up quickly, particularly when you're doing bulk searches or verifications, which means you may need to upgrade sooner than expected. For smaller users or startups, this can make it feel a bit expensive for the value provided.

Another drawback is that the platform can occasionally be slow when extracting large lists, and the LinkedIn integration doesn’t always capture every available contact, requiring some manual effort to fill in the gaps.

Lastly, while the interface is simple, some advanced filtering and segmentation features are missing compared to more robust competitors, which can limit deeper prospecting strategies.

Overall, Skrapp.io works well for basic use, but it may fall short if you need more advanced functionality or higher scalability. Review collected by and hosted on G2.com.

Skrapp.io solves one of the biggest challenges in B2B outreach, finding accurate contact information for the right people quickly. Instead of spending hours manually searching for emails or guessing formats, it allows me to instantly find verified email addresses using just a name, company, or LinkedIn profile.

Another major problem it addresses is low-quality or invalid data. Sending emails to incorrect addresses leads to high bounce rates and wasted effort. Skrapp.io’s built-in email verification helps ensure that the contacts I reach out to are valid, which improves deliverability and campaign performance.

It also solves the issue of time-consuming lead generation. With features like LinkedIn integration and bulk email extraction, I can build targeted prospect lists in minutes instead of hours. This makes the entire outreach process much more efficient and scalable.

Because of these solutions, the benefits for me are clear:

I save a significant amount of time on prospecting

My outreach campaigns have fewer bounces and better response rates

I can focus more on closing deals rather than searching for contacts

It helps me scale outreach efforts without needing a large team

Overall, Skrapp.io turns a slow, manual process into a fast and data-driven workflow, which directly improves productivity and results. Review collected by and hosted on G2.com.

Just wish I had it earlier! I will say that because Collective[i] can feel “too good to be true,” it takes our sellers some time to fully trust the AI. But once they see the accuracy of the insights and how much time it saves them, it’s all systems go. The initial skepticism quickly turns into full adoption once they realize how much more productive they can be. Review collected by and hosted on G2.com.

Before Collective[i], our sales team struggled with inconsistent data, inaccurate forecasting, and inefficiencies in sales execution. Now, we have:

- Real-time, AI-driven pipeline insights that proactively highlight risks and opportunities.

- No more manual CRM updates, freeing our sellers to focus on selling.

- Better forecasting accuracy, leading to smarter decision-making.

- AI-driven deal coaching, improving win rates and seller productivity.

Overall, Collective[i] has been a game-changer for our revenue organization. If you're serious about leveraging AI to drive sales performance, eliminate manual work, and improve forecasting accuracy, Collective[i] is a must-have. Review collected by and hosted on G2.com.

Nothing major to dislike. The platform works well overall, but expanding the database further for international founders and adding more filters for niche targeting would make it even better. Apart from that, the data accuracy and ease of use have been very good. Review collected by and hosted on G2.com.

None**What problems is Mr. E by EasyLeadz solving and how is that benefiting you?**

Mr. E by EasyLeadz solves the problem of finding accurate contact details of founders, CXOs, and decision-makers without spending hours on manual research. It provides direct phone numbers and emails with one click, helping users instantly connect with the right people instead of going through gatekeepers or outdated data.

For me, it helped in reaching top founders and business owners directly. This significantly reduced the time spent on prospecting and improved outreach efficiency. Instead of relying on LinkedIn messages or generic emails, I was able to contact decision-makers directly, which accelerated conversations, partnerships, and business opportunities. Review collected by and hosted on G2.com.

One thing we observed is that sync timing and field mapping occasionally need monitoring, especially wen dealing with large or fast moving datasets. There were moments where updates didn`t reflect instantly or required a quick check to confirm everything aligned correctly. It didn`t break workflows, bt it did mean we stayed attentive to data consistency when campaigns were scaling, Review collected by and hosted on G2.com.

SalesTaget.ai helps reduce the disconnect between prospecting activity and CRM visibility. Instead of outreach data living in Isolation, it becomes part of the broader sales record. That makes reporting cleaner, follow ups easier to manage and collaboration between teams more structured. It essentially turns outbound from a siloed function into something that fits naturally into the wider revenue workflow. Review collected by and hosted on G2.com.

Very disappointed with this B2B lead generation company. They promised high-quality, verified leads but delivered completely garbage data. Most of the contacts had incorrect phone numbers, invalid email addresses, or were irrelevant to our target industry. We wasted both time and money trying to clean and verify the data ourselves. When we raised the issue, their support team was unresponsive and avoided taking responsibility. Review collected by and hosted on G2.com.

They aren't capable to solve anything Review collected by and hosted on G2.com.

I don’t like that Nooks doesn’t load all contacts from a company during a one-off call. It only pulls in a few, which limits my options when I’m searching for and calling prospects in Nooks using the One-off feature. Review collected by and hosted on G2.com.

Nooks helps me deal with the constant changes and switching of numbers during calls. It automatically rotates numbers based on the prospect’s area code and on how many calls I’ve already made from a given number within a particular time period. This feature is really beneficial and saves me a lot of time. The availability of live battlecards and transcripts is also helpful, and the fact that I can easily access HubSpot and Apollo lists directly from Nooks is another big time-saver.

I can't afford the subscription to keep using Success.ai service although I need it the most. Maybe let's see in the future if Success.ai can give more discount! Review collected by and hosted on G2.com.

Success.ai gives the solution for the issue of time-consuming lead generation and manual cold email outreach. Instead of using multiple tools to find leads, verify emails, send campaigns, and track replies, the platform combines everything in one place. It helps me simplify the entire outreach process and makes it easier to reach potential clients at scale.

This is beneficial because I can save a lot of time, reduce manual work, and make outreach more organized and efficient. The automation, AI email writing, and analytics features can help my new businesses focus more on building relationships and closing deals instead of managing boring tasks.
