I like how Mixmax allows us to schedule prospect outreach at scale, with customized sequences for different personas. I appreciate the multi-step sequences, which can be batch uploaded and run in the background so it clears up time in my day to focus on other activities. Additionally, Mixmax has Smart Send functionality to send emails when the prospect is most likely to engage with it. It does a good job of being extremely customizable, including features to auto remove contacts from sequences that are active with another rep. Overall, it's pretty easy and intuitive to use once you get the hang of it.

it tells me when clisnt has opened and read emails it is great

Without Mixmax I wouldn't be able to tell which pitches are getting attention. It doesn't just tell you when someone opens your email, but also when they click on different things in your signature or email. I have tried other tools, and Mixmax is by far my favorite. I love the Mixmax Reminded folder it creates inside my Gmail, too, so if I get distracted I can go back and follow up to the pitches that I need to. One more thing is that it alerts you when someone opened you email 3 times so you can follow up - one of my favorite features!!
