I love how easy it is to manipulate the data in my contacts to filter through and find someone I haven’t been in touch with for a while and reach out!

The automatic email sync from multiple accounts makes it easy to keep new contacts in your database. They have lots of integrations too.

I can't decide between the grading system (gamifys my contacts and grades me based on how good I've been about staying in touch with people) or the ScaleMail feature. Scale mail let's me send a "mass email" but I can add a custom touch to each and ever single one. So let's say I added 50 people I met at a networking event... I can email them all the same email, each personalize with their name, and then add in a custom message at the top. And I can track if they open/click on a link. And I can schedule it to go out whenever I want so they don't know I stayed up until 3am working. It's amazing.
