Great service! I have used Streak to automate a one-time mailing list for an outreach program. The service integrated decently well into my Gmail environment and only took a little bit of tinkering to figure out. The free version caps you at 50 emails per day and limits your ability to automate follow-ups. One feature to suggest: allow users more ease of editing their mailing list once uploaded. Additionally, sometimes the correct pane needed to finalize email sending does not appear, and the Streak menu must be reopened. So navigability could be improved, but overall, great extension!

Nice & useful

One of the best CRM extensions online. I have been using it for over 9 years and it works great. Thanks
