GMass vs Mailmeteor and Streak: which Gmail follow-up tool should you use?
Job: Automate email follow-ups from Gmail. Our pick is GMass, the free option is Auto Follow Up It!, and here is whether to keep the tool you already use.
Our pick
GMass
Chosen for: Automatic follow-up sequences are included in the cheapest plan, inside Gmail.
Price: Standard is $29.95/mo billed monthly, or $249/year.
Time to start: ~20 min (install, connect Gmail, write a 2-step sequence) (our estimate)
Why not Streak? It's a full CRM in Gmail. Paid plans start at $49/user/mo billed annually ($59 monthly).
Caution: Only email people who know you. Automated follow-ups to cold lists are the fastest way to land in spam.
