I've got Bluetick working in coordination with Gmail / Streak so as prospects move through my pipeline they get added to the appropriate email sequence and that's it. The emails go out without the hassle I had before of tracking who was sent what when and who did (or didn't) respond. Everything's in my Gmail mailbox but actually processed, tracked and organized.
So far, Bluetick has saved me hours and hours of work but, more importantly has helped me write to the right people at the right time and not write to the wrong people at the wrong time.
I can see multiple uses for Bluetick and plan to switch a number of other sequences (such as onboarding emails) over as I feel much more in control of what's going on compared to an ESP.
