Informal emails are far more likely to get opened than marketing/sales ones. Propeller works tightly with gmail and helps me be personal to my whole list, plus stay in touch actively -- even though I have set it all up in advance. Great customer service too!

Ability to onboard new users and get them up is super quick. The user interface is very clean and compliments my team's sales efforts with Gmail efficiently.

The overall look is good. Colour scheme is good.
