Customer.io vs Gmail: Which is best for you?

Very configurable, good tracking of comms, including Human vs Machine Opened statuses on emails.

Lack of options for email design in comparison to other platforms.

I like the search feature the most as well as the folders for organizing mail etc. profile pictures and the chat is very convenient for finding the person you’re sending mail to.

one main thing is the memory which gets used in your google account if you are backing up your photos in google photos app , it will eat up your gmail memory and you might stop receiving emails if you dont upgrade.
