This is just a MASSIVE list of many of the more popular CRMs, Mailing lists and Data Bases you can connect to with Bonjoro, direct or via Zapier.
This is always being added to so check: https://www.bonjoro.com/automation#/
Currently as of 11th May 2019:
Infusionsoft / Keap
Free through Zapier
Note many of these will be built direct into Bonjoro over time, however these are all available today on Zapier, and you will always be able to build more custom & multi-step workflows on Zapier integrations.
For help on setting up Zapier integrations, see our 4 part series starting here
If you want us to make any of these direct, please reach out and let the team know, we build integrations on a customer voting basis:)
