I needed to integrate my Gravity Forms with MailPoet. I installed the free plugin, "Add-on for Gravity Forms for Mail Poet3." But it did not work.

However, I had a copy of Bit Integrations Pro. It says it integrates MailPoet with Gravity. It was simple to set up but still wouldn't work. Bit Integrations Pro support responded quickly, asked for the credentials and checked my site, turned off the Add-on for Gravity Forms/MailPoet (which no longer works or is supported) and... it worked perfectly.

Solved a MAJOR problem!! Their list of integrations was small when I actually picked this up--but they have already added more (and some I care about). Great investment--much cheaper than Zapier and SUPER easy to use.
