Hi @james,
I’m switching from Mailchimp to a new mailing subscriber called SendFox.
Currently, everybody booking a class gets added to the mailing list via the integration.
I understand you wouldn’t want to work on integration for every mailing applications out there, but what about Zapier? SendFox is integrated with Zapier and so I could do it that way.
Thanks to advise!
Kindest regard, Virginie
