I currently use Square Appointments for my clients to book services.
I also am using Integromat to automate the pull from Square and then push those clients into a Moosend email list where an email is sent out.
It’s pretty flaky and I would like to bring Newsletter in house and send all my welcome emails and drip campaigns in house.
The issue is getting the Square appointments data into Newsletter in order to send out the emails. I don’t see anything built in that would work how I want it to but would it be possible to dev something like a WP plugin that would do this?
