Email Drip Campaign

Hi There!

I am trying to figure out how to create a multi-month drip campaign. It would look something like this:

#1 I sent a form to a client, who then fills out the form, including with their email address
#2 One month later they automatically receive an email from me
#3 Two months later they receive another email
#4 Two months later they receive another email
#4 Three months later they receive one final email

I am trying to figure out the easiest way to do this. Curious what people are using that seems to be cleanest? Airtable automations? Zapier? Something else? I am NOT super technical, but LOVE have made Airtable work for me in incredible ways so far!!
