I'm not looking for a fancy full-fledge email service provider.
What I'm looking for is a way to capture email address on our blog at draftly.so and have them stored in a google spreadsheet. I can then zap them to whatever service I prefer.
Don’t really have a real answer but if "zap them to whatever service I prefer" means "use zapier" couldn’t you just create a HTML Input Field with a button next to it and when the user clicks the button the value from the input field is sent to a Zapier Webhook? That way you’d directly have them in Zapier. Not sure if that helps, depends a bit on your programming knowledge but if you have further questions let me know.
