3.) Set up Activepieces, a Zapier alternative ($3.80/month on Pikapods) 4.) Sign up for a Ko-Fi account (5% service fee) and connect it to Stripe (2.7% + 5¢ fee) and/or PayPal (2.89% + 49¢ fee) 5.) Connect Listmonk and Ko-Fi together using a webhook on ActivePieces and a short script.

6.) Set up the script to add the user to a list or a segment of an existing list using Listmonk’s API. 7.) Set it so that you send a transactional email to that user. 8.) In the email, include a link to a page on your website 9.) On that page, load a cookie.

10.) On your site, create a CSS type that hides content unless a certain class is loaded in the body tag. 11.) Create a small script that adds that script to the body tag only if it detects that cookie. (You could probably harden it if you really wanted, but it doesn’t have to be that strong.)

12.) Create a login page that checks against your list—again, using a webhook that triggers an ActivePieces script that, if the email matches, sends a message to the user with a link to the page with the cookie.

13.) And if the person ends their subscription, set up an exit script in Activepieces, with a goodbye email and a flow that moves them back to the free list. Same format as the hello email. Works essentially the same way. No overthinking. That’s it.
