I have a handful of subscriber lists to marketing and general communications in [Sender.net](http://Sender.net)

I used to have a Mailchimp account but they reduced the free tier to only 500 contacts.

I would like to know how to sync to Sender, and preferably from also, so I can properly track who opts out of communications.

Any tips aside from “let the AI agent handle it”?

No but seriously, what kind of tips are you looking for?

Custom integrations have the ability to make Custom Actions, so you’ll want to create a send action.

Actions are run on a loop per entity you select and run it on. So if you’re sending to 5000 people, and you select them all then press “Send with Sender” it will call Sender 5000 times.

I have never used sender, but they probably want a single call with the list of contact…? in which case you’d want to make an action which takes a list as input, and set up the button on a “List”, and it then uses a formula to join all the emails in the list, and sends that to Sender.

So there’s a few different approached you can go about it, but in general you’d want to use the Custom Integration framework Fibery has.
