Help Center/Email and newsletters

Can my website use my Substack instead of a Podspun list?

Yes. In your website's editor, open Config and then Email List. Under Signups Go To, choose Substack and paste your Substack address (for example https://yourname.substack.com, or the custom domain your Substack is on). Every email signup on that website, the footer signup block and the signup pop-up, then shows Substack's own subscribe box, and the addresses people enter go to your Substack list. It is one or the other: with Substack chosen, no Podspun list is used for that website. Choose Podspun to go back to your own list.

When you build a site from a link and your old website linked to a Substack, the address is filled in for you.
