Your audience
Put the signup form on your own website
Copy one iframe snippet and collect emails on Squarespace, Wix, WordPress, or plain HTML — straight into your Sendit list.
1. Copy the snippet
On the Audience page, find “Embed on your site” and hit Copy code. You get a single <iframe> snippet — no script tags, no account keys, nothing to configure.
2. Paste it anywhere
Squarespace and Wix: add a Code/Embed block and paste. WordPress: a Custom HTML block. Plain site: paste it into the page. The form is themed to match your Sendit pages and sizes itself to its container.
3. Same list, same rules
Signups from your website flow into the same combined mailing list, with the same double opt-in confirmation. There's a Preview link next to the snippet if you want to see the form before placing it.
