## How the Zap works.

1.  **Connect both accounts.** In Zapier, connect Squarespace and Letterhead. You only do this once.
2.  **Start in Squarespace.** Choose a new Squarespace form submission as the trigger.
3.  **Finish in Letterhead.** Choose the Add or Update Contact action. Each time the Zap runs, Zapier adds the person to your Letterhead audience, or updates them if they're already there.

Zapier lists the exact triggers Squarespace offers. You'll need a Zapier account, and Zapier's plans and limits apply.

## Questions about Squarespace.

How do I connect Squarespace to Letterhead?

Through Zapier. Connect your Squarespace and Letterhead accounts in Zapier, start the Zap with a new Squarespace form submission in Squarespace, and finish it with Letterhead's Add or Update Contact action.

Is there a built-in Squarespace integration?

No. Squarespace connects to Letterhead through Zapier, so you'll need a Zapier account, and Zapier's own plans and limits apply.

What can Letterhead do in a Zap?

Letterhead's Zapier app can add or update a contact, add a contact to a tag, remove a contact from a tag, and add content to your curations library. Zaps start in the other app and end in Letterhead.
