Where forms live

Wherever your customers already are.

  • Its own page

    A hosted signup page with a link to share on social media, receipts or a QR code at your counter.

  • On your website

    Copy the embed code into any page of your site.

  • Shopify, Wix and Webflow

    Connect your shop or site so customers who opt in join your list in 404 Emails.

What a form asks

As little as possible.

An email address, and a first and last name if you want them. Your heading, description, colours and the thank-you message are up to you.

Clear permission

You write the marketing permission text people agree to. Each signup keeps a record of when, where and what they saw.

Double opt-in, if you want it

People confirm with a click in an email before they're added - proof the address is real and theirs.

Sorted on arrival

New subscribers can be put into a group or tagged automatically, and can start an automation such as a welcome email.

Questions about forms

Can I match the form to my website?
Yes: set the form's background, text and button colours.
Do I need a developer?
No for the hosted page and the embed code - copy, paste, done. The Wix connection uses a small piece of code we give you.
Is double opt-in required?
No, it's your choice per form. It's a good idea if your list matters to you or your industry expects proof of consent.
