Instant AI makes it easy to start collecting subscribers and welcoming them with on-brand emails without needing any setup or design work. Here’s how it works.
How to Use Instant Sign-Up Forms
Instant Sign-Up Forms are branded pop-up forms that appear on your Shopify storefront to capture new visitors and grow your email list. They’re generated automatically by Instant AI, styled to match your store’s brand, and powered by Predictive Opt-In so they appear at the best time to boost sign-ups.
Why Use Instant Sign-Up Forms?
-
Predictive timing – forms resurface automatically when a visitor is most engaged and likely to subscribe.
-
Higher conversions – median submit rates for standard pop-ups are around 2.3%. Predictive Opt-In averages 7%, with some brands seeing 20%+.
-
Instant integration – captured subscribers can trigger your Welcome Flow instantly.
-
Fully branded – matches your store’s logo, imagery, and tone of voice.
How to Access the Editor
You can open the Sign-Up Form Editor in two ways:
-
From Flows – scroll to the bottom of the Flows page and click Explore under “Smart Signup Pop-Ups”.
-
From Settings – go to Settings → Sign-Up Forms.
Editing Your Form
Inside the editor, you can:
-
Choose Layout – Portrait, Landscape, or Full Size.
-
Logo – show, hide, or replace your store logo.
-
Image – replace with a custom image (recommended for visual appeal).
-
Background – optional background image or colour. Without this, the panel will have empty space, so we recommend adding one.
You can only have one pop-up design active at a time.
Linking Coupons to Your Form
If you have an active coupon in Instant Coupons, we’ll automatically:
-
Include it in your Welcome Flow.
-
Write your pop-up copy to reference the offer.
-
Apply the same coupon across other Instant AI flows (Abandonment, etc.).
If you have no coupon set up, the form will still run but won’t reference any discounts.
Publishing Your Form
-
Click Save Changes to apply edits.
-
Once saved, changes are auto-published to your site.
-
If you click Unpublish, the form will move to draft and stop showing on your store.
Enabling Your Welcome Flow
To start sending welcome emails to new sign-ups:
-
Go to AI Flows → Welcome Flow.
-
Toggle the flow ON.
How it works:
-
Sends one email immediately after sign-up.
-
Includes your brand tone of voice, any store-wide promotions, top products, and your default Instant coupon (if set).
-
Only triggers from Instant Sign-Up Forms (other forms won’t start this flow).
Tip: You must have Sign-Up Forms enabled for the Welcome Flow to capture new subscribers.
