When your Instant AI email includes a discount, we automatically add the Gmail Promotions “deal” markup in the HTML. Gmail can then show a promo chip like “Free shipping” and “Expires today” in the Promotions tab preview. The code itself won’t be exposed in the preview.
No setup in Instant is required. The only step is getting your sending domain approved by Google.

Thank you! - Wait for approval
Google manages this process end to end. Approval timelines vary. If you need an update, reply to p-Promo-Outreach@google.com.
After approval
You’re done. Instant AI already includes the required markup whenever a discount is present, so your existing emails will start showing eligible promo chips in Gmail automatically.
How to verify
-
Send a test email with a discount to a Gmail address.
-
Check the Promotions tab preview. You should see a chip such as “Free shipping” and an expiry label when relevant.
-
If you don’t see it, give it time and test a few more sends. Gmail decides when to surface chips.
What Instant AI annotates
-
Deal label: e.g., “Free shipping” or “10% off”
-
Expiry: shown when an expiry exists on the discount
-
Code visibility: hidden in the preview. The code stays inside the email body.
FAQs
Do I need to add or edit HTML?
No. Instant AI adds the markup automatically when a discount is present.
Does this work outside Gmail?
Annotations are a Gmail Promotions feature. Other inboxes ignore the extra markup without any downside.
Will this reveal the coupon code in the preview?
No. Gmail shows the deal and expiry, not the code.
What if I use static Shopify codes or other code formats?
If a discount exists in the email, Instant AI will annotate it. Expiry is shown when we detect one.
Does this affect deliverability?
Annotations don’t change deliverability. Normal authentication (SPF/DKIM/DMARC) still applies.
Why don’t I see the chip every time?
Gmail decides when to show annotations based on its own logic. Allowlisting is required, but chips may still not appear 100% of the time.
Troubleshooting checklist
-
You emailed p-Promo-Outreach@google.com and included all sending domains/subdomains.
-
You’re testing an email that actually contains a discount.
-
The discount has a valid future expiry if you expect “Expires…” to appear.
-
You tested to a real Gmail inbox and checked the Promotions tab.
-
Your domain is properly authenticated for email (SPF/DKIM/DMARC).
