Your results will appear here with source links. Check brand and date details against the original.

03 / Email that converts

Give every email
a clear next step.

Choose up to four references for Local Event Pass, add confirmed event details, and try different templates.

These editable templates do not identify qualified sponsors. A reference does not establish budget, interest, or a prior relationship.

Want AI-written copy with credits?

Open the separate authenticated composer for a real model request. It requires your verified account, API key, an authorized image, and confirmed facts. The result stays pending review; it is never sent automatically.

What does a credit cover?

The authenticated API uses one credit per successful reference, template, or render request. Failed requests are refunded. Public preview searches and account management use no credits. Sending a reviewed draft to your verified email does not consume a credit.

Can I buy more credits or subscribe?

Not in this beta. Paid prices and checkout are not available yet. The introductory grant is one-time and does not auto-renew.

Does the beta send emails?

Yes, after verification and review, the creator can send a rendered draft only to the verified account email. There is no public relay or automatic campaign send.
