Short answer

How can I test my email templates using AI?

Tell your AI to find a specific template in Postmark and send it to your test email. You'll get the exact HTML rendering in your inbox to check for layout breaks or content errors.

The results of testing

What you get from testing

The AI handles the technical triggers so you can focus on the visual output.

VALIDATION

Visual layout checks

The AI sends the template to your inbox. You see exactly how the HTML renders in a real mail client.

CONTENT

Data accuracy

Verify that your template variables populate correctly with the data you provided in the chat.

SPEED

Instant iterations

Instead of manual API calls, you just ask your AI to resend a modified version to your test address.

HUMAN

Final visual sign-off

The AI cannot see the rendered email in your inbox. You must perform the final visual inspection yourself.
