Short answer

How can I send transactional emails through my AI?

You can trigger emails using existing templates or send custom messages directly through your chat. Your AI also checks if an address is valid before you hit send to prevent bounces.

Email outcomes

What you get

These are the results of your requests.

DELIVERED

Direct email triggers

Your AI uses Mailgun to send specific messages to recipients. You get confirmation once the request is processed.

VALIDATED

Clean recipient lists

The AI checks email addresses for deliverability. This stops you from sending mail to dead or non-existent accounts.

TEMPLATED

Consistent branding

Your AI pulls your pre-made Mailgun templates. This ensures your transactional mail looks exactly how you designed it.

HUMAN

Manual review needed

The AI cannot decide which emails are high-priority. You must tell your agent which specific template or recipient to use.

The workflow

What your AI does when <the thing arrives>.

The AI handles the technical handshakes with Mailgun so you can focus on the content.

  1. Check address validity

    Before sending, your agent checks if the target email is real and reachable.

    validate_email

  2. Fetch email templates

    Your AI looks up your Mailgun templates to find the right layout for the message.

    get_templates

  3. Send the message

    The agent pushes the email through to the recipient using your Mailgun credentials.

    send_email

  4. Confirm delivery

    The AI reports back whether the email was successfully handed off to the Mailgun API.
