Short answer

How do I send and test HTML emails with my AI?

Your AI uses the Resend connector to push HTML or plain text directly to recipients. You'll see the results of your template testing through direct email delivery. This setup lets you move from a prompt to a sent email in seconds.

The outcomes.

Where your requests land.

Depending on what you ask, your AI handles the heavy lifting or flags things for your review.

DELIVERED

Emails sent to inbox

The AI pushes your content to the Resend API. You get confirmation that the message is on its way to the recipient.

RENDERED

Template verification

The AI checks the HTML structure you provided. You get feedback on whether the code is valid and ready for dispatch.

FAILED

Error reporting

If a recipient address is invalid or the HTML is broken, the AI catches the error. You get a clear reason why the send failed.

HUMAN

Manual review needed

The AI flags complex layouts or sensitive recipient lists. You decide when a template is polished enough to go live.

The workflow

What your AI does when you request an email.

The AI acts as the bridge between your chat interface and the Resend API.

  1. Prepare the content

    Your AI takes your instructions and formats them into a clean HTML or text payload. It ensures the structure matches what the API expects.

    send_email

  2. Execute the send

    The AI triggers the actual transmission through the Resend connection. This moves your draft from the chat window to the mail server.

    send_email

  3. Validate the payload

    Before or during the process, the AI checks that the email data is complete. It looks for missing subjects or malformed HTML tags.

    send_email

  4. Confirm delivery

    The AI monitors the response from the API. It tells you if the message was accepted or if there was a bounce.

FAQ

How this task behaves.

  • 01

    Can the AI send emails without my permission?

    No. The AI only executes the send command when you explicitly ask it to via your chat interface.

  • 02

    Can the AI change my Resend API keys?

    No. The AI can only use the connection provided by Vinkius; it cannot modify your account settings or credentials.

  • 03

    Does the AI handle the actual email hosting?

    No. The AI uses Resend to dispatch the messages, but the actual mail delivery infrastructure belongs to Resend.

  • 04

    Can I send attachments through the AI?

    The capability depends on the specific tool implementation. If the tool only supports HTML and text, it cannot send files.

  • 05

    Will the AI automatically retry failed sends?

    No. If a send fails, the AI will report the error to you, and you must decide whether to try again.
