# Send email from your app (bring your own provider)

> Send transactional email via Resend, SendGrid, or similar using project secrets — no built-in email product.

# Send email from your app (bring your own provider)

Mythex does **not** include a built-in email sending product for your apps. Use a provider (Resend, SendGrid, Postmark, etc.) with your API key.

## Steps

1. Create an account with your email provider and verify a sending domain if required
2. Store the API key in [Secrets](/features/env-and-secrets)
3. Prompt:

```text theme={null}
Send a transactional email with [PROVIDER] using secret [ENV_NAME].
Trigger from the contact form / signup flow. Log failures without exposing the key.
```
