# Custom Email

> Send platform emails from your own domain using Mailgun, Postmark, Sendgrid, or SMTP.

**Estimated time:** 5-10 minutes

## Overview

By default, platform emails (invitations, password resets, notifications) send from Vapify's address. Custom email settings let them send from your own domain instead.

## Prerequisites

* A paid plan (Starter, Business, Scale, or Partner). Not available on Free
* An account with Mailgun, Postmark, Sendgrid, or an existing SMTP server

## Steps

1. Go to **Agency Settings → Email Settings tab**.
2. Enter your sender email address (e.g., `support@youragency.com`).
3. Select your provider and enter its credentials:
   * **Mailgun**: Private API Key (starts with "key-") from Mailgun's Settings → API Security.
   * **Postmark**: Server API Token from your Postmark server's API Tokens tab.
   * **Sendgrid**: API key with Mail Send permissions.
   * **SMTP**: server/hostname, port (587 for TLS, 465 for SSL), username, and password (use an app-specific password for Google Workspace or Microsoft 365).
4. Click **Test Connection**.
5. Once the test succeeds, click **Save Settings**.

<Tip>
  Mailgun and Postmark both offer free tiers and are the recommended starting points; check their pricing pages for current limits. Use SMTP only if you need a specific existing mail server.
</Tip>

<Warning>
  Never use your primary email password for SMTP. Use an app-specific password, and rotate API keys periodically.
</Warning>

## Troubleshooting

* **Test connection fails**: Recheck the API key for typos, confirm it has send permissions, and confirm your sender address is verified with the provider.
* **Emails not received**: Check the recipient's spam folder, and confirm your domain has SPF/DKIM records set up with your provider.
