Send alerts and recovery emails through your own SendGrid, Mailgun or Postmark account, from an address on your domain.

**Plan:** Enterprise. Other plans use Cart Whisper's built-in sender.

## How it helps

* Emails come from your own address, which shoppers recognise.
* Your provider's dashboard shows delivery details for every email.

## Built-in sender (default)

With **Cart Whisper (built-in, no setup)**, emails are sent from a Cart Whisper no-reply address and use your **From name**, or your store name if it's empty. Shoppers' replies to recovery emails go to your configured support/ticket email, or your store email if no support email is configured.

## Set it up

1. Set up a verified sender or domain with your provider first.
2. Go to **Settings → Email alerts → Sender** and choose **SendGrid**, **Mailgun** or **Postmark** under **Provider**.
3. Paste your API key. For Postmark, use the **Server API token**. For Mailgun, also enter the **Mailgun domain** (for example mg.yourstore.com) and choose the **Region** (US or EU).
4. Enter a **From email** that's verified with your provider, and a **From name**.
5. Click **Save**, then send a test from **Preview and test**.

## Troubleshooting

* **"API key missing" or "From email missing":** fill in the field and save.
* **The provider returns an error (for example 401 or 403):** the key is wrong or the sender isn't verified. The full message is shown in **Delivery**.
* **Postmark:** emails use the default "outbound" message stream.
* Delivery rates depend on your domain setup (SPF/DKIM) and your provider, so Cart Whisper can't guarantee inbox placement.
