### Connect and Test an Email Delivery Connection

Create a Mailrith delivery connection, save the email delivery service credentials, assign it to the right workspace, and send a test.

Mailrith does not hide your sender setup inside the campaign editor. Email delivery services are connected and managed from Email Delivery Connections. This is where you create the sender once and then reuse it in broadcasts, sequences, and automations.

Set this up before building a campaign. It is frustrating to finish a campaign and then discover that the sender has not been verified or the wrong workspace was assigned.

1. In Mailrith, open the workspace that should use the sender.
2. Click `Email Delivery Connections` in the left sidebar.
3. Click `Create Connection` in the page header.
4. In `Select Email Delivery Service`, choose the email delivery service you prepared.
5. In `Connect Email Delivery Service`, enter the connection name, From name, From email, workspace assignment, and credentials for that email delivery service.
6. Click `Save`.
7. From the connection row, click `Send Test Email` and send a test to an inbox you can check.
8. Click `Webhooks` on the connection row and follow the email delivery service setup instructions so bounces and complaints can flow back to Mailrith.
