# Sending domains

Authenticate your domain and build a reliable sending reputation.

## Why add a domain

A verified sending domain lets Email Bump send as your brand and gives mailbox providers the authentication signals they expect. It also removes the shared-domain testing limit.

## Add a domain

1. **Open Domains** — In the dashboard, go to **Settings → Domains** and choose **Add domain**.
2. **Enter the root domain** — Use a domain such as `acme.com`. You can send from addresses on that domain after verification.
3. **Copy the DNS records** — Add every record exactly as shown at your DNS provider, then return to Email Bump and check verification.

## Add DNS records

Email Bump provides DKIM and mail-from records for the domain. DNS updates may be visible within minutes, but some providers can take up to 48 hours to publish changes.

> ⚠️ **Do not remove existing mail records** — Add the records Email Bump provides without replacing records used by your current inbox or other sending services.

## Branded tracking

Branded tracking uses `links.yourdomain.com` for tracked links. This step is optional; until it is active, sends use the shared tracking domain.
