Updated: May 1, 2026 • 5 min read

Setting up a custom domain with ThePost is straightforward and takes just a few minutes. Follow these steps to connect your domain and start sending emails from your own address.

Step 1: Add your domain

You'll need to add three DNS records to your domain registrar:

DNS propagation can take up to 24 hours, but typically completes within 5-10 minutes. You can check the status in your domain settings.

Step 3: Verify and activate

Once your DNS records are configured, click "Verify" in the domain settings. ThePost will automatically check your records and activate your domain. You'll receive a confirmation email once the domain is ready.
