If you'd like to send emails using your own domain, follow the steps below.

I'm glad you're checking out Warm Welcome's Domain Verification feature (aka DKIM). It's a bit geeky but if you want to brave your DNS settings on your own then do the steps in this order:

1. Go to Profile -> Settings -> Email
2. Select Custom Domain in the dropdown.
   
3. Type in your Domain Name (not your email address) and hit SAVE.
4. Scroll down and you'll be given DNS setup instructions and you will need to follow these with your registrar.
5. Wait 24 hours (propagating) and now email will be sending from your domain using your-first-name@yourdomain.com
6. Go ahead and send yourself a test email to make sure you like how everything is going through.
7. That's it! You're done

Grateful for you,
DJ and the Warm Welcome crew!
