Your new subdomain will be the email address you'll send marketing emails from. You can find subdomains as a prefix in front of a primary domain. For example, the “mail” in hello@mail.hive.co is the subdomain, and the "hive.co" is the primary domain. To learn more about why using a subdomain will boost your open & click rate, check out this blog!
Getting Started
*Make sure you or someone on your team (likely the person who manages your website) has access to your DNS registrar/provider and your Hive account.
Notes:
It can take 24 to 48 hours for DNS changes to propagate
Until your domain is verified, emails will be sent from a mail@hive.co subdomain
If your domain still isn't verified after 48 hours, please email hello@hive.co
Deciding on a Subdomain
On your Email Settings page, type in the address you'd like to use in the Custom "From" Email Address section then click Save.

Your subdomain should be in the format of:
[something] @ [subdomain].yourdomain.com
Note: "subdomain" is not an example, but simply a placeholder for the subdomain you choose
Below are some common examples of subdomains you can use:
[anything you choose]@[anything you choose].yourdomain.com
Example: If your company is Hightown Media, and your website/email domain is "HightownMedia.com" then the format of your subdomain could be hello@mail.hightownmedia.com
Verify Your Subdomain in Your DNS Provider
Once you've clicked Save, the page will refresh and your custom domain settings will populate in Hive. In order to let Hive send emails from your custom subdomain, you need to add the records that populate in Hive to your DNS provider.
Choose from the dropdown to see the records formatted for your specific provider. Then copy and paste the records to your DNS provider to verify your domain.

Editing the DNS settings of Common Providers
Here are third party step-by-step guides for adding records to common DNS registrars.
NameCheap: TXT, CNAME
Network Solutions: TXT, CNAME (follow Step #3 for both)
Dreamhost: TXT, CNAME
Once you’ve added the values from Hive to your DNS provider and they’ve propagated, your domain will be verified!
