Customize the subdomain for your “From” email address

Article: 000053013
Updated: November 6, 2026

Create a custom .ccsend subdomain for your rewritten "From" address to maintain strong email deliverability while presenting a professional, branded look to your contacts

With the industry's email authentication requirements for email senders, we're here to make sure your emails get delivered to your contacts, even if you don't have your own domain or can't update your DNS records to be able to send from your custom domain email address.

To ensure there's no interruption in your email delivery, we automatically rewrite your “From” email address with our shared ccsend.com domain. For example, if you currently send from <carlscoffee@gmail.com>, your “From” address is rewritten to <carlscoffee-gmail.com@shared1.ccsend.com> when you send your email. We also recommend that you customize a subdomain for this rewritten email address to better reflect your organization and look more professional to your contacts, such as <carl@carlscoffee.ccsend.com>.

  4. (Optional) Update the prefix for your “From” address. This can be your name, department, location, etc.

It cannot contain spaces or special characters, except for hyphens (-).

Create additional addresses with your customized subdomain

At this time, you can only customize one subdomain to use, but you're able to create multiple “From” addresses with your customized subdomain within your account. This is helpful if you have multiple people, departments, or locations sending emails to different contact lists.

  1. Click the Add email address button.

    My Account, Account Emails tab, and Add Email Address button

Compare the rewritten "From" address and "Reply-to" address while editing your email header

Rewritten "From" address:

You'll see these customized addresses as options in the “From address” drop-down when editing your email header, including automated emails and event-related emails. Since you can't send from an unauthenticated address, these will be the only options available for your "From" email address.

"Reply-to" address:

Your “Reply-to” addresses, as well as the email addresses you use for your account and billing contacts, will not be impacted. This will allow you to continue receiving replies from your contacts and communications from Constant Contact regarding your account.
