Customize the subdomain for your “From” email address

Article: 000053013
Updated: February 21, 2025

Why you should customize the subdomain for your rewritten “From” email address

With the latest email authentication requirements for email senders, we’re here to make sure your emails continue to get delivered to your contacts, even if you don’t have your own domain or can’t update the DNS records for your domain. 


To make sure 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 recommend that you customize a subdomain for this rewritten email address so that it better reflects your organization and looks more professional to your contacts, such as something like <carl@carlscoffee.ccsend.com>.

 

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

Examples:

marsha@halfmoonyoga.ccsend.com
sales@mikeslandscaping.ccsend.com 
info@sewingstudio.ccsend.com
boston@brickyardcafe.ccsend.com
shop@4alleyes.ccsend.com
bookings@oliviassalon.ccsend.com
adoptions@heartsandtails.ccsend.com
lessons@ventureguitars.ccsend.com
designs@annasinteriors.ccsend.com

 

To customize the subdomain used for your rewritten “From” address:

  1. Click the profile icon in the lower-left - or the three dots if you have the left-hand menu expanded - and select Account settings.
  2. Click the Account emails tab.
  3. In the Domains section, click Customize.

    My Account, Account Emails tab, Domains table, and Customize button
     
  4. (Optional) Update the prefix for your “From” address. This can be your name, department, location, etc.
  5. (Optional) Update the subdomain you want to use. This should represent your organization’s name, such as @halfmoonyoga, @brickyardcafe, etc. 
    Note: Your subdomain can be up to 63 characters long and can contain letters (a-z) and numbers (0-9). It cannot contain spaces or special characters, except for dashes (-).
    Exclamation Point IconImportant: You won’t be able to edit this customized subdomain once you save it, but you can create multiple “From” addresses with it. If you need to change your customized subdomain later, please contact our Support team.
  6. Click Continue.

    Customize your from address, prefix field, subdomain field, and Continue button
     
  7. Review the email address to make sure it looks how you want it, then click Confirm.

    Confirm customized from address
     
  8. Click Done.

    Customized from address success message and Done button
     



To create another email address with your customized subdomain to use as a “From” address:

  1. Click Add email address.

    My Account, Account Emails tab, and Add Email Address button
     
  2. Enter a prefix for the new email address.
  3. Click Create.

    Add New Email Address overlay, Prefix field, and Create button
     



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

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.
