How your “From” email address may be impacted by the latest email authentication requirements

Article: 000051400
Updated: February 21, 2025

Understand your “From” email address options to make sure your emails land in your contacts’ inbox

With the new 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.

 

Light Bulb IconTip: You can check your authentication status by going to the Account emails tab within your account settings. If you have your own domain, we recommend setting up an email address at that domain if you don’t already have one, and setting up self-authentication so you can use it as your “From” email address. Sending from your own domain builds your brand’s sending reputation and helps improve deliverability.

 


Why your “From” email address may have changed

We automatically rewrite your “From” email address with our shared ccsend.com domain, which has the proper authentication alignment to comply with the latest guidelines, to make sure there’s no interruption in your email delivery if:

  • You’re sending from a freemail domain, such as @gmail.com or @yahoo.com
  • You’re unable to access or update the DNS records for your sending domain
  • You’ve self-authenticated your emails, but haven’t published a DMARC policy yet
  • Self-authentication wasn’t successfully setup or activated within your account
  • The authentication records in your DNS have been changed or removed

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. The “From” address used for any automated emails or event-related emails is also rewritten with our shared ccsend.com domain.  If you want to customize the subdomain for this rewritten email address to improve your brand recognition and look more professional, such as something like <carl@carlscoffee.ccsend.com>, you can do so from your account settings

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

Light Bulb IconDid you know? In some cases, if a contact has an auto-reply/vacation message set, it's sent to your "From" email address instead of your "Reply-to" email address. Unfortunately, Constant Contact can't control where these auto-reply messages are sent, as it's entirely dependent on the recipient's email provider. If you want to ensure you receive these auto-replies, use an authenticated custom domain for your "From" address instead of a freemail domain, which gets rewritten upon send and does not tie to an actual email inbox.

 

Why you can’t see all of your email addresses when sending an email

Because of the new authentication requirements, you’re unable to send email from an unauthenticated address. As a result, you won’t see any of your unauthenticated domain email addresses as options to use for your “From” address when scheduling your email.

 

Do you send from more than one domain?

At this time, you can only send from one authenticated domain within your account, whether that’s a custom domain you’ve self-authenticated or a ccsend subdomain you’ve customized. If you need to send from multiple domains, you can remove self-authentication within your account settings or contact Support to remove your customized ccsend subdomain. This will allow you to choose from all of your domains when scheduling your email, and we'll rewrite each “From” address with our shared ccsend.com domain to comply with the latest authentication guidelines and maintain deliverability. For example, <carl@carlscoffee.com> will be rewritten to <carl-carlscoffee.com@shared1.ccsend.com>.

 

Not seeing your custom domain as an option?

If you want to use your own domain for your “From” email address, make sure you set up self-authentication and publish a DMARC policy for your domain. If you’ve already done so, but aren’t seeing your domain as an option for your “From” address, you can check the status of your domain authentication by going to the Account emails tab within your account settings. Be sure to reach out to your IT department or webmaster if you need help with updating your DNS records.

Customize your rewritten “From” email address

To make sure your “From” email address reflects your organization and looks more professional if you aren’t able to send from your own domain, you can customize the subdomain for your rewritten ccsend.com email address.

 

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. If you need to change your customized subdomain, please contact our Support team for assistance.

 

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. Enter a prefix for your “From” address. This can be your name, department, location, etc.
  5. Enter 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.

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 are 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, are not impacted. This allows you to continue receiving replies from your contacts and communications from Constant Contact regarding your account. Emails sent directly to the email address with the ccsend subdomain are undeliverable because it's sent to the Constant Contact email server and not to your inbox, so it is not included in the "Reply-to" drop-down menu.
