Create multiple from addresses

Updated

You may have messages that should come from different email addresses depending on your use case—onboarding emails from customer success managers, newsletters from a general company address, etc. You can add multiple from addresses to fit your needs.

Add multiple from addresses

To add a new from address:

  1. Go to Settings > Workspace Settings and select Email.
  2. Find the sending domain you want to add the new address to and click Add from address.

  3. Enter the sender name and email address.

After you add a new from address and the domain is verified, you can pick your new address using the drop-down next to the From label when creating an email.

Add dynamic from addresses

You can set a dynamic from address to personalize emails based on relationships between your company and your recipients.

For example, if you assign an account manager to each of your customers, you can add a liquid statement as your from address to pull in the account manager’s email: {{customer.account_manager}}.

To set a dynamic from address, you should include a liquid statement with a fallback from address to ensure your emails always reach your customers. In this case, your workspace would send from the fallback address when a recipient doesn’t have an assigned account manager.

  1. Go to > Workspace Settings and select Email. Click Dynamic addresses.
    the bottom of the workspace settings email page where dynamic from addresses are listed
    the bottom of the workspace settings email page where dynamic from addresses are listed
  2. Select Add Dynamic Address.
  3. Enter the display name and email address. You can use liquid in either field. For the email address, make sure you add a fallback from address for customers that don’t have the variable.

 Check that your dynamic addresses resolve to your verified domains

Starting June 8, 2026, if your dynamic address doesn’t resolve to a verified domain, your emails won’t send. Your workspace marks them as Undeliverable: from address does not belong to a verified sending domain. Until then, if the liquid renders an unverified domain, your emails will send from a Customer.io domain instead.

Here are a couple examples of dynamic from addresses:

{% if customer.account_manager != blank %}{{ customer.account_manager }}{% else %}accounts@example.com{% endif %}

In this example, the statement sets the email based on the account manager’s name and your sending domain.

{% if customer.account_manager_name %}{{ customer.account_manager_name | downcase | replace: " ", "." }}@example.com {% else %} noreply@example.com{% endif %}

Check where from addresses are used

If you’d like to see where a specific from address is being used, search for it in your Message Library.

This is a dedicated page in your workspace where you can locate specific templates by searching on keywords, as well as locate all message actions and broadcasts that are using a specific from address. You can also filter the results based on whether the message is actively sending or drafted.
