Managing your senders is critical to ensuring your emails reach the inbox and reflect your brand. Each sender is made up of two key parts:

  1. From Address – The sender name and email address your recipients see in their inbox.
  2. Sending Domain – The authenticated domain used to send your emails and build your sending reputation.

If you’re using an integration with SendGrid, Mailchimp, or Mailgun, you must manage senders directly through your ESP’s platform.


Create a sender

When you first set up email, you’ll be prompted to create a default sender.

Default sender email

This is the email address used to send messages when no other sender is specified. You must have one default sender at all times.

To change the default, click the action menu next to a sender and select Set as Default.

Action menu to set a sender as default

Default sender name

This is the display name that appears in the recipient’s inbox (e.g. Acme Team, Maggie’s Newsletter).

Default reply-to address

The email address users will reply to. You can override this per email if needed.

Sending domain

This is the domain used to send and authenticate your emails. You must configure your DNS records to verify ownership and improve deliverability.

We strongly recommend using a subdomain (e.g. mail.yourdomain.com) to keep email reputation isolated from your main domain.


Add additional senders

You can create multiple senders to support different teams, brands, or message types.

Add sender button in settings

To create a new sender:

  1. Go to Settings > Email > Senders
  2. Click Add Sender
  3. Enter the sender name and sender email
  4. Enter your sending domain and configure DNS
    It may take a few minutes to auto-detect and verify DNS records.
  5. Once verified, use this sender in Messages > New Email by selecting it from the Sender dropdown

From addresses vs. senders

From addresses versus senders comparison interface

  • From addresses: These are the sender name and email shown in the recipient’s inbox. You can create multiple from addresses under the same sender, as long as they share the same domain.

    Example under mail.yourdomain.com:

    • news@yourdomain.com (Newsletter)
    • promos@yourdomain.com (Promotions)
  • Senders: Each sender has its own unique sending domain. This is helpful when you want to isolate deliverability between message types.

    Example:

    • mail.yourdomain.com (Marketing)
    • notify.yourdomain.com (Transactional)

Best practices

To protect your sender reputation and ensure high deliverability:

  • Use separate senders and subdomains for different message types:

    • mail.yourdomain.com for transactional emails
    • info.yourdomain.com for marketing emails
  • Avoid using your root domain (e.g. yourdomain.com) to send email. Always use a subdomain.

  • Monitor domain reputation and avoid mixing high-risk marketing sends with critical transactional messages.
