Creating an Email Address

In Mailofly, every outbound email requires a valid sender address specified in the from field. This guide covers RFC 5322 compliance, display names, and best practices.

Supported Formats

Mailofly supports standard RFC 5322 mailbox formatting:

1. Address with Display Name (Recommended)

"Sender Name" <sender@yourdomain.com>
Sender Name <sender@yourdomain.com>

Example:

{
  "from": "Acme Support <support@acme.com>"
}

2. Bare Email Address

sender@yourdomain.com

Example:

{
  "from": "billing@acme.com"
}

Domain Verification Requirement

When sending from custom domains, the domain portion of your from address (@yourdomain.com) must match an active, verified domain in your Mailofly dashboard. If you attempt to send from an unverified domain, the API will return:

{
  "error": "The domain 'yourdomain.com' is not verified in Domains."
}

If you do not have a custom domain verified yet, you can send from a connected Identity (e.g. your personal @gmail.com account or custom SMTP).

Reply-To Addresses

You can set a different destination for recipient replies using the reply_to field:

{
  "from": "Notifications <notifications@acme.com>",
  "reply_to": "team@acme.com"
}

Replies sent by recipients will automatically be addressed to team@acme.com rather than the sending address.
