Before you can use an email address as a "from address" in marketing emails, you must verify that the email address belongs to you or your company, or that you have access to it.
Please note: starting October 26, 2023, when you send an email from an unverified email address with a different domain than your connected email sending domain, HubSpot will require email verification for that address. Unverified email addresses are subject to a variable domain managed by HubSpot, a process which allows the automatic detection and removal of your unauthenticated domain without cancelling the send.

If you have a connected email sending domain, all existing and new from addresses at that domain are automatically verified. For example, if you have a connected email sending domain for domain.com, new and existing email addresses such as firstname.lastname@example.org or email@example.com are automatically verified. The email addresses of all active and confirmed users in an account are also automatically verified.
All marketing emails and transactional emails sent via HubSpot that do not use a connected email sending domain are subject to a variable domain managed by HubSpot. This enables the automatic detection and removal of your unauthenticated domain without canceling the send. This process may negatively affect how your recipients engage with your emails.

firstname.lastname@example.org, then HubSpot will modify the email address to use a HubSpot managed domain (e.g.,
hs-domain.com), so the resulting sending address will appear as:

The email address will be immediately eligible for use as a from address or test recipient of marketing emails in your HubSpot account.
