Enhanced Handling of Sender Addresses for Transactional Emails

We’ve deployed an improvement to how Freemius sends transactional emails to ensure higher deliverability and a more consistent experience for buyers.

Up until now, transactional emails were sent using either the custom sender address configured by the maker or the email associated with the Freemius account. While we’ve long supported DKIM domain authentication to help with deliverability, we noticed that incomplete or incorrectly configured DKIM setups could cause legitimate emails to get blocked or land in spam.

To address this and ensure important messages reach customers reliably, Freemius will now automatically send transactional emails from [email protected] whenever:

• DKIM authentication has not been completed, or
• the sender address does not match the authenticated domain, or
• the sender address is using some generic provider like Gmail, Outlook etc.

In these cases the email will appear as <[email protected]> {{ productTitle }} via Freemius, keeping your product branding clear for customers. Your Reply-To address remains unchanged, so all customer responses will still reach you directly.

If your domain is already authenticated with DKIM and you’re using email addresses from that domain, nothing changes — your transactional emails will continue using your configured sender. Otherwise you can optionally authenticate your domain if you want to keep using your own sender address.
