SmartTemplates Pro 1 Year License


Buy an annual license for SmartTemplates Pro to support and grow this extension further. Unlike many Add-ons that stopped working caused by Mozilla's regular breaking changes of the Thunderbird platform, SmartTemplates strives to stay compatible with the current version of Thunderbird. We have successfully ported the Add-on for Thunderbird 91 for the ESR period 2021-2022, and are working on conversion to a native mail extension.

Annual License / Premium Features

The license is valid for 1 year from date of purchase. It does not renew automatically.

An annual license for SmartTemplates Pro gives you all premium features for a year. Any additional premium features added during the license term can also be used without restriction. The license fee enables me to support and grow the extension further and turn it into something even more awesome. In SmartTemplates Pro, any notifications "this is a premium feature" are turned off.

Alternatively, you can test drive many of the premium features with a cheaper standard license, but their functionality may be restricted.

Personal License Key bound to Email Address

The license is for your personal use and is tied to your email address. The email address must be defined as primary identity in any of your Thunderbird accounts. The validation of the email runs offline and the address is not stored on any server nor transmitted during use. With this mechanism, you can have additional email addresses, which do not need a separate key. You can install and use it on multiple email clients as long as they also have the primary address.


SmartTemplates Pro will be automatically updated via as usual. After the license term expires you can renew the license or purchase a standard license to keep using SmartTemplates .


If you have recently donated to the SmartTemplates project or have done contributory work, such as translating, you may be eligible for a free license key. Contact us via the email button at the bottom of our support pages.
