Mail Merge P

Mail Merge P (Mail Merge with Preview) is a Thunderbird add-on to send bulk emails based on data provided in a spreadsheet. It uses the nunjucks templating engine.
Mail Merge P is a fork of the add-on Mail Merge for Thunderbird by Alexander Bergmann. It is developed independently by Jason Siefken.

- Better handling of identities
- Fixed error when updating settings

Some add-ons ask for permission to perform certain functions (example: a tab management add-on will ask permission to access your browser’s tab system).

Since you’re in control of your Thunderbird, the choice to grant or deny these requests is yours. Accepting permissions does not inherently compromise your browser’s performance or security, but in some rare cases risk may be involved.
