Best bulk email add-on I’ve used.
I’ve tried other tools, but this one worked best. Great control over sending rates, smart batching with Random/Logic Mode, and dynamic placeholders make it ideal for safe, personalized campaigns in Thunderbird.

Simple, reliable, and powerful.
Mass Emailer is an outstanding tool for sending bulk emails directly from Thunderbird. It’s incredibly easy to use — you upload your contact list, create a template with personalized fields like {{name}} or {{email}}, and in just a few minutes, you’re sending fully customized messages.
I really liked how well it handles sending intervals using Random Mode and Logic Mode, which help avoid spam filters. Everything runs smoothly, and the best part is that you don’t need to rely on third-party services or pay for expensive subscriptions.
A professional, practical, and highly efficient solution. If you work with campaigns or need to send emails at scale, this add-on is simply perfect.

Mass Emailer is a great add-on that makes sending personalized bulk emails super easy. I’ve used it to reach out to dozens of contacts with customized messages for professional matters and personal matters, and it works like a charm—just plug in your data and it handles the rest. It feels reliable, simple to use, and blends right into Thunderbird without any hiccups. Perfect for newsletters, team updates, or event invites without needing a pricey email service. Highly recommend if you want control, privacy, and a no-fuss setup.

This add-on brings robust mass email capabilities directly into Thunderbird, with impressive control over delivery timing and sender logic. Features like Random and Logic Mode allow for smart throttling and batching, minimizing the risk of spam detection or server blocks. The ability to import dynamic recipient data and rotate subject lines adds solid personalization for campaign execution. While the loss of campaigns on restart is a limitation, the tool is highly functional for controlled bulk sending.
