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.
