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.
