This add-on is a game-changer for sending bulk emails right from Thunderbird. I love how it gives you full control over sending rates and even has smart batching and cooldown options to avoid spam flags. It’s not perfect—campaigns disappear if you restart—but for a free tool, it’s incredibly powerful and well thought out. Great work on making email campaigns this accessible.
