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.
