What's New?

v4.9.0 has focused on two things: Bounce Handler and Mass Mailing Speed

Bounce Handler has been given a well-deserved focus of our attention to make it better than ever:

  • Bounce message filtered has been updated and improved
  • Per-list settings for scoring, threshold and "decay" rates
  • Decay Rates! (how much a bounce score is lowered, for each mass mailing you send out, to keep good addresses out of your Bounce Scorecard)
  • Amazon SES Support
  • A new chapter in the Dada Mail Manual, devoted to the Bounce Handler. If you have a Never-Ending Subscription to Pro Dada/Dada Mail Manual, read it right now:


Mass Mailing has also been given a healthy dose of optimization, leading to some good speedups, while using less memory. We dug deep:

  • A new option to use a faster, up 10x faster (but 100% compatible with the old) templating engine. Read more:


  • Amazon SES sending is now around 3x faster, thanks to our own brewed module to send messages with a persistent connection
  • A nasty memory bug fixed, which was eating up memory and slowing down (or possibly stopping) mass mailings
  • A ton of work, to squeeze out every bit of performance. Here's some more details:
