Dada Mail Four Point One Point Zero Released



What's New?

This release is all about zippy-zoomy performance stuff - most notably saving/caching commonly visited screens, so that they can be shown a lot faster that they usually are, with a lot less CPU time on the server side of things. The nice part about all this, is it's enabled by default - nothing else you have to do: Install/Upgrade and you automatically get the fancy goods.

There's been a little bit of performance tuning done with mass sending - but not a super bunch - you may see an increase of .10 to .25 seconds per message sent out. But, I'll take that - since this type of stuff adds up!

Other than that, there are some bug fixes bundled in - no security issues or anything like that. Just another rock-solid release, with more refinement, bundled tests and Dada Mail Goodness.

We couldn't have done it without your support of Dada Mail so, hey! Thanks for those who have supported us.

Pro Dada is the easiest way for you to support the Dada Mail Project. A $50 purchase of Pro Dada gives you access to Pro Dada and the Dada Mail Manual for life! Probably up there as one of the best deals of your life, too. Pro Dada comes with no footer back to our support site and no quotas of mailing lists or subscriber sizes. Did we mention it comes with the Pro Dada Manual? For Life? Well, that does indeed bear repeating.

Purchase at:


Pro Dada Four Installed - $100 - Bounce Handler included!

Get Pro Dada installed by us or get any current Dada Mail upgraded to Pro Dada Mail Four, for $100 and we'll install Mystery Girl, the Bounce Handler for Dada Mail as part of the install/upgrade for free (usually, it's $50 extra).

We'll keep upgrading it at your request for a year, but you'll have access to the Pro Dada Download and Dada Mail Manual for the life of the Dada Mail project.

Request an Install or Upgrade:


This deal will see it's longest day on June 21st and then make it's long way back to darkness, so take us up on it, while it's summer-fun time!

We're looking forward to receiving your feedback on Dada Mail Four Point One Point Zero.

Thanks for everyone's support for the past ten years! Yeah!
