Bulk Emailers

I’m looking to create a bulk emailer in an existing RoR application
and I’m having a hard time finding resources out there on how to
accomplish this. It will be for a mailing list of 12k+. Any advice
or guidance would be greatly appreciated.

Try some combination of ar_mailer and BackgrounDrb.

I’m curious about this too. We send around 15k system emails a day. My
concern is whether running these would impair the app’s performance, at
least in other areas.

Because of this I decided to use script/runner to run the process in the
background. It seems to run pretty descent on my dev machine.

Curious of anyone else’s experience in doing this.
