Review on Bouncer by Devin Maselli

I like that you can set up rules for different types of emails (like newsletters) as well as sending out mass mailings with one click in bulk mode which helps streamline our processes at work.

It's also very convenient when it comes time to unsubscribe from mailing lists because we're able to do so without having to contact each individual person individually - just remove them all together once they've been removed from my contacts folder after hitting "Unsub." The only thing about bouncers/deliverers are their prices; however if this service fits within what budget works best then go ahead & use it but don't be surprised when fees start adding up quickly over many months of usage. We have had problems keeping track of who has opted-out vs. those actually opting themselves off.
