I’m wondering if anyone here has worked on an app that involved  
sending lots of emails (1000+ emails per hour) from inside the rails  
app. Did you use sendmail, an smtp server or a specialized service?

We don’t send lots of emails continuously, but we do have a daily  
‘fact of the day’ which we send out to a fair number of subscribers,  
via a cronjob that talks to sendmail.

I’d suggest considering a service such as [authsmtp.com](http://authsmtp.com). If you’re  
generating lots of emails, it is hard work to stay off the blacklists  
and keep your messages from being blocked as spam.

I use sendmail for some low-volume mail sending but would use authsmtp  
or something similar if volume was higher.

Michael & Fred,

Thanks for your feedback. I think the way I’ll do it is run sendmail  
until it starts hitting 100 emails per hour and then switch out to  
authsmtp.
