aws-ses gem 和群发电子邮件：我是用 1000 个地址的数组调用一次，还是循环 1000 次？

Question

I have SES setup and am preparing my app to send out mass emailings of 600 - 1000 addresses per mailing.

I would like to know if I should call the send method once with 1000 emails, or call the send 1000 times with one email each.

Also, I'm on Heroku, with a 30 second execution time.

Thanks.

Answer 1

You shouldn't be doing anything remotely intensive as sending 1000 emails in a web response. I suggest using the Delayed Job gem. It will run the processes in the background by scaling a worker and turning it off when it's done. Since workers are charged per minute, you'll have at most a couple cents per month to pay since your task should be done in less than a minute and shouldn't run all that often. You also won't have to worry about the 30 second execution time.

Hope that helps!
