sendMessage / Swift Mailer Question

Hi Steve,

I'd check with your web host first, let them know you want to send out notifications to your users and ask if they have any daily limits on sending emails.  Maybe hosts have limits (regardless of how you send emails).  Google, for example, limits users to 2000 emails per day or 500 emails on the same BCC: https://support.google.com/a/answer/166852?hl=en

Regarding SwiftMailer plugins, we're not using any (unless they're enabled by default) and when we send lots of emails we do do it in a loop (with newsletter builder in blocks of x emails every y minutes on a cronjob) so you'd have to test to see if any of the anti-flood features work or if they work with your host.  Also, make sure that not having the email on the to: line might trigger more spam filters

Here's some links I found while searching that might be helpful:

• http://swiftmailer.org/docs/plugins.html
• http://swiftmailer.org/docs/sending.html
• http://stackoverflow.com/questions/12900155/swiftmailer-bccing-500-users

Lastly, if you need a good SMTP service MailChimp's Mandrill SMTP service is free for up to 12k emails a month: http://mandrill.com/

Hope that helps!

Hi Dave,

Thanks for the great info! I'll definitely check out those links. I wasn't aware of Mandrill free SMTP up to 12k emails/mo, pretty sweet.

Yeah, email blasts sent in a timed loop (in blocks) would be best for large volume messaging for sure.

This is a simple "Hey, there's a new article posted" notification on a low traffic site. I'd be surprised if the number of users getting notifications reaches 200. I did put a site email address in the to: line to avoid triggering spam filters.

The mail server is external so I was thinking if BCC's were batched to prevent flooding it would keep more of the load off this shared hosting account.

Thanks, Dave!

Best,
Steve
