I''m building a feature for my app which allows the admin to compose an email and send it to a list of registered users (~1000). What is the best method for doing this? Should I create one email and BCC all the recipients? Is there a limit to how many recipients can be included in one email? or Should I send the same email to individual users? In the past I''ve had problems with legitimate emails being flagged as spam (usually on hotmail). Is one method more likely to be flagged as spam then the other? The app is hosted on Textdrive.

You''re much more likely to get marked as spam when you send from a dynamic ip address. Also make sure you can perfrom a reverse dns lookup on your host name. AOL will block all email (they won''t even reach the spam filter) if your hostname can be looked up.

Charlie, My app is hosted at Textdrive and shares an IP. euforea.com => 207.7.108.149 nslookup 207.7.108.149 => pendrell.textdrive.com Are mails send from a ???@euforea.com likely to be flagged as spam in this case? Is a dedicated ip a solution?
The most important factor is the ability for the recipients servers to do a reverse lookup on the senders hostname. I send out a fair amount of legitimate mailings to clients. There were alot of clients who weren''t recieving the mail I was sending because my mailserver was on an internal ip with a private host name. Once I changed it so that the a reverse dns lookup could be perfored, the mail reached the client without being marked as spam.

As far as I''m concerned, the best practice with mass mailings is not to do them -- **at all** -- **ever**. Rather, have a **separate** mailing list(s) associated with the site/business/product/whatever, managed with a mailing list manager. You need to get **explicit** permission for email, rather than assuming that anyone who gives you his email address desires every piece of email you could possibly send him. Having said that, is there a Rails-based mailing list manager already built, so a Rails site/application doesn''t have to use one written in a foreign language, such as Python?
