The limit of sending large number of emails

[Elham M]

Hi, We have a website that sends multiple emails on many events, but we have heard that if the number of sent emails becomes more than a limit in one hour, the receiving mail server (such as Yahoo! and Gmail) detects the sender as a spam sender and moves all of those mails to receivers’ spam instead of inbox. Our question is that what is that limit and How to ignore or eliminate this limit? Thanks.

This limit is set on external servers and cannot be controlled by you.

You'll need to go to the faqs or contact us section of each provider that you are concerned about and ask them directly as they will likely have varying levels, once you've got a decent cross section you can determine what a reasonable limit to set is.
