Answer 1

AWS throttles emails sent through EC2 servers . The throttle rate isn't published. Some EC2 IP addresses may have problems with blacklists too.

Ultimately what this leads to is "use SES".

Here's an unofficial how to bolt SES on , but the better option is to use the AWS PHP SDK to send email to SES .
