About a year ago I read something somewhere that gmail, and other provides such as hotmail, do not like to see many emails coming from the same ip address too quickly. These emails may end up in the spam folders. I have a membership site in which I will be sending updates to everyone on my membership site. I have the ability to control the number of emails that are sent at any time period. Does anyone know how many emails can be sent per time period without having any issues?
I will be sending the emails to the members when their membership plan is about to expire. I decided to send a max of 50 emails per hour. I think I will not run into any problems.
You can send thousands if a particular mail is signed by a mailer. Also sending it to opt-in mail list will guarantee that it will be delivered to recipient's inbox... Don't use php mail function.
This needs to be automated from my webscript. I send a notice to the member 5 days prior to when their membership is to expire. What is wrong in using the php mail feature?
