Hey everyone - need some advice.
I’m working on a website for a client and there is functionality where users can sign up for “lessons” that are to be sent to them based on a schedule they select via email. The sign-up and scheduling aspects are written in PHP and the user / lesson text data is stored in MySql. What I still need to do is write something to send the emails out on a daily basis. Should I use PHP to do this? Or is there something else I could/should use? I need to make sure the emails are not marked as SPAM, meaning they need to pass any reverse domain look-up tests. The process needs to perform well and be stable as well.
Any advice you could give would be greatly appreciated!
Thank you!
