I have a website that sends automated emails..alot of them. I am using phpmailer along with google apps email to send emails. My question is what is the right way to send emails without having them end up as spam and still easy to read? i have the Body and AltBody variables set up properly the Body has html and AltBody doesn't another question i have is how do i make line breaks in AltBody?

Is there a way i can send email to some ranking system and have it scored so i can see how email servers rank my messages so i can see if i will be counted as spam.

Thanks
