How to send emails and avoid them being classified as spam
Whenever I send emails from my domain using PHP it goes to spam , when ever user register to my site I send them message saying welcome along with a image and Facebook Url,
No I Not spamming. No my IP is not blocked by any spam guard service.
What I need to do so that whenever I send email it goes to inbox and not in spam or junk.
PS. When I send email without any URL it goes to inbox.
I am assuming you are using a valid (with valid I mean theoretically reachable, valid domain etc.) from-address. If not, this should be the very very first thing to do.
You should have a proper SPF for your domain like:
example.com. IN TXT "v=spf1 a mx -all"
- or -
example.com. IN SPF "v=spf1 a mx -all"
Third: It is always good to write some "normal" text in your email. Most scanners determine a ratio between links and text. If it is to high your mail could be spam. Additionally it is always a good idea to provide the user with some help and info. :-)
If this does not help look at the headers of your "marked as spam" mail. Sometimes you can find some kind of "score" showing the spam-probability the scanner calculated. With this value you can try out what is wrong with your mail.
You should visit the "major webhoster" that's marking your mail as junk. They all have bulk sender/postmaster help and guidelines to help you get legit email through.
Of course, telling your users to check their junk/spam folders for the registration email is another thing you should be doing. Everyone else does this, no reason you shouldn't tell your users to expect an email within [x time] and to make sure it's not in the junk folder if it's not in the inbox by that time.
Finally, maybe you should check out our canonical spam thread - if you have a better idea of what people do to fight spam, it should help you make your registration emails look less like spam.
