The problem is simple that the PHP-Mail function is not using a well configured SMTP Server.

Nowadays Email-Clients and Servers perform massive checks on the emails sending server, like Reverse-DNS-Lookups, Graylisting and whatevs. All this tests will fail with the php mail() function. If you are using a dynamic ip, its even worse.

Use the PHPMailer-Class and configure it to use smtp-auth along with a well configured, dedicated SMTP Server (either a local one, or a remote one) and your problems are gone.

If you are sending this through your own mail server you might need to add a  Sender  header which will contain an email address of from your own domain  Gmail will probably be spamming the email because the FROM address is a gmail address but has not been sent from their own server

One thing that I have observed is likely the email address you re providing is not a valid email address at the domain  like Nobody gmail com  The email should be existing at Google Domain  I had alot of issues before figuring that out myself    Hope it helps

Be careful with your tests  If you in your form you put the same email as the email address which must receive it will be directly in spam

Try changing your headers to this    headers    MIME-Version  1 0      r n    headers     Content-type  text html  charset iso-8859-1      r n    headers     From  successive testing gmail com      r n     Reply-To  successive testing gmail com      r n     X-Mailer  PHP     phpversion      For a few reasons     One of which is the need of a Reply-To and   The use of apostrophes instead of double-quotes  Those two things in my experience with forms  is usually what triggers a message ending up in the Spam box    You could also try changing the  from to    from    successive testing gmail com         EDIT   See these links I found on the subject https   stackoverflow com a 9988544 1415724 and https   stackoverflow com a 16717647 1415724 and https   stackoverflow com a 9899837 1415724  https   stackoverflow com a 5944155 1415724 and https   stackoverflow com a 6532320 1415724   Try using the SMTP server of your ISP    Using this apparently worked for many  X-MSMail-Priority  High   http   www webhostingtalk com showthread php t 931932   My host helped me to enable DomainKeys and SPF Records on my domain and now when I send a test message to my Hotmail address it doesn t end up in Junk  It was actually really easy to enable these settings in cPanel under Email Authentication  I can t believe I never saw that before  It only works with sending through SMTP using phpmailer by the way  Any other way it still is marked as spam    PHPmailer sending mail to spam in hotmail  how to fix http   pastebin com QdQUrfax

What we usually do with e-mail  preventing spam-folders as the end destination  is using either Gmail as the smtp server or Mandrill as the smtp server
