Gmail and Hotmail marked as spam

Question

First of all, I want to thank you for your time. I\'m having a hard time getting my head around this problem.

With reference to this thread we\'ve dediced to implem

Answer 1

It is also possible that if the new IP address has been previously blacklisted by Google or Hotmail or any of the third parties they use (even before it was owned by you), the blacklist is still in effect.

In addition to mxtoolbox.com, I'd also checkout Spamhaus's lookup (http://www.spamhaus.org/lookup.lasso). Many providers use their XBL, PBL, and DBL advisories to maintain a blacklist.

Answer 2

You should setup an SPF record for your domain. Google is only returning neutral on your SPF check.

Answer 3

You may want to look into DKMS/DomainKeys (and Microsoft/Hotmail has their own thing as well that is similar but different for Hotmail :P)

Answer 4

First, I would suggest using Swiftmailer over PHPMailer. But regardless, your issue isn't what software you are using to send your email. You should head over to http://mxtoolbox.com/ and see what it says about your email domain. You should have the correct reverse DNS setup, in addition to making sure you have a SPF record setup in your DNS.

It seems your reverse DNS is not setup correctly, at least not for koopte.be.

Answer 5

Spam issue because of following reasons

1)Shared hosting

If you are using shared hosting, PHP is not the solutions for this issue.try to contact your server providers.Some time your hosted IP treated as spam.Try to change the hosting providers, It may work fine.

2) More Links in your e-mail body

3 )Partial header(Always use reply-to,Ref Ans:TrentonMcManus)

4) Bulk E-Mailing

5) Spam Reporting(number of people who have clicked on your link as spam)

6) The message not to be too short or too long.

7) Sending From Blacklisted IP(hosting, and SMTP server) )

It may be new your IP address has been previously blacklisted by Google or Hotmail You can check Blacklisted ip or not from the site from here

8)Verifying sender IP

Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing, a common vulnerability, by verifying sender IP addresses.

Perhaps PHP not solutions for this. You can do Following things in php coding

1)Always use the from/reply to address

2)Add unsubscribe link in body

3)Avoid spam keywords.

4)The message not to be too short or too long.

5)Text version is better than HTML
