Whitelisting can help you to get your emails reach inbox instead of spam folder,
i will teach you now how to whitelist your self on some spam filter systems and some email providers.
First of all you must have a domain which have valid rDNS with your server, and you must have a web site on your domain. This may takes you some time, but i highly recommend you to make a fake marketing agency web site, i know this may sounds unethical and, maybe even, illegal ( okay, it’s hard to believe it could illegal since there is tons of hosting companies, web design agency and so on, which are not registered anywhere ), and you can make some simple looking web site explaining that you are providing email marketing services to your clients. Make sure you make it clear that you have a ZERO tolerance to spam and that all emails you have in your lists are generated by you, bla bla, opt in, bla bla, cpan spam, bla bla, just google some email marketing agency and see what they say :-). This will helps you A LOT to get whitelisted almost anywere.
Deciphering SMTP Errors
The SMTP errors that Gmail provides are key to mapping your path to getting off of Gmail’s blacklist.
For email delivery, the two main error codes are 421 and 550 errors.
421 errors are often temporary blocks. Most email servers will attempt to resend the email if they get a 421 error. If you quickly correct a spam or email flood issue, these blocks may resolve automatically. Left unchecked, Google may decide to block your email entirely.
550 errors are permanent failures. If you scan your logs for 550 errors from Gmail, they will often include links and additional information.
If you have 550 errors, you will likely need to take action before Gmail will remove your server IP address.
Requesting Blacklist Removal
Just so you know … Google does not want you to contact them.
Their forms are buried behind a series our questions that typically lead nowhere. Most of the time you will start with Gmail’s “My domain is having delivery problems with Gmail” form. As you answer the questions, you will typically end up in a dead-end.
However, with the right sequence of answers, you can eventually wind your way to:
This is where the action happens. Complete the form in detail but do not be overly verbose.
Once submitted, you can expect it to take 3-7 days to process. Often, you will not hear back from Gmail. Your email will simply start flowing again – provided you fixed the reason you were blacklisted in the first place.
Sometimes you have a lot of email – legitimate email – to send. Google does not clearly define what is bulk email. Typically, you will see an SMTP error code in the 400 series, such as:
421, "4.7.0", Our system has detected an unusual rate of unsolicited mail originating from your IP address. To protect our users from spam, mail sent from your IP address has been temporarily blocked. Review our Bulk Email Senders Guidelines.

Tricks to Getting Removed
We work on email delivery issues nearly daily. In our experience, if you do not fix these issues, your chances of getting removed from Gmail or any other blacklist is minimal.
- Reverse DNS Must Resolve to a Valid Hostname
- Your Server’s Hostname Must Have a DNS ‘A’ Record
- Do not blindly forward email to Gmail
- Make Sure DKIM/SPF are correct
- Stop the spamming!
You must make sure that whatever triggered the listing in the first place is stopped. If you do not, you will simply be re-listed.
