Whitelist: It is list of domain names or IP addresses which are allowed to pass through the spam filter without being checked.

Blacklist: It is the list of domain names or IP addresses of known spammers which are blocked by ISPs from sending mails.

ISPs and Individual users use both lists to determine whether your email gets delivered as you intend, to the inbox instead of the junk folder and with images intact instead of blocked.

How do we know that we are blacklisted

There are some tools like Spam Corp, MAPS Realtime Blackkhole list which check multiple blacklisted databases to see if your domain or IP address appear on them.

How to Seek ISP Whitelisting

Each major ISP maintains its own whitelist, so you will need to visit their respective websites and submit their forms. Your email ESP should be able to provide you links to the whitelist application forms for the major ISP's and email address providers.

Below given are details regarding the whitelisting.

ISP whitelists usually include these kinds of data:

  1. Email addresses listed on their users' personal whitelists
  2. IP addresses, domain names or email addresses from senders certified by third-party agencies such as Bonded Sender, Habeas or Goodmail
  3. Senders who apply and qualify for a whitelist after following a set of instructions or protocols

Desktop clients such as Outlook and Eudora rely on individual users to compile whitelists. However, Web clients AOL and Yahoo! Mail allow you to apply for whitelisting status. MSN/Hotmail uses Bonded Sender data to determine whether and where to filter email.

For other ISPs, we have to look on their corporate Web sites for "postmaster" or bulk-email information and see if they offer whitelisting. Whitelisting doesn't guarantee that your email will be delivered the way you want, but it improves the odds.

Yahoo! Mail:

In addition to individual whitelists based on the user's address book, Yahoo! Mail operates a general whitelist.

  1. On the Delivery Problems page of Yahoo! Mail's online support, you have to fill out the form and submit it.
  2. In about 15 minutes or so, you will receive a detailed questionnaire that asks you about your sending policies, procedures, etc. It could reveal some gaps in your email program. Fill out the form as best you can and submit it.
  3. You might or might not hear back from Yahoo! about whether you have been whitelisted. Open a free account and send a test message to it from the address you normally use to send bulk email.

Like Yahoo!, AOL has its own whitelist. It doesn't guarantee that whitelisted senders will always get their messages delivered to the inbox instead of the junk folder. But, whitelisted senders who meet stricter volume and complain criteria might qualify for AOL's enhanced whitelist. Email messages from those senders show up with hotlinks and images enabled instead of blocked.

  1. Read the Conditions to Bulk Sender Status page first. Check the box indicating you accept AOL's guidelines, and press the Accept Guidelines button.
  2. You will be taken to a form asking for contact information and the IP addresses you use to send bulk mail. Fill out the form and submit it. This will also set up a feedback loop that will send spam complaints to you for action.

MSN Hotmail:

MSN Hotmail/Windows Live Mail does not operate a whitelist. They evaluate inbound e-mail through various technologies and processes. They do not provide a “free pass” to any senders via a whitelist. However, we do partner with Return Path, Inc., who provides us a safe list via their Sender Score Certified program.

For additional ISP's and corporate whitelists, you will have to do a Web search or contact them directly for more information. It might be worth it to request whitelisting on selected corporate networks if a number of your list members have email addresses on these corporate networks

How to Get on Individual Whitelists

You must probably have a line in your email message near the top, asking the recipient to add your sending address to his or her address book or contact/safe-sender list. But, that's almost too late in the process.

Also, putting the line at the top means readers who read only a portion of your message in the preview pane are not getting the information they need to decide whether to open your email to full size or even scroll through the preview pane.

  1. Include a whitelisting request right at sign-up, on your subscription or site-registration page. You need to get into that address book even before you send out the subscription confirmation.
  2. Move the whitelisting-reminder email in your email message to your email-administration center farther down in the message.
