How To Know If Your Domain/ip Has Landed Up In Email Blacklists

Remove blacklist from IPs

There are ways to figure out if your infrastructure has landed in any email blacklists either ISP or independent. Sometimes it is a result of root cause analysis done by a marketer and other times it is an error message thrown by your ISP.

Most likely your network administrators inform you about blacklisting when the recipient server of your email throws back an error message of email rejection. You can also use an email blacklist checker tool to identify whether your domain or IP address is listed on any on the global blacklist databases.

The marketer will have to check if you have received an unusual spike in your hard bounces lately. Then go and check the bounce code errors for them and figure out if how many of those email addresses you mailed to are typos and spamtraps.

There are visual indicators in some ESPs to see how many common spam traps have you hit for your campaign.

Also check for your brands engagement ratio of number of opens to number of delivered emails for a particular segment. Low number of opens might also indicate that these were just recycled spam traps who receive emails but never respond. An email marketer should think about their segments and what kind of engagement they provide.

Some analysis on your email lists will likely give you insight on the faulty list collection practices that you may have due to which you might be receiving low quality email addresses.

What Is An Email Blacklist And Its Effect On Inboxing

Every day, there are tens of billions if not hundreds of billions of spam emails sent per DAY. With the number of spam emails sent dwarfing the number of legitimate emails that are sent its no wonder Internet Service Providers and other organisation work so hard to prevent spam from being spread around.

With such a large number of spam emails sent, blacklists are created to try to combat this and block IP addresses and domains that are known to send spam.

An email blacklist identifies and records, domains or IP addresses that have been sending spam, as per the standards of the blacklists owner. ISPs and mailboxes use them to protect their users from spam.

Here is the process whenever you send an email:

  • you send your email as a Sender to the Receiver
  • the email is received by an ISP who analyses it
  • the ISP checks if your domain is on the blacklist that they are using
  • the spam filters of the ISP evaluate your email
  • if your email passes the tests, then it is inboxed
  • In conclusion, your email can be rejected if it does not comply with the ISPs policies and/or if your domain is on the blacklist in use. The outcome of the analysis determines if your email will be inboxed or sent to the spam folder.

    Now that I have clarified the definition of a blacklist and how it affects inboxing, lets explore the different types of blacklists and a few examples.

    The submission process is simple, but the actual removal can be trickier.

    When you open up one of these options, youll get a form, wherein you can fill in various pieces of information, such as:

    • Your email server IP

    And most importantly, your reasoning for requesting removal.

    Youll have an open-ended area here, where you can document the steps youve taken to correct your infringing behavioror the reason why you think this blacklisting event was uncalled for.

    Monitor List Acquisition And Email Validation

    Workaround for Blacklisted Outgoing Mail Server

    When a user signs up to your email newsletter they need to know exactly what to expect from your brand and are their preferences being collected for mailing frequency.

    Dont scrape addresses from the internet or harvest any third party lists. Mailing to purchased lists is a sure fire way of getting in the email blacklists.

    The email ids collected need to be validated with Google and social plug ins which is a common practice used now. It would be great if you can send a verification email to their email ids to confirm your subscription as that will ensure that you are getting genuine users who are active on email.

    Mailing to invalid ids is a major reason for blacklisting to occur, hence make sure you are mailing only to valid email users. There are several email validation services to get that job done.

    How To Remove Your Ip From Yahoo Blacklist

    On the Yahoo blacklist? Cant send email to Yahoo?

    Trust me, you are not alone.

    Yahoo, Google, AOL, ATT and other ISPs are often targets of spammers. If you have a security issue on your server, you likely will get blacklisted by one of these major ISPs.

    Below I go over our process to removal your servers IP from the Yahoo blacklist.

    What To Do When You Get Blocklisted

    If you find yourself blocklisted, youll receive information for remediation within the failure event. This will usually include a URL to begin the blocklist removal process. If you still arent sure if youre on a blocklist, Its good to note that there isnt a need to run a third-party vendor that will run a blocklist check for you if anything your email service provider or account manager will give you more information.

    Most reputable BL vendors will have a clear self-service path to delisting that will involve sending over your contact information and any comments as to the possible reason for the block. Others will provide a case-specific email address and subject line.

    For major DNSBLs like Spamhaus and Spamcop, you can and should ask for specifics of the offending traffic and find out why the blocklisting occurred in the first place. Specifics like the From, Subject, or sending domain on a dedicated IP address. This can help you better target the issue and solve for it, and itll go a long way when communicating back on what youve done in consideration of being delisted. Granted most BLs like SORBs are automated, and a delisting request is likely to be approved for a period of time before they begin analyzing your traffic again for spammy behavior.

    Email checker tools and email validation in sign-up forms can also prevent such errors. Keeping a healthy contact list may help in avoiding spam traps and increasing email deliverability.

    How Your Ip Address Or Domain Gets Blacklisted

    Below is an illustration from Spamhaus, an operator or the biggest blacklist, showing the email blacklisting process.

    This is how the blacklisting process works. You send an email , and your ISP receives it. The company goes through the email and finds out if the IP address of the email sender is listed on the Spamhaus data.

    The ISP checks their spam filters to find out if there is anything in the email that they do not allow. If the email is found to have no spam or malicious content, the ISP decides to send the message to the recipients primary inbox.

    An email blacklist is just one of the tools that ISPs will use to determine if an email is legitimate. Every ISP has a unique policy that it uses to establish the legitimacy of an email.

    If an email is rejected, then it has probably not passed the ISPs policy. In the above diagram, the ISP has rejected the senders email based on the Spamhaus data and company policy.

    How Do I Know If My Emails Are Blacklisted

    Now is the time to confirm your listing in the third party blacklists services. But where to check? One of the ways is to check some of the obvious signs that you are blacklisted, just as mentioned in the “What Are Some Signs Of Being Blacklisted?” section.

    What Happens When Youre On A Blacklist

    Imagine that you have no clue your IP address was put on a blacklist.

    So you go about your regular email marketing activities and launch a campaign. Well say its a sales promotion and John is on the contact list. The email goes to his internet service provider , which checks your IP address against whatever email blacklists his ISP uses.

    Bingo, theres a match. Your email is discarded. John either never gets news of your sales promotion or, if he does, its delivered to the spam folder that he rarely checks.

    This blockage clearly has a harmful effect on email deliverability. Being identified as a blacklisted email sender can wreak havoc on your marketing efforts, especially if a large portion of it is email based.

    But reallyhow worried should you be? According to Omnisend Deliverability Manager Serhii Chernenko, it depends on what blacklist youre on.

    Some are more influential, respected and impactful, like Spamhaus, Cloudmark and Barracuda. You should be pretty worried if those have you listed, as impact would be significant, Chernenko says. Some RBLs will have way less impact on your deliverability or even zero impact, so it is important to monitor the biggest RBLs.

    Email blacklists are real-time lists that identify domains or IP addresses known for sending spam emails.

    Free mailbox providers, anti-spam vendors, internet service providers , and email service providers use blacklists to stop spam emails from entering their systems.

    • Bad email content. Some ISPs filter emails by using keywords as a basis. Expressions such as money-back guarantee, and free, as well as using multiple exclamation marks and all caps can get you blacklisted.
    • Poor email list management. Poorly managed email lists lead to unnoticed unsubscribe requests, which can get you flagged and blacklisted. If you dont check your email list, for instance, you might keep sending subscribers emails even if they unsubscribe, leading to them tagging you as spam.
