Is My Email Blacklisted 3 Indicators

BlackList Check – How To Check to see if you are Blacklisted

If youre guilty of the things I mentioned earlier, then you might be already visiting your preferred search engine to search the phrases: check if my email is blacklisted or has my email been blacklisted.

I totally understand your frustrations. So, before you do in-depth research or read every article you encounter on the Web, here are three indicators your email is most likely blacklisted or spam listed.

What Is Blacklisting And Why Is It Bad

An email blacklist is a tool that servers use to decide which emails should be considered spam and which shouldnt. You have blacklists to thank for why youre not constantly clearing out fake promos and financial opportunities from foreign princes in your inbox. Theyre also why you might be struggling to reach your audience.

Essentially, each blacklist serves as a filter that helps servers trap spam and keep it in the junk folder where it belongs, with various ways of parceling out the spam from the other emails being sent. This is why you might know blacklisting by its other common name: spam trapping.

For the most part, blacklists do an excellent job at their intended purpose. But the ways that they decide whats spam and whats not means that sometimes well-meaning email marketers can also end up getting boxed out. When this happens, its usually due to one of three different specific traps that a marketer has fallen into:

  • Typo traps. If there are lots of typos in the email addresses in your contact list , spam traps are likely to assume that your list and your intentions arent so great. A few contact typos shouldnt harm you, but it does become a concern if its happening in excess.
  • Recycled spam traps. Beware of emailing dormant contacts. Email addresses that constantly bounce back are flagged as spam trap addresses, which could end up harming you if youre not paying attention.
  • What To Do So Your Emails Are Not Blacklisted & Placed Spam Folders

    The best thing you can do for your email marketing is avoiding a blacklist in the first place.Heres how to stay off blacklists:

    • Email Content What you send to your email subscribers keeps them interested and engaged in your emails. If youre sending out blanket emails to everyone on your list, you may get some spam complaints.

      Be sure youre sending what your subscribers are expecting from you and keep the content interesting to them by personalizing the emails and content.

    • Watch Email Campaign Stats Youre probably keeping an eye on opens and clicks, but also watch domain opens as well. If you see opens drop off significantly in a specific domain you should check your blacklist status.
    • Good lists Never, ever buy an email list. The addresses are at the very least stale and at the worst, spamtraps. Youll get more spam complaints and delivery issues than youll get business, so dont do it.

      Also, keep your lists clean by removing any bounced addresses or ones that are old and not performing. If someone hasnt opened your email in a while, you may want to remove them from the list.

    • Segment your lists To help ensure your email subscribers are getting what they need from your email marketing, break your lists up into segments.

      This could mean having lists based on where your customers live, what types of products they buy, or what their interests are. This will make it so much easier to send exactly the right email to each of your subscribers.
