What is an Email Block?

One of the instances that tend to annoy any digital marketer is when their emails get blocked. You can spend a lot of money setting up and targeting your buyers, but blocked emails can cause these costs to shoot up and be a point of contention between you and your marketing team.

It’s important to understand why certain emails get blocked and why they happen so. Once you do that, it becomes easier to create checkpoints that ensure they don’t happen again. Here are a few reasons emails tend to get blocked:

Reasons for Blocked Emails

As you may expect, spammy-looking content is one of the main reasons for your email to be filtered. The following characteristics easily identify spam emails:

  • an unfamiliar email address in the field that says From
  • a typo in the Subject
  • subject lines written in ALL CAPS
  • a high and typically bold font size and
  • pure marketing promo and sales material

Furthermore, have you considered the links you include in your emails? You may wonder why you should be concerned about the links if they come out of your site. Here are five pointers that could help you reduce the block rate:

1) The content: First and foremost, ensure that the content of your emails is super relevant to your buyer. Anything you send must be centered on the buyer’s requirements. Because a top-of-funnel client isn’t engaged in your recently launched promotion, marketing materials, or demo, why are you sending it to them?

Trying to isolate the buyer by giving them stuff they aren’t ready for will instantly mislead the receiver about why they signed up for such emails and may even wonder if they did sign up for such emails in the first place! If this occurs, the recipient may designate you as spam, which can significantly impact your image.

Make creating exciting and valuable content a goal, and afterward evaluate your content for display, HTML mistakes, link issues (do not use URL shorteners), and mobile design usability. Don’t forget to conduct A/B testing on different sectors of your database.

2) Frequency: Marketers will send an email to their subscribers regularly. While it may appear to be a sound plan, executing too many marketing initiatives is a symptom of strategic market generation – and it costs you far more than energy and time.

Furthermore, trying to send emails too commonly can often lead to recipients obstructing messages in their internet browser, network managers blocking the originator at the network layer, or, worse, your information is added to a ban list for mailing too frequently.

So, send with caution and avert least until you’ve gotten to know your readers and have their authorization to communicate frequently.

3) Volume: Sending large amounts of mail to a certain network or domain might frequently look like a cyberattack on the email system and server. This is particularly true for business-to-business senders that send to small company domains.

Most of the time, these email services will put the originator to their block or watchlist due to delivering too many messages in a brief period.

4) Lists - Purchased & Old: Due to the low quality of the addresses on the list, both old and acquired lists have a significant possibility of having your emails banned or blacklisted. These lists may contain incorrect email addresses, invalid domains, and even spam traps.

Most of these individuals either didn’t volunteer for the email list or did not expect it. This frequently results in an email being banned at the individual or network level. Always collect statistics up to date - test it regularly to confirm that the individuals on your database need to be on it and that you are not infringing any privacy laws.

To Wrap Up

The factors stated above are only a starting point for determining why a mail was restricted or blacklisted. It takes a little time to understand the procedure but discovering the truth can frequently get your email received and the targeted buyer. The first step toward attracting a buyer and increasing revenue is reliability.

Get yourself an email service provider that makes it easier for you to create and deploy the ones that work for you, and soon, you’ll notice an uptake in the subscribers and their reactions.
