Most Common Mistakes Businesses Make Regarding Email Deliverability

We all make mistakes. What is important is to learn from those mistakes and address them, especially in a business environment.

Here’s what we found are the most common errors:

  • Lack of awareness, most folks aren’t aware that deliverability even exists until they’ve already got a deeply entrenched problem. LB Blair
  • Lack of proper email authentication. Proper authentication (SPF, DKIM and DMARC) is indispensable nowadays. Jan-Philipp Benecke
  • The most common mistake businesses make regarding email deliverability is making panic-fueled, short-term decisions when faced with issues like a sudden drop in engagement. Instead of taking a methodical, long-term approach to identify the root cause and implement a well-considered solution, they often make hasty changes that can worsen the problem. – Alec Beglarian

Top Trends in Email Deliverability for 2024

There were some important changes in email deliverability.

While years ago was damn easy for anyone to send an email on behalf of someone else (email spoofing), things got serious, mostly because of increase in SPAM and related bad activities.

With the help of DKIM, DMARC, SPF those bad actors can not so easily do it anymore. So here’s what experts say for trends in email deliverability for 2024:

With the recent changes by Google and Yahoo, the top trend in email deliverability for 2024 will be the increased focus on authentication and compliance with new guidelines. Bulk email senders will need to prioritize setting up SPF, DKIM, and DMARC authentication, aligning their domains, maintaining low spam rates, and providing easy unsubscribe options to ensure their emails continue to reach recipients’ inboxes.

Alec Beglarian –

Yahoogle (Yahoo and Google) taking a big step towards a “no auth, no entry,” model. I think this is a sign that spam filtering has achieved a new level of maturity. One that I support because it makes the ecosystem safer for all of us, as email is a critical channel for malicious cyber attacks and scams, generally more than 80% in any given year.

Not to mention, AI’s ravenous appetite for processing power means there are probably new pressures to make existing products more efficient. Stopping the message at the gate, conserves processing power in both the short and long term as it pushes unauthenticed mail out of the channel.

Authentication – I think there will be more mailbox providers who will jump on this train and also change their policies.

The Impact of Email Content on Inbox Placement

Email is not only about servers and authentication. Content of the email is also very important in terms of Inbox Placement. It consists of a few things:

Different aspects will influence Inbox Placement:

  • insecure links (not using https)
  • trying to evade spam filters
  • too many images to avoid pattern matching
  • use of url shortners
  • balance between images and text
  • subscriber focused content

Email content has a huge influence, as the content and how it is received by the audience is the ultimate determinant of whether or not a message is spam. Recently I have seen Google spam filtering the majority of messages with insecure links, those using HTTP instead of HTTPS. This isn’t surprising since Google also announced that TLS 1.2 or higher would be required for SMTP connections to Gmail.

Additionally, if the content contains anything that even looks too much like a scam, or a tactic scams have used to evade the spam filters in the past it it is likely to land in spam. Examples include using images instead of text to avoid pattern matching, or including a large string of random characters in an attempt to bust the hash and avoid matching a known spam fingerprint.

LB Blair

Over the next few years, email will continue to become more personalized and less pre-packaged. Your email content should be “subscriber-focused” and factor in audience management, segmentation, and frequency. This approach will improve engagement and lower complaints, thus increasing inbox placement.

Alec Beglarian

Content can influence the inbox placement, but in most cases not by individual words, as it was the case back in the older days of the Internet. Modern filtering engines based on machine learning, looking of thousands of different things.
Generally strive for a good balance between images and text, avoid the use of URL shorteners
