email spam

In our previous article, we elaborated on a few reasons why your emails might be going to spam, specifically from the technical point of view. However, did you know that the content of your email also plays an important part in this? Sometimes, even if everything is perfect from the technical aspect, your emails can still end up in the spam folder of the recipients due to the faults of your content. Today we will share a few tips that will help you understand how to edit the content so that your emails go straight to the inbox. Let’s begin!


  1. Do not write the whole text with capital letters. It would be just fine to highlight a few things, but mostly try to avoid it in your email. Use common fonts (e.g. Arial, Verdana, Helvetica, Georgia, Tahoma, Lucida, Trebuchet, and Times).

  2. Be expressive if needed, but try not to be too expressive. The more exclamation points you use at the end of your sentence, the bigger the chance your email would not make it to the recipient.

  3. Make sure your text is readable. Think of what you want your readers to make out of your email. Too much highlighted, underlined, or bold text will only bring your chances of reaching the recipient’s inbox down. Draw the attention of your readers with the meaning of your content, but not the text styles.

  4. Do not replace the letters with other characters and do not use too many colors in your text. The best would be having just one color for your text, and a different color for your signature, if you wish. After all, it’s an email and not a peacock’s tail.

  5. Do not send emails that contain only the links or only the images with no text at all. Also, keep in mind that the attached images would not be a good idea either.

  6. Do not include video, Flash, and JavaScript elements in your email.

  7. The size matters. The emails that are bigger than 3 MB will most likely miss the inbox and go straight to the spam folder. Keep the size to the minimum, ideally, below 250 KB).

  8. Avoid sending your emails too often. Make it once or twice a week, and again, focus on the content, not the frequency.

  9. Make sure your email offers a possibility to unsubscribe, otherwise the recipient would mark your emails as spam, which would damage your overall credibility.

  10. Keep your email database relevant. By sending the emails to non-existent email addresses, the risk of being considered spam grows exponentially.

  11. The subject line of your email should be meaningful. Keep it short, do not use capital letters, and do not put a call to action there.

  12. Carefully check your text for grammar and spelling errors, structure, and clarity issues. Grammarly is a great tool to catch some of those things and make your text sound professional.

  13. Have you heard of spam words? Those are the ones that can be often seen in malicious and harmful emails. Therefore, upon detecting too many of them, the spam filters won’t allow your email to reach the inbox of the recipient (e.g. act now, 100%, #1, etc.)

  14. You can always check whether your email follows all the guidelines and would successfully end up in the inbox using many tools. One of them is Mail Tester.

  15. Analyze and adjust your email marketing campaign. See statistics on the deliverability of emails, clicks, and message complaints. By collecting this information, you can analyze the shortcomings of your newsletter and improve your email campaign.
