Why do emails end up in spam?

Understanding why emails end up in spam is the first step in preventing it. There are several reasons why emails might be flagged as spam…

  • Poor subject lines

Subject lines that seem suspicious or overly promotional are more likely to trigger spam filters. Phrases like "Free", "Guaranteed", or excessive use of exclamation marks can raise red flags, and get your email sent straight to the dreaded spam folder.

 

  • Sending from an unverified domain

If you're using a new or unverified email domain, your emails are more likely to be flagged as spam. Spam filters use domain reputation to determine whether or not to trust an email.

 

  • Lack of authentication

Emails that aren’t properly authenticated, for instance, missing DKIM or SPF records, are more likely to be flagged as spam. These authentication methods help prove the legitimacy of the email’s sender.

 

  • Content and links

Emails with content that contains too many links or attachments, or that resemble phishing attempts, are often marked as spam. This includes emails with misleading or irrelevant content.

 

  • Inconsistent sending patterns

Sudden spikes in email volume, particularly from new senders, can make spam filters suspicious. It’s best to gradually increase email volume over time if you're running a campaign.

 

  • High bounce rates

If a lot of your emails bounce back (because of invalid addresses or incorrect domains), it can negatively impact your sender reputation and increase the likelihood of future emails being flagged as spam.

How to prevent emails from going into spam

Now that you know why emails end up in spam, here’s how to avoid it and get on top of your email management system. 

1. Verify your domain

Make sure your domain is authenticated with SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance). These methods help prove that your emails are legitimate and not from a malicious source.

 

2. Check your email list

Make sure you’re sending emails to valid addresses. Regularly clean your email list to remove invalid addresses and minimise bounce rates. Also, avoid purchasing email lists, as they often result in high bounce rates and spam complaints.

 

3. Write clear, relevant subject lines

Write subject lines that clearly reflect the content of the email. Avoid overly salesy language and steer clear of using all caps or excessive punctuation, which can trigger spam filters.

 

4. Personalise your emails

Emails that feel personal and tailored to the recipient are less likely to be marked as spam. Use your recipient’s name, and make sure the content is relevant to them.

 

5. Include an unsubscribe option

Always provide recipients with an easy way to opt out of receiving further emails. Not only is this a legal requirement in many countries, including the UK, but it helps maintain a good sender reputation.

 

6. Monitor your email performance

Keep track of how your emails are performing. High open rates and low bounce rates signal to email providers that you’re a legitimate sender. If your emails consistently go unopened or are marked as spam by recipients, it can harm your sender reputation.

 

7. Avoid spammy content

Stay away from excessive links, large attachments, and phrases that might look spammy (like "free gift", "limited time offer", or "urgent"). Keep your emails clean and focused on the recipient’s needs.

Choosing the right and best email management system, taking proactive steps to prevent your emails from being flagged as spam, and knowing the common mistakes to avoid, can greatly improve your email deliverability.
