What is Spam Score?

Spam score is a metric used to assess the likelihood that an email or a web page contains spammy or unwanted content.

It uses algorithms that examine for characteristics like unreasonable hyperlinks, poor formatting, and certain keywords associated with spam. It also checks if your email address is authenticated.

The lower this measurement is, even negative, the better for your email deliverability and for your email to be seen by your recipient.

Anything above a 3 should not be sent out, and above a 5 the email will effectively stay unsent, and the greater the odds of being filtered out by anti-spam systems.

5 Tips To Reduce Spam Score

Improve Sender's Reputation

Keep a close eye on your sender's reputation by utilizing reliable sender reputation monitoring tools.

Identify the key factors negatively affecting your reputation and email deliverability, such as high email bounce rates or excessive complaint rates.

Once you've identified these contributing factors, immediately address and rectify them. This could apply to enforcing strategies to reduce bounce rates, securing your email list is up-to-date and properly maintained, and promptly addressing customer complaints or concerns.

Optimize Email Authentication

To boost your email deliverability and minimize the risk of your messages getting flagged as spam, it's essential to strengthen your email authentication protocols. Focus on implementing and configuring SPF, DKIM, and DMARC effectively.

These authentication tools play an essential role in verifying the legitimacy of your emails. By ensuring they are correctly implemented and configured for your email domain, you support the credibility of your messages. This, in turn, significantly reduces the chances of them being mistaken for spam.

Investing time and effort into authenticating your emails will enhance their reliability and increase the probability of reaching your recipients' inboxes.

Monitor & Test Deliverability

Consistently keeping an eye on your email deliverability metrics is required to achieve successful results. Maintain track of important indicators like bounce rates, open rates, and spam complaint rates to measure the health of your email campaigns.

Use email deliverability testing tools to assess how spam filters perceive your messages and make the required adjustments.

By testing and experimenting with various email elements, such as subject lines, content, or sending practices through A/B testing, you can find the most effective strategies to improve deliverability and lower your spam score.
