What Is a Sender Score?

A Sender Score is a numerical representation of your sending reputation on a scale from 0 to 100. Calculated by companies like Validity, it aggregates data from various Internet Service Providers (ISPs) to evaluate how trustworthy your emails appear. A higher score indicates a better reputation, which means ISPs are more likely to deliver your emails to recipients' inboxes instead of spam folders.

Your Sender Score is influenced by several factors, including your email sending practices, the quality of your mailing list, and recipient engagement. Consistently monitoring and improving your Sender Score can lead to better deliverability rates and more successful campaigns.

Why Does Sender Score Matter?

The importance of a high Sender Score cannot be overstated. ISPs use it as a key factor in determining whether to accept or reject your emails. A low Sender Score often results in emails being flagged as spam, reducing their visibility and effectiveness. Conversely, a high score boosts the likelihood that your messages will land in the inbox, increasing open rates and engagement.

Moreover, maintaining a good Sender Score helps in building trust with your audience. When subscribers consistently receive your emails, they are more likely to engage with your content, leading to higher conversion rates and a stronger brand reputation.

Factors Affecting Your Sender Score

Several key factors influence your Sender Score:

  • Complaint Rate: High complaint rates indicate that recipients are marking your emails as spam, which negatively affects your score.
  • Bounce Rate: A high bounce rate suggests that you're sending to invalid addresses, harming your reputation.
  • Spam Trap Hits: Sending to spam traps indicates poor list management and can severely damage your score.
  • Engagement: Low engagement rates signal to ISPs that recipients aren't interested in your content.

How to Improve Your Sender Score

Improving your Sender Score involves adopting best practices for email marketing. Start by maintaining a clean and updated email list to reduce bounce rates and avoid spam traps. Regularly remove inactive subscribers and ensure you have explicit permission from recipients before sending emails.
