💡 What Is Email Domain Reputation?

Email domain reputation is a score assigned to your domain (like yourcompany.com) by mailbox providers like Gmail, Outlook, and Yahoo. It reflects how trustworthy your emails are based on:

• Bounce rates
• Spam complaints
• Engagement (opens, clicks, replies)
• Sending volume and frequency
• Authentication setup (SPF, DKIM, DMARC)

If your score is low, even the best cold email campaigns will go unseen.
