How Do Email Service Providers Assess Credibility?
Email service providers use various metrics to assess a sender's credibility. These include:
Bounce rate: High bounce rates can indicate poor list hygiene or outdated email lists. Complaint rate: The number of recipients marking your email as spam. Engagement metrics: Open rates, click-through rates, and time spent on email are key indicators. Sender authentication: Proper use of SPF, DKIM, and DMARC records.
