What factors influence domain reputation?

Domain reputation is shaped by the cumulative signals your domain generates across all sending activity. The major factors include:

Authentication alignment with SPF, DKIM, and DMARC passing consistently. Engagement metrics showing recipients open, click, and interact positively. Complaint rates staying well below the 0.1% threshold that major providers enforce. Bounce rates indicating clean, validated lists. Spamtrap hits signaling poor list hygiene or purchased data.

Providers also watch content patterns for spam indicators, link reputation of domains in your messages, and sending consistency versus erratic volume spikes.

Your domain reputation is the sum of every voyage your flag has taken. Each signal adds weight to the overall assessment, and providers never forget a shipwreck.
