Overview
Mailspike isn't a traditional blocklist β it's a reputation scoring system. Each IP gets a dynamic reputation score across multiple tiers from poor to excellent. Different DNS return values correspond to different reputation levels, letting administrators set their own acceptance thresholds.
How It Works
Mailspike analyzes global email traffic patterns, scoring IP reputation across multiple dimensions including send volume, complaint rates, and bounce rates. Unlike simple blacklists with binary listed/not-listed states, Mailspike's multi-tier scoring provides a more nuanced picture of an IP's sending quality.
How to Get Delisted
Since Mailspike uses reputation scoring rather than a simple blocklist, improvement comes from better sending practices: lower bounce rates, fewer complaints, consistent sending volumes. Scores adjust dynamically based on recent behavior. Contact mailspike.net if you believe there's an error.
