Email Detective — ESP Tracker

Herocredito

We've recorded 15 observations for herocredito.eu so far, but no ESP has crossed our visibility threshold yet.

To rule out spoofs, shared-pool false positives, and forwarded emails, we wait for one of:

• ≥2 observations of an ESP that's authorized in the brand's SPF record
• ≥3 observations across ≥2 distinct days
• SPF authorizes the ESP and the sender PTR confirms it (≥1 obs)

As more Email Detective users receive emails from this domain, it'll cross the bar and appear here automatically.
