E-mail accreditation firm Habeas yesterday unveiled SenderIndex, an e-mail sender reputation-monitoring service created mainly for e-mail receivers using data from its network of more than 60 million IP addresses and domains.

By monitoring e-mail traffic from more than 140,000 e-mail servers, the service helps e-mail box providers and anti-spam companies better identify and categorize sources of spam and treat e-mail coming from them accordingly, according to Habeas.

The announcement follows closely on the heels of e-mail deliverability company Return Path unveiling Sender Score Reputation Monitor, a service aimed at helping e-mailers keep tabs on their reputations with inbox providers.

Using a consumer-credit-like scoring system of zero to 100

The announcement follows closely on the heels of e-mail deliverability company Return Path unveiling Sender Score Reputation Monitor, a service aimed at helping e-mailers keep tabs on their reputations with inbox providers.

Using a consumer-credit-like scoring system of zero to 100 — zero being terrible and 100 being perfect — the Sender Score Reputation Monitor helps e-mail senders tell how “spammy” they’re perceived by the ISPs receiving their communications.
