“The ongoing ‘spam wars’ have a side effect: ‘friendly fire’ casualties in the form of legitimate mail getting improperly blocked by over-zealous filtering. Verified opt-in mail, even mail the recipients paid to get, is being lost in alarming percentages.

Inbox Providers Love Us Too!…

“Outblaze supports ISIPP’s SuretyMail database because it gives us factual and reliable information about senders. Information such as whether a sending site publishes SPF records and whether it is personally known to ISIPP as a responsible sender that maintains and furthers best current practices. SuretyMail is a convenient tool that helps us make decisions about accepting and processing email from senders who are vouched for as responsible mailing list operators.”
– Suresh Ramasubramanian, Security and Antispam Operations Manager, Outblaze

“Having SuretyMail provide information about whether a sender publishes SPF records is an important new direction for DNS-based email delivery information databases, and we’re very pleased that ISIPP has chosen to do this, and happy to work with them in providing unique SuretyMail accreditation codes for SPF publishers. It is exactly this sort of cross-industry pollination which is going to help make sure that legitimate email gets delivered and that fraudulent email does not.”
