Global Spam Trap Network

Tired of vague spam trap counts and lack of visibility? Us too. That's why we built our own trap network so we can offer a diverse set of data sources, collect and analyze millions of relevant messages per day, and deliver the value email marketers need to improve their program.


Complaint Monitoring

By collecting your feedback loop reports, we'll detect sudden increases in complaints that may cause deliverability issues, and help you suppress your most troublesome recipients.

Blacklist Alerts

Blacklistings can dramatically alter your ability to deliver mail to your customers. 250ok Blacklist was designed with speed and flexibility to notify you of issues before you send.

SNDS & Signal Spam

Integrate and automate your Microsoft SNDS & Signal Spam reporting to track spam traps and complaint rates at Outlook.com, Laposte, Sfr, and Orange.
