When a recipient marks your message as spam, some ISPs offer a "feedback loop" so you can track complaints. Historically, feedback loops have been largely underutilized despite being highly impactful on your reputation.
250ok offers the industry's first centralized, comprehensive feedback loop monitoring tool to provide actionable feedback and an unparelleled view into your complaint rate trends.
Complaints are a primary contributor to your email reputation.
Gain Total Transparency
By collecting and analyzing your complaint feedback, we'll track complaints across any number of mail streams to highlight key trends including complaints by hour, day, ISP, IP address, domain, from address, and more.
Discover Real-Time Trends
Our real-time dashboard detects sudden increases in complaints that may cause deliverability issues. You can drill down to message-level data to identify abuse, account compromise, or problematic campaigns.
Analyze and Suppress
The ultimate goal is to suppress and remove problematic recipients, so we track recipient-level complaint frequency to analyze behavior and automate your suppression list.
Getting started is simple.
Enroll in feedback loops at supporting ISPs
Most of the supporting ISPs have a simple application to enroll in their feedback loops. While they may vary slightly, most enrollment forms can be found on the ISP's postmaster page.
Point your reports to 250ok
Supporting ISPs most commonly send Abuse Reporting Format (ARF) files directly to an email address of your choosing. In this case, you can use 250ok's dedicated mailboxes for report collection.
