250OK does almost everything we are looking for and has a great support team, dedicated to not only providing answers but understanding, in our quest to learn more about email deliverability.Love the interface and UI. Streamlined and easily accessible. Customizable dashboards right up front. You can view the kind of granular data like what inbox are they using, what long/latitude, time of day, mobile vs desktop etc.

The employees / customer support. They're very responsive to feedback and seem to work hard to improve their products. The wide variety of features blends well in the interface, and "child accounts" let you securely distribute services to clients.

We are notified when senders are hitting spam traps and provided with the subject line of that email. We are able to then work with the sender directly to correct the problem.I like that 250ok gives us a way to monitor when spam traps are hit so that we can then deal with each customer directly to resolve the issue.

Deliverability is critical in a loud and crowded market. There are many points of vulnerability and 250ok will help you track, monitor, and fix whatever comes your way. Really enjoyed the service and deep dives with their consulting services. They give a wide range of options on how you want to engage. We dove in with a deep dive around our current status, then were able to engage on the platform to track key metrics. I love that I can re-engage in a project by project basis as needed in the future.
