Optimize your email program with advanced analytics for deliverability, recipient engagement, address validation, design testing, and DMARC.
250ok is a leader in advanced email analytics and deliverability. We drive insights about inbox performance, sender reputation, fraud protection (DMARC), design rendering, and consumer engagement. Best-in-class marketers use 250ok hand-in-hand with their email service provider (ESP) to maximize email performance. Most of the largest ESPs use 250ok to power their own solution (Adobe, Marketo, SendGrid, SparkPost). 250ok is the viable alternative to Return Path.
250ok was acquired by Validity in March 2020 and is not currently available for sale. We’ve teamed up with Return Path and have been hard at work creating something without equal in the email world. It’s been an amazing journey and we’re proud to announce Everest, the only truly end-to-end solution available–helping you succeed in all three critical phases of email marketing: pre-flight prep, in-flight optimization, and post-send monitoring.
