ReturnPath
History Return Path was a major driver for the establishment of Feedback Loops (FBLs) back in the mid to late 2000s. They worked with a number of ISPs to help them set up FBLs and managed the signup and validation step for them. In return for providing this service to senders and receivers, they used this data as part of their certification process and their deliverability consulting. Return Path had a strong corporate ethos of improving the overall email ecosystem that originated from the CEO and permeated through the whole organization. In 2019 Validity acquired Return Path and within two months closed two offices and laid off more than 170 employees, many who are industry leaders and long time colleagues. In 2020 Validity acquired 250OK, one of their major competitors. Over the next year they then ended long term agreements with ESP partners, sued competitors and significantly raised prices for
