If we find your ESP eligible, we will get back to you with the spec and implementation requirements/details, over the next few weeks. Since slots are limited, we will not be able to accommodate everyone, but will do our best. Conformance to Gmail's Bulk sender guidelines (https://support.google.com/mail/answer/81126?hl=en) will be considered as the primary eligibility criterion.
Please register only once.
Note: At this time, we are only piloting ESPs and NOT any other senders.
