Thank you for your patience while we are working on this issue.
We identified the root cause of the issue affecting our reputation score on Orange/Wanadoo, and we fixed it. We also took care to prevent any recurring situation.
All of our email deliveries are now back on Sendgrid, and we reached usual delivery performance.
RECOVERY:
We are currently targeting the dropped emails to resend them if they are still relevant (for example, we will not resend a "Delivery started" email if the package has been received by the shopper). This work is excepted to be finished during the day.
No action is required from the Merchants.
