The Email History will show any of the following in the Status column:
In Progress - preparing to send.
Scheduled - is ready to send according the schedule in the Email Sequence.
Delivered - the email has been accepted at the receiving server.
Deferred - when an email cannot immediately be delivered, but it hasn’t been completely rejected. SendGrid will continue to try for 72 hours to deliver a deferred message. After 72 hours, the deferral turns into a block.
Opened - this shows the last time the customer opened the email.
Dropped - when the email has not been sent for delivery. This may be because the email contains spam content or if the recipient has unsubscribed previously.
Bounced - failed to deliver or blocked by the receiving server, as the email address is not authenticated. Contact us here if this happens and we can investigate.
Cancelled - a scheduled email has been cancelled due to a Refund or Exchange.
