Between Thursday, April 12th and Monday, April 16th, Coinbase experienced an issue with the delivery of confirmation emails for instant purchases. Customers who successfully completed an instant purchase during this period may not have received an email confirmation for their purchase. We apologize for any inconvenience this may have caused.
We have identified the customers impacted by this issue and will be re-sending the previously undelivered confirmation emails. Customers' transactions were not affected by this issue.
