Scheduled Maintenance
Sending Domains API - USA Dec 13, 2022 19:00-21:00 EST
Update - We will be undergoing scheduled maintenance during this time.
Nov 17, 2022 - 08:48 EST
Update - We will be undergoing scheduled maintenance during this time.
Nov 17, 2022 - 08:44 EST
Scheduled - Update: date changed to 13 December. At 19:00 EST on December 13th, SparkPost will be conducting maintenance in our US-West region to apply a critical update. During this maintenance period (up to 2 hours), the Sending Domains API will be unavailable - customers will not be able to list, create, edit or delete sending domains - and will return a 5xx response code. (Please retry calls to the Sending Domains API that are not successful.)

Message injection (Transmissions API or SMTP API) and outbound message delivery will be unaffected as long as the sending domain specified in the email has been used in the past 24 hours (the service will rely on a cache). Injections will fail if the message is using a sending domain that has not been used recently or is brand new.
