Updates to API IP Addresses

Effective June 17, 2021, Sailthru will relocate the IP addresses for api.sailthru.com.

Marketers, please relay this message to the engineering teams responsible for your Sailthru integration.

This change should not affect most customers. Some customers may have Sailthru’s IP addresses on an allow list, which means this change would require an update to those rules. The new IPs are outside the current range previously issued to customers who inquired about allow listing, thus this change would only affect customers using more restrictive rules.

Please contact Support for the specific addresses.

We are activating two maintenance windows ahead of the final change date. During these maintenance windows we will temporarily begin using the new IP address for api.sailthru.com. At the end of the maintenance window we will switch back to the current IP. These will serve as alert windows ahead of the change.

First Maintenance Window: June 3, 2021 Approximately 1 hour window of using the new IP address Second Maintenance Window June 10, 2021 Approximately 4-hour window of using the new IP address Final cut-over to new IP June 17, 2021

This change facilitates improvements to our load balancing and network infrastructure, part of our continued investment in you and your customers’ experiences.

Please contact Sailthru Support for any additional questions or concerns.
