   THIS IS A SCHEDULED EVENT Jun 15, 10:00 - 13:00 UTC Jan 27, 16:16 UTC Scheduled - As Optimove works to strengthen security and align with industry best practices, Optimove is changing how SFTP connections are configured. What is changing Effective June 15, 2026, all SFTP connections to Optimove must be restricted to one or more specific source IP addresses or IP ranges. Connectivity to Optimove's SFTP from IPs which haven't been whitelisted will no longer be supported. Action required To ensure uninterrupted service, please email [email protected] with the following details so we can configure IP allowlist for your SFTP connection: 1. SFTP username used to connect to Optimove 2. Either: * Your source public IP address(es) used for the connection (static egress IPs), or * Your IP range(s) (CIDR notation accepted, for example 203.0.113.0/24) Important If you use multiple usernames or multiple egress IPs/ranges, please include all relevant details. Once this change is applied, only the IP addresses or ranges you provide will be permitted to access Optimove’s SFTP. Please ensure the information you share is complete and accurate. Impact if not completed After June 15, 2026, SFTP connections that are not restricted to approved IPs may be blocked, which can interrupt file transfers. Need help? If you are unsure which public egress IP or range to provide, your IT or infrastructure team should be able to confirm it. Our support team can also help validate formatting.
