Today, we're releasing an update to Send Time Optimization, and we're removing API support for TLS 1.0 and 1.1.
iOS 15 and Send Time Optimization
With this release, we've tuned Send Time Optimization to account for Mail Privacy Protection, a feature added to Apple Mail in iOS 15.
Disabling API support for TLS 1.0 and 1.1
As announced on September 22, 2021, today we're disabling our API support for calls that rely on Transport Layer Security (TLS) 1.0 and 1.1. Calls made to Iterable's API must now support TLS 1.2. Otherwise, they will fail.
For more information about this change, see our release notes from September 22, 2021.
