Source: https://developer.nylas.com/docs/new/release-notes/2023-04-18-message-tracking-changes/

Nylas updated the tracking URLs you use for the Nylas Email API link tracking feature. These updates apply to both the US and EU datacenters.

## What changed?

- The `t.nylas.com` URL for the US datacenter has been replaced with `usw2.nyl.as`
- The `euw1.t.nylas.com` URL for the EU datacenter has been replaced with `euw1.nyl.as`

## Why did we make these changes?

We made these updates to ensure that link tracking continues to work seamlessly for all of our users, and to improve the performance and reliability of the link tracking feature.
