Unfortunately per [Linkable Mac Applications](https://hookproductivity.com/what-mac-apps-are-compatible-with-hook-app)

The following three email apps are supported but we cannot recommend them because the email IDs or URLs they expose are **not** compliant with [RFC 5322 – Internet Message Format](https://tools.ietf.org/html/rfc5322#section-3.6.4). This means the links cannot be shared with others and are not guaranteed to work on different Macs – even of the same user.

> - 🤔 [Spark by Readdle](https://sparkmailapp.com/) ([Forum topic](https://discourse.hookproductivity.com/t/hook-spark-email-integration/2239/13). This uses Spark’s email links, which do not seem to work across devices.)

which is why we cannot recommend those apps.

I’m connected to a Microsoft VIP who, on our behalf, will request of Microsoft that they expose RFC-5322 compliant email ID’s in their automation.
