When clicking inline email anchors, the viewport does not change to the ID/target of the link.
An example would be found in HARO emails - where a digest of links directs the reader to content found farther down in the email body.
Let email anchors function similar to the web.
Scrolling down many pages worth of content to the destination.
This is a typical UX pattern while browsing the web. Lengthy emails often direct readers to content within the email. This merely gets up to parity of normal web browsing behavior.
In the screenshot below, here’s an example email containing internal anchors. When clicked, the viewport moves to it. The email client is Gmail.
