Sketch review
If I’m asking an editor to check a new mobile layout, I want them to open the page we’re discussing. Sketch can share a preview of selected pages or prototypes from a Workspace document. The editor can open the preview in a browser without having a Sketch account.
Send the page you want feedback on
Open the document in the web app, then choose “Share” and “Create a Preview”. Name it for the page or decision you want reviewed and select what to include. If you add a prototype, Sketch includes the page that contains its frames. I’d give the prototype a page of its own if I wanted to keep nearby rough ideas out of the review.
Keep control of the same link
An editor or admin can set a password or an expiry date before copying the link. The preview shows the latest version of the selected work. If I change a button label after receiving feedback, the updated label appears at the same address. When I need a dated copy of what we agreed, I’d keep a separate PDF and annotate it in PDF Expert.
Anabel’s take
I’d send one preview with a short question about what to check. Once we agree on the layout, I’d save the version we approved and remove the preview if nobody needs the link anymore.
