About This Feature

Overview

Undo Send is a built-in send-control feature in WPS Mail on macOS. It lets you cancel a message within a short period after sending, which helps reduce mistakes such as sending to the wrong recipient, forgetting an attachment, or sending unfinished content.

Core capabilities include:

Turn on Undo Send: Enable the feature in send settings and choose a cancellation time.
Cancel a just-sent email: Click Undo while the prompt bar is visible and return the message to Drafts for editing.

Common use cases include daily work email, final review before external communication, attachment checks, and quick content corrections.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Supports canceling a sent email within a short time by clicking Undo, with 5-second, 10-second, or 30-second options in settings.	Outlook for Mac supports Undo Send by delaying message delivery. It supports 5, 10, 15, and up to 120 seconds, but it requires the new Outlook for Mac and a Microsoft 365 subscription license.	Gmail supports unsending a message right after sending, with a send cancellation period of 5, 10, 20, or 30 seconds.	Official Notion Mail pages show send, drafts, and an Undo shortcut, but they do not clearly document a dedicated post-send undo window.	Adobe Acrobat Sign supports canceling an in-progress agreement, not a short post-send email undo workflow.
WPS Advantages	Advantage: The setting is available directly in WPS Mail on macOS, with 5-second, 10-second, and 30-second options, and a successful undo returns the message to Drafts for editing.	Compared with WPS: It offers a longer delay range, but availability depends on the new Outlook for Mac, supported account types, and subscription licensing.	Compared with WPS: It also provides a short undo-send window, with official guidance for browser and app use.	Compared with WPS: Public help content focuses more on shortcuts and inbox actions, and the post-send undo window is not clearly documented.	Compared with WPS: Its workflow is centered on e-signature agreement management rather than standard email send cancellation.

Overall Conclusion
For users who want a quick correction window after sending email, WPS Undo Send provides a direct setup path and clear feedback on macOS. Compared with common mail products, it fits users who want to review and revise messages quickly inside the mail workflow, while Adobe’s comparable action is aimed at agreement management rather than standard email undo.
