About This Feature

Overview

Undo Send is an email sending safeguard in WPS Mail that lets you cancel a message shortly after sending it, helping reduce issues caused by accidental delivery, missing attachments, or content mistakes.

Core capabilities include:

Turn on Undo Send: Enable the feature in mail settings and choose a cancellation time limit.
Cancel a just-sent email: Click Undo while the prompt is still visible to move the message back to Drafts for editing.

This feature is useful for final checks before formal email delivery, attachment corrections, recipient fixes, and last-minute content updates.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	You can turn on Undo Send in mail settings, choose a 5-second, 10-second, or 30-second cancellation window, and click Undo after sending to return the message to Drafts.	Outlook officially supports delayed or scheduled sending. In new Outlook, users can use Schedule send; in classic Outlook, delivery can be delayed before the message leaves the Outbox.	Gmail officially supports unsending a message after sending and lets users choose a 5-second, 10-second, 20-second, or 30-second cancellation period.	Notion Mail provides an official Undo shortcut for message actions, but its public help content is centered more on shortcuts and mail operations, and Notion has announced the product shutdown timeline.	Adobe Acrobat Sign provides adjacent workflow control such as canceling an in-progress agreement, but it does not provide a direct email undo-send feature that matches WPS Mail.
WPS Advantages	Advantage: The setting is grouped under sending settings, and after cancellation the email returns to Drafts for immediate editing and resend.	Compared with WPS: Outlook public guidance on Windows focuses more on delayed or scheduled delivery than on a post-send prompt that returns the message to Drafts in the same way.	Compared with WPS: Gmail also supports post-send cancellation, but it offers more time options than WPS.	Compared with WPS: Notion Mail public guidance is more shortcut-oriented, and the product lifecycle is limited by its announced shutdown.	Compared with WPS: Adobe’s official capability is closer to document workflow cancellation than email send cancellation.

Overall Conclusion
WPS Undo Send works well for users who want a short correction window immediately after sending an email. Its setup path is straightforward, and the canceled message returns to Drafts for quick revision. If you need more cancellation time choices, Gmail offers more options, while Outlook and Adobe focus more on their own delivery management or workflow control models.
