Delay Sending All Outgoing Emails by Seconds in Outlook

Author: Sun Last Modified: 2024-06-20

Sometimes, in Outlook, you may immediately regret sending an email after clicking "Send." Perhaps you noticed an error in the email content or realized you forgot to attach a file. At this point, stopping the email from sending is usually not possible. Now, Kutools for Outlook offers a feature that can help: Delayed Email. When you enable this feature, all your sent emails will be delayed by 5-60 seconds (a duration you set). During this time, you can review the email, choose to stop the send, or opt to send it immediately.

Applications of the Delay Email Feature


In many scenarios, the Delay Email feature in Outlook proves to be invaluable. Hereโ€™s why itโ€™s essential and how you can use it effectively:

Avoiding Errors

Often, you might realize an error in your email or forget to attach a file right after clicking "Send." The Delay Email feature gives you extra time to review and correct any mistakes, ensuring your email is accurate and complete.


When your recipients are in different time zones, scheduling your email to be sent during their working hours increases the likelihood of it being read and responded to promptly. The Delay Email feature allows you to manage this seamlessly.

Cooling Off

Dealing with sensitive or emotional topics can sometimes lead to impulsive emailing. By delaying your emails, you have time to reassess your message and ensure it maintains a professional and courteous tone.

Preventing Overwhelm

The Delay Email feature helps stagger the send times if you need to send multiple emails. This prevents your recipients from being bombarded with several emails at once, enhancing their overall reading experience.
