As a working professional, sending emails is very common, and it happens to most of us that after sending a message, we instantly realize that something is wrong with the message. It might be a typo, an attachment missing, or an email sent to the wrong person. Most users search for reliable ways to unsend emails in Thunderbird. It doesn’t offer an inbuilt feature like Outlook.

In this article, we will walk through smart workarounds to prevent email errors. Before that, we will understand the unsend concept. I will also suggest tools like SysTools MBOX to PST Converter if you consider converting your data for backup or migration.

Understanding the Concept of Recalling an Email in Thunderbird 

Thunderbird does not have an option to recall an email. However, you can still avoid mistakes using default features and simple strategies

Before exploring alternatives, here’s what you can expect when learning how to recall an email in Thunderbird.

Use the “Undo Send” Feature to Unsend Email in Thunderbird

Thunderbird has a basic Undo Send option via delayed delivery. But this feature doesn’t recall a sent email; it prevents you from leaving your Outbox immediately.

Steps for using Undo Send:

• Open Thunderbird 

• Go to Menu > Preferences > Composition 

• Enable “Delay message sending by X seconds. “

• Set a delay, usually 5-30 seconds.

• Your email remains in the Outbox until the timer ends.

This feature allows you to unsend email in Thunderbird before it actually gets delivered to the recipient.

Manually Stop an Outgoing Message Before It Leaves

If Thunderbird is still trying to send a big email, you can stop it yourself.

How you can do it:

• After clicking Send, quickly go to the Activity Manager

• If the message is still in the sending process, click Stop

• Open the Outbox to correct your email.

This method can help you when you want to fix issues related to how to recall an email in Thunderbird before it is sent out.

Enable Send Later Command as an Email Safety Net

You can use the Send Later feature, as it will give you some extra time to review the email, instead of sending emails instantly.

Steps:

• Write the email as usual

• Press Ctrl + Shift + Enter or choose File > Send Later.

• Thunderbird stores the email in your Outbox.

• Send manually after reviewing

This gives you the upper hand if you want to unsend email in Thunderbird due to mistakes.

Use Add-ons to Enhance Recall-Like Behavior

Some built-in extensions offer scheduled sending or additional delay settings. They can’t help you recall an email, but they will help you with better control

Here are some helpful Add-ons:

• Send later (advanced version)

• Message Timer delay

These tools are very useful variants when exploring how to recall an email in Thunderbird without any support.

Best Practices to Avoid Email Mistakes in Thunderbird 

Using these tips can help you minimize the need for recall attempts:

• Always check twice the recipient list before sending an email

• You can enable delayed sending for all the emails

• Use templates while sending repetitive emails. 

• Always verify the attachments before sending emails

• Keep drafts and send only after reviewing

These are some good habits that reduce the chances of needing to unsend email in Thunderbird or fix errors after sending.

Convert Thunderbird Emails Safely (Recommended for Professionals)

If you manage large Thunderbird mailboxes, migrating or converting data becomes important.

For better compatibility with Outlook or for secure backup, the SysTools Thunderbird Converter allows users to convert Thunderbird emails into multiple formats like PST, EML, PDF, and more. This tool makes sure that your data remains organized while focusing on understanding how to recall an email in Thunderbird and improving your email productivity.

As we know that the Thunderbird doesn’t have it built-in recall feature that other email clients offer, like Outlook.
