Wairds,

Thanks so much for answering those questions for us.

Since it sounds like the issue only happens when sending a message using Bcc, can you let us know if you're using the steps on the following page to send a copy of the message using Bcc? Address and send email in Mail on iPad

Also, we noticed you are using an older version of iPadOS; the current version is 14.4. You may want to try updating iPadOS using the steps outlined here: Update your iPhone, iPad, or iPod touch Please be sure to check out the "Before you update" section of the previous link for the steps to back up your device prior to updating.

Thanks!

Wairds,

Hello Wairds,

We understand that you're seeing an error when you send an email to yourself, and we'd like to see how we can help.

To help us get a better understanding of the issue, we’d like to ask a few questions.

1. Which iPadOS version are you using? Find the software version on your iPhone, iPad, or iPod
2. Is this happening when using the Apple Mail app, or another email application?
3. What type of email account are you using? If you use multiple email accounts, does this happen with all of them, or only a certain account?

In the meantime, the information here may help: Write an email in Mail on iPad

Thanks!
