Android 11; Samsung Galaxy A20; Gmail app (fully updated):

When I send an email that has an image, the email gets stuck in the Gmail outbox folder (status = Queued) for a day or two before eventually being sent.


  1. This issue started a couple of weeks ago. The Gmail app worked fine before then -- ever since I got the phone years ago. I'm not aware of any changes that were made to my phone/settings that might have caused this issue.
  2. The issue happens no matter what the file size is -- not just for large photos. For example, a screenshot of a small area of the screen also has this issue.
  3. The network type is a cell data plan, not Wi-Fi. Although switching to Wi-Fi doesn't solve the issue either.
  4. I tried resetting the Gmail app by un-updating the app (can't uninstall the app), then re-updating the app. That had no effect. I also cleared the app cache and data.
  5. The issue happens regardless of the email recipient.
  6. I don't have this problem when sending emails that have no attachments.

Why are emails with attachments not being sent right away?

  • GMail app allows to use GMail as well as IMAP accounts from other mail servers. What mail account is your question about?

  • @Robert It’s a Gmail account. I.e. [email protected].

I don't have an answer as to why it's happening. But I did come up with a couple of workarounds:

  1. Sometimes works: Refresh the outbox folder in Gmail by using the drag-down motion.

  2. Always works: Send the email from the Gmail website in a browser instead of using the Gmail app.


This might be a rare use case but it has caused me stuck emails: opening a Zip file with images, viewing an image, and sharing that image in Gmail in the image viewer.

It might be because the image is unzipped to a temporary file which is not available for Gmail to attach.

The remedy is to unzip the file into a folder before sharing it.
