As a Gmail user, you would have encountered the ‘Gmail Outbox Queued’ messages at some point. But did you ever wonder, what does this message mean? Why does Gmail mark your email as queued and keep it in the outbox?

There are a variety of reasons for that, and today we are going to explore them in detail. This write-up will explore what does queued mean in Gmail, and how to solve this Gmail issue. 

What Does Queued Mean in Gmail?

Queued issue in Gmail

Queued in Gmail means that the email you are trying to send is stuck in the outbox

So, what happens is that when you compose an email and send it, the email goes through your outbox and waits to be processed. However, when the messages are not able to proceed further, Gmail marks them as ‘Queued’.

There could be a variety of reasons for this error, such as an unstable internet connection and low storage space. The issue could be on your end or the service provider’s end. We will discuss these issues in detail in the section below. 

In a typical situation, the issue gets resolved after waiting a while. However, if the error doesn’t go away even after waiting, it’s time you start worrying about the emails.  

Note: Queued emails mainly affect Android users. 

Why Does My Email Say Queued?

There are a variety of reasons as to why your email says it is queued. It could be a poor connection or a device issue. To ensure the messages are sent, you must find the root cause and fix it.

Here is a list of reasons that could be responsible for Gmail queued in outbox

  1. Connectivity and Server Issues

    To send emails, you must have a stable Internet connection. So, if you have an unstable connection, your messages are bound to end up on the queued list. Moreover, you need to make sure that the server you are using is responsive, as downtime on the server also leads to queued emails. 

  1. Software Glitches

    As we move toward modern technology, instances of glitches and errors are becoming more common. These glitches also cause delays in sending out urgent messages.

  1. Reached the Threshold Limit

    Gmail has set some limits for sending out emails. Those limits state that you can’t address more than 500 recipients in a single email, or send & receive more than 500 emails in one day

    If you see the “You have reached a limit for sending mail” error, it means that you have reached the threshold limit and cannot send emails within 24 hours.

  1. Low Storage Space

    If your device is low on storage and you are trying to send large files, you might face some problems. Check the internal storage and find out if your device is overloaded with unnecessary data.

  1. Recipient Mailbox Status

    The problem may lie on the recipient’s end. If their mailbox is low on storage, then your email might be marked as queued in Gmail. 

  1. Service Provider’s Protocols

    Often, the protocols set by providers prove to be the reason for unsuccessful email delivery. These protocols treat your email as a threat to the receivers and unintentionally block it. 

  1. Content Filter

    The outgoing spam filter is a feature that blocks emails that might pose a threat to the receiver. This feature can also cause your emails to be flagged and marked as queued.

  1. Authentication Issues

    SMTP (Simple Mail Transfer Protocol) authentication issues that arise due to incorrect settings or outdated apps stop emails from being sent.

We will address these issues in the succeeding section. So, stay with us and find out the suitable fix.
