When an email is "queued," it means the email is waiting in a queue on the email server or in your email client because it cannot be sent immediately. This situation usually happens due to issues such as temporary internet connectivity problems, server delays, or other technical glitches preventing the immediate delivery of the email. The email remains in this queued state until the issue preventing its sending is resolved, at which point the email will be sent automatically. Common reasons for emails being queued include weak or disrupted internet connection, server overload or unavailability, sending limits imposed by the email provider, large attachment sizes exceeding limits, software glitches, or authentication issues. Queued emails are essentially in a temporary holding pattern, allowing email servers to manage delivery efficiently without losing messages.

In short, "queued" means the email is lined up and waiting to be sent as soon as sending conditions are favorable or the problem is fixed.
