[Email_Status] returns the status of an email message that was sent using [Email_Send] or [Email_Queue]. The tag requires the unique ID of the email message which is returned using [Email_Result].

The tag will return a value of "queued", "error", or "sent". Lasso attempts to send messages multiple times if minor errors are encountered. A valid message will have a status of "queued" until the maximum number of retries is reached. Messages which are invalid or have reached their retry limit will have a status of "error". Messages which have been sent (or are not found in the queue) will have a status of "sent".

Note that [Email_Status] called immediately after queueing a message will almost always return "queued" since Lasso has not yet had a chance to send the message. It can take a few seconds on an idle server to send a message or longer on a busy server. This tag would typically be used by storing the unique ID returned by [Email_Result] in a database and then checking on the status of the message after a suitable delay.
