How to Mark an Outgoing Email as Urgent in Gmail

Gmail has no built-in flag for marking outgoing emails as urgent. The workaround is to include a priority keyword at the start of the subject line.

Use prefixes like URGENT, IMPORTANT, ACTION REQUIRED, CRITICAL, or DEADLINE [date] to signal urgency and make the email stand out in the recipient inbox.

When the Important Label Is the Right Tool

Use the Important label to flag emails that need action or follow-up, especially in a busy inbox with newsletters and automated messages mixed in.

For outgoing messages, subject-line keywords work better than any label since labels are a receiver-side feature that the sender cannot control.
