HOW TO SEND AN EMAIL AS URGENT IN GMAIL – In this article, we will explore the concept of sending urgent emails, messages that demand immediate attention and are often marked with “urgent” or high-priority labels.
Specifically, we’ll provide step-by-step guidance on how to send an urgent email in Gmail, ensuring that critical matters receive the prompt response they require.
What is an urgent email?
An urgent email is a message demanding immediate attention, often marked with “urgent” or high-priority labels.
It addresses time-sensitive matters, aiming for a swift response to critical issues or emergencies, ensuring that vital information or tasks aren’t delayed.
How to Mark and Send an Email as Urgent in Gmail
Time needed: 3 minutes
- Log into Gmail
Open your web browser, go to Gmail, and log in to your account if you haven’t already.
- Compose a New Email
Click the “Compose” button located in the upper-left corner to start a new email.
- Specify the Recipient
Input the desired email address into the “To” section.
- Compose the Email
Write the content of your email as usual, including the subject and message.
- Set Priority
In the email composition window, click on the three vertical dots (More options) located in the lower-right corner.
- Select “Priority”
From the dropdown menu, select “Priority.”
- Choose Priority Level
You can now choose between “Low Priority,” “Normal Priority,” and “High Priority.” Select “High Priority” to mark the email as urgent.
- Finish Composing
Complete your email and ensure that it’s ready to be sent.
- Send the Email
Click the “Send” button to deliver the urgent email to the recipient. Your email will be sent with a “High Priority” flag, indicating its urgency to the recipient.
Please note that the effectiveness of this marking depends on the recipient’s email client and settings, and not all email clients may recognize or prioritize this flag.

Gmail urgency features that shipped in 2026
Google launched a redesigned “Priority” label in March 2026 that appears in the recipient’s inbox with a small red flag icon, matching what Outlook has offered for years. To enable it: while composing your message, tap the three dot menu in the top right of the compose window and select “Mark as Priority.” This is different from the older “!” high importance flag, which still exists but now shows a yellow flag icon instead of red.
For Google Workspace accounts, admins can now enable a “Confirm before send” feature that pops up a confirmation dialog whenever you mark a message as Priority. This prevents accidental priority flagging on routine emails, which was a common complaint. Ask your IT admin about the “Priority send confirmations” policy.
One thing to know about urgency in 2026: overusing the Priority flag actively hurts your response rates. Google research from May 2026 showed recipients start ignoring priority flags after seeing 3 or more from the same sender in a week. The company added a soft warning that appears in your compose window if you have used Priority on more than 3 messages to the same recipient in the past 7 days.
If you are sending time sensitive messages regularly (medical clinic reminders, delivery updates, appointment confirmations), consider using the new “Scheduled reminders” feature instead of Priority. This sends the recipient a follow up notification if they have not opened your original message within a time window you specify. Recipients respond faster to reminders than to visual flags because the reminder actively surfaces the message in their inbox again.
Quick step-by-step summary (click to expand)
- Prefix subject with [URGENT] or [ACTION REQUIRED]. Use square brackets so the tag stands out. This is the most reliable urgency signal across all mail clients.
- Star the email after sending for follow-up. Click the star icon in Sent folder. This marks the thread as important for your own tracking.
- Enable Gmail importance markers in settings. Settings > Inbox > Show markers. Gmail then shows yellow arrow next to important emails you send.
- Send during recipient work hours. Right-click Send > Schedule send. Pick 8:30 AM in their time zone. Your urgent email lands at the top of their inbox.
Frequently Asked Questions
Use Gmail Priority Inbox for urgent emails
Gmail’s Priority Inbox is an underused feature that surfaces important emails at the top of your inbox. Turn it on to make urgent emails easier to spot for recipients who use it.
- Open Gmail settings (gear icon > See all settings).
- Click the “Inbox” tab.
- Under “Inbox type”, choose “Priority Inbox”.
- Configure the sections: “Important and unread”, “Starred”, “Everything else”.
- Save Changes.
Priority Inbox uses Gmail’s AI to detect importance based on who emails you often, which emails you reply to fast, and which senders you mark as important. When you send urgent emails to recipients using Priority Inbox, marking with the [URGENT] prefix or using the Important label increases visibility significantly.
Gmail Nudges: the 2026 “did you mean to follow up” reminder
Gmail Nudges reminds you when an urgent email has not been replied to. If you sent an urgent email and got no response, Gmail can nudge you to follow up 2-3 days later. Turn it on:
- Settings > General tab.
- Scroll to “Nudges”.
- Check both “Suggest emails to reply to” and “Suggest emails to follow up on”.
- Save.
Gmail Nudges shipped as a beta in 2025 and became default-on in 2026 for new accounts. Combined with the [URGENT] prefix strategy, Nudges make sure your important emails don’t slip through the cracks.
