We receive an email dated yesterday, but at what exact time was it sent? This question often arises when we need to prove a timely dispatch, check a time zone difference with a foreign correspondent, or simply understand why a message arrived late. Retrieving the sending time of an email does not require technical skills, but the method varies depending on the email client and the type of device used.
Why the time displayed in your inbox can be misleading
When a colleague claims to have sent their email at 5 PM and you only see it at 11 PM in your inbox, the instinct is to doubt. The explanation often lies in how your email client presents the information.

Gmail, for example, only displays the date without the time for messages received before the current day. You need to hover over the date with your mouse cursor for a tooltip to reveal the full timestamp. On mobile, this hover trick does not exist: you have to open the message to access the details.
The display can also be misleading in conversation threads. Recent Gmail interfaces sometimes hide the actual sending time of an individual message in favor of the date of the first or last message in the thread. You think you are checking the time of your own sent message, while you are actually reading the time of a previous reply. Before searching further, it is worth consulting Astuces Business to find out the sending time of an email and understand the display nuances specific to each service.

Sending time in Gmail and Outlook: accessing details on computer and mobile
Gmail on web browser
In the message list, the right column displays the time for today’s emails and the date for older emails. Hovering over the date with the mouse reveals the exact time without opening the message. This is the quickest method for daily use.
When opening the email, you can find the date and time at the top right, next to the sender’s name. For messages grouped in a conversation, you need to expand each reply individually: the timestamp displayed in compact mode sometimes corresponds to the overall thread.
Gmail on mobile (iOS and Android)
The app displays the time on the right for today’s messages. For an older message, only the date is visible in the list. You must open the email and then look for the date line under the sender’s name. No hover function exists on a touchscreen.
Outlook on desktop
On the Outlook desktop app (Windows or Mac), the message list shows the time for the current week and the date beyond that. To find the time of an older message, you can:
- Open the message and read the “Sent:” or “Received:” line in the email header
- Switch to “List” or “Compact” view and add the “Received” column (right-click on the column header, then “Choose columns”)
- Hover over the message in the reading pane to see the full timestamp in some recent versions
Outlook.com and mobile app
On the web version, a click on the message is enough to display the full date and time in the reading pane. On the mobile app, the time appears directly when opening the email, below the subject line.
Email headers: finding the technical timestamp when the display is insufficient
The reading interface gives the time as interpreted by the email client. But the full headers of an email contain several technical timestamps that tell a different, more precise story.
Each server the message passes through adds a “Received:” line with its own timestamp. The “Date:” field corresponds to the timestamp set by the sender’s client at the time of submission. By comparing these different lines, you can spot a time zone difference or a delivery delay between servers.
To access this, the manipulation depends on the service:
- Gmail: open the message, click on the three vertical dots on the right, then “Show original”
- Outlook.com: open the message, click on the three dots, then “View message source”
- Proton Mail: open the message, click on “More”, then “View headers”
- Apple Mail: Presentation menu, then “Message”, then “All headers”
You will get a block of plain text. The “Date:” field indicates the time declared by the sender, while the “Received:” lines are read from bottom to top (the oldest being at the bottom). The difference between the first “Received:” line and the last gives the transit time of the message through the servers.
Difference between sending time and receiving time of an email
A point often misunderstood: no email client retains the exact moment when the user clicks “Send”. What is recorded is the time at which the sender’s server takes charge of the message. If the local network was slow or if the client was operating in offline mode, there can be a delay of several minutes (or more) between the click and the actual processing.
The receiving time corresponds to the moment when the recipient’s server accepts the message. In between, each intermediate relay adds transit time. In most exchanges between modern servers, this delay remains negligible. But in cases involving security gateways, anti-spam filters, or overloaded servers, the returns vary on this point, and delays of several minutes are not uncommon.
For everyday use (to check that you replied before a deadline, for example), the time displayed in the opened message is sufficient. When precision really matters (dispute, proof of prior existence), the technical headers remain the only reliable source to reconstruct the complete path of the email.
The reflex to keep: if the time displayed in the message list seems inconsistent, open the email. If doubt persists, check the headers. The answer is always there, as long as you know how to read the “Received:” lines in the correct order.
