Gmail Read Receipt Request: How to Decline or Turn Off

If a Gmail read receipt request just appeared on an email you opened, the short version is this: clicking Not now sends nothing, the sender is not told you declined, and the sender cannot find out whether you opened the message through that prompt. Only Google Workspace accounts (work or school) ever see these prompts; personal @gmail.com accounts ignore read receipt requests silently. Workspace admins can switch receipts off for everyone in the Admin console. The one thing a read receipt setting does not control is open tracking by invisible images, which is a separate mechanism and needs a separate fix: tell Gmail to ask before displaying external images.

The rest of this article walks through each of those situations, because people searching for "gmail read receipt" at this point usually mean one of three different things: how to decline a request, how to stop being asked at all, or how to stop a sender from knowing they opened an email.

What a Gmail read receipt request actually is

A read receipt is an old email standard. The sender's mail program adds a header to the message that says, in effect, "please notify this address when the message is displayed." When the recipient's mail program sees that header, it can either ignore it, ask the recipient, or send a tiny automatic email back to the sender saying the message was read, with a timestamp.

In Gmail the two sides of this look like:

  • Google Workspace accounts (an address at your company or school that runs on Gmail) can request read receipts when composing, if the admin allows it, and can see requests when receiving. That is where the "The sender has requested a read receipt" banner comes from.
  • Personal Gmail accounts (@gmail.com) cannot request read receipts, and when they receive an email with a request attached they show nothing. The header is simply dropped. If you only use a personal account and are seeing a prompt, it is almost certainly coming from a different mail client, such as Outlook, not from Gmail.

Two things are worth knowing before you decide what to click. First, the receipt is a real email, sent from your address to the sender, so it is not anonymous. Second, it is one-way: once you send it, you cannot recall it.

Decline a Gmail read receipt request without sending anything

When a Workspace account opens a message that carries a request, Gmail shows a small notice near the top or bottom of the message with two choices, Send receipts and Not now.

  1. Read the message as normal. Opening it does not send a receipt by itself when the prompt is showing; only the button does.
  2. Click Not now. No email goes back to the sender. There is no "declined" notification on their side; from their point of view it looks exactly the same as if you had never opened the message.
  3. Expect the prompt to come back. Gmail may ask again the next time you open the same conversation, because the request is attached to the message, not to your answer. Clicking Not now again is fine; it still sends nothing.
  4. If you later decide the sender genuinely needs confirmation, you can open the message and click Send receipts at that point. The timestamp on the receipt will reflect when you clicked, not when you first opened the email.

One case to be aware of: your admin can configure Gmail to send receipts automatically, without prompting, for senders inside your organization or on an approved list. If you never see a prompt but colleagues say they receive receipts from you, that setting is the reason, and the next section explains where it lives.

Turn off Gmail read receipts for your organization

Individual Workspace users do not have a personal on/off switch for read receipts in Gmail settings. The control is at the admin level, which means you either are the admin (common in small businesses) or need to ask whoever manages your Google Workspace.

For the admin:

  1. Go to the Google Admin console at admin.google.com and sign in with an administrator account.
  2. Open Apps, then Google Workspace, then Gmail.
  3. Click User settings.
  4. If you want different rules for different teams, select the organizational unit on the left first. Otherwise leave the top-level organization selected.
  5. Find Email read receipts. You will see three options:
    • Do not allow email read receipts to be sent. This removes the request option from the compose window and stops Gmail from responding to incoming requests. Nobody in that organizational unit will see the prompt again.
    • Allow email read receipts to be sent to all addresses in my organization as well as the whitelisted email addresses. Receipts work internally and with any addresses you list. Below this option there is a checkbox, Prompt the user for each read receipt request; leave it ticked if you want people to choose each time, untick it if you want receipts sent automatically to those addresses.
    • Allow email read receipts to be sent to any email address. The most permissive setting; users are prompted for every request, including from outside senders.
  6. Click Save. Changes usually take effect within a short while, though Google notes they can take longer to reach every user.

If you are not the admin, a short message along the lines of "Could you set Email read receipts to Do not allow for our team?" is all they need; the path above tells them where to click.

Stop email open tracking too: the other kind of read receipt

This is the part most people miss. Turning read receipts off stops the polite, visible request. It does nothing about email open tracking, which works without asking you at all.

Open tracking is done by placing a tiny, usually invisible image in the email, hosted on the sender's or a tracking service's server. When your mail program loads that image, the server records the time, and the sender's tool marks the message as opened. Newsletters, sales teams and many ordinary Gmail users with a tracking extension installed rely on this. There is no prompt and no "Not now" button because you are never asked.

What stops it is not loading remote images until you choose to.

On Gmail in a browser

  1. Click the gear icon at the top right and choose See all settings.
  2. Stay on the General tab and scroll to Images.
  3. Select Ask before displaying external images.
  4. Scroll to the bottom and click Save Changes.

From now on, emails with remote images show a bar at the top reading Images are not displayed with a Display images below link. Tracking pixels only fire if you click that link. Plain text emails and emails from people who do not use tracking look exactly as before.

In the Gmail app on Android and iPhone

  1. Open the Gmail app, tap the menu (three lines) and scroll to Settings.
  2. Tap the account you want to change.
  3. Tap Images and choose Ask before displaying external images.

Repeat for each account if you have more than one signed in.

What this does and does not protect

  • Gmail already fetches images through Google's own servers, so even with images set to always display, a tracker normally sees Google's proxy rather than your home or office location. The "ask first" setting goes a step further by not fetching at all until you say so.
  • Browser extensions exist that detect and flag known tracking pixels in Gmail; they can be a useful extra layer, but Gmail's own image setting already stops the pixel from loading, so it is the first thing to change.
  • If you also read mail in Apple Mail with Mail Privacy Protection on, be aware that it does the opposite: it preloads images on Apple's servers, so senders may see an "open" even for emails you never looked at. That is a quirk of Apple's approach rather than something you can fix in Gmail.
  • Blocking images is not a way to hide that you replied. Once you answer, the sender obviously knows the message reached you.

If you are the sender: what you can realistically get back

The same facts apply in reverse if you are the one hoping for a confirmation.

A Gmail read receipt only works when you are on Workspace, your admin allows it, and the recipient's mail client both supports receipts and chooses to send one. Personal Gmail recipients will never respond; Workspace recipients can click Not now; many other mail programs ignore the header. If you are sending from a personal @gmail.com account the option does not exist in the compose window at all. Open tracking is the alternative most people end up using, and it is worth being clear about what it can and cannot tell you.

A tracking tool such as Zestmail for Gmail adds open tracking directly in Gmail: after you send, it shows whether and when the recipient opened the message, and it filters out your own opens and common bot opens so a security scanner or your own re-read of the sent mail is not counted. It works from a personal Gmail account as well as Workspace, which is the main practical difference from read receipts. The free plan covers up to 20 emails a day and adds a small "Sent with Zestmail" footer to those emails; Pro removes the footer and is $9 a month or $69 a year with a 7-day free trial, as listed on the pricing page. The extension does not ask for permission to read your inbox.

What no tracking tool can promise is certainty. Everything in the previous section applies to your recipients too: someone who has set Gmail to ask before displaying external images, or whose company blocks remote images, will read your email and show as not opened. Someone on Apple Mail with privacy protection may show as opened without having read it. Treat an "opened" as a strong hint rather than proof, and treat "not opened" as "no signal yet" rather than "ignored." If a message truly needs confirmation, the reliable method has not changed: ask for a one-line reply, or follow up by phone.
