You type out a reply, hit send, and only afterwards notice the sign-off is missing — no name, no title, no phone number, none of the neat little block you set up months ago. Or worse, a colleague forwards your email back and you can see the bottom is bare where your details should sit. When Gmail signature not showing is the problem, it feels like Gmail quietly ate your work, and on a busy day it looks unprofessional to everyone you email. The reassuring truth is that your signature almost certainly still exists exactly where you saved it — Gmail has simply not been told to attach it, or is attaching it somewhere you cannot see.
This guide walks the exact order a support engineer would use to get your sign-off back on every message, on desktop, Android and iPhone. You will learn why the single most common cause of Gmail signature not showing is a defaults setting that has nothing to do with the signature text itself, why your phone and your laptop keep two completely separate signatures, and the ten fixes that reliably restore it. Work the list top to bottom and you will almost always have your signature back long before you reach the end.
What "Gmail Signature Not Showing" Actually Means
Before touching a setting, it helps to separate the two very different things people mean when they say their signature vanished, because the fix for each lives in a different place. The first is a signature that was never inserted into the message at all — you open a fresh compose window and the bottom is empty. The second is a signature that is inserted but sits somewhere you did not expect, most often below a wall of quoted reply text where neither you nor your reader spots it. Naming which one you are looking at is the fastest route to a solved problem, and it is why Gmail signature not showing is almost never a case of lost data.
A Gmail signature is not part of any single email — it is a block of saved text and formatting that Gmail is told to paste into new messages automatically. That distinction matters, because it means the signature can be perfectly intact in your settings while zero emails actually carry it. If the "attach it automatically" instruction is switched off, every message you send will look bare even though the signature itself is untouched. Understanding that split is what turns a panic into a thirty-second settings change.
The single most useful test takes ten seconds: open Gmail on a desktop browser, click Compose, and watch the empty body. If your signature appears the instant the window opens, your signature is healthy and any missing sign-off is a per-message or per-device issue further down this list. If the body stays blank, the automatic insertion is off and Fix 1 will solve it outright. Run that test first, because it tells you whether you are chasing a defaults problem or a display problem — and the two never share a cause.
Fix 1: Assign the Signature to New Emails and Replies
This is the cause of the overwhelming majority of Gmail signature not showing reports on desktop, so start here even if you are certain you set it up correctly. Gmail keeps the signature text and the instruction to use it as two separate settings. You can write a beautiful signature, save it, and still send blank emails forever because the "signature defaults" were never pointed at it.
On a desktop browser, do this:
- Click the gear icon (top right) and choose See all settings.
- Stay on the General tab and scroll down to the Signature section.
- Confirm your signature text is actually there in the editing box. If it is, the text is fine — the problem is below it.
- Find the Signature defaults control. It has two dropdowns: For new emails use and On reply/forward use.
- Both will often read No signature. Change each one to the name of your signature.
- Scroll to the very bottom and click Save Changes — this step is skipped constantly and nothing takes effect without it.
Those two dropdowns are the switch that turns automatic insertion on. If For new emails use says No signature, a fresh compose window will always be blank; if On reply/forward use says No signature, your replies go out bare even when new mail is fine. Set both, save, then open a new compose window to confirm. Nine times out of ten, pointing the defaults at your signature ends a Gmail signature not showing problem on the spot. If you also manage your account for outreach or cold email at scale, getting a consistent sign-off on every send matters even more — our guide on how to warm up a Gmail account explains why steady, human-looking mail helps deliverability.
Fix 2: The "Before Quoted Text" Trap on Replies
If your signature shows up on brand-new emails but seems to vanish on replies, it is almost certainly not missing — it is being pasted at the very bottom of the message, underneath the entire quoted conversation you are replying to. Because Gmail collapses quoted text behind the small "..." trim button, your signature ends up hidden below that fold, and both you and your reader have to expand the thread to see it. This is one of the most misdiagnosed forms of Gmail signature not showing, because the signature is present and correct, just buried.
Gmail has a dedicated setting to fix this. In Settings → General → Signature, look for the checkbox labelled Insert this signature before quoted text in replies and remove the "--" line that precedes it. Tick it and save. From then on, your signature sits directly under what you typed, above the quoted history, exactly where a reader expects a sign-off to be.
There is a related quirk worth knowing: Gmail deliberately shows your signature only once per thread in its own conversation view, to avoid stacking the same block on every back-and-forth. That is a display convenience on your side, not a sign the signature failed to send — the recipient still receives it on each message unless their own client trims it. If replies were your only complaint, this fix and that reassurance usually close the case.
Fix 3: Multiple Signatures and the Wrong Default
Gmail lets you save several named signatures — one formal, one casual, one for a side project — and that flexibility is a common hidden reason for Gmail signature not showing. If you created a second signature and never told the defaults which one to use, or you deleted the one that was set as default and left the dropdown pointing at nothing, your emails go out blank while several perfectly good signatures sit unused in settings.
Open Settings → General → Signature and take stock of what is actually there:
- Every saved signature is listed by name down the left of the signature box. Click each to confirm its contents.
- Delete any empty or duplicate signatures that might be selected as the default — an empty signature set as default produces a blank sign-off that looks identical to no signature at all.
- In Signature defaults, make sure both dropdowns name the specific signature you want, not a deleted or empty one.
- Remember you can also switch signatures per message: in any compose window, click the pen icon at the bottom toolbar to pick a different saved signature for that one email.
The pen-icon switcher is useful once you know it exists, but it also explains the mystery where one email had a signature and the next did not — a signature chosen manually applies only to that message. Once your defaults point at a real, non-empty signature, the automatic behaviour becomes predictable again and the intermittent Gmail signature not showing pattern stops.
Fix 4: Your Phone Has Its Own Separate Signature
This is the fix that catches almost everyone who says their signature "disappears the moment I send from my phone." The Gmail mobile app does not read the signature you set on the web. It keeps a completely separate mobile signature, and until you set that one, every email sent from the app goes out with no sign-off at all — or with the generic "Sent from my phone" style line if one was ever added. Two independent settings on two devices is the single most common structural reason for Gmail signature not showing when desktop looks fine.
On Android, set the mobile signature like this:
- Open the Gmail app, tap the menu (three lines, top left), then scroll down to Settings.
- Tap the specific account — signatures are per-account, so a multi-account phone needs each one set.
- Tap Mobile Signature, type your sign-off, and confirm.
On iPhone or iPad, the path is nearly identical:
- Open the Gmail app, tap the menu, then Settings, then your account.
- Tap Signature settings, switch the toggle on, and enter your text.
One important limitation to set expectations: the mobile signature on the Gmail app is plain text only. You cannot carry over the images, coloured fonts, links and layout from your desktop signature — the phone gives you a single block of text. If you rely on a rich signature everywhere, some people work around this by keeping the mobile version short and clean. Either way, setting the mobile signature is what ends the device-specific version of Gmail signature not showing, and it is worth checking on every phone and tablet you send from.
Fix 5: Send-As Aliases and Delegated Accounts
If you send mail from more than one address inside a single Gmail account — a custom domain, an old alias, a shared team address added under "Send mail as" — your signature can appear on some outgoing mail and not others. That is because signature defaults are tied to identity, and switching the From address in a compose window can switch, or drop, the signature. When only certain senders are affected, aliases are the prime suspect behind Gmail signature not showing.
Check it this way. Open a compose window and look at the From line — if you have multiple send-as addresses, there is a dropdown there. Switch between them and watch the signature area: you will often see it change or disappear depending on which identity is selected. In Settings → General → Signature, the signature defaults can be set with a specific address in mind, so make sure the address you actually send from has a signature assigned rather than defaulting to none.
Delegated accounts add another wrinkle. If you manage someone else's inbox through Gmail delegation, mail you send on their behalf follows their signature rules, not yours, and by default may carry no signature unless it was configured. The same is true of shared mailboxes. Multi-account operators who run several inboxes for different projects hit this constantly — if that is you, our overview of using Gmail accounts with full recovery access covers how identities and access are structured, and our main aged Gmail accounts page explains how clean, established accounts keep each identity separate. Sorting out which identity owns which signature is what resolves the alias-driven form of Gmail signature not showing.
Fix 6: Image Signatures That Load as a Broken Box
A signature that contains a logo or headshot can look present in your settings and still arrive at the recipient as an empty rectangle, a red X, or nothing at all. This is a specific and frustrating flavour of Gmail signature not showing, because the text half of the signature is fine while the image half silently fails. The cause is almost always how the image is hosted or the permissions on it.
Work through these image-specific checks:
- Hosting and permissions. If your signature image is pulled from Google Drive or a private server, the recipient's mail client cannot fetch a file they have no permission to view, so it shows a broken placeholder. Host signature images somewhere public and always-available.
- Insert, do not paste. Use the image icon in the signature editor to add pictures rather than copy-pasting from a document, which can embed a fragile temporary link.
- Recipient image blocking. Many inboxes block remote images by default until the reader clicks "display images." To them, your image signature simply is not there until they choose to load it — nothing you can fix from your end except keeping critical details as text.
- Size and format. Oversized images can be stripped or fail to load; keep signature graphics small and in a common format like PNG or JPG.
The practical rule is to never put anything essential — your name, phone number, or a legal disclaimer — inside an image, because any reader with images turned off will lose it. Keep those as real text and treat the logo as decoration. That approach removes the image-driven cause of Gmail signature not showing for the majority of your recipients regardless of their settings.
Fix 7: Plain Text Mode Is Stripping It
Gmail's compose window has a hidden plain text mode that removes all formatting from a message — and when it is on, it can strip a formatted signature down to nothing or refuse to insert it. People switch it on by accident through the compose menu and then cannot work out why their sign-off evaporated. It is an easily missed cause of Gmail signature not showing, especially for anyone with an image or richly styled signature.
To check, open a compose window, click the three-dot More options menu at the bottom right of the toolbar, and look at Plain text mode. If it has a tick beside it, plain text mode is active — click it to switch back to rich formatting. Be aware that toggling it will warn you that current formatting is removed, so do this on a fresh draft rather than one you have already written.
Once rich formatting is restored, open a new compose window and confirm the signature returns. This same setting is worth remembering whenever any styling in Gmail refuses to appear, not just signatures. If your inbox has felt generally sluggish or has been dropping formatting and other elements since the recent redesign, our guide on why Gmail is so slow in 2026 lists the interface tweaks that lighten it and restore normal behaviour.
Fix 8: Cache, Extensions and a Stale Compose Window
Sometimes the signature is configured perfectly and the fault is the browser drawing an old, cached version of the compose window. A stale cache, a misbehaving extension, or a compose panel that has been open for hours can all produce a phantom Gmail signature not showing that has nothing to do with your settings — the signature is fine, the page just is not rendering it.
Clear these environmental causes in order:
- Hard refresh Gmail. Close every open compose window, then reload the tab with Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac) to force a fresh copy of the interface.
- Test in an Incognito or Private window. If the signature appears there, a cached file or an extension in your normal window is the culprit.
- Disable extensions. Signature managers, ad blockers, privacy tools and email trackers can all interfere with the compose window. Turn them off one at a time and retest.
- Clear cache and cookies. If Incognito worked but normal mode still fails, clearing Gmail's cached data usually settles it.
- Try another browser. A quick test in a different browser tells you instantly whether the problem is your account or your environment.
Because these are display glitches rather than account faults, they typically clear in under two minutes and rarely come back. If clearing the cache fixes it once but the Gmail signature not showing issue returns after every restart, suspect a specific extension and leave it disabled. The same cache-and-extension checklist resolves a surprising range of Gmail oddities — it is the same first step we recommend in our guide to Gmail not sending emails when a compose action stalls for no obvious reason.
Fix 9: Workspace Admin Footers and Overrides
If you are on a work or school account rather than a personal one, your administrator has controls that can override or replace what you set. A Google Workspace admin can append an organisation-wide footer to every outgoing message, and can, in some configurations, limit or standardise personal signatures. When your careful personal signature is being ignored or swapped for a company block, an admin policy is the reason behind the Gmail signature not showing you expected.
There are two distinct things happening at the admin level that users confuse for a bug:
- Appended compliance footers. Admins can attach a legal or branding footer to all outbound mail at the server level. This is added after your message leaves, so you never see it in your own sent copy — which makes people think their own signature failed when it did not.
- Centrally managed signatures. Some organisations push a standard signature to every employee, and that managed block can suppress or replace the one you set personally.
If you are the administrator, these live in the Admin console under the Gmail settings for compliance and routing. If you are an ordinary user and your personal signature keeps being overridden, the fastest resolution is to ask your IT team what signature policy is in force rather than hunting through your own settings — no personal fix overrides an org-level rule. Ruling the admin layer in or out is what closes the Workspace version of Gmail signature not showing.
Fix 10: It Shows for You but Not Your Recipients
The most confusing case of all is when the signature is clearly there every time you compose, yet people insist your emails arrive without it. Here the signature is genuinely being sent — the disappearance happens on the receiving end. This receiver-side Gmail signature not showing has a handful of predictable causes, and knowing them stops you from endlessly re-checking settings that are already correct.
The usual explanations are:
- Quoted-text burial. On replies without the "before quoted text" option ticked (see Fix 2), your signature lands at the very bottom under the trimmed history, so a reader who does not expand the thread never sees it.
- Recipient image blocking. If your signature is mostly an image, anyone with remote images blocked sees a blank space where it should be until they choose to load images.
- Client-side trimming. Some mail apps, especially on mobile, collapse or hide signatures and repeated blocks in a thread to save space.
- Plain-text conversion. A recipient whose client forces plain text will strip your fonts, colours and images, leaving only the raw text of the signature.
The defensive fix is the same one that solves several problems above: keep every essential detail as real, selectable text placed above the quoted history, and treat images and styling as optional decoration. A signature built that way survives image blocking, plain-text conversion and aggressive trimming, which is what finally ends the receiver-side Gmail signature not showing complaints for good. If you run outreach across many inboxes, consistency here is part of a wider deliverability picture — our piece on email deliverability and Gmail account age explains how a well-kept sender profile keeps your whole message, signature included, landing where it should.
Frequently Asked Questions
Why is my Gmail signature not showing on new emails but fine on my computer earlier?
The most likely reason is that the For new emails use dropdown under Settings → General → Signature is set to "No signature," even though the signature text is still saved. Point both signature-defaults dropdowns at your named signature and click Save Changes at the bottom of the page. If it worked earlier and then stopped, a browser cache glitch is the next suspect, so hard-refresh the tab and test a fresh compose window.
Why does my signature appear on desktop but not when I send from the Gmail app?
The Gmail mobile app keeps a completely separate signature from the web version and does not sync the one you set on your computer. Open the app, go to Settings, choose the specific account, and set the Mobile Signature (Android) or turn on Signature settings (iPhone). Note the mobile signature is plain text only, so images and formatting from your desktop signature will not carry across.
How do I stop my Gmail signature from appearing below the quoted reply text?
Go to Settings → General → Signature and tick the box labelled "Insert this signature before quoted text in replies and remove the '--' line that precedes it," then save. This moves your signature directly beneath what you type, above the quoted conversation, so it is visible instead of buried under the trimmed thread history that Gmail hides behind the "..." button.
Why does my Gmail signature image show as a broken box or red X to recipients?
The image is hosted somewhere the recipient's mail client cannot access — commonly a private Google Drive file or a server that requires permission — so it renders as a broken placeholder. Host signature images somewhere public, insert them with the image button rather than pasting, keep them small, and never place essential details like your name or phone number inside the image, since many inboxes block remote images by default.
Can a work or school account block my personal Gmail signature?
Yes. On a Google Workspace account, an administrator can append an organisation-wide footer to all outgoing mail or push a centrally managed signature that overrides your personal one. Because compliance footers are added after the message leaves your outbox, you will not see them in your sent copy. If your personal signature keeps being replaced, ask your IT administrator what signature or footer policy is in force.
I set everything correctly and my Gmail signature is still not showing — what now?
Work the environmental checks: hard-refresh Gmail, test in an Incognito window, disable extensions like signature managers and ad blockers one at a time, and confirm plain text mode is off in the compose window's three-dot menu. If the signature appears in Incognito, an extension or cached file in your normal browser is the cause. If it appears in a different browser, the issue is local to your usual one rather than your account.
A missing sign-off is almost never lost work — it is a switch waiting to be flipped, a second device with its own setting, or a signature quietly sitting below the fold of a reply.
