How to Add a Signature in Gmail (Set It Up Correctly)

Setting up a Gmail signature

Settings (gear icon) > See all settings — opens the full settings page, distinct from the smaller quick-access settings panel that appears by default.

Scroll to “Signature” — found under the General tab, roughly partway down the settings page.

Create and format your signature — add text, links, or an image using the built-in rich text editor, similar to formatting options within an email itself.

Set defaults for New emails AND Replies — two genuinely separate dropdowns; it’s easy to set one and completely miss setting the other, resulting in the signature appearing on new emails but not replies, or vice versa.

Click “Save Changes” at the bottom — the signature genuinely won’t apply to any outgoing email until this final step is clicked.

Adding your signature

Go to Settings > See all settings — accessed via the gear icon in the top-right corner of the Gmail interface.

Find “Signature” under the General tab — click “Create new” to start building a signature from scratch.

Type and format your signature text — adding a logo, relevant links, or contact information as genuinely needed for the specific use case.

Set it as default and Save Changes — for both New emails and Replies/forward separately, then scroll down and click Save Changes at the very bottom of the page.

Adding an image or logo to a signature

The signature editor’s toolbar includes an image insert option, allowing a company logo or a personal headshot to be added directly. It’s worth using a genuinely appropriately sized image rather than an oversized one, since an overly large image can make the signature look disproportionate or push important text below the visible fold in a recipient’s inbox preview.

Worth knowing: some email clients block external images by default until the recipient specifically clicks to display them, meaning an image-based signature may not always render immediately for every recipient — keeping essential contact information as actual text within the signature, rather than embedded only within an image, ensures it’s still readable even if the image itself doesn’t load.

Multiple signatures for different accounts or purposes

Gmail supports creating multiple signatures, useful for someone managing separate email aliases or needing a different signature style for different types of correspondence (a more formal signature for client emails versus a shorter one for internal team messages, for instance). Each saved signature can be set as the default independently, and it’s also possible to manually select a different signature when composing a specific email rather than always using whichever one is set as the default.

A worked example: a small business setting up consistent team signatures

Say a small business owner wants every team member’s email to include a consistent, professional signature — company logo, name, title, and contact details — rather than each person building their own inconsistent version, or worse, no signature at all.

Rather than emailing each employee instructions and hoping everyone follows them consistently, they build one signature template first in their own Gmail account, including the company logo (uploaded as an appropriately sized image, not an oversized one), name and title placeholders clearly marked, and a consistent font and color scheme matching the company’s actual branding. They then copy the signature’s HTML source and share simple setup instructions with the team, having each person paste it in and swap just their own name and title into the placeholder text.

For anyone on Google Workspace specifically (rather than personal Gmail accounts), a workspace admin can instead set this up centrally through the Google Admin console’s Gmail settings, pushing a single consistent signature template to every user in the organization automatically, removing the need for each person to manually copy and configure anything themselves — a considerably more reliable approach for a team larger than a handful of people, where manual setup consistency becomes genuinely harder to enforce.

Once set up, they specifically test by sending both a new email and a reply from one team member’s account, confirming the signature appears correctly in both cases — catching the common New-emails-versus-Replies gap before it becomes a pattern across the whole team’s outgoing mail rather than an isolated one-person mistake.

Signatures with a call-to-action or banner

Beyond basic contact information, some signatures include a promotional banner or a specific call-to-action — a link to book a meeting, a recent piece of content, or an upcoming event. These are built the same way as a logo, inserted as an image (optionally wrapped in a clickable link via the editor’s link-insert tool) directly within the signature editor.

It’s worth keeping this kind of addition genuinely modest in size and frequency of change — a signature that looks meaningfully different or promotional on every single email can start to feel less like a professional signature and more like an advertisement attached to routine correspondence, which isn’t always the impression actually intended.

A useful middle ground is rotating a promotional element occasionally — monthly or quarterly, tied to an actual event or announcement — rather than either never updating it or changing it so often that recipients stop registering it as meaningful content at all worth actually paying attention to in a busy, crowded inbox each day of the working week, month after month, year after year, indefinitely.

Plain text vs. formatted signatures

For situations where a simple, minimal signature is genuinely preferred — some recipients or industries favor a plain, unstyled sign-off over a logo-heavy formatted one — Gmail’s signature editor supports plain text just as easily as rich formatting, simply by not applying any bold, color, or image elements. A plain text signature also renders more predictably across different email clients, since it has nothing for a recipient’s client to potentially strip or alter on receipt.

Signature not appearing?

Forgot to click “Save Changes” — at the very bottom of the Settings page; without this click, no changes made above actually take effect.

Set default for New emails but not Replies/forward, or vice versa — both dropdowns need to be set independently for consistent coverage across all outgoing emails.

Signature appears in Gmail but not on mobile — the Gmail mobile app maintains its own separate signature setting, found within the app’s own Settings menu, distinct from the desktop version.

Image or logo not displaying for recipients — some email clients block external images by default; this is a recipient-side setting outside the sender’s direct control.

Signature formatting looks different for recipients — some email clients strip or alter advanced formatting on receipt, which can occasionally make a heavily styled signature look different than intended once it actually arrives.
