The Gmail signature that looks
exactly how you want it to.
HTML email signatures that render perfectly in Gmail — on desktop, web, and mobile. Build yours with your photo, brand colour, and social links. Paste into Gmail in one click.
Installation
Five steps. Takes about two minutes once you've built your signature.
Fill in your name, title, company, contact details, and paste your photo and logo URLs. Choose your brand colour and font. The preview updates live — tweak until it looks exactly right.
One-time payment via Stripe. Once unlocked, click Copy Signature — this copies a rich HTML version of your signature to your clipboard. Not raw code. The actual rendered signature, ready to paste.
💡 Use the Copy Signature button, not Ctrl+C from the source code. The Copy button creates a special clipboard entry that Gmail recognises as formatted content — it pastes as a rendered signature, not HTML code.
In Gmail web, click the gear icon (⚙) in the top-right corner, then click See all settings.
On the General tab, scroll down to the Signature section. Click Create new, give it a name, then click inside the signature text box and press Cmd+V (Mac) or Ctrl+V (Windows). Your signature — with photo, colour, and layout — appears immediately.
💡 If Gmail shows a plain-text version instead of your formatted signature, try pasting in the Chrome browser specifically. Safari and Firefox occasionally strip rich clipboard content in Gmail's editor.
Below the signature editor, set your new signature as the default for New emails and Replies/forwards separately. Scroll to the bottom of the Settings page and click Save Changes.
💡 Gmail saves your signature on its servers — it'll appear on Gmail web, the iOS app, and the Android app automatically. No need to set it up separately on each device.
Why it matters
The Gmail signature editor lets you type text and add a photo manually. Here's what you're missing.
Gmail's built-in editor lets you add one image, but sizing it correctly alongside text requires HTML table layout. Without it, your photo floats awkwardly or sits above your details instead of beside them.
Your name, links, and icons in your exact brand colour. Gmail's native editor gives you a basic colour picker — HTML gives you precise hex control that applies consistently across every element.
Pasting raw LinkedIn URLs into Gmail's editor looks messy and unprofessional. HTML signatures use properly sized, linked icons in your brand colour — one tap to connect.
A Calendly link in Gmail's text editor is just a URL. In an HTML signature it becomes a styled button with your colour and a calendar icon — much more likely to get clicked.
Gmail's native editor doesn't support two separate images in a structured layout. HTML lets you display your profile photo and company logo side by side in a clean, consistent format.
If your role requires a confidentiality notice or legal disclaimer, HTML lets you style it separately — smaller, lighter, visually distinct from your contact details.
Gmail deep dive
Gmail is one of the better email clients for HTML signatures — but it has its own quirks worth knowing about.
You can't paste raw HTML code into Gmail's signature settings and have it render correctly. Gmail's editor interprets it as plain text. The correct approach is to paste the rendered signature — a rich-text clipboard entry that carries the formatting invisibly. That's exactly what our Copy Signature button does.
✓ Handled automatically by the Copy Signature buttonWhen recipients open your email, Gmail fetches your profile photo from the URL you provided. This means your image must be hosted at a publicly accessible URL — not a local file, not a Google Drive link, not a Dropbox share. If the URL is private or behind a login, recipients see a broken image placeholder.
✓ The generator warns you if your URL looks non-publicThe Gmail mobile apps display your signature but don't always render it identically to the web version — particularly on very small screens. Table-based HTML with fixed pixel widths can overflow on mobile. Our signatures use max-width:520px and relative sizing to stay readable on any screen size.
Google Fonts, Adobe Fonts, and any @font-face declaration is stripped by Gmail before the email reaches the recipient. Whatever custom font you use in your signature code will fall back to Arial. This is why the generator only offers Gmail-safe system fonts — what you see in the preview is exactly what your recipients will see.
Some Gmail accounts are configured to block external images by default, showing a "Images are not displayed" banner. Recipients can click to load images, and Gmail remembers their choice per sender. Most professional Gmail accounts have images enabled by default — this mainly affects cold email to people who've never received mail from you before.
✓ Nothing you can do about this — it's recipient-sideOnce set as default, Gmail inserts your signature into new emails automatically. In replies and forwards, it inserts it below the reply text (or above, depending on your settings). You can configure this separately for new emails vs replies in Gmail Settings → General → Signature.
✓ Set both defaults when you install your signatureWhat to include
Not everything. Just the right things. Here's what earns its space.
As you want to be addressed professionally. If you go by a short form, use that — not your legal name.
Sets context immediately for recipients who don't know you. Especially important for cold emails and first introductions.
Mobile is usually best. Don't list three numbers — it creates friction rather than removing it.
Reinforces legitimacy and gives recipients somewhere to learn more about you before replying.
Research consistently shows that emails with a recognisable face attached are perceived as more trustworthy. Square crop, clean background, professional but approachable.
LinkedIn almost always. A second one if it's genuinely professionally relevant — not just because you have an account.
The single highest-leverage addition for anyone in consulting, sales, or client services. Removes the scheduling back-and-forth entirely.
Complete guide
Modern web design uses CSS flexbox, grid, and stylesheets. Gmail strips nearly all of it. The only layout method that renders consistently across Gmail web, Gmail iOS, Gmail Android, and every other email client is the one that dates back to the early web: HTML tables with inline CSS.
This isn't a workaround — it's the industry standard for HTML email. Every major email marketing platform (Mailchimp, HubSpot, Klaviyo) generates table-based HTML under the hood. Your signature is no different. Send Like a Pro generates properly structured table HTML so you never have to think about this.
Gmail enforces a 10,000 character limit on signatures. A typical HTML signature from Send Like a Pro runs between 1,500–3,500 characters depending on how many fields you fill in. You're very unlikely to hit the limit unless you add extremely long custom disclaimers or banner text.
When you click Copy Signature, the generator uses the Clipboard API to write two versions of your signature simultaneously: a text/html version (the formatted HTML) and a text/plain fallback. Gmail's signature editor reads the text/html version and renders it as a formatted signature — photo, colour, icons and all — exactly as it will appear to recipients.
This is different from copying text with Ctrl+C. If you copy the HTML source code and paste it into Gmail, it will paste as visible code — angle brackets and all. The Copy Signature button handles this correctly.
Gmail supports multiple saved signatures and lets you switch between them when composing an email. This is useful if you have multiple roles, email different audiences, or want a shorter signature for replies vs a fuller one for new introductions. You can install your Send Like a Pro signature alongside any others you already have — just give it a distinct name when you create it.
If your company uses Google Workspace, your administrator may have configured a server-side signature that's appended to all outgoing emails. This is separate from your personal Gmail signature. Your personal signature appears in the compose window; the admin signature is added after the fact. You can have both — they won't conflict. Check with your IT department if you're unsure whether your organisation uses server-side signatures.
Changed jobs? Rebranded? New phone number? Just rebuild your signature in the generator, copy it again, and paste it into Gmail Settings over your existing signature. Gmail overwrites the old one. Your form data is saved in your browser's localStorage, so your previous inputs will still be there — just update what's changed.
FAQ
Yes — that's what it's built for. The Copy Signature button creates a clipboard entry that pastes directly into Gmail's signature editor as a formatted signature (not code). No HTML knowledge needed.
Your signature will look consistent across Gmail, Apple Mail, and most modern email clients. The HTML uses table-based layouts and inline CSS — the same approach used by professional email marketing tools. Images are loaded from your hosted URL, so recipients with image-blocking enabled may need to click "Display images" to see your photo and logo.
Yes. Google Workspace uses the same Gmail interface and signature settings. Your personal Gmail signature (set in Settings → General → Signature) works the same way regardless of whether your email is a personal Gmail account or a Workspace account.
The Gmail iOS app supports HTML signatures, but setting them up requires a workaround. The easiest method: set your signature in Gmail web (desktop), and it will sync to your Gmail mobile app automatically. Alternatively, open Gmail web on your phone's browser, paste your signature in Settings, and save. The app will then use it.
No. There's no "Made with Send Like a Pro" or any other watermark. Your signature is entirely yours — the $8 payment is specifically so we don't need to add branding to cover costs.
A Gmail signature is automatically appended to every email you send. An email template is a saved draft you manually insert when needed. Signatures are for consistent branding on every email; templates are for frequently-repeated email content. Send Like a Pro builds signatures, not templates.
Yes — Gmail signature settings are per-account. If you're logged into multiple Gmail accounts, each has its own signature settings. You can build a separate signature in the generator for each account and install them independently.
Not at all. The generator handles all the HTML. You fill in a form, preview your signature, and paste it into Gmail. The only time you'd see any HTML is if you choose to download the .html file — and even then, you don't need to open or edit it.
