A handwritten signature in your email: how to add it in Gmail, Outlook and on your phone

Why put a handwritten signature in your email?

An email signature is mainly information: who wrote this and how to reach them. A handwritten signature adds something a font can't: a personal touch. For someone starting their career, a freelancer, a teacher or a creator this matters, because the reader feels at a glance that a real person wrote the message.

It isn't right everywhere. Larger companies often require a standard signature, and a personal image doesn't fit. For a quick internal reply it's unnecessary. A handwritten signature works best where the impression counts: an introduction, a proposal, a thank-you note, messages to clients.

A font shows what you wrote; handwriting shows that you wrote it.

How a good email signature is built

Before setting anything up, decide what goes into the signature. The most common mistake is putting everything into one image: signature, name, phone number, logo. It can look nice, but if the recipient's email app doesn't load images, they see nothing, and they can't copy your phone number.

• Your handwritten signature as an image. A small image with a transparent background; this is the personal part.
• Your name as text. Even if it's readable in the signature. That way it's searchable, copyable and visible when the image isn't.
• Title or role. One short line: “Graphic designer”, “Managing director”, “Maths teacher”.
• Contact details. Phone number, website; your email address is unnecessary, since that's where the message comes from.
• At most one extra. A logo or one social profile link is enough. Anything more feels cluttered.

Making the image: transparent background, crisp line

The quality of the image decides whether the signature looks elegant or cheap. A slightly crooked phone photo with a greyish paper background looks amateur rather than personal. The goal is a clean, dark line with no background.

1. 1
   Sign on clean white paper. A plain, unlined sheet and a black or dark blue pen with an even line. A fineliner or gel pen beats a faint ballpoint.
2. 2
   Scan or photograph it straight on. In daylight, without shadows, from directly above. Your phone's document scanner straightens and whitens the page.
3. 3
   Crop it tightly. Leave only the signature, with a thin empty margin around it.
4. 4
   Remove the background. Use an image editor or a background remover to make the paper transparent, and save it as PNG. JPG can't hold a transparent background.
5. 5
   Resize it. Aim for about 150–200 pixels tall; it will display smaller in your email, but this keeps it sharp on high-resolution screens.

Which version should you use?

An email signature is public: every recipient gets it, it can be forwarded and it can end up anywhere. So it's worth thinking about whether to use the same full, official signature you use on contracts and at the bank.

• Short version. A simplified form of your full signature, such as the capital and the start of your surname. Recognisably yours, but not identical to the official one.
• Monogram. Two initials in one sweeping mark. Looks good in small spaces and is very distinctive.
• First name only. Relaxed and friendly; works well in emails to clients and colleagues.
• Your full signature. If you do choose it, use a small, low-resolution image, not the large print-quality file.

Gmail on a computer, step by step

In Gmail in the browser, the signature lives in an editor where you can also insert an image. Menu names can differ slightly depending on your language and version, but the layout is similar.

1. 1
   Open settings. The gear icon at the top right, then “See all settings”.
2. 2
   Find the Signature section. On the “General” tab, scroll down, choose “Create new” and give the signature a name.
3. 3
   Type the text part. Your name, title and contact details, each on its own line.
4. 4
   Insert the image. Click the image icon in the editor toolbar to upload your PNG or pick it from Google Drive.
5. 5
   Set the size. Click the inserted image to see the size options (small, medium, large, original). Small or medium usually works best.
6. 6
   Choose the defaults. Below the signature, choose whether it appears on new emails and replies, then save changes at the bottom of the page.

Outlook: web, new and classic desktop

Several versions of Outlook exist side by side: Outlook on the web, the new Outlook app and classic desktop Outlook. You can create an image signature in all of them; the setting is just in different places.

1. 1
   Web and new Outlook: Settings. The gear icon at the top right, then “Signatures” under “Accounts”.
2. 2
   Create a new signature. Name it, type the text part, then insert your PNG with the editor's image icon.
3. 3
   Resize the image. Drag a corner of the inserted image or use its menu to make it smaller.
4. 4
   Set the defaults. In the same place, choose which signature appears on new messages and on replies and forwards.
5. 5
   Classic desktop Outlook. Here you reach the same editor through “File”, “Options”, “Mail” and the “Signatures” button; insert the PNG with the image icon here too.

Some versions of Outlook store the signature only on that device, others sync it with your account. If you email from more than one computer, check that it appears on each, and set it up there if it doesn't.

Apple Mail, iPhone and Android

On a Mac, you can create a signature in Apple Mail's settings under “Signatures” and simply drag the image into the editor. It's worth ticking the option to match the signature to the message's default font, so the text part stays consistent.

On phones it varies more. The iPhone's built-in Mail app keeps the signature in Settings, under Mail, and it's essentially text only. Most Android email apps also offer a plain text signature. If you want an image signature on your phone too, the most reliable route is an email app that syncs the signature you set up on your computer.

• For replies from your phone, text is enough. Your name and one contact detail are perfectly fine; nobody expects an image at the bottom of a quick reply.
• Don't paste it in by hand every time. Copying the image into each message is fiddly and its size easily gets distorted.
• Check your own email on a phone. Many recipients read on their phones: does your signature look good there too?

Dark mode and blocked images

Two things can make your signature look different for the recipient than for you: dark mode, and the fact that many email apps don't load images by default. It's worth preparing for both.

• Black ink can vanish on a dark background. If the image is transparent and the line is black, it can be almost invisible against a dark-mode background. Dark blue or a slightly lighter ink holds up better on both.
• Some apps recolour the message. In dark mode they adjust text and sometimes images to the background; the result varies by app. That's why you need to test.
• A white-background image is safer but less elegant. If many recipients read in dark mode, a white-background version always shows, but on a dark background it appears as a white rectangle.
• A blocked image leaves a blank or an icon. That's why your name and details must also be there as text. The signature is still complete; only the personal part is missing.
• Give the image a description. If your email app allows it, set your name as the image's alt text. It stays meaningful for screen readers and when images are blocked.

How does it look for the recipient? Test it

In your own email app, your signature almost always looks fine. The real question is whether it does for the recipient too. You can find out in a few minutes and avoid sending an important email with a distorted or invisible signature.

1. 1
   Send yourself a test email. Ideally to an address with another provider: from Gmail to Outlook or iCloud, and the other way round.
2. 2
   Open it on a computer and a phone. Same size, same proportions? It hasn't gone blurry or huge?
3. 3
   Turn on dark mode. Can you still see the line? If not, choose another ink colour or a white background.
4. 4
   Reply and forward. On replies and forwards, some apps treat the image as an attachment or repeat it. If that bothers you, use a text-only signature for replies.
5. 5
   Check it with images blocked. If your app allows, turn off automatic image loading: is it still clear who wrote the message?

Common mistakes

These mistakes come up for almost everyone adding a handwritten signature to their email for the first time. Each is easy to fix.

• Grey or yellowish paper background. The colour of the photographed page shows as a rectangle around the signature. Fix: transparent background, PNG format.
• An image that's too big. A half-screen signature at the bottom of the email. Fix: about two or three lines tall.
• Blurry, pixelated line. A source image that's too small, then enlarged. Fix: a higher-resolution source, scaled down in the email app.
• Everything in one image. Name, phone number and logo in a single graphic. Fix: only the signature is an image; everything else is text.
• Your full official signature in high resolution. Risky and unnecessary. Fix: a short version or a monogram, in a smaller image.
• Untested dark mode. A black line on a black background. Fix: test it, use dark blue ink or a white-background version.
• An image repeated in every reply. Dozens of identical signatures in a long thread. Fix: a short text signature for replies.

A good email signature is like a good handshake: brief, confident, and over before it outstays its welcome.

What an email signature doesn't replace

It's important to be clear: an image of your signature at the bottom of an email is decoration and introduction, not the signing of a document. If you need to sign a contract, a declaration or an official paper, there are separate methods for that, from signing on paper to placing a signature in a PDF to electronic signature services.

What kind of signature is acceptable in a particular situation is decided by the other party, the institution involved and the rules of the country, so for important matters always ask them. We cover signing documents in detail in our article on PDF and electronic signatures.

The easiest route: a ready file from Calligra

If you'd rather not deal with scanning, background removal and resizing, Calligra does it for you. With the Atelier package you can download your designed signature as a ready email signature image: transparent background, a crisp high-resolution line, sized for email, for Gmail, Outlook and Apple Mail.

You also get short and monogram versions of your signature, so you don't have to put your full official form into your emails. The transparent PNG and the vector SVG come with it too, for documents and electronic signatures.

If you don't yet have a signature you'd happily put at the bottom of your emails, start with the basics: this guide walks you step by step through creating your own.
