iPhone Email Signature: How to Add, Change or Remove It on iPhone, iPad and Mac Mail

To change your email signature on an iPhone, open the Settings app, tap Apps, then Mail, then Signature (below Composing). Delete "Sent from my iPhone" and type your new signature. That path applies to iOS 18 and later, including iOS 26 and the current iOS 27. On iOS 17 or earlier, the Apps step doesn't exist: go to Settings > Mail > Signature.

Apple's Mail app on iPhone and iPad officially supports text-only signatures. Below you'll find the exact steps for iPhone, iPad and Mac, how to set a different signature per account, and the widely used workaround for getting a signature with a logo onto your phone, including what Apple does and doesn't support.

How to change your email signature on iPhone (iOS 18, 26 and 27)

1. Open the Settings app (the grey gear), not the Mail app. The Mail app itself has no signature setting.
2. Scroll down and tap Apps.
3. Tap Mail. If you have many apps, type "Mail" in the search field at the top of the Apps list.
4. Scroll down to the Composing section and tap Signature.
5. Tap the text field, delete the existing text and type your signature.
6. Tap the back arrow at the top left. The signature saves automatically.

Open Mail, start a new message, and your signature is at the bottom.

Not sure which iOS you have? Go to Settings > General > About and look at iOS Version. Apple moved app settings into the Apps section in iOS 18, which is why older guides (and many signature tools' help pages) still send you to Settings > Mail. If you don't see Mail on the main Settings screen, you are on iOS 18 or later and need the Apps step.

On iOS 17 or earlier

Go to Settings > Mail, then tap Signature below Composing. Everything else works the same.

How to remove "Sent from my iPhone"

"Sent from my iPhone" is simply the default signature text, the email version of turning up to a meeting in pajamas. To remove it, go to Settings > Apps > Mail > Signature, tap into the field, delete the text and tap back. If you leave the field empty, your emails go out with no signature at all.

If the line keeps coming back, you have more than one account and are using Per Account: each account has its own field, and you need to clear (or replace) each of them.

Set a different signature for each email account

If your iPhone has both a work and a personal account, give each its own signature:

1. Go to Settings > Apps > Mail > Signature.
2. Tap Per Account at the top.
3. You now see one field per account. Type a signature in each.

Choose All Accounts to go back to one shared signature. There is no separate signature for replies on iPhone: the signature you set is added to new messages, replies and forwards alike.

What the iPhone signature can and can't do

Apple's iPhone User Guide is direct about this: "You can only use text in your Mail signatures." In practice:

• Text: yes. You can type several lines and include a phone number and website. Most email apps let the reader tap a phone number or web address to call or open it.
• Bold, italic, underline: basic styling is possible. Select a word in the signature field and look for the text formatting option (B/I/U) in the menu that pops up.
• Logo, photo, social icons, colors and layout: not through the settings field. You can't insert an image there.
• Which app it applies to: only Apple's Mail app. If you send from the Gmail app or the Outlook app on your iPhone, those apps use their own signature settings. See our guides for the Gmail app signature and the Outlook mobile signature.

A good text signature is still perfectly professional on a phone: name, title, company, phone, website. Our professional email signature guide has examples of what to include.

How to add an HTML signature with a logo on iPhone (the copy-and-paste workaround)

To get a designed signature (logo, colors, social icons) into iPhone Mail, people use a workaround: you copy a finished signature out of an email and paste it into the Signature field. Apple doesn't document this method, so treat it as unofficial. It has kept working across recent iOS versions according to signature tool guides updated in 2026, but Apple could change it in any update, which is why the last step below is a test.

Before you start: the images in your signature must be hosted online, linked rather than attached. A signature built in a proper generator is set up this way. A signature you made by pasting a logo file into an email is not, and the logo will either vanish or turn into an attachment.

1. Create the signature. Use a signature generator, or your desktop email program, and check it looks right.
2. Email it to yourself. Send an email containing only the signature to an address you read in Mail on your iPhone.
3. Copy it on your iPhone. Open that email in Mail, touch and hold on the signature, then drag the selection handles so they cover the whole signature, from the top of your name to the last line. Tap Copy.
4. Paste it into Settings. Go to Settings > Apps > Mail > Signature (pick the account under Per Account if needed), delete the old text, touch and hold in the field and tap Paste.
5. Undo the reformatting. iOS often strips the styling right after you paste, so the signature looks like plain text. Immediately shake your iPhone and tap Undo in the prompt that appears (it's often labeled "Undo Change Attributes"). The original design comes back. If nothing happens when you shake, check that Settings > Accessibility > Touch > Shake to Undo is on, or swipe left with three fingers to undo instead.
6. Save and test. Tap back to leave Settings. Send a test email to another address and check it on both a phone and a computer, including whether the logo loads.

A few tips that make this work better:

• Keep it narrow. A signature wider than roughly 600 pixels gets squeezed on a phone screen. Our email signature size guide has the numbers.
• Copy only the signature. If you also copy blank lines or a sign-off ("Best regards"), they become part of the signature.
• Do it once per device. Apple's guide doesn't describe the iPhone signature syncing to other devices, so plan to set it up separately on your iPad.

Signguin makes the first step easy: type your work email and it pulls your logo, brand colors and contact details from your company website, then shows a live preview in phone and desktop mode, in light and dark. The logo and icons are hosted by Signguin and stored at double resolution, so they stay sharp on a Retina screen and don't break if your website changes. If you open your signature in Signguin on the iPhone itself, you can tap Copy signature there and skip steps 2 and 3, then continue with the paste and undo steps above. The free plan has three designs and doesn't ask you to sign up.

More layouts are in our email signature examples.

iPad email signature

The iPad works exactly like the iPhone. Go to Settings > Apps > Mail > Signature (on iPadOS 17 or earlier: Settings > Mail > Signature), type your signature and use Per Account if you have several accounts. Apple's iPad guide carries the same note: only text is supported. The copy-and-paste workaround above works the same way, with one difference: shaking an iPad isn't practical, so use the three-finger swipe left (or Command-Z on a connected keyboard) to undo the reformatting.

How to add a signature in Apple Mail on Mac

The Mac version of Mail is much more capable: it supports images, links, fonts and several signatures per account.

1. Open the Mail app on your Mac.
2. In the menu bar, choose Mail > Settings, then click Signatures. On macOS Monterey and earlier, it's Mail > Preferences > Signatures.
3. In the left column, select the email account the signature is for.
4. Click the + button below the middle column and type a name for the signature. The name is what you'll see in the Signature menu when writing an email.
5. In the right column, type your signature. Use the Format menu for font, color and alignment, and the Edit menu to turn text into links. To add an image, drag it into the right column.
6. Below the columns, use the Choose Signature pop-up to pick which signature is added automatically for that account.
7. Close the window. Changes save automatically.

Three settings on that screen trip people up:

• All Signatures vs an account. If you create a signature while All Signatures is selected in the left column, it isn't assigned to anything yet. Drag it from the middle column onto an account before you can use it. You can drag the same signature onto several accounts.
• Always match my default message font. When ticked, Mail replaces your signature's fonts with the default message font from your Fonts & Colors settings. For a plain text signature that's fine. For a designed (HTML) signature, untick it, otherwise your carefully chosen fonts and sizes get overwritten.
• Place signature above quoted text. When ticked, your signature sits directly under your reply instead of at the very bottom below the quoted email. Most people want this on.

The Choose Signature pop-up can also rotate several signatures At Random or In Sequential Order, or be set to None. While writing an email, you can switch signatures with the Signature pop-up menu in the message window.

Adding a designed (HTML) signature on Mac

1. Untick Always match my default message font for the account first.
2. Open your signature in a browser (for example in the generator's preview), select the whole signature and copy it.
3. In Mail > Settings > Signatures, create a new signature, click into the right column, select the placeholder text and paste.
4. Send yourself a test email.

Use a signature with hosted images rather than dragging image files in for a designed signature. Apple notes that depending on how a recipient's mail server handles signatures, a signature may arrive as an attachment or as an image. Linked images avoid most of those surprises. If you use iCloud Drive with Mail turned on in its options, your Mac signatures stay available on your other Macs.

iCloud Mail on the web

If you use Mail on iCloud.com, signatures are plain text. Go to icloud.com/mail, open the settings menu at the top of the Mailboxes list, choose Settings, select Composing, tick Add a signature and type it. Untick the box to stop using it.

iPhone email signature not working? Quick fixes

My signature doesn't appear. Check which app you're sending from. The iPhone signature only applies to Apple's Mail app, not to Gmail or Outlook. Also check Per Account: you may have set the signature for a different account.

The formatting disappeared after pasting. Shake to undo straight after pasting, before you edit anything else. If the design still doesn't come back, clear the field, copy the signature from your email again and repeat.

The logo doesn't show for recipients. The image is probably attached instead of linked, or the link points to a file that moved. Rebuild the signature with hosted images.

The signature looks huge or squeezed on the phone. It is too wide or the images have no fixed size. Use a layout under about 600 pixels wide with fixed-size images. If you're also setting up Outlook on your computer, see how to add a signature in Outlook.

FAQ

Where is the signature setting on iPhone in iOS 18 and later?

It moved. Open Settings, tap Apps, tap Mail, then Signature below Composing. Before iOS 18, Mail had its own entry on the main Settings screen (Settings > Mail > Signature). The same applies to iPad. There is no signature option inside the Mail app itself.

Can I add a logo to my iPhone email signature?

Not through the official setting: Apple says only text is supported. The common workaround is to email a finished signature with hosted images to yourself, copy it, paste it into the Signature field, then shake to undo the automatic reformatting. Always send a test email afterwards, because Apple doesn't support this method officially.

Do iPhone, iPad and Mac share the same signature?

Not automatically. Apple's guide only mentions syncing signatures between Macs through iCloud Drive. Your iPhone and iPad signatures are set in each device's own Settings, so set them up separately and keep them identical by pasting the same signature on each.

How do I use different signatures for work and personal email on iPhone?

Go to Settings > Apps > Mail > Signature and tap Per Account. You get one field per account, so your work account can carry your full company signature and your personal account can have a simple name, or nothing at all.

Why does my iPhone signature not appear in Gmail or Outlook?

Because those are separate apps with their own settings. The iPhone Signature setting only works in Apple's Mail app. In the Gmail app, use Settings > Signature settings for each account. In the Outlook app, the signature is under the app's own mail settings.

How do I change my signature in Apple Mail on Mac?

Choose Mail > Settings > Signatures (Mail > Preferences on macOS Monterey or earlier), select the account on the left, click the signature in the middle column and edit it on the right. Changes save when you close the window. Use Choose Signature to set which one is added automatically.
