Where to find and edit your email signature on iPhone
Your email signature on iPhone lives in the Mail app settings, not in individual emails. Open Settings, scroll down and tap Mail, then scroll to the bottom of that screen and tap Signature. You will see options for each email account you have set up — tap the account whose signature you want to change.
The signature field shows whatever text is currently set. Delete it entirely if you want no signature, or replace it with new text. Changes save automatically when you leave the screen. The next email you send from that account will include your new signature.
If you have multiple email accounts on your iPhone, each one can have its own signature. Tap each account name separately to set a different signature for Gmail, Outlook, work email, or any other account you use.
Key Takeaways
- Email signatures on iPhone are set in Settings > Mail > Signature, not in the Mail app itself.
- Each email account can have a different signature — change them one at a time by tapping the account name.
- You can include line breaks, contact information, job titles, or any text you want; just type it into the signature field.
- Changes take effect when ready on new emails you send, but do not change signatures on emails you have already sent.
- Deleting all text in the signature field removes the signature entirely from that account.
What text to include in your signature
A signature can be as straightforward as your name or as detailed as your full contact information. Common additions are your phone number, job title, company name, website, or a short professional statement. Type whatever you want — there is no character limit that matters in practice.
If you want text on separate lines, tap the return key on your keyboard to create line breaks. For example, you could type your name, press return, then your title, press return again, then your phone number. Each will appear on its own line in your emails.
Keep in mind that your signature appears at the bottom of every email you send from that account unless you delete it before hitting send. If you use the same account for both professional and personal emails, choose text that works for both contexts.
Removing or disabling a signature
To remove a signature entirely, go back to Settings > Mail > Signature, tap your account name, and delete all the text in the field. Leave it blank and tap back. Your emails will no longer include any signature.
You cannot turn a signature on and off without editing it — there is no toggle switch. If you want to use a signature sometimes but not always, you will need to delete it from the signature field and then re-add it each time you want it back. Alternatively, you can keep a signature set and straightforward delete it from individual emails before you send them.
Signatures on different iPhone email accounts
If you have Gmail, Outlook, Yahoo, iCloud, or a work email account on your iPhone, each one can have a completely different signature. Go to Settings > Mail > Signature and you will see a list of all your accounts. Tap each one separately to set or change its signature.
This is useful if you want a professional signature on your work email but a casual one on your personal Gmail, or no signature at all on a secondary account. The signature you set for each account will only appear on emails sent from that specific account.
Why your signature might not appear
If you set a signature but it is not showing up in your sent emails, check that you are sending from the correct account. Tap the From: field in a new email to confirm which account is selected — the signature belongs to that account only, not to all your email accounts.
If you recently changed your signature and it is not appearing yet, try closing the Mail app completely and reopening it. Sometimes the change needs a moment to sync. If you are using an older version of iOS, update your iPhone to the latest version available, as email settings sometimes behave differently on older software.
Signatures also do not appear in the compose preview on your screen — you will only see them in the actual email once it is sent. This is normal behavior.
Editing your signature on a Mac or iPad
If you also use a Mac or iPad with the same email accounts, you can set signatures on those devices too. On a Mac, open Mail, go to Mail > Preferences > Signatures and choose your account. On an iPad, use Settings > Mail > Signature just like on iPhone.
Signatures set on one device do not automatically copy to another device. If you want the same signature on your iPhone and iPad, you will need to type it in on both. If you change a signature on your Mac, your iPhone will not update automatically — you will need to change it in iPhone settings as well.
Frequently Asked Questions
Can I use different signatures for different recipients?
No — iPhone Mail does not support conditional signatures based on who you are emailing. Each account has one signature that appears on all emails sent from that account. If you need different signatures for different people, you will need to add or edit the signature manually in each email before sending.
Can I add a logo or image to my email signature?
The signature field in iPhone settings only accepts text, not images or logos. If you need a logo in your signature, you will have to add it manually to each email, or use a third-party email app that supports formatted signatures. Most business email apps available in the App Store offer this feature.
Will my signature appear on emails I forward or reply to?
Yes — when you reply to or forward an email, your signature will be added at the bottom of your response. If you do not want a signature on a particular reply, you can delete it from the compose field before sending.
What happens to my signature if I delete an email account from my iPhone?
The signature for that account is deleted along with it. If you add the account back later, you will need to set a new signature. The signature is stored in your iPhone settings, not on the email server, so removing the account removes the signature too.
Can I copy a signature from one account to another?
Not automatically — you will need to type it in separately for each account. The easiest way is to go to the first account's signature, select and copy the text, then go to the second account and paste it. You can then edit it if needed.
