How to Create an HTML iPhone Email Signature

Setup your own iPhone email signature with ease.

How to add a signature on iPhone

If you own an iOS device, you will be familiar with the standard iPhone email signature ‘Sent from my iPhone‘. This is fine if you are sending outgoing emails to friends, but it does not look very professional in business communications.

Changing the existing signature line in your email account is very straightforward:

  1. On the iPhone, open Settings in the mail app.
  2. Swipe down and choose Mail.
  3. Swipe down and tap Signature.
  4. Type your new signature text (this can be done for all accounts or on a per account basis).
  5. Select Mail.

This new signature will now be added to every new email you create. It’s recommended that you include your full name, job title, company name, phone number, and email address.

How to add an image to your iPhone email signature

To make your iPhone email signature look more professional, it should incorporate text, imagery, and dynamic HTML content. To find out how to add an image to your iPhone email signature, follow these instructions:

Note: This will work if you’re using an iPhone or an iPad.

  1. Create your default signature in an email client that supports HTML, e.g. Outlook or Gmail. Make sure you add content such as your logo, social media icons, and legal disclaimer.

  2. Send a blank message with the new HTML signature to your iPhone.

  3. Open the email on your iPhone. Find a part of the signature text that is not a web or email link. Press and hold this text.

    A section of the text is highlighted using the press and hold feature built into iOS.
  4. The context menu will appear over the text. Tap Select All, then Copy.

  5. Go into the iPhone email signature editor by going to Settings > Mail, Contacts, Calendars > Signature.
  6. Delete any text, tap and hold the screen until the context menu appears, and select Paste to copy the signature.


    The Context menu is triggered using the press-and-hold gesture.
  7. The new email signature will now appear in the editor. The original formatting will have been lost and it will appear slightly altered – this is normal so don’t panic!

    iOS automatically adds its own coding to the HTML source of the email signature. All you have to do is shake your iPhone to trigger the Undo Change Attributes context menu and select Undo.

  8. You’ve now successfully removed the additional iOS formatting.
  9. Go into the iPhone email app to see your new HTML email signature in all its glory. You’ll want to test it thoroughly before sending out any emails to other recipients.

Always remember to thoroughly test an iPhone email signature.

Centrally managing iPhone email signatures

This process only works for one mobile device at a time. You will find it much more difficult to get everyone to create and maintain a consistent organizational iPhone email signature. Also, your iPhone email signature images (and other formatting elements) will most likely not comply with your brand guidelines. This could also lead to missed marketing and business opportunities.

With Exclaimer’s email signature solutions, all iPhones will get full HTML email signatures every time. This maintains your professional image and brand consistency.
