NOTE: This article explains how to deploy an HTML email signature with images on a single iPhone. To learn how to manage HTML email signatures on multiple iPhones connected to Google Apps, Office 365 or Microsoft Exchange accounts consult this guide.
The default iPhone email signature – ‘sent from my iPhone’ – has by now become sort of a running joke among users. With this in mind, if you are using your iPhone for professional correspondence, you might want to change it to something more appropriate. To do this you have to go to Settings App > Mail, Contacts, Calendars > Signature and type in your new byline.
However, if you want to go all the way and create a full blown HTML signature with images, links, etc., roll up your sleeves and follow these steps:
IMPORTANT: For the signature to work correctly on your iPhone the images must be linked. This is a default in most webmail clients like Gmail, but not a default in standalone email clients like Outlook (learn how to use a linked image in Outlook).

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

3. Open the email in your iPhone. Press and hold on a part of text that is not a link:

4. When the context menu appears, choose Select All and then Copy.

5. Go to the iPhone email signature editor (Settings App > Mail, Contacts, Calendars > Signature), if you already have an email signature configured – delete it, press and hold until the context menu appears and select Paste.

6. After you have pasted the email signature into the editor, you will notice that it lost its original formatting and has been slightly altered. This is because your iPhone automatically added its own coding to the HTML source of the signature. Shake your iPhone to trigger the Undo Change Attributes context menu and select Undo. This will remove additional undesired formatting introduced by your iPhone.

7. Go to your iPhone Mail app and initiate a new message (it should already contain the new signature).
IMPORTANT: Do not send the message. Instead, click Cancel, Save Draft. Go to Drafts (e.g. by holding the Compose button), locate the email and then copy and paste the signature from there according to steps 3 – 6.
