Frequently Asked Questions

Q1. I can't find iSignature in the global Settings application. How do I enter my signatures?

The signatures are created in the application itself, not in the global Settings application. The items that you see when you launch the application are the signature entries that have been pre-populated with examples and instructions for using the application.  To create your signatures, simply overwrite the pre-populated contents with the contents of your choice and/or add new ones.

To add a new signature, tap the "+" button.

To delete a signature, either swipe horizontally left across the signature title and then tap the "Delete" button or tap the "Edit" button, tap the "stop" sign, and then tap the "Delete" button.

To reorder signatures, tap the "Edit" button and grab the signature item you wish to move by the grabber on the right side and move it to the desired location.

To edit the name of a signature, tap the "Edit" button and then tap the signature title.

To copy a signature to the clipboard (e.g. for use in replying to emails), tap and hold the signature title in the list of signatures until "Copying..." appears.

To edit a signature, tap the (iOS 7) or the (iOS 5/6) button on the right side of each signature item in the main screen.  Then tap the field that you wish to change.  The "Contents" is the signature that will be included in the mail composition window and "Image" is the optional image to include below the "Contents".

To send an email with one of the signatures, tap the appropriate signature item in the list of signatures (iPhone) or the "Compose" button in the signature contents area (iPhone and iPad).  That will show the mail composition window with the selected signature.

Q2. The default signature shows up below the signature that I select with iSignature. Is this a bug?

No, this is not a bug. The current OS does not allow third party applications to access or replace the system provided signatures. Therefore, before using iSignature, please clear the default signature. If Apple ever provides a way for developers to access the system signatures, iSignature will be udpated accordingly.

Q3. Is there a limit for the number of lines that a signature can have?

No, iSignature does not place a limit on the number of lines in each signature.

Q4. Can I enter special characters such as curly braces, ampersand, yen symbol, bullet, etc.?

Yes. iSignature supports special characters. In fact, you can use any character that you would enter into a normal email.

Q5. Can I use HTML tags in the signature?

Yes. iSignature supports HTML tags. For example, the below HTML code will generate the email shown in the HTML Signature screenshot.

<b>Bold Text</b>
<i>Italic Text</i>
<u>Underlined Text</u>
<font color="red">Colored Text</font>

Q6. Can I include a picture in a signature?

Yes. iSignature allows you to assign any picture from your device's library of photos to each signature. See the Picture Example screenshot for a signature with a picture. The corresponding signature configuration screen can be seen here. Note that due to speed and size considerations, large images will be scaled down to a maximum resolution of 640x480 pixels.

Q7. What is the "Use In-App Mail" Option?

The option controls whether the mail composition is done within iSignature (i.e. "In-App") or in the Mail application.  "In-App" mail is suitable for most situations. However, you may want to compose the mail in the Mail application if you wish to read emails before or after sending your email, compose your mail by copying text from existing emails, etc.

Q8. What is the difference between the image "Attach" and "Inline" options?

If "Attach" is selected, the image will be included in the mail message as an attachment. In most cases, this is the preferrable option as it is the most compatible with a variety of mail clients. However, in this case, the positioning and display of the image may vary across different mail clients. "Inline" ensures that the image will be shown immediately below the signature contents but some mail clients strip inline images as an anti-spam measure.

Q9. Can I use iSignature for reply/forward emails?

Yes. The process to do so is as follows.

  • Initiate a reply/forward in the Mail application.
  • Open iSignature.
  • Tap and hold the desired signature to copy the signature contents into the clipboard.
  • Return to the Mail application.
  • Paste the signature into the mail composition window.

Q10. When composing an email, the From: account is set to my default email account. Is this a bug?

No, this is not a bug. iOS does not allow third-party applications access to the user's email account information. iOS pre-populates (forces) the From: account to the default user account for emails generated by third-party applications. If Apple ever provides a way for third-party applications to access the email accounts, iSignature will be udpated accordingly.

Q11. My signature picture is not displayed by my email client. Is this a bug?

No, this is not a bug. In some configurations some email clients, most notably Outlook 2007, refuse to display inline HTML images. If you experience this and cannot successfully configure your email client to display inline HTML images, please use the image "Attach" option. Alternatively, you can use an image link as follows.

  • Place your signature image on a publicly available web server.
  • Unselect the picture in iSignature.
  • Place the following at the end of your signature contents field:
    <b><img src="SIGNATURE_IMAGE_URL"></b>
    where SIGNATURE_IMAGE_URL is the URL of the signature image on the web server.

Q12. My signature picture shows up huge in received emails. Is iSignature enlarging it?

No, iSignature does not enlarge pictures. iSignature only downsizes the sizes of images that are larger than 640x480 pixels. Otherwise, it leaves the image size unchanged. If your picture is getting enlarged, it is probably because you used iTunes to upload the picture to your iPhone or iPod touch. To prevent this, email yourself the picture image and save it from the Mail application on your iPhone or iPod touch. That will ensure that the picture isn't enlarged and will show up in the correct size when used for signatures.
