How to remove the signature line from your mobile device

Scott Lowe offers a quick tutorial on how to remove or alter the text from the signature line on your iPhone or Android device.

"Sent from my iPhone," "Sent from my Verizon Wireless Phone," and the like. You've probably seen these lines on countless messages as more people are staying tethered to their mobile devices and using them to send and respond to messages.

Since the percentage of people with these email-laden devices is increasing, mobile carriers and some device manufacturers are increasing the amount of free marketing that they receive by virtue of the fact that these settings are often the default on devices when they ship. Back when smartphones were the exception, I imagine that people touted their ownership with pride and didn't mind so much that the default tagline was there for all to see. However, as these devices become more pervasive, default signature lines end up doing nothing except tell the recipient that the person responded while on a smartphone.

That said, I personally use the signature line to help recipients understand that any "interesting" autocorrects that might be found in one of my messages are because I'm using a mobile device. However, rather than keeping the default signature, I've changed it to read "Sent from my mobile device - please excuse typos."  Now, of course, I keep audience in mind. If I'm sending something to someone sensitive, I reread and correct anything I might find -- but if I'm just responding to something quick, I'm in a hurry, and the other end just needs an answer and doesn't care if its pretty, this signature line is a perfect fit.

So, how do you go about modifying or removing the signature line from messages?


On your iOS-based device, go to Settings | Mail, Contacts, Calendars (as shown in Figure A) Figure A

Next, scroll down the page and locate the "Signature" item and tap it (Figure B). Figure B

Choose the Signature item
As shown below in Figure C, provide whatever text you'd like to appear when you send a message from the device. It should be noted that the signature is common to every account you have configured on the device. If you have multiple email accounts configured, they all use the same signature. Figure C

Provide a new signature

Now, the next time you send a message, the recipient will see your new signature.


The steps here will vary, depending on your Android device -- but the basic premise is the same. In this example, I'm following the procedure for a Droid X running Android 2.3.3 (Gingerbread). Go to the Email app, tap the Options button, and choose Messaging settings (Figure D). Figure D

Choose Messaging settings

On the Messaging settings page, choose the Email option.

Figure E

Choose Email to change your email settings
When you get to the Email settings page, choose the Compose options setting (as shown in Figure F). Figure F

Choose compose options

Finally, provide an email signature that makes sense for you or simply remove the default one.

Figure G

On the Compose options page, provide your new signature

As I mentioned above, the steps will vary for different Android devices. For example, if you have an HTC Incredible, go to the Mail app and then select the Menu | More | Setting |General Settings | Signature.

Go to Apps / select the account you want / click on "..." / click on settings / check Use an email signature / type in whatever account-specific message you want. I have four e-mail providers and use a different ssignature for each one! Dave


... that this was something so complicated that we need an article to tell us how to do it, and further, why we have a unique sig on our mobile devices. Isn't this all a little obvious?


This is a very content free article. There is nothing remotely interesting or worth reading here. On top of that the author suggests that it is OK to have some types because you are on a mobile device. Bulls..t! Typos are NEVER ok. If you cannot type on your phone then don't emails from it. If you want to send emails take the time to learn how to type use the built in spell checker. Typo's create a bad impression about you.


We have a few Androids that started showing up at the office, the problem I found that when a custom signature is added it looks normal to most recipients how ever will look real bad in a Gmail account. Anyone ever see this and is there a fix for this?


This is a very content-free comment, but amusing in its ironic incompetence: ..On top of that the author suggests.. (punctuation) Correct: On top of that, the author suggests.. is OK to have some types.. (typo) Correct is OK to have some typos.. ..Bulls..t! (weaselly) Correct: BS! ..Typos are NEVER ok. (yelling) Correct: ..are never OK. ..don't emails from it. (we wonts) Correct: ..don't email from it.. ..take the time to learn how to type use the built in spell checker.. (illiterate) Correct: ..take the time to learn how to type and use the built-in spell checker.. Plus inconsistency: ok and OK And finally: "Typo's create a bad impression about you." Well, you (almost) said it, and I agree: "Typos create a bad impression of you."


Full points for sarcasm, or is it irony? "it is OK to have some types" and "emails from it" cf the poem, " Eye halve a spell in checker"


Yes they do give a bad impression, as you clearly typed "...then don't emails from it."
