Mobile Email Signature: A Comprehensive Guide

What is the main purpose of a phone signature? It is to introduce yourself and your company and to remind your contact who you are. 

Using a professional mobile email signature in business correspondence will help you to:

• Establish trust and credibility
• Provide your recipient with multiple ways to connect with you
• Back up your name and brand with social proof
• Increase your business’ brand awareness
• Promote products or services
• Drive traffic to your company website

And many more things. It all really depends on how you use the potential of your mobile email signatures.

You might be among those many who use “sent from my mobile device,” which is a standard for people with portable devices. If you’re using a business phone system to send an SMS, you can edit your signature to make it custom to your brand messaging. The iconic “sent from my iPhone” has generated a lot of “sent from my iPhone” alternatives. There are device-specific sign-offs or system-specific ones:

• Sent from my Android phone
• Sent from my Samsung Galaxy smartphone
• Sent from Samsung Mobile
• Sent from my BlackBerry (remember those?)
• Sent from my Windows Phone
  and so on.

Regardless of the type of your phone, the general formula is:

Sent + from + (my) + [device name / OS]

People mostly use these types of signatures as an excuse for making typos and writing rather brief messages. Remember that they no longer validate your lack of attention or bad use of auto-correction. Here are the three main reasons why:

1. No one cares which phone you use

Initially, the iPhone signature was meant to tell the world that you have an iPhone. With various devices these days, you won’t surprise anyone by saying that you have one of those.

2. “Sent from my mobile device” is no excuse for your mistakes

It can be harder to avoid mistakes when writing from a phone versus from a desktop. Still, there is no need to mention this in your mobile signature. It’s always better to make sure your message is error-free.

3. It is not appropriate for business emails

A standard email signature on your mobile (funny or not) is inappropriate for business communication. It is merely a signoff that you can use for fun with your friends and personal contacts.

Change your default email signature to something more practical since we use our smartphones more frequently to communicate with our business contacts.

You need a presentable signature, just like the one you would typically have in the mail client on your computer at work. It should do the following:

• Tell who you are
• Provide your recipient with your contact details
• Communicate your company’s brand message
• Serve your company’s business goals

Let’s look at some smartphone signature design tips.

Tips for Creating a Mobile Email Signature Design

The first and foremost thing you should do is ensure you are building a mobile-friendly email signature. Think about what your contacts will see on their mobile devices. Remember that the phone screen is much smaller, while the space is limited. And don’t forget that mobile internet speed can be limited.

• Use vertical signature templates

Because a typical mobile screen is vertical, create email signatures in vertical layouts, too. Don’t fit everything into a single line. Break the information apart when possible. Highlight the main info in bold font. At the same time, make sure that you don’t have too many lines with text at the end of your email.

• Add your cell phone number

Including your mobile number when writing from your device is only logical. Make it easy for people to call you right away by tapping on the phone digits. To do this, you must create a hyperlink with “tel.:” followed by the number (no spaces).

• Add your email

Although we wrote before that adding an email address in the email signature often makes no sense, it does in reality, especially on mobile. First of all, you can expect your contact to click on it and be able to create a new message, especially when they want to start a new subject.

• Add larger social icons and stick to three

If you are linking to your social profiles, use social media buttons. Keep in mind that they must be big enough to be clickable. 

• Add a banner to the phone email signature

An email signature banner can be visually attractive and helpful for your business. You can use it with any content to advertise or promote just about anything, from an announcement of a new article or an invitation to connect at a tech conference.

• Use small images that could be uploaded using a cellular network

If you use images in your cell phone email signature, ensure their size is optimal for cellular networks but still has a good quality without visible pixels. 

• Delete green line messages

Some devices can color-highlight quoted messages (“green line messages”), which can be disabled in some email client settings. Also, you can ensure that your signature appears before the quoted messages in an email conversation.
