How to Add an Email Signature on Android

Your phone is where most of your emails get sent from, so your signature needs to look professional even on mobile. Many Android users skip signatures because they think it's too complicated, but it's actually straightforward once you know which app you're using and where to look.

Open the Gmail app on your Android phone and tap the three-line menu icon in the top left. Scroll down and select Settings, then choose your email account. Tap Signature and enter your signature text in the field that appears. You can add your name, job title, phone number, and company—whatever you want recipients to see at the bottom of your emails.

Once you've typed your signature, tap the back arrow to save it. From that point forward, every email you send will automatically include your signature at the bottom. If you manage multiple Gmail accounts, you can set a different signature for each one by repeating these steps for each account.

If you want to include a logo or profile photo, the basic Gmail signature editor won't let you embed images directly on Android. That's where an HTML email signature comes in handy—it's pre-formatted and works perfectly in Gmail with embedded images that won't break.

Launch the Outlook app and tap the three-line menu icon at the bottom left. Go to Settings and select your email account. Tap Signature and toggle the switch to turn it on. Type your signature information in the text field and tap Done.

Outlook for Android is straightforward, but it also doesn't support HTML formatting or embedded images in the mobile app. If you want a branded signature with your company logo, you'll need to use SignatureFox to generate an HTML file and then add it through Outlook's desktop settings, which will sync to your mobile app.

Text-based signatures are fine for simple contact info, but they don't show your professionalism or brand. HTML signatures can include logos, headshots, social media links, and formatted text—all embedded in the email itself so images never break.

The challenge with Android is that most mobile email apps have limited HTML support in their built-in signature editors. The workaround is to create your HTML signature using SignatureFox on a desktop, download the HTML file, and then add it through your desktop email client. Once it's added, your mobile apps will use the same signature you set on desktop.

SignatureFox generates table-based HTML that's compatible with Gmail, Outlook, Apple Mail, and other major email platforms. Your logo and headshots are embedded as base64, which means they stay embedded and never appear as broken image links. You'll get a professional signature that looks the same on Android, iPhone, desktop, and webmail.

Your email signature is the last thing someone reads before they decide whether to trust you or do business with you. A plain text signature with just your name tells people you either don't know how or don't care enough to look professional. A branded signature with your logo, title, and contact options shows you're serious and trustworthy.

This matters especially on Android because people assume mobile emails are less polished. A professional HTML signature proves otherwise. It shows you invested in your brand, and it gives recipients multiple ways to contact you—phone, email, website, LinkedIn.

You don't need design skills or HTML knowledge to create one. SignatureFox handles the technical side, and you just pick a template that matches your style.
