How to add an email signature to Outlook for Android
The Outlook mobile app for Android supports a single, plain-text signature and does not render HTML, logos, or images. You can still add your key details as text so replies sent from your phone stay professional.
Create your signature first →- 1
Open the Outlook app and tap your account avatar in the top-left corner.
- 2
Tap the Settings gear icon at the bottom-left of the menu.
- 3
Under the Mail section, tap Signature.
- 4
Delete the default "Get Outlook for Android" text.
- 5
Type or paste your details as plain text — name, title, phone, and website.
- 6
Tap the checkmark or back arrow to save.
💡 Outlook for Android is plain-text only, so pasting a formatted Sigmint signature will flatten it to text and drop all logos, colors, and image links. Keep a clean text version for mobile and use your full HTML design on desktop.
