Your email signature is prime real estate. If someone reads your email, they trust you enough to consider a reply. Give them the fastest way to reply: WhatsApp.
Step 1: Generate the WhatsApp link
Use our free generator:
- Country + number.
- Pre-filled message like "Hi! Following up on your email."
- Copy the URL.
Step 2: Add to Gmail
- Open Gmail β Settings (gear icon) β See all settings.
- Scroll to Signature β create or edit your signature.
- Type "Chat on WhatsApp" or use the WhatsApp icon (see below).
- Highlight the text β click the link icon in the toolbar β paste the WhatsApp URL β OK.
- Scroll down β Save changes.
Send yourself a test email. Click the link. WhatsApp should open.
Step 3: Add to Outlook (New Outlook / Outlook Web)
- Click the gear icon β View all Outlook settings.
- Mail β Compose and reply β Email signature.
- Type your signature. Highlight "Chat on WhatsApp" β Insert link β paste URL β OK.
- Save.
For Outlook desktop (Windows): File β Options β Mail β Signatures β New. Same link-insertion process.
Step 4: Add to Apple Mail
- Mail β Settings β Signatures.
- Create a signature. Type your text.
- Select "Chat on WhatsApp" β Edit menu β Add Link β paste URL.
- Set as default for your account.
Step 5: Add to Apple Mail on iPhone
- Settings (iOS Settings, not the Mail app) β Mail β Signature.
- Add your text. You can't add a clickable link directly in iOS settings, but paste this HTML into a note first, then copy from note to signature β the link survives.
Design tips that increase clicks
- Use the WhatsApp icon (green speech bubble). Free icons: icons8.com/icons/whatsapp, flaticon.com.
- "Chat" > "Message" > "Contact" β "Chat" is the least corporate.
- Put it on its own line after your name/title. Buried in the middle, it gets skipped.
- Include hours if you're strict: "Chat on WhatsApp (9amβ6pm)" β sets expectations.
- Don't add three chat options (WhatsApp + Telegram + Signal + SMS). Pick one primary.

Common mistakes
- Raw
wa.me/12125551234as visible text. Ugly and long. Hyperlink it behind clean text like "Chat on WhatsApp." - No pre-filled message. Opens an empty chat, awkward.
- Broken link because someone stripped tracking parameters. Test after every signature change.
- Blue-and-underlined link in a WhatsApp-branded green world. Style the link to match your brand.
Measure it
Add a UTM parameter to distinguish email-signature chats from web-form chats:
https://wa.me/972541234567?text=Hi!%20from%20email%20&utm_source=email_signature
The UTM survives in the pre-filled message so you can see the source in your WhatsApp inbox. Review monthly: how many chats came from email signatures vs. other sources? If it's the top source, redesign the signature to feature WhatsApp even more prominently.
