How do I add a clickable WhatsApp link to my Gmail or Outlook email signature?

Why a number alone is not enough

A number in a signature reads as a phone number. Some email apps turn it into a call link and some do not, and either way tapping it starts a phone call, not a WhatsApp chat. A reader who prefers to type has to save the number and then find it in WhatsApp. A wa.me link cuts that to one tap.

Step one: the link

1. Open the WhatsApp link generator and pick +971 or +966 in the country-code helper if your number is local.
2. Type your number, such as the example UAE number 050 123 4567, which becomes 971501234567.
3. Leave the message empty. Email readers already know why they are writing, and your signature goes on every email, on every topic.
4. Copy the link: https://wa.me/971501234567.

Step two: the signature

The Email signature builder has a 'Social links' section that takes up to six links, each with two fields: 'Shown as' and 'Link'. Put 'WhatsApp' in 'Shown as' and paste the wa.me link into 'Link'. The link starts with https, so the builder accepts it, and it appears in the signature as a clickable word next to your other links.

If you write the signature directly in Gmail's or Outlook's settings instead, type the words you want, select them, then use the insert-link button in the signature editor and paste the link. Button names and positions vary between versions, but 'visible text with a link behind it' works the same way in every email program.

Details that make the signature better

• Do not show the raw link as text in the signature; it looks technical. A clear word is tidier and easier to understand.
• If you add a pre-filled message, keep it general and short, such as 'Hello, about your email', because the signature appears on every email.
• Keep your ordinary phone number in the signature too, for people who prefer to call.
• Test by sending an email to yourself, opening it on your phone and tapping the WhatsApp word.

What about on a computer?

When a reader clicks the link on a computer, the browser opens a WhatsApp page, and what happens next depends on their device and whether WhatsApp is installed. That is outside the tool's job; it only builds the link. It is one more reason to keep the written phone number beside it.
