WhatsApp & Mailto Link Generator

How do I create a WhatsApp click-to-chat link or a mailto email link?

Short answer: We.Inc's free WhatsApp & Mailto Link Generator creates a WhatsApp click-to-chat link with your number and a pre-typed message, and a mailto link with the address, subject, and body already filled in. It also removes spaces, brackets, and leading zeros from phone numbers and encodes special characters so links do not break.

Key facts

  • A wa.me link is WhatsApp's official click-to-chat address, formed as https://wa.me/ followed by a full international number with no plus, spaces, or dashes.
  • Adding ?text= to a wa.me link pre-fills a message in the chat.
  • A visitor does not need to save your number to use a click-to-chat link.
  • WhatsApp numbers need the full international format, and a leading 0 from a local number should be dropped.
  • In a mailto link, multiple email addresses are separated by commas and parameters are joined with an ampersand.

Make two kinds of contact links on one page: a WhatsApp click-to-chat link that opens a chat with your number and a ready-typed message, and a mailto link that opens a new email with the address, subject and body already filled in.

How it works

  1. For WhatsApp, pick your country code, enter your number and an optional greeting message. The tool removes spaces, brackets and leading zeros for you.
  2. For email, enter the address, and optionally a subject, body, CC and BCC. Special characters are encoded so the link does not break.
  3. Copy the plain link, or copy a ready-made HTML button for your website.
  4. Click 'Test' to try the link before you share it.

Where to use click-to-chat and email links

On a website, put the WhatsApp link on a clear button near your phone number, especially on mobile where customers are already holding the device they chat on. It is also useful in Instagram and Facebook bios, Google Business Profile, flyers (as a QR code) and email signatures.

Mailto links suit 'Email us' buttons, quote requests where you want a consistent subject line, and internal links like 'Report a problem with this page' where a pre-filled subject saves you sorting mail later.

Formatting rules that trip people up

For WhatsApp: use only digits, include the country code, and remove the trunk zero that many countries put in front of local numbers. The message must be URL encoded; this tool does it for you, including line breaks and emoji.

For mailto: separate multiple addresses with commas, encode everything after the question mark, and join parameters with &. A single unencoded & or # inside the subject will silently cut it short, which is why generating the link is safer than typing it.

If you are building a site with We.Inc, you can paste either link into a button, or simply ask the builder to add a WhatsApp button with your number.

Tips

Frequently asked questions

What is a wa.me link?

WhatsApp's official click-to-chat address. https://wa.me/ followed by a full international number (no plus, spaces or dashes) opens a chat with that number, and ?text= adds a pre-filled message.

Does the person need to save my number?

No. That is the point of click-to-chat: the visitor taps the link and the chat opens without saving a contact.

Why does my number need the country code?

WhatsApp needs the full international format to know which country the number is in. Drop the leading 0 from a local number: UK 07700 900123 becomes 447700900123.

What is a mailto link?

A link starting with mailto: that opens the visitor's email program with a new message. You can add subject, body, cc and bcc as parameters, which must be URL encoded (spaces become %20).

Do mailto links cause spam?

Any email address shown on a public page can be collected by spam bots, whether it is a link or plain text. Good spam filtering on your inbox matters more than hiding the address.
