Another element to consider is a pre-populated message that pulls into WhatsApp when your user clicks on your wa.me link.
It's very easy to manually create and customise wa.me links. There are three parts to consider:
The standard part: https://wa.me/
Your phone number with your country code but no plus (+) sign: 16506001008
(Optional) The text you want to show when a user clicks the link: ?text=your%20text
To customise your link, all you need to do is add the text in the correct format.
Take a look at this example: https://wa.me/16506001008?text=hi
The “text=hi” at the end of the link represents your pre-populated message. The word “hi” will automatically appear in the WhatsApp text field when your user opens the link.
