Hello @user519949 ,
When inserting a website link into an email in either text, image, or button format, you'll want to make sure you have the full URL, which includes the http:// or https:// and the www. bits as well.
You can simply copy the link to the website and paste it into an email and then you look down left. There was an option of making a clickable link. Then You can simply send your link. I also send different URLs of my vaping website to people.
