How do I add a Like button is on the actual email that I send, and clicking it leads to a landing page on my website?
That means I want to add a Like button with HTML email newsletter that I send. And if anyone like it after that, I want to redirect them to my site.
You can not do this – “like” buttons can only be attached to URL’s. If you have a URL that somehow represents that specific email message then you might be able to get away with that.
Another thing to note is that not all email clients allow (by default) HTML content in the body of the email message – especially not iFrames…
What you might want to do is simply place a link to your website inside the email message and once the user lands on your website he/she can decide whether or not they want to “like” your URL.
