A mailto link is a controversial one, especially in email marketing – but we all have used it and will use it even though we know that it is not 100% bulletproof or that it can’t be tracked (some things are out of our control…).
I sometimes get asked to edit the link with not only adding a subject line but also including a pre-written body copy in that email reply. So, I’ll put it out there for all who may need it.
To add a subject line to a mailto link in HTML add in the ?subject=your subject
Please email me at ?subject=This is my subject line”>firstname.lastname@example.org
I also find %20 being used for spaces too.
Please email me at email@example.com
Now, a step further – let’s add some body text here by adding &body=
Please email me at %20is%20my%20subject%20line&body=Thank%20you”>firstname.lastname@example.org
Also, use the HTML code for ampersand, question mark, equal signs, double quotes – otherwise you might break the code.
A useful tip: I use %0D%0A to add in a paragraph break in the body copy.
