Pre-populate Subject field in hyperlink

In case it might help others, here is how I solved this easy peasy! In a blank Word document I typed the hyperlink I wanted & when you right click to add a hyperlink a menu opens with 3 tabs. The Email Address tab has 3 fields email address, SUBJECT & recent email addresses. Easy. When complete copy the whole thing into your email.

Hope this helps - its taken me hours of research to find it.

Thnx Bob. I have copied your instructions exactly but as in the past I don't get to OK my entry.

Here is my entry

<a href="mailto:tom299@me.com?subject=The%20SUBSCRIBE%20of%20the%20mail">Send mail with subject</a>

I do not get to OK this. If I remove everything except my email address the hyperlink works button course with a blank subject line. I have Message format set to Rich Text but I'm wondering if there is another setting I don't know about.

Researching in Communities I saw this post

In Apple Mail, what is called "rich text" is actually HTML. However, Apple Mail prefers to use plain text for compatibility. Unless you do something to make it think it needs HTML, you won't get it. What you usually have to do is change some part of the text to some non-default font or style. You have to do this in the message itself. The font settings in Preferences just change the default. You have to make something non-default to trigger HTML. One easy trick is to create a signature that has some styled text in. Then, any time you use that signature you will get an HTML message.

I wasn't saying your solution didn't work. When I click to create a hyperlink in Mail it would not allow me to insert your solution. As soon as I typed it in the OK greyed out. The only thing I could OK was my email, nothing else. I tried setting my prefs to plain text didn't work, set to Rich Text, didn't work.

Sounds like you're annoyed I used a simpler solution, but I got no help in solving how to use your solution so had to find one ASAP. Apologies if your offended especially since you were the only response.

I dont understand I'm afraid. I can only have Plain text or Rich text. I have no idea what it mean or how you would send an email with html.
