A few options.
1. Create a new mail to the sender with subject and recipient set up. Save and close. It will now be in your Drafts folder. Use cut and paste to create multiple copies of that email, so you have several in your Drafts folder. You can then use one up each time you send the email.
2. Create a little web page, which contains a "mailto:" link, that incorporates subject and recipient.
3. Create a macro that sends the email; then create a button on your toolbar to run the macro.
