How to add font sizes 15 and 16 to Mail's font size dropdown?

Hello,

Short Answer, is you cannot. There is no way to add font sizes to the dropdown.

Long answer:

Depending on what macOS version you are running it may or may not be possible to set a custom font size.

If you tap on command+t to bring up the Font Palette it may let you type in the specific font size in the font drop down there. But it's hard to get it to respond, as it keeps focus on the email message and not the font palette.

I have been able to get it to respond by maximizing the font palette to full screen, then double clicking on the font size drop-down let's me type a blue in there. then you press the green bubble again to return to regular size and hit enter and any selected text will then change to the entered font size.

Not the easiest thing to do, but it works.

Alternatively, writing the email in a word process such as Pages or Word and the copying it into the mail message will preserve the fat size, and the word processor should offer the full range of font sizes.

I think Phil124 has provided good alternatives.

But I think you are over worrying this. The font displayed in the recipient's received email is under the control of the recipient. You have no control over what the recipient sees. If you want the recipient to see a specific font and size, compose the email in a word processor such as Word and attach the document to the email. The recipient will then open the attachment using Word and see the same font size you used to compose the attachment.

Many thanks for taking the time to provide such a detailed and comprehensive response to my questions. I really appreciate your effort and valuable insights!

This gives me all the information I need to move forward.

Thanks again for your support!

You're very welcome. Glad I could help.
