Making html mails in Mail

Apple removed the stationery feature from Apple Mail back in macOS Mojave. It has not been replaced, and since you are unlikely to know if all Mail recipients can or wish to accept Rich text email, you should consider hosting your newsletter on a website and send the link to those that wish to read it.

I second VikingOSX's suggestion.

Alternatively, you could compose your newsletter and send it out as a pdf attachment.

FWIW at work I disliked when some trivial announcements containing a few trivial words were sent as .pdf attachments when an inline (maybe styled) text would have done the same thing without the recipient having to open the ** attachment /rant ;-]

I much prefer plain text e-mail. I never ever compose a rich text one.

I would not suggest using a pdf for the use case you describe, either.

But a newsletter is a different thing, it may contain styled text, images, etc. A pdf seems the most appropriate IMHO.

Perhaps not as severe as mandatory work email subscriptions where there were far too many Reply ALL Dumba..es causing over 500 new emails per week…

You are welcome.
