No signup. No build step. The link works immediately.
Your HTML is hosted exactly as you wrote it — nothing is rewritten or restyled.
Send HTML as an attachment and the other person has to download it, find it, and double-click it — which often just fails on a phone, or renders with the styling gone. Worse, fixing one typo means sending the whole thing again, and now three versions sit in their inbox with no clue which is current. With a link, they click and it is a web page. You edit the content, and the same link is already correct.
Just want a link fast? Try HTML to URL — that page is shorter: drop and go.
