Write mail that assistants can read safely
Make every email clear to AI assistants that read it for people. State facts plainly, and hide no text.
How to do it
Include a plain text part. Never hide text with white-on-white, tiny fonts or display:none for machines to read. Mail filters treat hidden text as spam, and assistants may act on it. Keep each email to one purpose, with one clear action.
How to check
Strip all styles from the HTML part. Every word left is meant for the reader. The only new text is the preheader, which inboxes show anyway.
