In practice
Keep it short and plain text-friendly. Avoid large images and long legal text, which add size and can look like clutter. A signature identifies a person; the footer of a marketing email identifies the company and carries opt-out details.
Verification and sending
Signatures often contain addresses and phone numbers, which is where harvesting tools find them. Treat them as source data to verify, not as confirmed contacts.
