Keep the purpose of a message focused
If a sentence on a page is unclear, that sentence and your question may be enough. Sending a full identity document, account history or financial record can disclose information unrelated to the question.
Before attaching an image, check surrounding notifications, other conversations and personal names as well as the central area. Crop to the relevant section and conceal sensitive information where needed.
Corrections and control of your own copies
To request a correction, explanation of use or deletion concerning an earlier email, identify its subject and approximate sending time. Do not resend the same secret information merely to explain your request.
A copy of your sent message may remain with your own email provider. Manage its retention, deletion and shared-device access through that provider's settings; this page does not replace those controls.
