Email is a message sent between mail systems that people use for communication, updates, and tasks such as account recovery. Product email design considers content, accessibility, privacy, delivery, and the action a message enables.
A letter must reach the right person, make its purpose clear, and contain enough information to act. A product email has the same responsibilities in a digital channel.
Make purpose and sender clear
Use a recognizable sender and a subject line that describes the message honestly. Put the most useful information first and write a concise body with a clear next step. Distinguish service messages needed for an account from optional marketing communication, and respect the person’s communication preferences.
Design for varied inboxes and access needs
Email clients render layouts differently, so use resilient structure and test common screen sizes. Keep text readable, links descriptive, and controls usable without relying on images. Provide alt text for informative images and preserve meaning when images are blocked or a person uses assistive technology.
Protect private information
Send only what the recipient needs and avoid exposing sensitive details in subject lines or links. Use secure, expiring flows for account actions and make destinations recognizable. Verify that messages go to the intended address and do not reveal another account’s activity through shared devices or forwarded mail.
Measure delivery and recover from failure
Track appropriate delivery and engagement signals, but do not mistake an opened message for a successful user outcome. Handle bounces, delays, and repeated sends carefully. If an email enables a critical action, provide an in-product recovery path and make the underlying process safe to retry.
