A newsletter is an email sent regularly to subscribers. It often includes news, articles, and information about offers or events.

What belongs in a newsletter issue?
A recognizable sender and clear subject help readers identify the message. Put the most important information near the start. If you want readers to take an action, use a descriptive link. An easy-to-find unsubscribe link helps readers change their preference.
Example of a monthly issue
A cultural association sends a monthly newsletter with two event recommendations. The subject names the month. Dates appear as readable text in the email, and each item has a descriptive link to the event. The association also offers a web version and a plain-text version.
How can you interpret the response?
Clicks and unsubscribes can indicate how recipients respond to a newsletter. Open rates are estimates. Privacy features, for example, can preload tracking pixels.
