Help ensure your emails
hit the inbox
Stop guessing why your messages end up in spam. Follow this 26-point checklist to achieve technical compliance, enhanced sender reputation, and delivery success.
Unsubscribe
Always include a clear and easy-to-use unsubscribe option in the body of your emails. The process should require no more than a single click, without forcing the recipient to log in or provide extra details. Making it simple to opt out not only builds trust but also reduces the chance of recipients marking your messages as spam.
In addition, add a List-Unsubscribe header to your emails. This enables mail clients to display a built-in unsubscribe link, which many recipients find more convenient.
Ensuring both methods are available helps maintain compliance with regulations (like CAN-SPAM, GDPR, and similar laws) and demonstrates respect for subscriber choice.
It's also best practice to process unsubscribe requests immediately — or at least within the legally required timeframe — and to provide confirmation that the request was successful. You should never attempt to hide or discourage the unsubscribe process, as doing so damages trust and increases the risk of complaints or blacklisting.
