Improve email deliverability

A well-written email may still miss the main inbox. Several settings can affect delivery.

Use a consistent sender identity

Set a valid reply address and, when available, an authenticated sending domain.

Email an opted-in audience

Avoid purchased lists or addresses collected without permission. Make it easy for recipients to unsubscribe.

Keep your list in good shape

Remove or correct clearly invalid addresses, and monitor delivery errors.

Avoid misleading messages

Use a subject line that reflects the content, clear links, and a sender identity recipients can recognize.
