DELIVERABILITY

Content is only one part of email delivery

Configure SPF, DKIM, and DMARC correctly.

Send only to recipients who expect your messages.

Keep bounce, complaint, and unsubscribe rates under control.

Use a clear and functional unsubscribe process for marketing email.

Maintain a healthy sending domain and IP reputation.

Avoid misleading subjects, deceptive links, and excessive formatting.

Keep HTML valid and provide useful readable content.

Test important campaigns across your actual recipient providers.

IMPORTANT

A content score cannot predict inbox placement

Modern mail providers evaluate many signals beyond message text, including sender reputation, authentication, engagement, complaint history, sending patterns, recipient behavior, infrastructure, links, and provider-specific filtering systems. Use this score as a content review tool, not as a guarantee that an email will reach the inbox or spam folder.
