The concept of email deliverability is crucial for businesses and marketers aiming to reach their audience effectively. It refers to the ability of an email to successfully reach the inbox, avoiding filters that categorize it as spam. A variety of factors influence this, and achieving optimal deliverability requires understanding and applying specific best practices.

Note: Email deliverability can impact engagement rates, brand reputation, and overall campaign performance.

One critical element in improving email deliverability is adhering to a structured "Deliverability Code," which involves several components that directly affect whether your messages land in the inbox or not.

  • Authentication Protocols: Ensure proper SPF, DKIM, and DMARC setup to confirm that your emails are legitimate.
  • IP Reputation: Maintain a good sender reputation by monitoring your sending IP’s score.
  • Content Quality: Avoid spammy phrases, poor formatting, and broken links in your email body.

Let’s break down some of the most important factors that influence this code:
