Understanding Email Deliverability

Email deliverability is a crucial aspect of any successful email marketing campaign. It refers to the ability of your emails to reach your subscribers’ inboxes without being blocked or filtered as spam. Understanding how deliverability works can help you optimize your email strategy and improve the chances of reaching your audience.

Here are some key factors that affect email deliverability:

  1. Sender Reputation: Internet Service Providers (ISPs) evaluate the reputation of senders based on various metrics like engagement rates, complaint rates, and bounce rates. Maintaining a good sender reputation is essential for high deliverability.
  2. Authentication: Implementing authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) verifies that you are an authorized sender.
  3. List Quality: Keeping a clean and engaged subscriber list helps improve deliverability. Regularly remove inactive or unengaged subscribers, as they can negatively impact your sender reputation.
  4. Content Relevance: Emails that contain relevant content tailored to recipients are more likely to avoid spam filters and land in their inbox.
  5. Avoiding Spam Triggers: Certain words, phrases, or practices may trigger spam filters and decrease deliverability. Avoid using excessive punctuation marks (!!!) or misleading subject lines.
  6. Consistency: Sending emails consistently at regular intervals establishes trust with ISPs over time.

To monitor and improve your email deliverability rate, consider these best practices:

  • Use reputable Email Service Providers (ESPs) like Klaviyo that prioritize deliverability.
  • Monitor delivery statistics such as open rates, click-through rates, bounces, complaints, etc., provided by ESPs for insights into performance.
  • Keep track of blacklists: Check if your domain or IP address has been added to any blacklists which may hinder delivery.

Remember that maintaining good email deliverability requires ongoing effort. By understanding the factors that influence it and following best practices, you can increase the chances of your emails reaching your subscribers’ inboxes effectively.
