Master Your Email Campaigns: Complete Guide to Email Deliverability Audit

With email marketing being an essential aspect of today’s digital world, its efficiency relies heavily on effective email deliverability. Email deliverability audit is a thorough examination of your email marketing program’s performance and measures to ensure your emails reach their intended recipients. The importance of this audit can never be overstated, considering its significant impact on your organization’s reputation and bottom line.

Understanding Email Deliverability and Its Importance

Email deliverability refers to the ability of your emails to land in the inbox of your recipients rather than being filtered out or marked as spam. It is crucial to understand that higher email deliverability rates ensure recipients see and interact with your content.

Poor email deliverability impacts your email marketing campaigns in several ways:

  • Reduced engagement rates: Your emails are less likely to be opened and clicked by recipients.
  • Damaged sender reputation: Internet Service Providers (ISPs) will consider you an untrustworthy sender.
  • Lower ROI: Your email marketing efforts will yield disappointing results.

As a result, achieving a high deliverability rate should be a top priority for businesses looking to make the most out of their email marketing efforts.

The Need for an Email Deliverability Audit

An email deliverability audit helps businesses pinpoint the issues affecting their email program and devise remedial strategies. Audits are essential to:

  1. Uncover hidden issues: An audit will help you identify deliverability problems that may go unnoticed.
  2. Improve sender reputation: Resolving issues will enhance your standing with ISPs and recipients alike.
  3. Maintain healthy email list: Regular audits ensure a robust, engaged, and responsive email list.

Steps to Conduct an Email Deliverability Audit

Follow these steps to conduct a comprehensive email deliverability audit:

1. Reviewing Sender Reputation

Sender reputation refers to how ISPs perceive your email sending practices. A good reputation ensures better email deliverability. You can use sender score tools like or Google Postmaster Tools to gauge your standing with ISPs.

2. Analyzing Email List Quality

Perform a thorough analysis of your email list to identify inactive or disengaged subscribers. Proper list hygiene includes removing bounced addresses, dead domains, and blocking new invalid subscribers. List segmentation is also crucial and ensures a targeted and engaged audience for your campaigns.

3. Evaluating Performance Metrics

Examine key performance indicators (KPIs) like open rates, click-through rates (CTRs), bounce rates, complaint rates, and unsubscribe rates. These metrics provide valuable insights into the effectiveness of your campaigns.

4. Inspecting Technical Email Infrastructure

Technical elements like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records ensure the authenticity of your emails. Setting up these records correctly can dramatically improve your deliverability rate.

5. Examining Content and Design

Content quality and design play a crucial role in deliverability. Keep subject lines relevant, concise, and personalized. The body content should provide value and adhere to the CAN-SPAM and GDPR guidelines. Make sure email templates are mobile-friendly and thoroughly optimized.
