Best Email Audit Tools Compared

What is an Email Marketing Audit?

An email marketing audit is a comprehensive evaluation of your email strategy, including the resources and processes that support it. The primary goal is to identify areas for improvement, assess campaign performance, and optimize overall email marketing efforts. Conducting an audit helps ensure your emails reach inboxes rather than spam folders while providing valuable insights to enhance deliverability, engagement, and conversion rates.

In today’s crowded digital landscape, an email marketing audit is essential. It helps uncover strengths and weaknesses in your approach, allowing you to boost open rates, improve click-through rates, and reduce spam complaints. Data-driven insights from an audit can refine your strategy and improve your business outcomes.

Why Email Audits Matter More Than Ever

Email marketing is a powerhouse for businesses, but are your emails truly effective? Inboxes are more crowded than ever, standing out requires more than good content. Spam filters are smarter, and without regular audits, you could be missing valuable engagement opportunities. A comprehensive email audit optimizes deliverability, subject lines, engagement metrics, and email authentication, ensuring your campaigns perform at their best.

We compared five top email audit tools—Email Audit Engine, Postmastery Email Auditor, Mayple’s Email Audit Tool, FulcrumTech’s Email Audit Program, and InboxArmy’s Email Marketing Audit—to see how they stack up. One of these stands out as the best choice for Mailchimp users, but let’s dive in and see what each platform offers.

Types of Email Audits

There are several types of email audits, each focusing on different aspects of your email marketing efforts. Understanding these types helps you choose the right audit for your needs.

Email Marketing Performance Audit

This audit evaluates key performance indicators (KPIs) such as open rates, click-through rates, conversion rates, and unsubscribe rates. By analyzing these metrics, businesses can identify trends, pinpoint areas for improvement, and optimize campaigns for better results.

Email Deliverability Audit

An email deliverability audit ensures your emails reach recipients' inboxes rather than being flagged as spam. It evaluates delivery rates, sender reputation, email authentication, and content issues. Addressing these factors improves your deliverability and ensures your messages reach your audience.

How Do These Email Audit Platforms Compare?

Email Audit Engine: Best for Platform-Specific Insights

If you use Mailchimp, Email Audit Engine is the top choice. Designed specifically for Mailchimp users, it delivers insights that general audit tools can’t match. It identifies deliverability issues, engagement trends, and areas for improvement while providing clear, actionable recommendations.

One standout feature is its ongoing tracking, not just a one-time audit. As email marketing evolves, having a tool that adapts to new trends ensures your campaigns stay optimized. It assesses compliance, code and design elements, and automation reports to help improve strategy.

Postmastery Email Auditor: Best for Deliverability Experts

If your priority is ensuring emails reach inboxes, Postmastery is a solid choice. It focuses on diagnosing spam triggers, IP reputation issues, and authentication failures. With detailed SMTP and email header analysis, it’s an excellent resource for technical teams looking to improve domain reputation and avoid spam complaints.

However, Postmastery primarily focuses on backend deliverability. If you need insights on content optimization or audience engagement, you may need an additional tool.

Mayple’s Email Audit Tool: Best for Quick, Automated Insights

Mayple offers an automated audit that generates a report in minutes, evaluating over 50 key factors. It’s ideal for eCommerce brands looking for quick recommendations without manual analysis.

While useful for a fast health check, it lacks the depth of analysis some other tools provide. If you need personalized recommendations, this tool might feel limiting.

FulcrumTech’s Email Audit Program: Best for Comprehensive Strategy Audits

FulcrumTech provides a deep dive into your overall email strategy, including design, messaging, and performance. Their program is highly customized, delivering insights tailored to business goals and ensuring consistent branding across multiple platforms.

The downside? It requires significant input from your team and comes at a higher cost. However, if you’re looking for a full-scale strategy overhaul, it’s worth the investment.

InboxArmy’s Email Marketing Audit: Best for Full-Service Optimization

InboxArmy goes beyond analysis—it helps execute improvements. Covering list management, compliance, design, automation, and deliverability, this tool provides hands-on support to implement changes.

For companies needing more than just insights, InboxArmy is ideal. However, for businesses only requiring a one-time technical audit, it might be more than necessary.

How to Conduct an Email Marketing Audit

Define Your Goals and Objectives

Before starting an audit, determine what you want to achieve with your email campaigns. Identify key performance indicators to measure success, such as:

• Improving email deliverability rates
• Increasing open and click-through rates
• Enhancing conversion rates
• Reducing spam complaints and unsubscribes

Defining your goals ensures your audit provides actionable insights that align with your marketing objectives.

What Email Audit Platform Should You Use?

Choosing the right email audit platform depends on your specific needs:

• For Mailchimp users: Email Audit Engine is the best choice.
• For deliverability concerns: Postmastery provides deep insights.
• For quick, automated insights: Mayple is a great option.
• For a comprehensive strategy overhaul: FulcrumTech is ideal.
• For hands-on implementation: InboxArmy offers full-service support.

It’s also important to consider whether you need a one-time audit or ongoing tracking. While Mayple and Postmastery provide quick insights, Email Audit Engine and FulcrumTech offer long-term solutions. If you need full-service implementation, InboxArmy ensures continuous improvement.

The Verdict: Which Tool Should You Choose?

If you rely on Mailchimp, Email Audit Engine is the clear winner. No other platform offers such deep insights tailored to Mailchimp’s system. For broader audits, the right choice depends on your goals. Postmastery is ideal for technical deliverability fixes, Mayple for quick insights, FulcrumTech for strategy overhauls, and InboxArmy for full-service optimization.
