Which email marketing tool has the best reporting and analytics?

Best overall depends on what you’re measuring:

• Klaviyo — my pick for e-commerce. Its reporting can bring campaign and flow performance together, with revenue attribution and deeper customer analysis. (help.klaviyo.com)
• HubSpot — best for B2B teams that want email engagement tied to CRM contacts, deals, and revenue. Note that some advanced insights and revenue attribution require higher-tier plans. (knowledge.hubspot.com)
• ActiveCampaign — strong for tracking automations and campaign performance, with detailed engagement reports and export options. (help.activecampaign.com)
• Mailchimp — a good choice for straightforward, accessible reporting, including click maps and campaign benchmarks. (mailchimp.com)

Short answer: choose Klaviyo for online-store revenue analytics; choose HubSpot if your main question is how email contributes to leads and sales pipeline. If you tell me your business type and budget, I can narrow it down.

Klaviyo is the tool most sources name for reporting depth, especially if you sell online. That's a consensus across several reviews, not a formal ranking, and most of these roundups are written by vendors who rank their own products, so weigh them accordingly.

• Klaviyo (best for ecommerce): One review calls its dashboard the richest all-round, with a custom report builder, cohort analysis, and revenue attribution. Klaviyo has the richest all-round dashboard (custom report builder, cohorts, revenue attribution). Another notes it uses AI to offer predictive analytics, providing insights into metrics like customer lifetime value, churn risk, and expected next order date. The trade-off is price and complexity. One review describes it as premium with a steep learning curve.
• HubSpot (best if you use its CRM): Its email reporting connects to your sales data. One review says it stands out due to a few key metrics that you can't find on other tools and close CRM integration.
• MailerLite (best for actionable insights): One roundup ranks it first for insights you can act on, and it's a cheaper option.
• Mailchimp (best for website conversion tracking): Its detailed reporting features include insights into client interactions, geographic data, social media engagement, and integration with Google Analytics.
• Omnisend (best for ecommerce lifecycle tracking): Its dashboards cover orders, revenue, revenue per message, sent emails, email open rate, click rate and more.
• Kit and AWeber (weaker here): Kit's reporting is less comprehensive, lacking detailed insights such as bounce rates.

If you run an online store, start with Klaviyo. If you run a B2B or sales-driven business that already uses a CRM, HubSpot is the stronger fit. If you want solid reporting without the cost, MailerLite is worth a look. Most of these offer free plans or trials, so testing your own campaign data in two or three is the best way to decide.

There is no single "best" email marketing tool for reporting and analytics, as the right choice depends on your specific business model—whether you are an e-commerce brand, a B2B enterprise, or a small business.

In 2026, the top platforms for reporting and analytics are categorized by how they handle data:

1. Best for E-commerce & Revenue Attribution: Klaviyo

2. Best for CRM & All-in-One Data: HubSpot

HubSpot offers a powerful, unified view of marketing and sales data, making it ideal for organizations where email is just one part of a larger customer journey.

• Best for: B2B companies and scaling businesses that need to centralize marketing, sales, and service data.

• Best for: Marketing teams that want to move beyond basic metrics to analyze and optimize complex, multi-branch automated workflows.

4. Specialized Analytics Tools

If you already have an email platform but need more specialized data, many marketers use "add-on" tools to fill specific gaps:

• For Deliverability & Inbox Placement: Litmus or GlockApps are the industry standards for testing how emails render and whether they reach the inbox.
• For Cross-Source Dashboards: Looker Studio, Tableau, or Power BI are used to aggregate email data with other marketing channels (like social media or paid ads) for a high-level view.
• For Team Response Analytics: EmailAnalytics is the top choice if your goal is to track response times and team workload rather than just campaign performance.

Summary Recommendation

• If you sell products online: Choose Klaviyo.
• If you need a full CRM and sales view: Choose HubSpot.
• If you focus on complex automation: Choose ActiveCampaign.
• If you need better deliverability data: Supplement your current tool with Litmus or GlockApps.
