Frequently Asked Questions

What is a good email open rate for e-commerce in 2024?

E-commerce open rates between 26-32% fall within industry averages, with 26.64% representing the baseline and 31.08% showing above-average performance. However, specific segments like abandoned cart emails achieve 50.50% open rates, demonstrating that campaign type and audience segmentation dramatically impact performance. Brands should benchmark against their own historical data while working to exceed industry averages through inbox placement optimization, personalization, and content improvements.

How does Gmail's Promotions tab affect email open rates?

Emails landing in Gmail's Promotions tab experience significantly reduced visibility compared to Primary inbox placement. Research shows 21% higher open rates for emails reaching Primary inbox, directly impacting revenue for e-commerce brands. The visibility penalty compounds as lower engagement signals further damage sender reputation and future deliverability. Traditional approaches requiring content modifications force brands to compromise promotional messaging effectiveness, while solutions like Mailmend move emails to Primary inbox without content changes.

What's the difference between open rate and click-to-open rate?

Open rate measures the percentage of delivered emails that recipients open, while click-to-open rate (CTOR) reveals what percentage of openers clicked through. The average CTOR of 5.63% isolates content effectiveness from deliverability factors. Open rates reflect subject line appeal and inbox placement, whereas CTOR measures post-open engagement quality. Together, these metrics diagnose whether problems stem from inbox visibility issues or content relevance gaps.

How can I improve my email deliverability and open rates without changing content?

Mailmend's inbox placement technology specifically addresses this challenge by moving promotional emails from Gmail's Promotions tab to Primary inbox without requiring content modifications. The solution uses proprietary AI to analyze promotional threshold factors and generate custom code for Klaviyo accounts, delivering measurable improvements within 24 hours. This approach enables brands to maintain conversion-optimized messaging while achieving Primary inbox placement—eliminating the traditional tradeoff between deliverability and promotional effectiveness.

What email deliverability tools should I use to monitor open rates?

Effective deliverability monitoring requires tools that track inbox placement rates, tab categorization patterns, spam complaint rates, and engagement metrics across providers. However, monitoring alone doesn't fix underlying placement issues. Mailmend provides monitoring and optimization, enabling A/B testing within Klaviyo to measure exact performance differences between Primary and Promotions tab placement. This integrated approach combines visibility into problems with proven solutions that deliver Day 1 revenue impact.
