https://sendlens.com/blog/ Notes from the Sendlens team on email analytics, campaign intelligence, and the ESPs we all work inside of. en-us Wed, 03 Jun 2026 18:38:59 GMT https://sendlens.com/blog/email-benchmarks-compare-yourself-to-yourself/ https://sendlens.com/blog/email-benchmarks-compare-yourself-to-yourself/ Industry email benchmarks tell you where the average sender sits, not whether your last campaign was any good. For opens, clicks, and conversions, the only honest comparison is you against you. Here's why, and how to run it. Landscape Thierry from Sendlens Wed, 03 Jun 2026 00:00:00 GMT https://sendlens.com/blog/activecampaign-reporting-limitations-2026/ https://sendlens.com/blog/activecampaign-reporting-limitations-2026/ ActiveCampaign is a strong sender. But once operators get past the basic campaign report, five specific gaps keep showing up in our calls — and each one has the same shape: the answer lives outside the ESP. Comparison Thierry from Sendlens Tue, 14 Apr 2026 00:00:00 GMT https://sendlens.com/blog/newsletter-vs-promotional-email-benchmarks/ https://sendlens.com/blog/newsletter-vs-promotional-email-benchmarks/ The single most common mistake we see in email analytics is comparing a newsletter to a flash sale and treating the gap as performance. Clusters fix the apples-to-apples problem without asking marketers to redo their taxonomy by hand. Product Thierry from Sendlens Tue, 31 Mar 2026 00:00:00 GMT https://sendlens.com/blog/email-marketing-analytics-gap/ https://sendlens.com/blog/email-marketing-analytics-gap/ Email platforms are very good at sending email. They're less good at telling you why one email outperformed another. That isn't an accident — it's a consequence of what they were built for. Landscape Thierry from Sendlens Tue, 17 Mar 2026 00:00:00 GMT https://sendlens.com/blog/email-automation-flow-analytics/ https://sendlens.com/blog/email-automation-flow-analytics/ Most analytics treat the emails in an onboarding flow as independent campaigns. That's the wrong unit of analysis — and it hides the one question automation teams actually need answered.

It also quietly rewards noise as if it were insight. Here's why most email A/B tests teach almost nothing — and what actually produces learning.
