Sendlens review
A focused analytics layer for comparing campaigns, flows, conversions, and revenue.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sendlens is a hosted email marketing analytics platform for email marketers, SME marketing managers, and freelance or agency operators. It connects with email service providers, normalizes campaign data, fingerprints email content across 15+ structured fields, and groups campaigns into comparable clusters. Teams can analyze opens, clicks, CTOR, conversions, revenue, automation flows, and performance trends over time through a web application.
Pricing is organized around usage and analysis depth. The Free plan costs €0 and includes unlimited campaign sync and clusters, 10 fingerprint credits, and no credit card requirement. Essentials costs €29 per month with monthly billing and adds 50 fingerprint credits per month, auto-fingerprinting on sync, CSV exports, and email support. Pro costs €69 per month and includes everything in Essentials, 250 fingerprint credits per month, conversion attribution, revenue per campaign and cluster, and priority support. The published plans also indicate a yearly option with a 20% reduction.
Sendlens fits teams that need structured comparisons rather than only the reporting available inside an email service provider. ActiveCampaign and Brevo are supported integrations, while CSV exports can support downstream analysis in Sheets, Looker, and Power BI. Automation-flow and per-step analysis, configurable conversion attribution, pattern discovery, and trend reporting extend the product beyond basic campaign dashboards. It is a sensible choice for comparative campaign intelligence and attribution-focused reporting, but teams needing a wider integration ecosystem, a non-web deployment, or multi-touch attribution should consider a different analytics platform.
