What it is

Sendlens is a web-based email campaign intelligence platform that analyzes performance beyond the reporting provided by email service providers. It captures campaign screenshots and scores them across more than 15 fields, including content, visuals, calls to action, layout, tone, palette, and spam signals. It relates those traits to open rate, open-to-click rate, and conversion data, then ranks patterns by statistical confidence. Similar campaigns can be clustered for comparison with aggregated metrics; users can rename, recolor, or manually assign campaigns. Automation emails are grouped under their parent flow with totals and per-step breakdowns. Conversion data can be uploaded as a CSV for attribution funnels, using a configurable seven-day default window; attribution is a Pro feature. ActiveCampaign and Brevo are live integrations, while Klaviyo, Mailchimp, and Kit are listed as coming next. Campaign and flow performance can be exported to CSV for use with Sheets, Looker, and PowerBI. The free plan includes ten one-time fingerprint credits. Essentials costs €29 a month, billed monthly; Pro costs €69 a month, billed monthly.
