Sendlens

Sendlens is an email marketing analytics platform that unifies every email service provider into one dataset and surfaces the patterns behind your best-performing sends.

Connect ActiveCampaign, Brevo, or any combination of ESPs and Sendlens imports every broadcast, automation step, and recipient-level event, normalized for like-for-like comparison across tools.

Every email is automatically fingerprinted across subject-line style, body length, CTA placement, offer framing, and layout, then auto-clustered into meaningful peer groups. No tag taxonomy to maintain, no SQL, no CSV exports.

The pattern discovery engine tells you which creative structures drive opens, which CTAs drive clicks, and which flows drive revenue, so you ship the next campaign with evidence instead of a gut feeling. Conversion attribution ties each send to downstream revenue per campaign, cluster, and flow step.

Built for ecommerce brands, creative agencies, media companies, and consultants who take email seriously and are tired of ESP reporting that stops at opens and clicks. Sendlens fills the analytics gap sending tools were never designed to solve.
