OptiKratos Email vs Sendlens

OptiKratos Email Analytics reports campaign engagement and how it relates to CRM deals and revenue. For each campaign, it tracks real-time opens, clicks, click-through rates, bounces and unsubscribes. Revenue attribution connects engagement to CRM deals and displays pipeline stage and revenue contribution; contact records can show a timeline of emails received, opened or clicked. Users can compare campaigns across segments and send times, and review deliverability measures including bounce rates, spam complaints and list health. A custom report builder combines selected metrics, though advanced features such as this may change during beta. The product page describes Email as unified with CRM and WhatsApp; the marketplace lists Mailchimp, Zapier and Make integrations. OptiKratos is cloud SaaS only, with no on-premise or self-hosted edition. A free tier includes 15,000 emails per month. Paid plans start at $41/user/mo billed annually, and a 14-day trial is listed. The service is available through API and web.

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.
