Geysera turns anonymous visitors into revenue with automated first-party email campaigns for e-commerce and B2B brands.
Most online stores lose 88% of visitors before they buy. Geysera identifies these anonymous visitors, matches them to your first-party customer data, and launches targeted cart abandonment, browse abandonment, and winback email campaigns — all on autopilot.
What makes Geysera different:
- Integrates with Klaviyo, Mailchimp, and SendGrid — use your existing email infrastructure
- Always-on holdout testing measures the true incremental revenue of every campaign
- Performance-based pricing — you only pay for proven revenue Geysera generates
- AI-powered email content with customizable offer guardrails so discounts stay within your margins
- White-labeled reporting and dashboards your team can trust
No phantom revenue. No rented data. Just holdout-tested results that recover lost revenue and grow customer lifetime value.
