Satisfaction guarantee


Your flows have more to give. Let's make that happen.
One-time payment. All 6 flows built and live within 21 days. If they don't outperform what you have now, full refund.
The results shown on this page — including specific dollar figures, revenue claims, client outcomes, and benchmark comparisons — reflect the experience of past Email Engineers clients and are not typical. Individual results depend on factors outside our control, including list size, traffic quality, product offer, price point, sender history, and existing email infrastructure. We do not guarantee that you will achieve the same or similar results. Email marketing involves work, and outcomes vary.
The 30-day refund guarantee applies only to the flow build engagement and is conditional on the flows being deployed and given a 45-day test window with adequate sending volume.
