Fixed prices. One-time. No retainer required to get started.
Three on-brand emails that convert first-time visitors into buyers — written in your voice, Klaviyo-ready in 5 days.
Three cart recovery emails — 1h, 24h, and 72h post-abandonment — written in your brand voice.
Four emails that turn one-time buyers into repeat customers — from thank you to cross-sell.
All three retention flows — Welcome Series, Abandoned Cart, and Post-Purchase — built custom for your brand.
Pick your monthly store revenue. We'll show you how many days until the build pays for itself — based on conservative email benchmarks for Shopify stores.
Estimated at 3% of monthly revenue from a properly configured Welcome Series — conservative relative to industry benchmarks (2–8%). Your actual results depend on list size, open rate, and offer strength.
We had Klaviyo running for 8 months with zero flows live. $299 and 5 days later our Welcome Series was done. Converted at 6.8% in the first week.
The audit showed us exactly what was bleeding revenue. Core Three Bundle fixed it. We recovered $12K in the first 90 days just from the abandoned cart flow alone.
Hired an agency at $4,500/mo. Got generic copy and missed two deadlines. RetentionLab delivered the same three flows in 4 days for $799. Not a close call.
