About Retention Studios
Retention Studios is an email and SMS retention agency for health and wellness CPG brands. They build and scale lifecycle systems that turn first-time buyers into long-term customers, driving predictable revenue and higher lifetime value.
The Challenge
Retention Studios faced a high risk deliverability situation when a client underwent a full domain change. Years of established sender reputation were effectively reset overnight. With a brand new sending domain, engagement was low and inbox placement was uncertain. During the required warm up period, the client experienced an estimated $60,000 dip in email driven revenue.
The priority was clear. Rebuild trust quickly without triggering spam filters, restore engagement, and scale sending volume safely.
The Approach
Retention Studios partnered with Email Industries to design and execute a structured domain warm up plan that balanced speed with deliverability safety.
Email Industries supported the program with:
- A daily sending volume plan that increased gradually and predictably
- Segmentation guidance to prioritize engaged recipients early
- Ongoing inbox placement testing to validate performance at each stage
- Hands on advisory support to adjust tactics in real time
This approach ensured that every increase in volume was backed by positive engagement signals and healthy mailbox provider feedback.
The Results
The domain warm up progressed smoothly with no inboxing issues as volume scaled.
Key outcomes included:
- Recovery of roughly $60k of email driven revenue as sending volume returned to normal levels
- Successful ramp from roughly 200 recipients per campaign to 30,000 recipients per campaign
- Higher inbox placement rates and improved sender reputation
- Increases in open rates and click through rates
The warm up was completed without deliverability setbacks, allowing the brand to resume growth faster than expected.
Why It Worked
Email Industries acted as an extension of the Retention Studios team. The combination of daily volume management, segmentation strategy, and continuous testing removed guesswork from the warm up process and reduced risk at every stage.
Instead of reacting to problems after they appeared, the program focused on prevention and validation as sending scaled.
Looking Ahead
With a fully warmed domain and restored performance, Retention Studios is positioned to continue scaling email revenue with confidence. The foundation built during the warm up ensures stronger long term deliverability and resilience for future growth.
