What Our Clients Say

★★★★★

“Saqib is genuinely the best guy we have worked with. Their email campaigns have grown our website sales 138% YTD compared to last year. All of their emails are beautifully designed and the content is brilliant. I couldn't recommend them enough.”

“Saqib is our email marketing partner since the last 3 years. He's extremely professional. Always on time and helped us elevate our brand. He know cheat code of creating banger imagery so that we don't always ask to invest in high cost photoshoots. Over all great experience.”

ML
Marcus Lee GLP-1
★★★★★

“Have worked with Saqib for about a year, and it has been a very pleasant experience. He always delivers on time and replies immediately. I have worked with different larger teams before, where I got a new account manager constantly, and with that, had to spend a lot of time troubleshooting. With Saqib it's nice to know that won't happen, and it saves me a lot of time.
My best recommendations”

  • ABOUT FOUNDER

Your Retention Partner

ROI Booster is led by Saqib Rehman, an eCommerce retention specialist with 4+ years of hands-on experience working with and inside growing online brands, including operating a 7-figure eCommerce business.

Today, I manage retention across multiple brands and have helped generate $3M+ in email-attributed revenue through strategy, campaigns, flows, segmentation, creative, and optimization.

I don’t look at email in isolation. I look at the entire customer journey and focus on one thing: turning more of the customers you already paid to acquire into repeat revenue.

Frequently Asked Questions

01 What does ROI Booster do?

We manage the full retention channel - email, SMS, flows, campaigns, segmentation, deliverability, creative, and ongoing optimization.

02 Can you work with our existing Klaviyo account?

Yes. Most clients already have Klaviyo running. We identify what's working, fix what's leaking revenue, and build what's missing.

03 How do you measure performance?

Revenue per recipient, flow revenue, conversion rate, repeat purchase rate, LTV, engagement, and overall email/SMS contribution.

04 How long does it take to see results?

It depends on the starting point. Some improvements - like fixing broken flows, optimizing popups, or improving campaigns - can show results within the first few weeks. More meaningful improvements in retention, repeat purchases, and LTV usually build over 30–90 days as we test, learn, and optimize.

05 How much does it cost?

There’s no one-size-fits-all package. Pricing depends on your current setup, email/SMS volume, number of brands or markets, and how much you want us to manage. We’ll first understand where you are, what needs fixing, and what the biggest opportunities are - then recommend a scope and price that actually makes sense for your business.

06 How do we get started with ROI Booster?

Start by booking a free retention growth audit. We will review your current setup, discuss your goals, identify opportunities, and recommend the next steps for improving your retention performance.
