Trusted by brands like
Your email is leaving $90K+ on the table every quarter.
Generic batch-and-blast emails.
You're sending the same message to your whole list and hoping. It gets ignored, drags down your deliverability, and trains your best buyers to tune you out.
Basic template flows that don't convert.
Your welcome, abandoned-cart and post-purchase flows are default templates that leak revenue every single day they run unoptimized.
You treat your list like a megaphone.
A list is a relationship, not a broadcast channel. With no real segmentation or lifecycle timing, your VIPs get the same email as a cold lead.
Competitors are out-emailing you.
The brands taking your repeat customers aren't spending more on ads. Their email just converts better, and that gap compounds every quarter you wait.
That's revenue you've already paid to acquire, walking straight out the door.

Built by Ex-Klaviyo and an 8-figure DTC brand in-house email marketer.
Before founding Momentum, Charlie worked at Klaviyo, giving him an inside understanding of the platform. He then crossed the table to become an ecommerce operator, co-building an eight-figure DTC brand where retention became one of the company's largest revenue channels.
That experience shaped Momentum's philosophy: the best retention marketing doesn't come from theory. It comes from running a business where every email and SMS directly impacts profit.
Today, Momentum manages retention for 15+ brands, generating more than $6 million in email and SMS revenue in 2026 alone.

Questions, answered.
Simple: we'll add at least $90,000 in email & SMS revenue in your first 90 days, or you don't pay us. We can make that bet because our clients average 30-40% of their revenue from email. On the call we'll show you exactly how the $90K is measured, baselined against your current email revenue, and hit.
We offer both a performance based structure and a flat retainer. The full details are discussed on your initial call.
No lock-in contracts. We earn the relationship month to month. If we're not making you money, you shouldn't be paying us.
Most setups run email as an isolated channel. We run list growth, flows, and campaigns as one system with one number that matters: revenue per subscriber. The audit will show you the gap in your first week.
