Emailium

Emailium is a retention marketing agency helping DTC brands turn email into their most profitable revenue channels.

We build and scale lifecycle marketing systems that increase customer lifetime value, drive repeat purchases, and unlock revenue that most brands leave on the table.

Having worked with 100+ eCommerce brands, our strategies have generated $500M+ in Klaviyo-attributed revenue through data-driven segmentation, automation, and a full-funnel retention strategy.

We don’t believe in isolated campaigns or guesswork.

We build structured retention systems that align with your customer journey from first purchase to long-term loyalty.

We partner with brands that:

• Rely heavily on paid ads but underutilize email & SMS

• Have email flows but lack a clear retention strategy

• Want to increase repeat purchases and customer lifetime value

• Need a scalable system, not just campaigns

If your email isn’t driving a meaningful share of your revenue, there’s a gap.

Emailium helps you fix it.
