You Paid to Acquire Your Customers.
Now Make Them Worth It

Where Retention Marketing Creates Profit:

Higher repeat purchase rate

The average DTC brand's repeat purchase rate is under 28%. The best brands hit 40%+.

Revenue that compounds

A 5% improvement in retention can increase profits by 25–95%. Not because you spent more, because the customers you already have became worth more.

Off the acquisition treadmill

Every customer who doesn't come back needs to be replaced with a new one. Retention fixes the leak, so your acquisition spend builds on itself instead of just keeping up.
