You worked hard to win their attention. Don't lose it after one sale.

Most brands spend heavily to win a first purchase, then barely stay in touch. Without the right emails at the right moments, customers drift away and that acquisition cost never pays off.

QCK builds email programs that keep customers coming back. We set up automated flows for every key moment, send campaigns your subscribers look forward to, and personalize messages based on what each customer actually wants.

  • Recover lost sales with abandoned cart and browse flows
  • Grow repeat purchases and customer lifetime value
  • Personalize every message with smart segmentation

FAQ

Questions & answers

Straight answers to what brands ask us before they sign.

Is email marketing still effective?
Very. Email reaches people who have already chosen to hear from you, and it's one of the most cost-effective channels for driving repeat purchases. Unlike social or ads, you own your list and aren't at the mercy of algorithm changes.
Which email platforms do you work with?
We work with leading platforms such as Klaviyo and Mailchimp, and we can help you choose or migrate to the right one for your business.
How often should I email my list?
It depends on your audience and offer, but consistency matters more than volume. We'll build a cadence that keeps you top of mind without driving unsubscribes, then adjust based on engagement.
Do you offer SMS marketing?
Yes. We can add SMS to your program for timely messages like launches, back-in-stock alerts, and abandoned cart reminders, coordinated with email so customers get the right message on the right channel.
