Retention Marketing: quick answers

What is retention marketing?
Everything that turns first-time buyers into repeat customers: automated flows and planned campaigns through the channels you own, i.e. email, WhatsApp and SMS. It is the counterpart to performance marketing, which wins new customers through ads.
Do I have to start with every channel?
No. Most start with email. WhatsApp and SMS are added when they pay off, just like additional platforms in performance marketing.
What does it cost?
Working with us starts from €1,500 net per month. The exact price depends on channels and scope; we clarify this in the intro call. You pay tool and sending costs directly to the providers.
Which tools do you work with?
We prefer Klaviyo for email and SMS, and for WhatsApp we use providers of the official WhatsApp Business Platform. Everything runs in your own accounts.

How much revenue is hiding in your existing customers?

In 20 minutes you'll know which flows and channels you're missing and what they can deliver.
