They know the product, they’ve been through checkout, they trusted you. Yet most ad budgets go entirely to cold audiences. ## Split by purchase date When “all customers” is a single audience, the message stays generic. The meaningful split is purchase date: someone who bought last month shouldn’t hear the same thing as someone who bought a year ago. The first needs a complementary product, the second a reason to come back. ## Timing depends on how fast the product is consumed The repurchase window varies by product: 3-4 weeks for something consumed monthly, 10-11 months for a yearly purchase. Win-back campaigns built without knowing this interval arrive either too early or too late. ## How to use the list You can target by uploading your customer list to the ad platform; setup and match-rate issues are covered on the [customer match](https://oguzerol.com/en/customer-match-crm-lists/) page. The same list is also the best source for building a lookalike — because it’s made of people who actually bought. ## Exclude people who are still active Showing a “come back” ad to a regular customer is both wasted budget and an odd message. Active customers should be removed from the win-back audience. **How we start.** We first check how much of your customer data is actually usable. Reach out via the [contact page](https://oguzerol.com/en/contact/). ## Frequently Asked Questions ### How large does the list need to be? Match rates are never 100%, so part of the list won’t be found on the platform. Small lists may not reach the serving threshold; in that case a [lookalike audience](https://oguzerol.com/en/lookalike-audience-targeting/) is a better fit. ### Does email or phone match better? Uploading both raises the match rate. With only one field, a significant share of the list is lost. ### Any data protection concerns? Customer data is sent to the platform in hashed form, but before uploading you need to be sure your own privacy notice and consent setup permit it.

Work-hour packages Tell me about your business and what you need on WhatsApp or by phone; we agree on **a work block of somewhere between 5 and 40 hours** and I start doing what is needed. What you get is not a calendar window — it is net working hours spent directly on your business. I can use 40 hours working three days straight, or deliberately spread it out and finish it over a year — whatever the work calls for. I do not spend my time estimating how long something will take, I spend it doing the work; every hour I spend leaves a lasting result in your business. We keep going for as long as you find it useful. WORK BLOCKS ## Why not monthly? Is 40 hours a week? On a fixed monthly fee both sides are watching the wrong thing: you watch a fixed cost, the other side watches how many more contracts like this they can line up. Working by the hour puts us both in front of the same thing — the real value of the work that got done. I know not having an upfront answer to "how much will this cost in total?" is the natural cost of this model. But instead of paying a fixed fee for months to a setup that is not producing results, you only pay for the qualified time spent on your work — and you see exactly where that time went, start to finish. That is why my clients keep coming back. 5hours300€ + VAT60€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%205-hour%20work%20block.) 10hours500€ + VAT50€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2010-hour%20work%20block.) 20hours800€ + VAT40€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2020-hour%20work%20block.) 40hours1,400€ + VAT35€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2040-hour%20work%20block.)
