Trebbau markets customer and prospect address lists for businesses that want to generate additional revenue from their existing lists. We analyse your list, advise on positioning and rental pricing, approach suitable list renters and handle the agreed operational tasks through to invoicing.
You decide which businesses may use your address list.
What does renting out address lists mean?
Renting out address lists means making suitable customer or prospect lists available to other businesses for defined advertising activities.
Professional list management brings together businesses with marketable address lists and suitable advertisers. This gives list owners the opportunity to generate additional revenue from an existing customer list.
Trebbau handles professional list marketing and coordinates the use of your list with you.
Which address lists are suitable for marketing?
Well-maintained customer and prospect lists with clearly defined audiences and suitable selection criteria are particularly suitable for address list marketing.
The size of a list alone is not the deciding factor. It is equally important how precisely the audience can be described and selected for potential list renters.
Market B2C address lists
For B2C lists, information such as age, gender, purchasing power or buying behaviour can be relevant to audience definition and selection. Which characteristics are actually available and can be used for marketing depends on the individual list.
Market B2B address lists
For business addresses, information about relevant contacts and available selection criteria is particularly important, alongside details about the company itself.
The more precisely an audience can be described, the more selectively the list can be offered to suitable list renters.
How address list marketing works with Trebbau
Assess your address list
First, we gather the relevant information about your list. This includes its size, audience structure and available selection criteria.
This allows us to assess how the list can be positioned in the market and which advertisers might be interested in the audience.
Define positioning and commercial terms
Together, we define the rental price, commercial terms and other conditions. Trebbau then prepares the relevant information about the audience, list and selection options for marketing.
Actively market your address list
Trebbau approaches suitable prospects from its own network and the relevant market – in the B2B and B2C sectors, both nationally and internationally.
Approve and process enquiries
When a specific enquiry is received, you are given the relevant information about the planned use of your address list. You decide whether to approve its use and can exclude particular companies, competitors or industries, for example.
Following your approval, Trebbau handles the agreed operational tasks through to invoicing.
What you could earn

Data quality as the foundation of address list marketing
Up-to-date, well-maintained address lists are an important prerequisite for professional list management. Trebbau can therefore combine list marketing with data preparation and updating services where needed.
Depending on the initial situation, checks for duplicates, suppression lists, people who have moved, deceased individuals or undeliverable addresses, as well as other data updating measures, may be useful.
The measures relevant to your list depend on the existing data quality and intended use.

Frequently asked questions about renting out address lists
For an initial assessment, information about the size, audience and available selection criteria of your address list is particularly relevant. Depending on the list, further details may be required to assess its revenue potential.
The rental price is determined based on the specific address list and its marketing opportunities. Relevant factors include audience, list size, data quality, selection criteria and market demand. Trebbau supports the assessment and the setting of commercial terms.
Yes. As the list owner, you decide which businesses may use your list. Specific enquiries are discussed with you. This allows competitors or particular industries to be excluded from using the list, for example.
Potential revenue cannot be stated as a fixed amount. It depends on factors such as the audience, size, quality and selection criteria of the list, as well as market demand and agreed commercial terms. An individual assessment of the specific list is therefore more meaningful than a general revenue estimate.
When marketing customer and prospect data, the applicable data protection requirements must be taken into account. The requirements in a specific case depend on factors such as the dataset, the origin of the data and the intended use, and should be assessed for the respective marketing model.
