Trebbau markets customer address lists and available parcel insert spaces for businesses that want to generate revenue from their existing lists and shipping capacity. We advise on marketing opportunities and commercial terms, approach suitable advertising partners and handle the agreed operational tasks.
You retain control over who may use your address lists or insert spaces.
What is address list and insert marketing?
Businesses often have assets that can generate revenue beyond their own marketing activities: qualified customer lists or unused capacity in parcel shipping.
In address list marketing, suitable customer or prospect addresses are made available to other businesses for defined advertising activities.
In insert marketing, businesses make available space in outgoing parcels or shipments for other companies’ advertising inserts.
Trebbau brings providers and suitable advertising partners together and supports the process from assessment through to fulfilment.
Which assets can businesses market?
Market your customer address lists
Well-maintained customer and prospect lists can be of interest to other advertisers. The size of the list alone is not the deciding factor. Audience profile, data quality and available selection criteria are particularly important.
Trebbau assesses the revenue potential with you, advises on positioning and commercial terms, and approaches suitable businesses interested in renting your lists.

Market your parcel insert spaces
Businesses that regularly ship goods or parcels can offer available insert spaces for other companies’ advertising materials. Relevant factors include shipping volume, recipient structure, audience profile and the number of inserts that can be accommodated.
Trebbau prepares the necessary marketing information and approaches suitable advertising partners.
How Trebbau supports the marketing process
Potential and commercial terms
We begin by assessing your current situation. For address lists, we consider factors such as audience, list size, data quality and selection criteria. For parcel inserts, relevant factors include shipping volume, recipient structure and available capacity.
This forms the basis for defining positioning, commercial terms and other conditions.
Active marketing
Trebbau prepares the relevant information for the market and approaches suitable businesses, agencies and other market partners. We draw on our direct marketing experience, market knowledge and established contacts in the B2B and B2C sectors.
Handling and control
Specific enquiries are discussed with you. As the list owner, you decide which businesses may use your list. As the shipping company, you determine which advertising partners and materials may be included in your shipments.
Trebbau then handles the agreed operational tasks through to invoicing.

Frequently asked questions about address list and insert marketing
For address lists, audience profile, list size, data quality and selection criteria are particularly relevant. For parcel inserts, factors include shipping volume, recipient structure and available capacity. Whether marketing is worthwhile should be assessed based on the individual list or shipping model.
Trebbau considers the information relevant to the respective type of marketing and assesses how the offering can be positioned in the market. This helps identify suitable prospective partners, commercial terms and other conditions.
The specific arrangements depend on the marketing model and agreed scope of services. Commercial terms are therefore agreed based on your individual circumstances.
We begin with an initial review of your address list or available insert capacity. For this, we need some basic information about your list, audience or shipping structure. We can then assess which next steps would be appropriate.
