Update addresses by matching with:
- Change-of-address data (relocation matching)
- Deceased persons (data cleansing)
- Undeliverable addresses (deliverability check)
- Negative and blocking lists
Duplicate Cleansing
Good target-group selection often results in duplicates between rented data and your own addresses. Duplicates within a single list are also not uncommon. Matching identifies and documents these. This saves costs for addresses, letters, and postage.
The greatest benefit is for your customers, who expect to be contacted only once!
In addition to removing duplicates, we can also match your lists against all types of blocking lists, such as the Robinson list, and produce a fully cleansed, unique address file.
Your Benefits from Duplicate Checks:
- Cost savings
- Higher customer satisfaction
- Improved company image
- Higher response rates for marketing activities
By Performing a Move Update, You Avoid:
- High return rates
- Multiple mailings (to the old and new address)
- Unnecessary expenses for production, shipping, and postage
- Inefficient marketing activities
Address Updates Through Relocation Matching
Approximately 22,000 people in Germany move every day. Over one year, around 12% of your customers will be among them. Only very few report their new address to service providers or contractual partners. As a result, many of your customer and prospect addresses become outdated.
With relocation updates, you can maintain contact. Don’t lose customers who have moved or who are now active under a new name (e.g., due to marriage).
Using our relocation update, which draws on all available reference data, we bring your data up to date and return moved customers to your database.
Deliverability Check
Even in well-maintained databases, addresses may become undeliverable when people move and leave no trace.
Since undeliverable mail is not returned to you, you can only detect this by using Premiumadress during shipping or through relocation matching.
If you want to be informed before mailing, we recommend performing a deliverability check as part of your data processing. This saves you production and postage costs for your mailing or catalog.
Our Deliverability Check Includes Verification of:
- Names and first names of individuals or company names
- Streets and house numbers or PO boxes
- Postal codes and cities
Your Benefits:
- You reduce the undeliverable rate
- You save significant costs for production and mailing
- You protect your reputation and avoid complaints from bereaved families
Deceased Person Matching and Data Cleansing
Unfortunately, customers from your database may also pass away. Family members living at the same address may still receive your mailings but are often deeply affected. If the customer lived alone, your marketing mail cannot be delivered. Professional data cleansing helps you avoid such situations.
As with relocation updates, we can match your data against reference lists to flag deceased individuals or remove them when using external address lists.
Clean your data and remove addresses of deceased persons from your database!
