The foundation of any customer marketing and advocacy program is your customer database. According to Marketing Sherpa, every month 2% of it decays. In the four customer marketing practices I initiated, a key early task was cleaning up the database and making it much more effective than it was.
Below is why customer contact database health has become a silent risk — and why unclear ownership keeps it that way.

Why Customer Database Health Is a Marketing Risk
Issues include outdated and inaccurate information, misspellings, duplicates, blank fields, poor geo location, and the wrong information type — such as the email address in the title field. This results in the inability to properly segment, decreased open rates, and increased opt-out rates.
To better understand how widespread this issue is, we recently conducted a survey of customer marketing professionals. The results were not good. We asked: “How would you describe the health of your customer contact database?”
| 0% | Excellent |
| 20% | Very good |
| 48% | Good |
| 24% | Not so good |
| 8% | Poor |
Respondents wrote: “Keeps me awake at night and the mistakes are embarrassing” and “Customer data hygiene (or lack thereof, actually) has been a consistent theme across all of the positions I’ve held in the last 8 years.”
This isn’t an abstract data problem — it shows up in real customer interactions every day.
These are your customers, and this can’t be acceptable.
If your database was in better shape, would you be able to:
➤ Identify former customer contacts and convert them to warm leads?
➤ Upsell more effectively?
➤ Decrease your GDPR and state email privacy compliance risk?
➤ Increase attendance at your in-person events?
The Ownership Gap That Keeps Data Decaying
The survey also asked: “Whose responsibility is it to keep the database as accurate as possible?”
| 40% | Marketing Ops |
| 20% | Customer Success |
| 20% | Multiple groups |
| 9% | Don’t know or nobody |
| 8% | Sales Ops |
| 0% | Customer Marketing |
Marketing Ops, Customer Success, Sales, or Customer Marketing?
At most companies, various silos have a piece of the puzzle. Nobody is looking at the big picture and the customer data continues to decay.
Generally:
➤ Marketing Ops is focused on the prospect database. They maintain the structure of the customer database, but not the actual data.
➤ Customer Success manually updates information for their VIP contacts, but data hygiene is not a KPI.
➤ Sales adds contacts during pre-sales, and this is usually the messiest.
➤ Customer Marketing is focused on acts of advocacy and defers to others.
That diffusion of responsibility is why the database keeps decaying — even when everyone has good intentions.
Customer Marketing is in the unique position to lean into updating contact data, which can move the health of your database up a notch. Working with Customer Success and Marketing Ops, determine which data points are important and manageable. Then, monthly for some data and quarterly for others, run a report in Excel. Either manually make a few changes in your CRM or make the updates in the spreadsheet for Marketing Ops to bulk upload.
Customer Marketing sometimes struggles to show value. By doing this, you will gain credibility and may build up the capital to suggest some of the more structural changes needed to communicate more effectively with customers. By spending time with the database, you will become better and better at understanding the subtleties of your accounts and segmenting the list so that the right customer receives the right message at the right time.
A Practical Way to Benchmark and Fix Database Health
If you want a clear baseline and a prioritized path forward, a structured assessment helps.
Want to go deeper? I have developed a Customer Contact Database Health Assessment. It is an analysis with a benchmark score that includes short and long-term recommendations to improve the management and effectiveness of your database.

Summary: Customer Contact Database Health: Who Owns the Risk?
Customer contact database health is not a technical detail — it’s a growth lever. When ownership is unclear, data decays quietly, undermining segmentation, advocacy, compliance, and trust. Customer Marketing is uniquely positioned to restore order by coordinating across teams, improving data hygiene, and turning customer insight into measurable business value.
FAQ 1: What is customer contact database health?
Customer contact database health refers to the accuracy, completeness, and usability of customer data across systems like CRM and marketing platforms. Healthy databases enable better segmentation, engagement, and compliance.
FAQ 2: Who should own customer contact database health?
No single team can own it alone, but Customer Marketing is well positioned to coordinate efforts across Marketing Ops, Customer Success, and Sales to maintain data accuracy and relevance.
FAQ 3: Why does poor database health hurt customer marketing?
Poor data leads to mis-segmentation, lower engagement, higher opt-outs, and compliance risk — all of which reduce the effectiveness of advocacy, events, and customer communications.
