Why data cleansing isn’t a technical job for later – it’s a commercial decision you need to make now.
Marcel Stirling runs Phoenix Insolvency. Like most small business owners, he had more important things to think about than the health of his contact database. His leads were in the system. The email sequences were set up. The team knew the process.
Then he ran a bulk email campaign, and his domain was blocked almost overnight.
Not because the emails were spammy. Not because anything had gone wrong with the content. Because too many of those 102,195 records in his database had quietly become undeliverable – wrong addresses, defunct inboxes, numbers that no longer existed. The bounce rate was so high that his email provider shut down his ability to send to anyone. Overnight, Phoenix Insolvency couldn’t contact a single client or prospect.
It’s a situation that can happen to any SME that hasn’t kept on top of its data. And the uncomfortable truth is that most haven’t.
The Problem Nobody Talks About
Data decay is one of those problems that feels abstract until it isn’t. According to Experian’s global research, around 30% of customer data becomes inaccurate every year. Not because of anything you did wrong – simply because people move house, change jobs, switch email providers, get married, or close old accounts.
For a database of 10,000 records, that’s 3,000 contacts drifting out of reach every twelve months. For a database of 100,000, it’s 30,000. And because the decay happens gradually, invisibly, there’s no alarm. No report flags it. Your database still shows the same number of records. It just stops working as well as it should – and you start blaming your subject lines.
Most SMEs only discover the scale of the problem when something forces the issue. A bounce rate that spikes. A campaign that dramatically underperforms. Or, in Phoenix’s case, a domain block that stops communications dead.
By that point, the damage is already done. The question is how quickly you can fix it.
What it Actually Costs You
The most obvious cost is the one Phoenix experienced – losing the ability to send emails at all. But for most SMEs, the cost is quieter and more insidious than that.
Think about your last reactivation campaign. The one that underperformed. The instinct is to look at the creative, the offer, the timing. Rarely does anyone ask: what percentage of that list was actually reachable? Because if 20% of the records had bad email addresses, the campaign was never going to hit its numbers – regardless of how good the copy was.
Or think about the renewal reminder that never arrived. The customer who didn’t get it didn’t call to say it hadn’t arrived. They just didn’t renew. And somewhere in your CRM, they’re recorded as lapsed – when actually, they were unreachable.
These customers didn’t leave. They just stopped receiving your communications. That’s a very different problem, with a very different solution.
Think about what you spend on email marketing, outreach campaigns, or lead nurture sequences in a year. Every pound of that budget that lands on an undeliverable record is money spent on silence. It doesn’t bounce back to you. It just disappears.
The Fix is Simpler Than You Think
Here’s what happened when Phoenix Insolvency worked with FLG’s data cleansing division to sort it out.
The full database – all 102,195 records – was exported as a CSV file and passed to FLG’s data cleansing team. Each email address was assessed against three criteria: deliverable, undeliverable, or risky. Phone records were validated in parallel. The cleansed file was returned, uploaded back into FLG, and Phoenix was back up and running.
There was no lengthy IT project, no technical integration, and no disruption to existing systems. Just a file export, a cleanse, and a file back.
“I expected it to be a much bigger undertaking than it was, given we had over 100,000 records, but it’s as simple as saying yes and exporting a file. Don’t wait until you have a problem to deal with it. We learned that lesson the hard way.”

And critically, rather than simply deleting the problem records, the team rated each one. Undeliverable addresses were suppressed. Risky ones were flagged for review. Data that still had value was preserved. Phoenix came out of it not just with a working database, but with a clear picture of what was actually in it.
The results were immediate. Within a short time of the first send after the cleanse, Phoenix Insolvency had received four new client applications. From a database that had been completely silent. Marcel said:
“The data cleansing team turned what felt like a crisis into a straightforward fix – and in just a couple of days. We went from not being able to contact anyone to generating four new client applications from a single send. The data cleanse didn’t just fix a problem – it opened the door again.”
The Cost vs Return Argument
This is the part that matters most for any SME weighing up whether to do something about their data.
A data cleanse is not expensive. Relative to the cost of a wasted email campaign, a lost renewal, a failed reactivation sequence, or – worst case – a domain block that stops your business communicating entirely, it pays for itself many times over.
Phoenix Insolvency got four new client applications from a single send. The question isn’t whether you can afford to do it. It’s whether you can afford not to.
And the good news, as Marcel discovered, is that it’s far less daunting than it sounds. No data team required. No technical project to manage. Just say yes and export a file.
Don’t Wait for the Crisis
Most businesses that end up in Phoenix’s situation didn’t ignore their data out of negligence. They just had other priorities. The database was working well enough. There were campaigns to run, clients to serve, and a hundred other things that felt more urgent.
Data decay doesn’t send a warning. It just quietly accumulates until the day something forces the issue – and by then, the fix takes longer and costs more than it would have done six months earlier.
The businesses that stay ahead of it treat data cleansing the same way they treat any other operational maintenance. Not as a crisis response. As a regular, straightforward part of keeping the business running properly.
“We see this more often than people realise – a database that looks fine on the surface, quietly decaying. Data doesn’t maintain itself, but the good news is it’s always fixable, and quickly.”
– Tracey Moir, FLG Data Cleansing
If you’re not sure how healthy your database is right now, that’s probably the answer. The longer it’s been since you last cleansed it, the more of your contact base is silently unreachable – and the more revenue you’re leaving on the table as a result.
