What is B2B data cleansing?

B2B data cleansing means cleaning up the mess in your database by fixing typos, removing outdated entries, and ensuring your data is useful for your sales pipeline.

It’s not about adding new information, as lead enrichment tools do, but about making what you’ve already got accurate and ready to work with.

When your CRM hygiene is poor, with broken email addresses, duplicate entries, and incorrect job titles, it's no wonder your outreach fails. Regularly cleaning your data means you’re not wasting time chasing dead leads or sending emails to the wrong people.

Why is data cleansing important for B2B companies?

Poor data quality costs businesses a lot of money annually due to errors, inefficiencies, and lost sales opportunities.

Here's why investing in data cleansing pays off:

• Boost sales productivity: Reliable data means your sales prospecting automation is more effective, and your team spends less time chasing incorrect leads.

• Enhance targeting and outreach: Clean data enables precise targeting, improving outreach efforts for your B2B sales funnel.

• Improve decision-making: High-quality data supports better strategic decisions and sales pipeline analysis.

• Decrease missed sales opportunities: Accurate customer data helps you easily catch and convert hot leads.

• Contribute to data security and compliance: Keeping your data clean helps you avoid compliance issues and keeps your systems safe from outdated or inaccurate information.

How to keep your B2B data clean

Every time someone changes jobs, updates their title, or changes phone numbers, your carefully built database takes a hit. Before you know it, you're working with outdated information that is costing you deals.

Here's how to maintain data integrity.

Automate data enrichment

Manual data entry is time-consuming and error-prone. Automating data enrichment with B2B sales tools ensures your records stay complete and accurate without the tedious work.

We recommend using the AI LinkedIn Profile Enricher automation to skip the grunt work and keep your data clean and actionable. Instead of combing through profiles yourself, just feed your lead sourcing list to the tool and let AI do the heavy lifting.

It can:

• Standardize messy job titles (e.g., changing "Chief Marketing Officer / CMO" to a consistent "CMO" format).

• Strip out emojis and unnecessary characters from names and titles.

• Spot decision-makers based on their seniority levels.

For example, try this prompt:

Analyze the LinkedIn profile of the user. Identify and standardize their job title based on the following rules:

1. Standardization: Convert job titles to commonly recognized abbreviations where applicable.

- Examples: ‘Chief Marketing Officer’, ‘CMO’, ‘CMO & Head of Marketing’, or ‘Marketing Executive (CMO)’ → Convert to ‘CMO’.

- ‘Business Development Manager’ → Convert to ‘BDM’.

2. Formatting:

- Remove emojis, special characters, and unnecessary descriptors (e.g., ‘Interim’, ‘Consultant’ unless it’s critical to the role).

- Keep titles clean and straightforward (e.g., ‘Head of Marketing’ instead of ‘Head of Marketing & Growth 🚀’).

3. Output Format: Provide only the cleaned and standardized job title.

4. Validation: If the job title is ambiguous, output ‘Unclear - Review Needed’.

5. Example Input: ‘Chief Marketing Officer / CMO & Head of Marketing 🚀’

6. Example Output: ‘CMO’

💡 Tip: Be as specific as possible when setting up your prompts. The clearer your prompt, the better your results. Check our prompt guide to better write AI prompts for lead generation.

Remove duplicate entries

Nothing screams "we don't have our act together," like two team members reaching out to the same prospect with different messages. Duplicates waste everyone's time and reduce your pipeline velocity.

Start with a monthly cleanup ritual using your CRM's built-in tools. HubSpot, for example, offers data cleansing services with a duplicate management feature that catches records with matching emails or phone numbers.

Or take it a step further with Dedupely. It’s built for CRMs like HubSpot, Salesforce, and Pipedrive and automatically detects and merges duplicates without losing key details.

💡 Tip: Set a 15-minute calendar reminder once a month to get it done. You'll thank yourself later.

Track your contacts' activity and intent signals

Want to know which prospects are ready to buy? Intent signals are your answer.

These buying signals go way beyond job changes. They include website visits, content downloads, event attendance, and social media engagement. Each action tells you something about a prospect's current interests and buying readiness.

Try using PhantomBuster's HubSpot Contact Career Tracker to help you stay on top of job changes. This automation scans your HubSpot contacts’ LinkedIn profiles and alerts you whenever someone moves to a new company.

It also enriches your CRM by updating prospects' job title, company, professional email, and start date.

This is gold to help you maintain relationships when customers leave existing accounts, open doors at new companies where your customers have just arrived, and keep your CRM fresh.

💡 Pro tip: Set the automation to run 4-8 times daily, depending on your plan, to stay ahead of changes without missing a beat. This is perfect for keeping your CRM clean and ready for outreach.

Keep your CRM updated with real-time syncing

Have you ever had a perfect email bounce because the contact information was outdated? This can happen quite often, sometimes wasting gold sales opportunities.

We recommend scheduling PhantomBuster's HubSpot Contact Data Refresher to run weekly. This tool automatically checks your LinkedIn-connected contacts and updates your HubSpot records with fresh information.

Set it up once, then forget about it. Your data stays fresh without you lifting a finger, making your automated sales prospecting much more effective.

💡 Pro tip: Ensure your HubSpot contacts are enriched with their LinkedIn Profile URLs before launching this automation. Without this, the HubSpot Contact Data Refresher can’t do its job properly. You can use the HubSpot Contact LinkedIn URL Finder to get this data ready.

What are the differences between data cleaning and data scrubbing?

Data cleaning is the full maintenance check for your database, tackling all data quality issues, while data scrubbing involves correcting or removing incorrect values.

The main challenges of B2B data cleansing include:

• Data decay: B2B contact info goes stale fast as people change jobs and companies evolve.
