How to handle bad contact info from a lead provider

When a lead provider sends bad contact info, your first step is to document the specific issues: wrong numbers, disconnected lines, or incorrect names. Your next move is to verify the data yourself and then communicate these findings back to the provider for correction or credit.

Verify the problem before you react

Before you assume the lead provider is at fault, double-check the contact information yourself. Redial the number, re-enter the address into your mapping tool, or look up the name in public records if you have additional data points. Sometimes, a simple typo on your end or a temporary network issue can mimic bad data.

It is also wise to cross-reference the provided information with any skip-tracing tools you use. If your own tools confirm the data is indeed incorrect or disconnected, then you have a solid basis for your claim.

Keep in mind that phone numbers can change hands, or a homeowner might have opted out from a previous campaign that is unrelated to your current outreach. Verify the specific reason why the contact information seems bad.

For example, if you call a number and it is a wrong number, make a note of it. If it is disconnected, note that too. These details matter when you talk to your lead provider.

Document everything for your records

Accurate documentation is crucial when dealing with bad contact information. Keep a detailed log of every instance: the lead ID, the contact information provided, the date and time of your attempt, and the specific issue you encountered.

If you made a call, note the outcome – 'disconnected', 'wrong number', 'not the homeowner', or 'opted out'. For addresses, take screenshots of mapping errors or public record discrepancies.

This detailed record serves as your evidence when you communicate with the lead provider. It helps him or her understand the scope of the problem and validate your claim for a credit or replacement lead.

A spreadsheet or your CRM can be a simple way to track these issues systematically. The more specific your notes, the easier it is to resolve the issue.

Communicate clearly and calmly with your provider

Once you have verified the problem and documented it, reach out to your lead provider. Present your findings in a clear, concise, and factual manner, avoiding emotional language. Refer to your detailed log.

Most reputable lead providers have a process for addressing bad data. He or she will likely ask for the specific lead IDs and the issues you found. Be prepared to provide all your documentation promptly.

Understand his or her policy on credits or replacements. Some providers offer a credit if the data is proven bad within a certain timeframe. Others might investigate and replace the lead.

Frame your communication around improving the quality of the leads you receive, rather than just complaining about a bad one. This approach is more productive for both sides.

Adjust your lead testing process

If you are consistently finding bad contact information, it might be time to adjust how you test new lead sources or batches. Instead of diving in with a large volume, start with smaller test batches.

Implement a quick verification step for a percentage of new leads before your team spends significant time on outreach. This could involve spot-checking numbers or addresses.

Use the feedback loop from your verification efforts to refine your criteria for future lead purchases. For instance, if certain property types or geographic areas yield more bad data, you might adjust your filters.

Testing is not a one-time event. It is an ongoing process that helps you maintain quality over time. You are trying to find where the actual problem lies, not just react to symptoms. You can learn more about how to evaluate lead quality beyond initial seller reply and maintain consistency when leads are slow.

You can also compare lead quality for different property types to see if the issue is isolated.

What if the problem persists?

If, despite your best efforts and clear communication, the lead provider consistently sends bad contact information, you face a tougher decision. A consistent pattern of bad data indicates a fundamental issue with his or her sourcing or vetting process.

At this point, you need to weigh the time and money you are spending on verifying and dealing with bad leads against the value of the good leads you are getting. It might be more efficient to seek out alternative lead sources.

Your time is valuable. Constantly fixing or disputing bad data detracts from your core business of talking to motivated sellers and closing deals. Consider exploring other options like comparing pay per lead vs paying a monthly subscription or buying a list vs buying a reply.

Sometimes, walking away from a consistently underperforming source is the most cost-effective decision for your business.

Questions people ask

How do I know the contact info is truly bad, not just a difficult lead?

Verify by calling the number multiple times or cross-referencing with public records. If it's disconnected, a wrong number, or definitively not the owner, it's bad data. A difficult lead is still the owner, just hard to reach or qualify.

Should I still try to reach out if some information, like the street number, is off?

No. Incorrect property addresses or major discrepancies in contact details mean you cannot accurately target the homeowner. It is a waste of your time and risks contacting the wrong person.

What if the lead provider doesn't credit me for bad data?

If you have clear documentation and the provider still refuses credit based on his or her stated policies, then you need to decide if that provider is worth your continued business. Consistency in his or her response is key.
