Every Bad Data You Can Find in Every B2B Telemarketing Campaign


Insufficient data in, incomplete data out. For B2B telemarketing campaigns, incomplete data means a lot of bad news for companies. Working on harmful and inaccurate data results in the following:


  • 27.3% or 546 hours/year wasted time of sales reps
  • 12% of company revenue loss
  • 21% of wasted marketing budgets
  • Smaller companies lose 6% of annual revenue
  • 21% of companies suffer from reputational damage
  • Insufficient data costs U.S. businesses more than $611 billion annually

It doesn’t matter if you get the best partner from telemarketing services companies if they work on your insufficient data. 

Insufficient data has been the culprit of wasted time, wasted marketing budgets, revenue loss, and reputational damage. 

After all, data is crucial in shaping your B2B telemarketing, whether you are a first-timer in this strategy or a business that has been using it. 

It is good to note that a 75% success rate of marketing strategy relies on accurate and updated data. 


Sources of Bad Data in B2B Telemarketing?


Two primary sources of evil can affect your B2B cold calling services, B2B telemarketing, and eventually your business profit and revenue. These are the following:


  1. Poor data from the start due to data entry errors or the purchase of unverified lists
  2. Deterioration of data quality over time due to natural data decay or poor CRM maintenance


Insufficient data means inaccurate sets of information. The following are insufficient data common in B2B telemarketing or B2B cold calling services


Poor Data (Pre-collection) Data Decay (Post-collection

No Data

Unfortunately, some businesses do not believe in the importance of good data or data in the initial stages of any B2B telemarketing campaigns. 

Business demographics that usually suffer from this misconception are small to midsize enterprises. 

Outdated Data

Data decay is inevitable and is the natural death of data sets. Changes in the following information drive this:

1. Email

2. Contact Number

3. Change in Positions

4. Change in Company Name 

5. Shutdown of Company

Missing Data

This is due to missing or incomplete data fields. To illustrate, you could have the name and position of your targeted vital decision maker but no contact number or email. 

This is still insufficient data and therefore needs verification to complete or eliminate. 

Duplicate Data

This happens for various reasons: migration, manual data entry, third-party connectors, data exchanges, and batch imports. 

Commonly duplicated data are Leads, Accounts, and Contacts.

Inaccurate Data

There are tons of reasons at play here. This could mean wrong input of information into the inaccurate data set or false information altogether. 

Discrepancies like misspellings, wrong attribution, or typos could lead to this insufficient data.


From the table above, misbehaving practices in data entry work result in insufficient data. However, data decay is also a factor you need to consider, as it affects your whole database. 


What Kind of Data Sets for B2B Cold Calling Services are Prone to Data Decay? 


Let’s say your database does not possess what we listed above as insufficient data. Yet you are still missing targets and suffer from the consequences of inadequate data. 

The culprit is data decay. Unlike fine wine, good data does not age well with time. Such is inevitable. 

Statistically, there are 25% data decays per year. What data suffers from data decay, and what is the percentage? Take a look at the following figures.

Data and Information Percentage of Data Decay
Lead Change Positions 65% of people change jobs or titles a year

21% of CEOs change per year

Contact Numbers 43% of people change phone numbers per year
Email Address 37% changes email per year
Shift or Changes Companies 76 people change jobs every minute
Name Change of Companies (acquisition or merger) 34% of companies change their name annually
Postal Address 20% changes annually

From the table above, we can conclude that the crucial information you need for successful outsourced telemarketing is prone to data decay. 


How Bad Data Affect Your B2B Telemarketing Efforts?


These are the effects of insufficient data on your call center telemarketing or B2B cold calling services

1. Kills your marketing campaigns

It doesn’t matter how brilliant your marketing is, whether email, social media, or telemarketing if you are working with insufficient data. 

Insufficient data gives the wrong information to your sales representatives and telemarketing agents. Your agents could be dialing the wrong numbers, thus wasting effort.  

42% of sales reps believe that working with patchy and inaccurate data sets hinders them from doing their job well, which may result in poor quality of leads generated or poor conversation. 

Also, insufficient data leads to mismatched marketing messaging and wastes budget allocation and time. Imagine sending hundreds of emails to non-existent recipients. 

2. Decreases Customer Satisfaction

Outsourced telemarketing works well because it provides genuine conversation between your business and customers. Nurturing existing clients while going after new ones makes telemarketing an effective tool to increase ROI.

Bad data can ruin this effort for your business. To illustrate, email personalization is a strategy in your B2B telemarketing campaign. Imagine addressing the person with the wrong spelling of their name, company name, and current position. 

This gives the impression that you do not know your loyal customers. Worst of all, you did not even take the time to get to know them. 

The same is also applicable to B2B cold calling services. Your agents referencing insufficient data may not address the critical decision-maker adequately, which could turn them off. 

3. Wasted Budget Allocations

Insufficient data also affects business projection and strategy. When you base your judgments on dirty data, you may allocate budget and efforts to unproductive business strategies. 

Tainted data also hinder you from getting to know your core business persona, which leads to failure in creating marketing messaging that will resonate with them. As well as delivery at the opportune time to maximize its potential. 

How to Measure Data Quality?


You can take various steps to ensure your database is pristine as it should be. It would be best if you asked the following questions:


Pre-collection Post-collection
Data Availability 

Does your business have a database?


Do you have the latest and current information on your leads?


Are these data values acceptable and valid?


Does your database correct and represent timely and accurate information?


Is the data based on universal truth?

Are there variants available in different locations?


Is your database consistent and relevant?


Is the relationship between the data set and corresponding data entry accurate?


Does it cover all the basics to carry out granular segmentation?


Does the data value portray accurate and defined data properties for the object model?


Is the data appropriate or relevant for the data objective?


Periodic review and update of your database will help your outsourced telemarketing and B2B cold calling services be a success. 

Remember the 1-10-100 rule when dealing with insufficient data. It costs $1 to verify data in the pre-collection stage, $10 to fix erroneous data, and $100 when you do nothing about it. 


Benefits of Good Data for Your Outsourced Telemarketing


You reap the following benefits when you let your call center telemarketing services work on good data.

1. Good Data Helps You Identify Your Target Audience

B2B telemarketing success happens when you deal with a specific target audience as possible. Your good database lets you identify your ideal customer profile or target business persona. 

This sets the tone for your whole marketing campaign. As well as your B2B telemarketing efforts and B2B cold calling services

2. Better Marketing Strategy

With a clear picture of your targets, you can create a marketing message they can relate to. Also, you can identify which channels (social media, website leads, cold calling, inbound telemarketing) provide you with the most deals. This way, you can focus on these or improve or eliminate your weakest marketing link.

3. Reduce Duplication and Marketing Redundancies

No one likes spamming with marketing content through email or calling them twice. With good data, you can avoid these redundancies that cost money, time, and reputation.
