Thirdly, Cognism’s Intent Data partnership with Bombora was the final piece of the jigsaw. All of these collective features ultimately led to our decision to have Cognism as our B2B data vendor of

What’s the best way to get CIOs’ email list?

The best way to get a tailored CIO email list with additional B2B data points to personalise your emails is to use a sales intelligence provider like Cognism.

Create CIO email lists right in Cognism’s database.

You can gather all these data points using Cognism Prospector

  1. First, create a lead list based on your ICP.
  2. Next, narrow your search to specific criteria using Cognism’s advanced filtering options, like job title, seniority, sales event triggers (e.g. job change), etc.
  3. You can filter your search down depending on firmographics, such as industry, company name, number of employees, and revenue size, or further explore their specific SIC, ISIC, or NAICS codes.

If you want to create an ABM campaign tailored to a series of concrete events, go the extra mile by leveraging Bombora’s intent data fully blended into the Cognism platform.

Once you generate CIO lead lists, export them to Salesforce, Outreach, or another tool you use. 


For example, Kelly Services, an enterprise company in the recruitment industry, uses the Cognism platform to target four levels of seniority in CxOs, Talent Acquisition, HR and individual departments depending on the company size to get their valid contact details.

Intent data plays a crucial role in finding customers before they make purchasing decisions. The ability to generate lead lists in Cognism Prospector, using intent topics, helps BDMs refine the list according to surge number. After syncing the list into their CRM, BDMs contact the prospects within the surging accounts with a personalised message.

What to do when CIOs ignore your emails?

Just about every IT company across the world are trying to sell to CIOs. To ensure your message gets across, you can call them directly using Cognism’s phone-verified mobile numbers (aka. Diamond Data®). Unlike direct dials, Diamond Data® lets you avoid gatekeepers and answering machines.

Cognism’s data team manually checks each mobile number in the premium data asset to ensure you connect with the right prospect. 

With Diamond Data®, you can:

  • Connect with 87% of your list.

  • Increase connect rate by 3x.
  • Stay CCPA and GDPR-compliant.

Is buying a CIOs email list online a good idea?

Buying pre-made email lists of CIOs online isn’t the best option.

First off, these lists tend to be filled with outdated, inaccurate data that drives down your deliverability rates. You’ll likely send many well-crafted emails to people who aren’t in charge of information technology strategy and implementation.

Another common issue with buying a generic C-level executives’ email database is that you may run into compliance issues. 

Unlike Cognism, some email list-makers don’t abide by GDPR and other regulations when collecting their email data. This puts your business at risk.

How to prospect to Chief Information Officers? 

Prospecting to Chief Information Officers requires a strategic multi-channel approach with a lot of preparation. Use the tips below for maximum efficiency. 

1. Build trust rather than sell

Collaborate with subject matter experts in technology and security to gain industry insights and deliver thought leadership content to showcase your expertise. It will boost your credibility, and technology leaders will take your advice/offers more seriously.

2. Segment your prospect list

Only some CIOs on your email list will need your service. Use Cognism’s intent data to identify accounts actively searching for your product or service and target key decision-makers when they’re ready to buy. 

3. Add meaningful value

Show immediate value by clearly explaining how your product or service can address the pain points and challenges the CIO and IT senior management face in their company. Focus on the long-term value rather than quick wins.

4. Act in a credible, trustworthy manner

If you have mutual connections, ask them for a warm introduction. You may also ask the CIO’s counterpart in your organisation to break the ice between the two of you. Or mention that person X recommended contacting them. 

Remember: use only a compliant CIO email list and phone numbers.

5. Demonstrate your offering’s ROI

Buying a new product or service is an investment. You must convince the CIO that your offer will likely translate into more money or other business goals.

Share success stories or case studies from clients who achieved measurable ROI with your solution. Quantify the benefits of your solution; provide numbers or percentages if possible.
