How to find emails of C-level executives in “buying mode” with ListKit (in three simple steps)

Intent data reveals when decision-makers are actively researching products or services like yours. For C-level outreach, this is a game-changer—it lets you target executives already in the market, increasing your chances of getting a reply.

1. In ListKit’s Intent Data tab, choose topics relevant to your target executive—e.g., ERP systems for CFOs, CRM software for CMOs, or cloud infrastructure for CTOs. (Pro tip: Use ChatGPT to brainstorm topic ideas specific to each C-level role.)

2. Filter by job titles like CEO, CFO, COO, CMO, CTO (plus industry and company size if needed). For this example, we’ve selected topics related to CTOs, so we’re going to select “Chief Technology Officer”.

3. Export Triple-Verified emails & phone numbers (95%+ accuracy) for immediate outreach, and refresh daily to keep a steady pipeline of in-market executives.

Key Factors for Choosing a C-Level Email List Provider

Before diving into individual providers, let's establish what actually matters when you're targeting the C-suite.

1. Data Accuracy & Verification

If you're serious about C-suite outreach, accuracy isn't negotiable.

Providers that use ListKit’s Triple-Verification dramatically reduce wasted effort by delivering only contacts that have been checked at multiple points. This means you're not chasing dead ends or cleaning up messy data.

Rik, an Account Director, shared in his G2 review:

“Easy to use, fast searching to build verified emails (x3 verified) means I can streamline my workflows. I don’t need to export from Apollo, go into three other verifier software, run, upload, etc. This is a one-stop search and export.”

Here's what verification levels actually mean:

BTW, downloading leads is the easy part. The real challenge? Finding contacts who actually reply.

Mini Case Study: When Luis switched to ListKit, he booked 15 calls and signed $5K MRR in just six weeks—proof that ListKit’s Triple-Verified data and hands-on support drive real results.

2. Compliance & Deliverability

With privacy laws getting stricter, you want a provider that's upfront about GDPR, CCPA, and CAN-SPAM compliance.

Furthermore, it should ideally support strong deliverability by offering features like private SMTP or pre-warmed domains.

If you're new to outbound or just want a refresher on compliance basics, this overview of outbound B2B lead generation breaks down the essentials.

3. Workflow Integration & Support

Getting your list is just step one. The best providers make it easy to push contacts straight into your CRM or sending platform, and offer responsive support if you hit a snag.

Must-have integrations:

• Native CRM connections (HubSpot, Salesforce, Pipedrive)
• Email automation tools (Outreach, Mailchimp, Smartlead)
• Workflow platforms (Zapier, Google Sheets)

4. Segmentation & Targeting

Precision targeting is what separates a 'meh' list from a high-performing one. You want filters for role, industry, geography, company size, and—if possible—buying intent.

BTW, ListKit stands out here: you can slice your audience by intent signals, so you're not just reaching any exec, but the ones actually searching for your offer.

The best email verification tools help keep your lists clean and focused. That means fewer bounces, more replies, and more booked meetings—without spending hours cleaning spreadsheets.

The "C-Suite Data Fit" Framework

Red flags to avoid:

• Outdated lists with no refresh schedule
• Vague verification claims ("verified data")
• Missing compliance documentation
• Clunky or limited integrations

Quick Tip: Executing C-Level Outreach

Once you've got your list, personalize your messaging and use a multi-step approach.

Here's the framework that works:

1. Research the executive's recent company news or initiatives
2. Lead with a relevant insight or industry trend
3. Keep your ask specific and time-bound
4. Follow up 3-5 times over 2 weeks

If you're unsure how to structure your follow-ups, these cold email follow-up templates work especially well for C-suite outreach—definitely worth a look early in your planning.
