Frequently Asked Questions
What is included in the CTO Email List?
The CTO Email List contains 980K+ verified technology-leadership contacts — CTOs, VPs of Engineering, heads of technology, and technical founders — segmented by company size, funding stage, and industry.
Can I target startup CTOs at specific funding stages?
Yes — filter by seed through late-stage venture-backed companies, or exclude startups entirely and focus on enterprises.
Do records include engineering leaders below CTO?
VPs of Engineering, directors, and architects are included so you can run multi-threaded technical outreach.
How are the emails verified?
Each address passes four gates — domain check, inbox verification, a human researcher audit, and a privacy scrub — keeping bounces under 1.4%.
