Should I use the CTO's personal or work email?

Work email. Personal email outreach reads as invasive and can damage your sender reputation. Use LinkedIn DM as the secondary channel if work email does not respond.

Can I send a CTO a code sample in cold outreach?

Yes, as a link to a GitHub gist or repo. CTOs evaluate by trying. A working example link is worth more than a 5-paragraph product description.

How important is the rep's technical background?

Helpful but not required. The artifact carries credibility. A non-technical rep paired with developer-authored content can run effective CTO cadences.

Should I follow CTOs on X before reaching out?

Yes, and engage substantively on their posts. A thoughtful X reply 1 to 2 weeks before the cold message warms the relationship in a way no email-only cadence can.
