Building your own CTO list costs 2.3 to 3.6 cents a contact, and the same plan sends the emails.

A prebuilt file is a one-time download that starts going stale the day you buy it. In Lead Finder you choose exactly which CTOs go in, add more whenever you need them, and the plan that pays for the credits also sends the emails.

Way to get the listWhat you payCost per contact
Emailchaser Pro$97 a month with 5,000 lead credits and 125,000 emails a month included2.3 cents
Emailchaser Starter$47 a month with 1,500 lead credits and 5,000 emails a month included3.5 cents
Emailchaser extra credits$33 per 1,000 credits, or $20 per 1,000 when you buy 5,000 or more; bought credits never expire2.3 to 3.6 cents

Sources: Emailchaser plans and credit prices from emailchaser.com/pricing, read 17 October 2026 (1 lead credit adds 1 person; plan credits refresh monthly). Each Emailchaser cost includes checking the address at most twice, $0.0034, which is on by default. Cost per contact is the price divided by the contacts it buys.

Three steps take you from a CTO search to a sent campaign.

Everything happens in one account, so there is no file to download, clean and upload somewhere else.

Example campaign and email, invented for this page. The count is real.

Developer tool makers, cloud providers and engineering agencies use CTO lists to reach the person who picks what a team builds with.

At a startup the CTO is often a co-founder who chooses the cloud, the tools and the contractors personally, and answers email quickly. At a larger company the CTO sets direction while engineering directors run the purchase, so a message about architecture or security gets further than a price list. Filter by company size to separate a founder from an executive, and add an industry to focus on one kind of product.

These are the questions people ask about CTO email lists.

How many CTOs can I reach with Emailchaser?

Lead Finder holds 44,688 US contacts with a CTO job title with a verified work email, from a live count on 3 November 2026. The count changes as people change jobs, so the number you see in Lead Finder on the day you search is the one that counts.

Can I filter CTOs by state, city or company size?

Yes. Lead Finder filters by country, state and city, by seniority (for example owner, partner or director), by company size from 1-10 employees up to 10,001+, and by job title, revenue and the technology a company uses. Combine them freely, and the count updates before you spend anything.

How much does a CTO email list cost on Emailchaser?

Searching and counting are free. Each person you add uses 1 lead credit. Plans include 1,500 credits a month on Starter ($47), 5,000 on Pro ($97) and 10,000 on Max ($358), and extra credits cost $33 per 1,000, or $20 per 1,000 when you buy 5,000 or more. Checking each address is billed apart from credits, at $0.0017 a check. The 7-day free trial includes 500 lead credits.

Do CTOs at small startups read cold email?

Often, yes, because the CTO of a company under 50 people is usually a founder who reads their own inbox and picks their own tools. A short message about a specific problem works better than a product overview. Filter by company size 1 to 50 in Lead Finder to focus on them.

Are the emails verified?

Lead Finder only returns people whose work email has a verified status. When you add them, Emailchaser checks each address again (on by default, $0.0017 a check, one or two checks an address), and an address that fails is dropped without using a credit.

Is it legal to send cold email to CTOs?

In the United States, the CAN-SPAM Act allows commercial email to business addresses when you identify yourself honestly, use an accurate subject line, include a postal address and honour every opt-out. Rules are stricter in some other countries, such as under GDPR in Europe.
