Building your own system administrator 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 system administrators go in, add more whenever you need them, and the plan that pays for the credits also sends the emails.

| Emailchaser Pro | $97 a month with 5,000 lead credits and 125,000 emails a month included | 2.3 cents |
| Emailchaser Starter | $47 a month with 1,500 lead credits and 5,000 emails a month included | 3.5 cents |
| Emailchaser extra credits | $33 per 1,000 credits, or $20 per 1,000 when you buy 5,000 or more; bought credits never expire | 2.3 to 3.6 cents |

Security, backup and monitoring vendors use system administrator lists to reach the people who keep a company's servers and accounts running.
A system administrator keeps servers, user accounts, backups and updates running, and is usually the first person called when something stops working. In a small or mid-size company the sysadmin often picks and installs security, backup, monitoring and remote support tools, and a manager only approves the spend. In a large company the sysadmin tests a tool and recommends it to the IT director. Sysadmins distrust marketing language, so short, technical messages with a free trial or a clear price get further. Filter by industry and company size to separate a school district from a bank.
These are the questions people ask about system administrator email lists.
How many system administrators can I reach with Emailchaser?
Lead Finder holds 61,361 US contacts with a system administrator or systems administrator job title with a verified work email, from a live count on 13 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 system administrators 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 system administrator 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.
Does the list include network and Linux administrators?
It includes job titles that contain system administrator or systems administrator, such as "Linux Systems Administrator" and "Network and Systems Administrator". A title that says only network administrator or IT administrator is not in it, so add those titles in Lead Finder.
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 system administrators?
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.
