Cold email agency for cybersecurity companies
Sales.co runs done-for-you cold email for companies that sell security: product vendors, MSSPs, pentest shops and vCISO practices. Security buyers sit in IT and engineering, and those departments are a small part of this data: 6,332 contacts got a first cold email between March and August 2026 and 8 replied positively. That is 0.13%, under half the 0.29% across all contacts.
How IT and engineering contacts answer cold email
The unit is the contact: one person who got a first cold email from one of 20 B2B campaigns on the Sales.co platform between March 6 and August 31, 2026, with replies counted up to October 9, 2026. The campaigns sold different products and services, so the tables show how these people answer B2B cold email in general. A positive reply is one where the person shows interest, asks a question, asks to be contacted later or refers a colleague.
| Recipients | Contacts | Replied in person | Positive reply | Positive rate |
|---|---|---|---|---|
| All contacts in the 20 campaigns | 336,257 | 2,830 | 975 | 0.29% |
| IT and engineering departments | 6,332 | 38 | 8 | 0.13% |
With 8 positive replies this is a small sample, so the rate is a rough figure and the splits below show where the replies came from, not a ranking. One campaign supplied 1,627 of the 6,332 contacts (26%) and 5 of the 8 positive replies, a rate of 0.31%. The other 17 campaigns together got 3 from 4,705, or 0.06%.
By department
| Department | Contacts | Replied in person | Positive reply | Positive rate |
|---|---|---|---|---|
| IT | 2,597 | 17 | 5 | 0.19% |
| Engineering | 3,735 | 21 | 3 | 0.08% |
By company size
| Recipient's company | Contacts | Replied in person | Positive reply | Positive rate |
|---|---|---|---|---|
| Up to 500 employees | 4,242 | 24 | 6 | 0.14% |
| More than 500 employees | 1,902 | 12 | 1 | 0.05% |
| No size on file | 188 | 2 | 1 | 0.53% |
The security buyer is the most sequence-aware audience in B2B. The title list is short and every vendor in a category mails the same people, so Sales.co does not blast it: per-prospect copy and a real reason for contact, or nothing. At companies under 500 staff nobody has security in their title, and the CTO or head of IT is the real buyer for most MSSP and vCISO offers.

Who Sales.co emails for a security company
| Segment | Who gets the email |
|---|---|
| CISO | Worth contacting only with something specific about their environment |
| VP Security | Owns the budget line in larger organizations |
| Director of security engineering | Reads the technical claim and will check it |
| Head of GRC or compliance | The route in for audit, evidence collection and questionnaire work |
| CTO or head of IT, under 500 staff | Owns security by default at smaller companies |
A company that sells managed IT rather than security is on the IT services page; software with a security feature starts at the software companies page. More on this vertical: the Sales.co cybersecurity companies page.
Lists the campaigns are built from
| List | Contacts | Used for |
|---|---|---|
| Companies Using Snowflake | 8,500 | Access control, data classification, exfiltration monitoring. |
| Companies Using Workday | 15,000 | Identity angle: joiner-mover-leaver, entitlement review, SaaS identity sprawl. |
| Companies Using SAP | 38,000 | A proxy for the size and audit obligations to buy security tooling at all. |
| SaaS Companies | 52,000 | Software firms that answer a security questionnaire to close their own deals. The best pool for compliance-led offers. |
| Healthcare Lists | 374,800 | Regulated buyers you may sell into. We build security contacts inside them rather than mailing clinicians. |
| Lawyers | 105,224 | Client-confidentiality obligations and, at mid-size, no security team. |
| Financial Advisors | 49,200 | Regulated, small, and usually outsourcing security entirely. |
There is no CISO list. The security-buyer list is built to order, and the stack lists below narrow the companies before anyone looks for people.
