Cold email agency for seed-stage SaaS startups
Sales.co runs done-for-you cold email for B2B SaaS companies. Two audiences matter most at that stage: people at other software companies, and department heads who can approve a tool on their own. Between March and August 2026, 63,544 people at software and SaaS companies got a first cold email from campaigns on the Sales.co platform, and 0.31% replied positively. Among VPs and directors at companies of 11 to 500 staff it was 0.26%.
How software buyers and department heads 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.

|---|---|---|---|---|
| All contacts in the 20 campaigns | 336,257 | 2,830 | 975 | 0.29% |

| VP and director level, companies of 11 to 500 employees | 58,288 | 461 | 152 | 0.26% |
One campaign supplied 45,696 of the 63,544 contacts (72%) and 96 of the 198 positive replies, a rate of 0.21%. The other 17 campaigns together got 102 from 17,848, or 0.57%.
At software and SaaS companies, by company size

|---|---|---|---|---|
| 1 to 10 | 22,753 | 274 | 96 | 0.42% |

| 5,001 and up | 450 | 0 | 0 | 0.00% |
| No size on file | 1,049 | 32 | 17 | 1.62% |
Software companies of up to 50 people replied positively 0.32% of the time (146 of 45,081). Above 500 employees it was 4 of 3,541. Small companies decide quickly and sign small contracts, so the small end pays only if the entry price makes a meeting worth it.
At software and SaaS companies, by department
| Department | Contacts | Replied in person | Positive reply | Positive rate |
|---|---|---|---|---|
| Executive | 42,960 | 380 | 136 | 0.32% |

Who Sales.co emails for a SaaS company
| Segment | Who gets the email |
|---|---|
| Seat-level and team deals | The department head who owns the budget line: VP Marketing, Head of RevOps, Director of Engineering, VP Finance, at companies of 20 to 500 staff |
| Platform and enterprise deals | CTO, CIO, VP Engineering, VP Data, Chief Product Officer, plus the security reviewer who arrives after the first meeting |
The first question on the kickoff call is the average contract value, because the title that signs a five-seat deal will not sign a platform contract. More on this vertical: the Sales.co seed-stage SaaS startups page.
Lists the campaigns are built from
| List | Contacts | Used for |
|---|---|---|
| SaaS Companies | 52,000 | The base list when you sell to software companies, filtered by size and by the stack signals below. |
| Companies Using Stripe | 45,000 | For anything downstream of billing: revenue reporting, dunning, tax, finance ops, pricing. |
| Companies Using Snowflake | 8,500 | A company with a warehouse in production has a data team, a budget, and an integration surface you can name. |
| Companies Using Capterra | 12,000 | Software vendors paying for review-site distribution: a marketing budget already committed. |
| Newly Funded Startups | 19,344 | A trigger, not a fit filter. A company that just raised is buying and replacing tools this year. |
| Series A Startups | 4,260 | The stage where a first RevOps or security hire happens. Good if your product gets bought right after that hire. |
| Seed Startups | 8,820 | Quick to decide, small contracts. Worth it only if your entry price makes the meeting pay for itself. |
Employee count, installed tech stack and funding stage each produce a different list.
