Lead generation calculator: how many meetings your cold email will book

By , co-founder of Sales.co. Updated October 22, 2026. Rates from the Sales.co conversion rate benchmarks (336,257 contacts, 20 campaigns).

At the median campaign in Sales.co's benchmark data, 10,000 cold emails a month reach about 5,360 contacts and bring about 6 positive replies and 3 booked meetings: $702 per meeting at $2,000 a month. Pooled across all 20 campaigns, the same volume brings 15.5 positive replies and 7.5 meetings. Change any number below to run your own.

What this calculator adds: every rate is prefilled from real B2B sending. The reply rates come from 336,257 contacts in 20 campaigns (first emails March 6 to August 31, 2026), and the booking and close rates from Sales.co's own campaign, followed from first email to booked call to paying customer.

Cold email lead generation calculator
First emails and follow-ups together. Sets the two reply rates below from our data. The campaign presets come from the 15 campaigns with 5,000+ contacts; the company size and seniority presets are pooled across all 20. Edit the rates to use your own.
Per contact; per email the rates are lower, because most contacts get more than one email. A personal reply is one written by a person; positive means interested, a question, "later" or a referral.
1.865 is the 20-campaign average (627,085 emails to 336,257 contacts). 0.483 is Sales.co's own campaign: 143 booked calls for 296 positive replies.
4.9% is Sales.co's own: 7 of 143 booked calls had paid by October 6, 2026 (95% interval roughly 2% to 10%). $10,000 is an example: use your first-year revenue per customer. Sales.co: $2,000 for up to 10,000 emails, $2,500 for 15,000, $3,000 for 20,000 a month. In-house, add tools, data and the hours.

Your personal reply rate of 0.65% matches the median campaign (0.65%), among 15 campaigns with 5,000+ contacts.

Check: Sales.co's own campaign measured one booked call per 1,650 emails, which would be 6.06 meetings at this volume.

Bookings lag: the median call came 9 days after the first email, and 34% came more than 30 days later, so the first month books fewer.

The rates behind the calculator

Every default is a rate measured in Sales.co's data, per contact. The calculator starts at the median campaign because the pooled average is pulled up by four strong campaigns: the median got a positive reply from 0.11% of contacts, the pooled figure is 0.29%. The reply rates are per contact: a per-email rate falls as you add follow-ups even when the same people reply, so the person is the steadier base for planning. The presets change with company size and seniority because both move reply rates a lot in our data, from a 0.48% positive reply rate at companies with 1 to 10 employees to 0.07% at 1,001 to 5,000.

Source: Sales.co cold email conversion rate benchmarks, 336,257 contacts and 627,085 emails in 20 B2B campaigns, first emails March 6 to August 31, 2026, replies counted through October 6, 2026. Raw rows: CSV.

The steps after the reply come from Sales.co's own campaign, the one campaign where we see every booking. It had 124,513 contacts, 296 positive replies and 143 companies that booked a call, and 7 of those had become paying customers by October 6, 2026. That gives 0.48 meetings per positive reply and a 4.9% close rate. The 0.48 includes 42 bookings from companies whose contact never replied, so it is a ratio of meetings to positive replies, and the share of positive repliers who book is lower.

The campaign rows are quartiles: a top-quarter campaign got a personal reply from 0.94% of contacts or more and a positive reply from 0.51% or more. The company size and seniority rows are pooled within each group, so like the pooled total they sit above what a typical campaign in that group gets.

How many emails a meeting target takes

Ten booked meetings a month take about 35,100 emails at the median campaign's rate and about 13,400 at the pooled rate: 10 meetings ÷ 0.483 meetings per positive reply ÷ the positive reply rate per contact × 1.865 emails per contact. Run the same steps with your own numbers in the calculator: raise the email volume until the meetings line reads your target.

Median campaign: 0.11% positive replies per contact; pooled: 0.29%; both with 1.865 emails per contact and 0.483 meetings per positive reply. Prices from sales.co/pricing, read October 22, 2026.

Sales.co's own campaign landed between the two: one booked call per 1,650 emails, so 10 meetings took about 16,500 emails there, at a 0.24% positive reply rate. Plan on the median and treat the pooled figure as the good case.

Limits: when these numbers won't hold

The strongest case against the defaults: they come from campaigns Sales.co wrote and sent, on lists we built and checked, so a team starting from a bought list and a new domain can land well below them. The spread is wide even inside our data: a bottom-quarter campaign got a positive reply from 0.06% of contacts or less, under a tenth of a top-quarter one. For a first campaign, run the bottom-quarter preset next to the median.

Three more limits. The booking and close rates come from one campaign, Sales.co selling its own service, with 143 bookings and 7 customers behind them. The close rate's 95% interval runs from roughly 2% to 10%, and it is a floor, because the companies that booked in August and September had only a few weeks to decide. Your offer, price and sales process set your own close rate, so replace the 4.9%. A meeting here is a booked call (cancelled bookings removed): we do not measure how many were held. And bookings arrive late: 34% came more than 30 days after the first email, so a single month of sending shows fewer meetings than the calculator, and the second month more. At the median campaign and the 4.9% close rate, a customer has to be worth about $14,300 before a $2,000 month pays for itself (the cost per customer row). Change the value of one customer to see where yours lands.

FAQ

How do you calculate how many leads you need?

Work backwards from the meetings or customers you want. Divide the meetings you need by the share of positive replies that book, then by the positive reply rate per contact, then multiply by the emails each contact receives. At the median Sales.co campaign, 10 booked meetings a month take about 35,100 emails; at the pooled rate, about 13,400.

How many cold emails does it take to book a meeting?

In Sales.co's own campaign, one booked call per 1,650 emails sent (143 bookings from 235,941 emails to 124,513 contacts, March to August 2026). At the median campaign's positive reply rate it is about one meeting per 3,500 emails, and at the pooled 20-campaign rate about one per 1,340.

What is a reasonable cost per lead for cold email?

At $2,000 a month for 10,000 emails, a positive reply costs about $339 at the median campaign and $129 at the pooled 20-campaign rate; a booked meeting about $702 and $267. A bottom-quarter campaign pays about $622 per positive reply.

What is a good cold email reply rate?

Among Sales.co campaigns with 5,000+ contacts (March to August 2026), the median got a personal reply from 0.65% of contacts and a positive reply from 0.11%; the top quarter reached 0.94% and 0.51% or more. Pooled across all 20 campaigns: 0.84% and 0.29%.

Why does the calculator count contacts instead of emails?

Replies come from people, and each person gets a first email plus follow-ups. In the 20 campaigns each contact received 1.86 emails on average, so 10,000 emails reach about 5,360 people. A per-email rate falls as you add follow-ups even when the same people reply, so per-contact rates are the better base for planning.
