How many leads do you need for cold outreach?

A typical B2B outbound campaign needs between 300 and 1,000 verified leads per month per salesperson. With verified inboxes and warm why-they-fit notes, expect 15–30% open rates, 3–8% reply rates, and 1–3 closed deals per 500 leads depending on offer economics.

The short answer

Most B2B service agencies and contractors need between 300 and 1,000 verified leads per month. Sourcing 10 to 35 verified decision-makers per working day allows you to run targeted, multi-touch email sequences without burning domain reputation or tripping spam filters.

The outbound conversion funnel math

Outbound success is a numbers game governed by data quality. Here is the realistic math for a campaign built on 500 4-step verified leads:

Delivered Leads: 500 verified decision-makers.
Open Rate (60–75%): ~325 opens (driven by clean sender reputation and verified MX records).
Positive Reply Rate (3–6%): 15 to 30 qualified conversations.
Booked Discovery Calls (30–50% of replies): 5 to 12 scheduled meetings.
Closed Clients (15–25% close rate): 1 to 3 new paying clients.

If your average customer value is $2,500, a $49/month Scale plan (1,000 leads) can easily yield a 50x return on investment.

Inbox capacity and domain safety

Sending 500 emails a day from a single inbox is a fast way to get blacklisted. Industry best practice is to send no more than 30 to 45 emails per day per sending inbox, using 2 to 3 secondary domains. That is why LeadFinder offers tiered subscriptions matching exact team sending capacity: Pro (300/mo) for single-inbox operators, Scale (1,000/mo) for 2–3 inboxes, and Growth (7,000/mo) for dedicated sales teams.
