Is cold outbound email profitable for your business? Let's find out.
I built a simple calculator that shows you exactly:
↳ How many emails you need to send.
↳ How many inboxes to buy.
↳ How many emails to send/day/inbox.
↳ How many inboxes per domain.
↳ What your tech stack will cost.
↳ If your campaigns will be profitable.
This isn’t theory. It’s the same math we use inside NextGen Sales Systems to manage over 100 cold outbound campaigns every month.
Here’s what most people don’t realize:
You can easily spend $4,000 to $12,000 per month on cold email before you even book a single meeting.
❌ Sending too many emails per inbox gets you blacklisted
❌ Buying the wrong data gets you bounced emails
❌ Skipping AI copy and enrichment kills conversions
The math doesn't work unless:
1. You have a big total addressable market.
2. Your offer is clear and concise, easily stated in one sentence.
3. Your price point is $10K or more.
4. Your lifetime value is over $20K
I walk through everything in the spreadsheet:
✅ Reply rates you need
✅ Total inboxes to buy
✅ Expected software costs
✅ How your "reply rates" affect your total meeting volume
✅ When your total market size kills your campaign before it starts
