How to calculate cold email ROI. A simple framework that actually works

My boss kept asking about cold email ROI and I never had a clear answer. Built this framework and now I can justify our budget with real numbers.
Step 1: Calculate total monthly cost.
- Inboxes (e.g., 20 inboxes × $4.50/inbox = $90)
- Sending platform (e.g., Instantly = $30)
- Data provider (e.g., Apollo = $50)
- Verification tools (e.g., NeverBounce = $20)
- Your time (e.g., 10 hours/month × your hourly rate)
- Total example: $190 + 10 hours of time
Step 2: Calculate pipeline generated.
- Emails sent per month: 400/day × 22 working days = 8,800
- Reply rate: 3.5% = 308 replies
- Positive reply rate: 40% of replies = 123 positive replies
- Meeting conversion: 50% = 62 meetings
- Deal conversion: 15% = 9 deals
- Average deal value: $5,000
- Revenue generated: $45,000
Step 3: Calculate ROI. ROI = (Revenue - Cost) / Cost × 100. In this example: ($45,000 - $190) / $190 × 100 = 23,584% ROI. Even if you are conservative and cut these numbers in half, the ROI is still absurd compared to paid advertising.
Present it to leadership as: "For every $1 we invest in cold email infrastructure, we generate $237 in revenue." This is the language executives understand. Cold email is the highest ROI B2B lead generation channel when done properly.

23,584% ROI. I love it. even if you cut everything in half and assume way worse conversion rates it's still 10,000%+ ROI. no paid channel comes close. I use similar math to justify my cold email budget every quarter and leadership never pushes back

the framework is great but I'd add one thing: include the cost of burned domains in your ROI calc. if you're rotating 5 domains/month that's an extra $60/year in domain costs plus the inboxes you lose. it's still insane ROI but the real cost is slightly higher than $190/month

the framing as 'for every $1 invested we generate $X in revenue' is exactly how you present this to executives. they do not care about reply rates or open rates. they care about dollars in vs dollars out. always translate email metrics into revenue language when talking to leadership

how do you account for the time cost? like if an SDR spends 10 hours/month managing campaigns, that's real labor cost. does it still make sense if you factor in a full salary?
