Frequently asked questions
A cold email ROI calculator estimates how much revenue your outbound email campaigns will generate compared to their cost. This calculator goes further: it models the ramp-up period, compares cold email to other channels, and generates a business case you can present to your team.
The default open rates, reply rates, and meeting rates are based on aggregated data from outbound campaigns across each industry. SaaS B2B typically sees 45% open rates and 3.2% reply rates, while Agency/Services sees lower opens (38%) but higher replies (5.1%). You can adjust every number to match your own data.
Two reasons. First, new email domains need 2-4 weeks of warmup before you can send at full volume. Second, your sales cycle means the first meetings from month 1 outreach won't close until month 2-3. This ramp-up is built into the projection so you get a realistic picture, not an inflated one.
The table uses the same annual budget across all channels. For each channel, we apply industry-average Customer Acquisition Cost (CAC) to calculate how many deals that budget would generate. CAC data comes from published benchmarks for Google Ads, LinkedIn Ads, and SDR hiring costs by industry. Cold email typically has the lowest CAC because infrastructure costs (domains + mailboxes + tool) are minimal relative to output.
Yes. All results, the funnel, revenue chart, and channel comparison are 100% free with no signup. The PDF export asks for your email so we can send you the business case document.
The infrastructure section calculates this automatically. The rule: each mailbox sends max 50 emails/day, each domain hosts 2 mailboxes, and there are 20 working days per month. For 2,000 prospects with a 3-email sequence, you need about 6 domains and 12 mailboxes.
