Email Marketing calculators

Use these tools to estimate list value, email ROI, sponsorship income, unsubscribes, and revenue tied to broadcasts.

Recommended workflow

Model revenue per send with opens and clicks defined the same way your ESP exports them.
Estimate sponsorship fees with conservative open rates—sponsors care about fit as much as size.
Track unsubscribe rate against delivered volume when cadence or topic changes.
Compare ROI against labor and tooling cost in the same month you attribute revenue.

Monthly planning value from subscribers × average monthly revenue each monetized subscriber contributes.

Estimated ROI comparing email-attributed revenue with the cost of running email marketing.

Rough dollars per broadcast from subscribers, opens, clicks among openers, and dollars per outbound click.

Approximate sponsorship fees from reachable opens × CPM with monthly send cadence baked in.

Unsubscribes ÷ emails delivered × 100 for specific campaign batches.
