See what an email campaign — and each subscriber — is worth.

Work down the funnel: subscribers times open rate gives openers, times click rate gives clickers, times conversion rate gives buyers; buyers times average order value gives revenue. Divide that by the number of subscribers and you get revenue per subscriber for a campaign. It's a simple but powerful figure — it tells you what a signup is worth, which sets how much you can spend to grow the list.

Both help, but they scale differently. Growing the list multiplies revenue linearly, while improving open, click, or conversion rates lifts the value of every subscriber you already have — often the cheaper win. If your rates are weak, improving them can be more profitable than chasing more subscribers; if your rates are strong, growth compounds their value. This calculator lets you test each lever so you invest where it pays off most.
