Email Send Frequency

The right cadence, before the unsub fatigue sets in.

A free email calculator from AMA Orlando, the American Marketing Association chapter serving Central Florida. It runs in the browser, needs no login, and captures nothing.

What you enter

• List size
• Open rate
• Unsubscribe rate per send

How it is calculated

• Suggested sends per month is stepped from the open rate, since engagement is what earns the right to send more
• Estimated monthly unsubscribes = list size × unsubscribe rate × sends per month
• Projected list in 90 days = list size minus (monthly unsubscribes × 3), assuming no new signups

How to read the result

Frequency is not a fixed number, it is a function of how engaged the list already is. A highly engaged list tolerates and rewards more sends; a tired one shrinks faster than acquisition can refill it. The 90 day projection is deliberately pessimistic because it assumes a replacement rate of zero.
