# Email platform cost calculator

How much does email marketing cost? Compare a typical email platform at your list size with Mimeo plus your own Postmark or Resend account.

## How to use it

1. Drag the slider to your list size, from 1,000 to 200,000 subscribers.
2. Pick how often you send: twice a month, weekly or daily. The calculator turns that into emails a month.
3. Pick a sending provider, Postmark or Resend, and read your total: the Mimeo license once, plus your provider's monthly bill.

## A worked example

At 15,000 subscribers sending weekly, the calculator counts 90,000 emails a month. Resend's plan for that volume is shown as the monthly sending bill, beside the Mimeo license once. The typical email platform figure beside it is the average of published Kit and Klaviyo pricing at the same list size, billed monthly.

## Questions

### How many emails a month should I count?

Your list size times the emails each subscriber gets in a month: newsletters plus automated flows. The calculator assumes 3.5 a month for twice-monthly sending, 6 for weekly and 32 for daily.

### What isn't in the total?

Your server, and support & updates renewals after the first year. The savings compare sending costs with a typical email platform and leave out the license.

### Is anything sent to a server?

No. The calculation runs on this page in your browser.
