Most email tools charge rent on every contact you store. We charge postage on the emails you send. Put in your numbers and see a year of both.
That's 10,000 emails a month, 120,000 a year.

How we worked this out
- Flatstamp: the cheapest mix of stamp packs that covers a year of sends. One stamp, one email.
- Everyone else: their cheapest plan that fits your list and monthly sends, at the list price on monthly billing, in US dollars, before tax and discounts. Annual billing is often cheaper.
- Where we couldn't confirm a price step, we show a range rather than guess in our favor. Free plans count: if one covers you, we say so.
- Prices checked October 21, 2026. They change; each comparison page lists our sources.
