Every time a price in our calculator changes, it is recorded here with the date and source. We re-check every platform at least once a month.
Last full check: .
First full check of official pricing pages for Substack, beehiiv, Kit, Ghost (Pro), Buttondown and MailerLite, plus Stripe's US card rate. Prices that could be read on official pages are marked verified. Tier prices that the official pages only show inside interactive sliders were taken from dated third-party write-ups and are marked unverified until confirmed.
These happened before our first check. They come from third-party reports (linked) and are listed for context only.
beehiiv renamed its plans (Free / Lite / Pro / Enterprise) and raised prices for new customers; existing customers reportedly move over at their first renewal on or after 2026-11-01.
