What you pay at 10k — not the homepage sticker.
Kit free still covers 10,000. beehiiv free stops at 2,500. MailerLite/Mailchimp free are 250–1k. Slider sorts cheapest → dearest.
Green = still free at this size. Grey = unverified or intentional blank (See vendor / No annual price listed — linked). “Contact sales” / “Custom” = vendor hides public list pricing. Sorted cheapest → dearest.

How the numbers stay honest
Comparison blogs invent “$29 at 5,000” from outdated screenshots. We only publish figures we can point to on a vendor pricing or help page. If a slider is JS-only and we couldn’t verify a tier, the cell is unknown — not guessed.
