Cheapest plan on each platform that covers the list size and needs. Paid totals = plan + platform cut + Stripe card fees (2.9% + $0.30 per payment, estimate) + Stripe's 0.7% Billing fee on recurring payments where confirmed (beehiiv, MailerLite, Ghost, Buttondown, Substack, AWeber and Flodesk); not added for GetResponse (not confirmed); Kit's 3.5% + $0.30 is all-in. How we model fees. "limited" = feature capped on that plan.

What you'd give up

Cost isn't everything. What Mailjet does well, from its official pages: Senders who think in email volume rather than list size, or who want transactional email (API and SMTP) and marketing email in one account.
