Brevo (formerly Sendinblue) is the most direct answer to Mailchimp's biggest pain point: it bills by emails sent, not by number of contacts. If you have a large list you email occasionally, that flips the economics entirely — you can store unlimited contacts and pay only for volume. On top of that you get SMS, WhatsApp, a built-in CRM and transactional email. The trade-offs are daily send caps on lower tiers and templates that aren't as slick as Mailchimp's. But for anyone whose Mailchimp bill exploded as their list grew, Brevo is the switch that stops the bleeding. It imports contacts easily.
