Buttondown

Buttondown is a newsletter publishing service for writing emails and managing a subscriber list. It supports free publications and paid newsletter subscriptions. Monthly plans grow with the number of subscribers.

The published allowance covers up to one email per day to the full list. Automations become available on plans costing at least $29 a month, and branding removal has a higher threshold. Publishers with very large lists or a more frequent sending schedule need a separate quote.
