8 tools in Email Copy, with monthly plans running from $9 to $100 — an 11-fold spread for products that describe themselves in much the same words.
3 have a free tier rather than a trial (beehiiv, Brevo and Mailchimp), and Shopify Sidekick publishes no price at all.
They do not meter the same way — this page mixes fixed plans, quotes, a parent subscription and a calculator — so compare what a price buys before comparing the price.
