About

Brevo is a full email marketing and transactional-email platform whose free tier is one of the most generous around: 300 emails a day (about 9,000 a month), unlimited contact storage, and no credit card required. Beyond the API it has drag-and-drop newsletter templates, automation workflows, and CRM features, so a small business can run both one-off emails and newsletters from one free account.
