Brevo

Brevo (rebranded from Sendinblue in 2023) is a French-founded all-in-one marketing platform that bundles email marketing, SMS, WhatsApp, a built-in CRM, marketing automation, transactional email and SMTP, landing pages, signup forms, and meeting scheduling under one platform. The pricing model differs structurally from most US-based competitors: contacts are unlimited at every tier; you pay only for emails sent, which makes Brevo unusually cheap for email lists with low send frequency (newsletters, monthly broadcasts) and competitive for higher volume too. Marketing automation supports visual workflows with conditional branching; the CRM handles lead capture, deal pipelines, and basic sales tasks; transactional email and SMTP cover developer use cases that compete with Postmark, SendGrid, and Mailgun. Brevo positions against Mailchimp (US incumbent, contact-based pricing), Klaviyo (ecommerce-vertical specialist), ActiveCampaign (deeper automation, US-focused), GetResponse (similar all-in-one positioning), Constant Contact (US SMB legacy), and MailerLite (cheaper but lighter). The differentiator is the unlimited-contacts pricing model + multichannel breadth (email + SMS + WhatsApp + transactional) at SMB price points.
