Brevo

Brevo (formerly Sendinblue) is an all-in-one platform that bundles email, SMS, push notifications, and CRM into a single interface. Its send-volume pricing model scales with business growth, making it cost-effective for companies ranging from startups to enterprise. The platform includes built-in automation workflows, segmentation tools, and transactional email capabilities alongside marketing campaigns.

Brevo works well for B2B companies needing multi-channel campaigns without juggling separate vendors. It's particularly strong for businesses that want both marketing automation and transactional email in one place, though it lacks the specialization of platforms built exclusively for one channel.
