Brevo is a customer engagement platform for email, SMS and WhatsApp messages. It was founded in 2012 by Armand Thiberge in India and France, and the companies of the Brevo group include Sendinblue SAS and Sendinblue, Inc.
It covers two kinds of email. Marketing campaigns go to a list of contacts: a drag-and-drop editor and templates build the email, segmentation selects the recipients by attributes, website activity and events, and marketing automation runs multi-step workflows that send a message when a contact does something. Transactional messages, such as a password reset or an order confirmation, go to one person at a time and are triggered by the business's own software through an SMTP relay (a mail server that accepts email from an application) or an API. Brevo also includes a CRM for sales pipelines, live chat and AI agents.
Brevo is a hosted service. It has a free plan; paid plans are monthly or yearly subscriptions priced by the number of emails sent each month.
