Brevo grew out of Sendinblue (founded in Paris in 2012) with roots in message delivery and reliability constraints. Mailchimp started in Atlanta in 2001 as a side project inside a web design agency, built to replace bulky email software.
Because Brevo formed around sending infrastructure, it prioritizes throughput, channel coverage, and system controls around delivery. This leads to more attention on limits, throttling, and account-level safeguards, with less emphasis on a single polished creation flow. One concrete sign is its long-standing positioning around transactional email and deliverability alongside campaigns.
Because Mailchimp began as an agency-built product meant to be an approachable alternative to enterprise email tools, it prioritizes a guided workflow and consistent defaults. This leads to stronger guardrails and opinionated setup choices, which can reduce flexibility in edge cases. One visible outcome is the sustained investment in template-driven content building and tightly integrated campaign surfaces.
Those origin choices still shape how each platform feels when requirements get complex or scale quickly. The next sections surface how these early priorities translate into practical differences across the product.
