Mailchimp vs Brevo
Recognizable marketing suite versus broader budget-friendly marketing and transactional email.
What matters for SaaS product teams
A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.

For a multi-tenant SaaS product running trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail, the two are level on every priority that can be scored here, so the choice comes down to price and to which product your team would rather operate. On entry price, Mailchimp / Mandrill offers $13/mo Essentials against $9/mo for 5,000 emails from Brevo. That ordering reflects this audience. Weigh the same table differently and the answer changes.
