Sender vs Brevo
Generous free marketing plan versus broader all-in-one email, CRM, and SMS coverage.
What matters for developers picking email infrastructure
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.

| Free tier | Free forever for 2,500 subscribers and 15,000 emails/mo | 300/day permanent |
For a developer-owned stack running password resets, receipts, and magic links shipped from application code, Brevo takes every priority that separates them here (developer experience and SDK breadth), while Sender matches it on the rest. On free tier, Sender offers Free forever for 2,500 subscribers and 15,000 emails/mo against 300/day permanent from Brevo. That ordering reflects this audience. Weigh the same table differently and the answer changes.
