Loops vs Brevo
Focused SaaS lifecycle email versus broad SMB marketing, transactional, 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 | 1,000 contacts and 4,000 sends/mo on the Free plan | 300/day permanent |
For a developer-owned stack running password resets, receipts, and magic links shipped from application code, Brevo takes SDK breadth and operating track record, while Loops takes developer experience. On free tier, Loops offers 1,000 contacts and 4,000 sends/mo on the Free plan against 300/day permanent from Brevo. That ordering reflects this audience. Weigh the same table differently and the answer changes.
