Mailjet alternatives
Providers that compete with Mailjet on at least one of: Transactional Marketing
European-focused, GDPR-friendly all-in-one.
Switching as early-stage startups
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
Mailjet already covers what this audience leans on, so the list below is about price, ergonomics, and consolidation rather than closing a capability gap.
