If you are 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.

The order above is the general editorial ranking. Re-sorted against best published rate per 1,000, developer experience, and operating track record, the shortlist for a waitlist, a launch announcement, onboarding email, and the first transactional sends becomes Customer.io, Loops, and Klaviyo. That differs from the headline order, which weighs all audiences together.
