Reviewers describe Resend as a simple, developer-first way to handle transactional email, with fast setup, clean APIs, clear logs, and strong deliverability. Users repeatedly say integration takes minutes and removes the usual email maintenance burden, especially when paired with React Email or serverless tools. Makers of
Refgrow and
Rectify say they use it for onboarding, alerts, notifications, and support replies because it “just works.” Complaints are limited but real: sparse Python examples, some missing marketing or unsubscribe features, domain setup friction, and one report of serious delivery delays.
