Best Resend Alternatives
Resend has become the default answer for developer email: a clean API, React Email templates, and a free tier that gets you shipping in an hour. But it isn't the only answer — you might want a longer deliverability track record, transactional and marketing under one roof, or an open-source stack you control. These are the developer-oriented senders worth weighing instead.
