Overview
Resend is an email delivery platform built for developers, offering an API and SDKs to send transactional and marketing emails from applications.

The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Resend.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.
