Both are modern email APIs. Here's where they differ.
Resend is a clean email API with good developer experience. MailFabric matches that DX and adds template versioning, approval workflows, and a built-in delivery guide. If you need multi-tenant support for a platform product, MailFabric is the only option.

Choose Resend if you want a minimal email API and don't need template versioning or multi-tenant features.
Choose MailFabric if you want version-controlled templates, an AI delivery guide, or you're building a platform where your customers need to send email.
