Post #3591618

Upyo 0.5.0 is out: a cross-runtime email library for #JavaScript and #TypeScript, one Transport API across SMTP, JMAP, Mailgun, SendGrid, SES, Resend, Plunk, and now Lettermint. This release makes failed sends structured (category, retryable, HTTP status, Retry-After) instead of just a string, adds a retry transport with backoff and jitter, and brings OAuth 2.0 to SMTP for Gmail and Outlook. https://github.com/dahlia/upyo/discussions/29
