Changelog

Notable changes to Plume.

v0.2.0 — 2026-07-03

• SMTP email provider — send through Mailgun, SendGrid, Postmark, Resend, or any SMTP server; no AWS account required. Choose the active provider (SES or SMTP) in Settings → Email. One-click unsubscribe headers are preserved on the SMTP path; bounce/complaint auto-suppression remains SES-only for now. See Email providers.
