The record

Product: Pelton is a free, open-source desktop email client that stores mail on your computer and with your email provider.
Offline search: Pelton uses a local Bleve full-text index to search downloaded mail without a connection.
Retention: Users choose how far back to keep downloaded mail and can pin individual messages permanently.
Encryption: Pelton supports PGP and S/MIME signing, encryption, decryption, and verification; key handling stays local and both features are off until enabled.
Sender checks: Pelton displays SPF, DKIM, and DMARC results and checks for spoofed names, off-domain Reply-To addresses, and lookalike domains.
Email protocols: Pelton uses IMAP and SMTP and says it works with most email providers; Gmail OAuth2 requires Google Cloud credentials created by the user.
Controls: Pelton includes snooze, scheduled sending, saved views, reading tabs, customizable shortcuts, and native notifications.
Privacy: The app says it makes no requests to Pelton-run servers, has no telemetry or automated crash reports, and blocks remote images by default.
Agent connection: Pelton’s local MCP server is off by default, binds to 127.0.0.1, starts read-only, and lets users grant write actions individually.
Agent sending: Even when sending is granted, an agent can queue a draft for the user to approve, and attachment contents remain on disk.
Platforms: Downloads are listed for macOS Apple Silicon and Intel, Windows, and Linux; the site says there is no mobile version yet.
Not a backup tool: The download page says Pelton is not a backup tool and warns that deletion can be permanent.
Builds: The download page says the builds are not code-signed, so macOS and Windows may require users to confirm opening them.
Maker: The imprint identifies Stellar Foundry GmbH in Bonn, Germany, as the provider.
Price from: Free
