Automated email briefings, every morning and evening
Spend less time managing your inbox.
NocturnalPost organizes your email and delivers scheduled briefings of what matters — who needs a reply, what's overdue, what broke. Connect Microsoft 365, Outlook, Gmail, Google Workspace, or any supported IMAP mailbox. Privacy-first by design: your mail is summarized and forgotten, not warehoused.

Operations & support
Client escalations and vendor emails get surfaced as follow-ups automatically — nothing waits until someone remembers to check.
MSPs & accounting
Every client domain gets its own isolated tenant. Briefings keep each account's commitments visible without a project-management suite.
Legal, lending & nonprofits
Compliance-friendly: metadata-first storage, 30-day default retention, tokens encrypted, delete and export built in.
How it works
Connect
Sign in with Microsoft and pick your Inbox folder. Granular, user-approved access — no tenant-wide mailbox crawling, ever.
Classify
Every message is categorized — urgent, needs-reply, routine, automated — and actionable mail becomes a tracked work item.
Brief
Dawn Brief in the morning, Dusk Brief in the evening, weekly Moon Brief. Delivered by email, or posted to a Teams channel.
Forget
The Vault enforces retention on schedule. Your team's week stays visible; the mail itself ages out. Ask it anything with semantic search while it's live.
Short-lived email intelligence
Nocturnal Post is built on a simple promise: the data it derives from your email is treated as carefully as the email itself. Message metadata and previews only. Per-tenant databases. Encrypted OAuth tokens. Configurable retention with a 30-day maximum default. One click to disconnect and revoke — Microsoft tokens included.
