The full feature matrix for team email
Receive, thread, compose, collaborate, measure, and generate — Nestiel plugs into your own domain and Resend account, and replaces a stack of tools with one integrated workspace.
Receive & threading
Inbound email arrives structured; exchanges become threads.
Inbox
Auto-pulls new mail every minute, with one-click manual sync and unread highlighting.
Automatic threading
Plus-tag and References together land replies back in the right conversation.
Sent & delivery timeline
Every sent email carries a delivered / clicked / bounced event timeline.
Full-text search
Fuzzy match across sender, recipient, cc, bcc, subject, and body, with highlights and direct jumps.
Compose & send
From a single reply to per-recipient bulk send — cadence and content under your control.
Rich-text editor
Rich text, attachments, inline images, and recipient autocomplete.
AI email drafting
Sparkles entry in the editor toolbar drafts subject and body from conversation context and your personal prompt.
Reply / Reply all / Forward
Auto-fills recipients, quotes the original, links to the conversation; forwarding carries attachments and inline images.
Separate sending & send tasks
Each recipient gets a standalone email; the send-task panel tracks every row, pause and resume anytime.
Tunable send cadence
Separate sending and personal-at-scale share the same rhythm: a tunable 1–10 minute interval that protects deliverability.
Scheduled send
Set a future send time for compose, reply, or separate sending; a background scan triggers delivery.
Auto-saved drafts
Compose and replies auto-save (~1.5s debounce) with attachments, inline images, and send settings.
Collaboration & roles
One deployment hosts many orgs, shared inboxes, and role tiers.
Multi-tenant orgs
One deployment hosts many orgs, each with members and mailboxes, strictly isolated.
Shared inbox
Attach support@ or sales@ to an org and let the whole team work them.
Roles & permissions
Admins configure the org, keys, and invites; members focus on their own inboxes.
Inbox context switching
A user can hold several inboxes in an org and picks the context before acting.
Insight & AI
Deliverability health plus the AI email trio — all in the same workspace.
Deliverability health
KPIs, trends, a funnel, and top bounce reasons over 7 / 30 / 90 days; visibility scoped by role.
AI email translation
Translate each new body in a conversation into a target language in one click — quoted history stripped, plain text appended below.
AI email drafting
A sparkles entry in the compose toolbar drafts and polishes from context into a ready-to-send subject and body.
Personal at scale
At /personalized, generate distinct subjects/bodies per recipient, review row by row, and dispatch via separate sending.
Custom org LLM
Configure an OpenAI-compatible model at the org level (API key, base URL, model name) — shared across every AI capability.
Frequently asked questions
What core email capabilities does Nestiel cover?
A shared inbox, automatic threading, AI drafting, per-recipient personalization, separate sending with a send-task panel, scheduled send, auto-saved drafts, deliverability health, full-text search, translation, and forwarding — receive, collaborate, measure, and AI in one workspace instead of a stack of tools.
How does automatic threading work?
Outbound mail embeds a plus-tag (a +conv-<id> in Reply-To) and a References token; replies are woven back into the original conversation automatically, with no manual sorting.
How is separate sending different from a normal blast?
Separate sending gives each recipient their own standalone email (not one message cc'd to a crowd), delivered on a tunable 1–10 minute cadence and tracked row by row in a send-task panel you can pause and resume.
Can a team share one mailbox?
Yes. Attach support@ or sales@ to your org, grant access to everyone or a named list, and members share sending, search, drafts, and scheduling — with conversation state synced across the team.
