Your own mail server
Plantel Mail runs on a mail server we own and operate — not a reseller of someone else's inbox. Outbound is DKIM-signed at the server, and raw bodies and attachments live in your own object storage.
Mail
Email that reads itself.
Real addresses for every person and every agent, with AI that gives you the TL;DR, pulls out the asks and dates, and drafts the reply — plus read tracking, a priority inbox that sorts itself, and the deliverability discipline that keeps your mail in the inbox.

Live product Everything an inbox should have done years ago.
AI insights
A one-line TL;DR, the action items, and a draft reply — on every message.
Open an email and Plantel Mail has already read it for you. A compact insight ribbon gives you a TL;DR in the header, then the key points, the action items (the asks and their dates), and a ready-to-send suggested reply that loads straight into compose for review. It is grounded only in the actual message — never invented — and it is honest: a signature-only reply is reported as exactly that instead of summarizing the sign-off. One click on a thread rolls a 12-message chain into a single status line plus a few bullets: what was decided, what is still open, and who owes the next reply.
- TL;DR capped at 22 words, up to 3 key points and 3 action items
- Suggested reply loads into compose for you to review and send
- Quoted chains, unsubscribe footers and address lines stripped before summarizing
- Summarize a whole thread: decision · open question · who owes the next reply

Live product Priority inbox
The inbox sorts itself — and tells you what needs you right now.
AI triage scores every inbound message and surfaces what matters. A Priority smart view floats the important mail up, every message is tagged by category — Finance, Legal, Meeting, Security and more — and a Follow-up view gathers the replies you owe and the mail you are still waiting on. Back from lunch? One tap on "Catch me up" and Plantel Mail tells you in a sentence what the inbox needs, then lists your top priorities, the replies you might owe, and who you are waiting to hear back from — each with a one-click nudge.
- Smart views: Priority · Unread · Attachments · Follow-up, each with a live count
- Per-row priority and auto-category chips, with the numeric score on hover
- "Catch me up" digest: one-sentence summary + top priorities + replies you owe
- Auto-categorize and priority inbox toggle independently

Live product Read tracking
Know the moment it lands and gets read — with a rank rule that stops you spying up.
On mail you send, an eye icon shows Sent → Delivered → Opened (how many times, and when), with per-recipient dwell time, device, location, link clicks and even internal forwards. Five signal classes are weighted from gold to noise so the read count is real: an in-app verified read counts full, a privacy-proxy or datacenter-bot open counts zero and is filtered out. Every message gets a 0–100 engagement score and a best-time-to-follow-up hour derived from actual opens. And it fails closed on hierarchy: a built-in rank rule resolves every recipient to an org tier and only lets you track recipients you outrank — your CEO can track an employee, an employee can never track the CEO, and peers with no manager chain are blocked. It works both ways, too: Plantel Mail warns you when a sender is tracking you, and holds remote images until you ask, so spy pixels stay dark.
- Sent → Delivered → Opened with dwell, device, location, clicks and forwards
- 0–100 engagement score; bots and privacy-proxy opens filtered out of the count
- Rank rule fails closed — you can only track recipients you outrank
- Incoming-tracker detection + click-to-load images keep you invisible

Live product Smart compose
Draft, rewrite, translate, shorten and fix — right in the compose bar.
Write it once, then let the compose bar polish it. Draft a full body from a one-line instruction ("politely declines but offers next quarter") and it writes the whole message, reply-aware. Retune the tone across five settings, translate to eight languages, tighten a long message while keeping every point and the ask, or clean up grammar and clarity without changing your meaning. Every tool has a local fallback so it keeps working even offline, and you can set a default rewrite tone and default translate language.
- Draft from an instruction · Rewrite · Translate · Shorten · Fix
- 5 tones: Formal, Friendly, Concise, Assertive, Warm
- 8 languages: Spanish, French, German, Portuguese, Italian, Dutch, Japanese, Chinese
- Reply-aware drafting with an offline local fallback

Live product Humans and agents
A real address for every person — and every agent that sends on its own.
Every human and every agent gets a real, deliverable mailbox on your own domain. Agents do not just receive: they send and reply autonomously through the exact same backend send and reply routes your people use, so an outreach or support agent can run a real email thread end to end — DKIM-signed, on your domain, inheriting your sending reputation. Mailboxes are managed per domain with display names, quotas (5 GB by default, with a usage bar), owner type, a per-day send cap, and suspend or delete. And you can share an inbox the right way: grant a teammate view-only eyes or full send rights, with a hard stop so no one ever sends from a box they can only view.
- Real mailbox for every human and every agent — same signed, on-domain delivery
- Agents send and reply autonomously via the same backend routes as people
- Per-mailbox quota, display name, owner type and per-day send cap
- Delegated mailboxes with VIEW vs ACT access and a hard send-guard

Live product Power pack
Templates, rules, forwarding and a vacation responder — with guardrails.
Teach your inbox to file, flag, forward and reply on its own. Rules match on From, To, Subject or Body and act — label, star, mark read, move to a folder, auto-forward, or auto-reply — with loop guards that skip auto-replies, out-of-office and no-reply senders, a per-pass send cap, and an enable-watermark so a new rule only ever touches mail that arrived after you switched it on. Set up user-controlled auto-forwarding (everything, or only mail matching a pattern), a date-ranged out-of-office that answers once per sender per day, and reusable templates with {{first_name}} merge variables — or have AI write the template from a single sentence.
- Rules → label · star · mark read · move · forward · auto-reply
- Loop guards, per-pass send cap, and enable-watermark so automation never runs away
- Auto-forwarding (all or pattern) + date-ranged vacation responder
- Templates with merge variables, plus an AI "write this template" button

Live product Signatures
On-brand signatures your admin designs once — and everyone sends perfectly.
A real signature studio with seven designed styles, managed centrally by your admin so company branding never drifts: end users simply pick which assigned signature signs each of their mailboxes (or none) — they never hand-edit HTML. Every signature is built from the sender's actual identity — name, title, phone, website and social links pulled live from the unified profile — and assigned to everyone, to specific departments, or to specific people, with a per-mailbox choice. Rendered as bulletproof table-based email HTML with a plain-text fallback, so it looks identical in Gmail, Outlook and Apple Mail.
- 7 styles: Executive, Card, Banner, Grid, Monospace, Bold, Sleek
- Admin-managed: designed and assigned centrally, chosen per mailbox by each user
- Built from real identity — name, title, phone, website, LinkedIn, Instagram, X
- Bulletproof table-based HTML + plain-text fallback — identical in Gmail, Outlook, Apple Mail

Live product Security + DLP
A card number or API key never leaves the building by accident.
Outbound mail is scanned for the things you cannot un-send — US SSNs, Luhn-valid credit-card numbers, API keys and private keys, plaintext passwords and bank routing or account numbers. High-severity data headed to an external recipient is a hard block with a clear reason; anything sensitive auto-escalates the message to at least Confidential. A one-click classification chip labels every message Public, Internal, Confidential or Restricted, and the choice is recorded in the audit log with TLS status. Inbound is protected too: a banner the moment a message comes from outside, phishing links scanned and safely rewritten, sketchy attachments detonated in a sandbox, and a blocklist of addresses and whole domains. A per-mailbox daily send cap is a real abuse brake that actually blocks sending when reached.
- DLP scan blocks SSNs, cards, API keys, passwords and bank numbers going external
- Public / Internal / Confidential / Restricted classification, logged on send
- Inbound: external banner · link safe-rewrite · attachment sandbox · blocklist
- Per-mailbox daily send cap that actually stops the send

Live product Email becomes work
One click turns a message into a task, an event, a contact — or company memory.
Email is where work starts, not where it dies. Any message can become a calendar event (date and time parsed for you), a task, a contact, a Drive file from its attachments, a Huddle you join via a code pulled from the body, or a post to a team chat — and "Add all" runs the safe automations at once, never auto-joining a call or posting to chat for you. It can also be ingested into your Knowledge Brain as a searchable, auto-tagged, company-visible node, so what is in one inbox becomes searchable knowledge for everyone allowed to see it.
- Add to Calendar · Create Task · Add Contact · Save to Drive · Join Huddle · Share to Chat
- "Add all" runs only the safe automations, with undo on the calendar event
- Ingest to the Knowledge Brain — auto-tagged by category, Need-to-Know aware

Live product Deliverability
Auth-graded, scored, and signed at the server.
Every domain is auth-graded across SPF, DKIM, DMARC, MTA-STS, DANE and BIMI — each with a pass / pending / not-applicable badge — and every outbound message is DKIM-signed by the mail server itself, so every agent inherits your sending reputation. A live analytics tab computes an estimated inbox-placement rate (70–99.5%, derived from your real auth posture) and a domain auth score, alongside per-mailbox activity, verified domains, storage usage and your top inbound senders. Bring your own domain: add it, copy the generated MX, SPF, DKIM and DMARC records (or the whole zone file at once), press Verify, and email switches on for your whole company — with unlimited mailboxes per verified domain.
- SPF · DKIM · DMARC · MTA-STS · DANE · BIMI grading, server-side DKIM signing
- Estimated deliverability 70–99.5% from real auth posture + a domain auth score
- DNS setup wizard with copy-per-record and full-zone-file export, then Verify
- Live per-mailbox analytics and a top-senders chart from your actual mail

Live product Concrete, ownable, and built for privacy.
Real limits and real settings — not vague promises.
Eight folders + snooze
Inbox, Starred, Snoozed, Sent, Drafts, Spam, Archive and Trash — with star, snooze, label, archive and trash actions and live unread counts, kept in sync with the server.
Scheduled send
Send later at AI-suggested optimal times — each with a "why" — so your mail lands when the recipient will actually read it. Drafts auto-save and re-open into compose.
Audit log + legal hold
Every mail, security and admin action is recorded with actor, event, detail and severity, filterable and exportable to CSV or JSON for eDiscovery and SOC 2 — with retention and legal hold.
CAN-SPAM, done right
Sending to an unsubscribed address is blocked at compose, and the unsubscribe footer is enforced only on explicit marketing sends — your one-to-one mail never gets a footer slapped on it.
Any size attachment
Any file type attaches — drag-drop or paste it in, with a live upload progress bar. Up to 25 MB per message travels as true MIME attachments; anything bigger automatically becomes a secure, expiring download link in the same email, so even multi-gigabyte files just send. Bodies and attachments live in your own object storage, not a third-party silo.
Click-to-load external images
Remote images are held until you ask for them, so tracking pixels and spy-pixels do not phone home the instant you open a message.
Transport security
Configurable minimum and preferred TLS, enforce-TLS for known providers, and MTA-STS mode — plus TOTP two-factor, sessions pinned to device and IP, and suspicious-login detection.
Search across the mailbox
A real server-side search route queries the mail store directly, so finding an old thread does not depend on what your client happened to cache.
Follow-up tracking
Send a question and Plantel Mail remembers — if no reply comes back in a few days, it surfaces a "you haven't heard back" ribbon and drafts a polite nudge for you to send.
Move, flag, and sync
Real move, flag and sync routes keep folders, read state and stars consistent between the mail server and your inbox view — one source of truth.
Auto Brain ingest
Every email can be extracted into your Knowledge Brain, so its contents become searchable company knowledge — auto-tagged and Need-to-Know aware — instead of staying buried in one inbox.
An inbox your whole workforce shares.
Real addresses for every human and agent, AI insights, read tracking and inbox-grade deliverability — included in every seat.
