What Atlas Mail Includes

Nine things on the per-mailbox price — your domain, no ads, no scanning, no AI training, dedicated IPs, and a real engineer on the other end of support.

Your domain ([email protected])

Custom domains on every plan with one-click DNS setup. SPF, DKIM, DMARC, BIMI — all wired automatically. No 'professional email' add-on tier required.

Zero ads in your inbox

Not now, not ever. Atlas Mail makes its money from per-mailbox subscriptions, not from selling sponsored placement next to your incoming messages.

Mail content never scanned

Spam and phishing filtering happens at the protocol layer — never on the contents of your private messages. No keyword analysis, no profile-building, no advertiser targeting.

Not used for AI training

Your mail body, attachments, and metadata are never used to train models — Atlas's, partners', or anyone else's. A clause in the contract; not a marketing line.

Dedicated sending IPs

Reserved sending IPs with Atlas-warmed reputation included on Team plans and above. Ship transactional and marketing mail without sharing a reputation pool with strangers.

Unlimited aliases

As many catch-all addresses, role aliases, and project handles as your team needs. No per-alias billing, no monthly cap on +tag forwards.

Engineer-staffed support

Real humans, 24/7 — and the on-call rotation is the same engineers who run the platform. Page us with a SMTP TLS error and an engineer answers, not a tier-routed bot.

Region-pinned data

Choose where your mailboxes physically live — US, EU, or APAC — and Atlas Mail keeps the data there. Compliance frameworks (GDPR, HIPAA BAA, SOC 2) on request.

Full IMAP / SMTP access

Standard IMAP, SMTP, and POP3 endpoints with no proprietary client lock-in. Use Apple Mail, Thunderbird, Mutt, or anything that speaks the protocols.

Migrate In Minutes. Not Months.

Our migration engine pulls your entire mail history from Gmail, Outlook, or any IMAP provider — folders, labels, filters, contacts, calendars — and lands it pristine in your new mailbox. You barely lift a finger.

Atlas · Field Notes

Frequently asked.

Real questions from buyers and integrators — straight answers.

01

What makes Atlas Mail different?

Flat per-mailbox pricing with every feature on every tier, identical IMAP/SMTP access, unlimited custom domains and aliases, dedicated warmed sending IPs, a 10/10 sender score, and a contractual line that your data never gets scanned for advertising or AI training. Calendar and contacts sync over CalDAV/CardDAV so existing clients work unchanged.

02

What spam protections does Atlas Mail include?

SPF, DKIM, and DMARC are enforced by default; transport is TLS 1.3; inbound mail passes through a multi-layer Bayesian + heuristic filter that blocks 99.98% of spam with near-zero false positives. Outbound flows through dedicated, warmed IPs to keep deliverability above 99.99%.

03

Can I use my own domain?

Yes — every plan includes unlimited custom domains and unlimited aliases per user. DNS records (MX, SPF, DKIM, DMARC) are generated for you on signup; most domains validate within minutes.

04

How does migration from Google Workspace or Microsoft 365 work?

Atlas runs the migration end-to-end at no extra cost: IMAP sync of every mailbox, calendar import, contact import, and a cutover plan that keeps mail flowing during the DNS swap. Most teams under 100 seats are fully migrated in a single business day with zero lost messages.

05

Is my mail private?

Yes. No advertising scans, no AI training on your inbox, no third-party data brokers. Atlas Mail is operated under GDPR and CCPA-compliant data-processing agreements and stored on Atlas-owned hardware in jurisdictions you choose.

06

Does Atlas Mail support catch-all and shared mailboxes?

Yes. Catch-all addresses, shared inboxes (support@, sales@, billing@), distribution lists, and per-domain forwarding rules are all included. No add-on tier required.

07

What clients can I use with Atlas Mail?

Anything that speaks IMAP/SMTP — Apple Mail, Outlook, Thunderbird, Spark, Gmail's web client (as an external account), and every major mobile client. There is also a clean first-party web client for users who prefer browser-based mail.
