Why Atriomail

Everything you need to sell email under your own brand.

Built for resellers, agencies and hosts who want a profitable, fully-automated email product, without building the infrastructure themselves.

Your brand, front and center

Full white-label branding, your domain, your logo (light & dark), your colors and a custom login. Clients see your brand, never ours, with automatic SSL.

Built to land in the inbox

SPF, DKIM and DMARC are generated and published for every domain automatically, on enterprise-grade sending infrastructure, so your clients' mail is trusted and delivered.

Live in minutes

Add a domain and Atriomail configures DNS automatically across 15 DNS providers and 4 major control panels (cPanel, Plesk, DirectAdmin, ISPConfig). No cryptic records to copy.

Migrate clients painlessly

Built-in IMAPSync moves mailboxes from Gmail, Microsoft 365, Yahoo or any IMAP server, folders and dates preserved, with real-time progress. Migration is always free.

Automate everything

A full REST API with OpenAPI docs, plus ready-made WHMCS, Blesta and n8n integrations, lets you provision domains, mailboxes and forwarders automatically end to end.

Pricing you profit from

One simple wholesale price of $1.39 per mailbox that you mark up and pass through to clients. Unlimited domains, aliases and forwarders included. No setup fees.

White-label

Your brand. Not ours.

Atriomail runs quietly in the background while your clients see only you. Brand the webmail, the login page, the domains and the messages, then set your own prices and keep the margin.

  • Custom webmail domain (e.g. mail.yourcompany.com)
  • Your logo in light & dark mode, colors and favicon
  • Custom login page, clients never see Atriomail
  • Automatic Let's Encrypt SSL on every branded domain

Deliverability

Mail your clients can rely on.

Email only works if it arrives. Atriomail authenticates every domain correctly from day one and sends on enterprise-grade infrastructure, so messages reach the inbox instead of the spam folder.

  • SPF, DKIM and DMARC generated and published automatically
  • Enterprise-grade sending infrastructure
  • Autodiscover & autoconfig for Outlook, Thunderbird & Apple Mail
  • SSL/TLS encryption, spam filtering and antivirus included

Automatic DNS

Connect a domain. We handle the records.

DNS is where most email setups break. Atriomail detects your provider and publishes every record automatically, MX, SPF, DKIM, DMARC, autodiscover and autoconfig, across 15 DNS hosts and the major control panels.

How it works

From sign-up to selling email in three steps.

  1. 1

    Create your account and add domains

    The account is free and needs no card; mailboxes are billed from the first one. If the domain's DNS is on Cloudflare or Namecheap, connect that account before you add the domain. Once the domain passes the security check, Atriomail can write its MX and DKIM records, plus SPF and DMARC where none exist; writing MX moves the domain's mail, so add a live domain only when you are ready to switch. On any other DNS host, the DNS Setup dialog lists each record with a copy button.

  2. 2

    Create mailboxes and bring existing mail over

    Each mailbox includes 15 GB. Copy existing mail into your new mailboxes from any server that allows password sign-in over IMAP, then add aliases, forwarders and a catch-all on any domain that has a mailbox.

  3. 3

    Set your price and sell

    You pay $1.39 per mailbox per month and charge your clients whatever you choose. Provision your clients' mailboxes from the control panel, the REST API or the module for WHMCS 9.

What we stand for

Four promises we build the product around.

Email is infrastructure, you're trusting us with the channel your business runs on. That trust is earned with principles you can verify, not slogans.

01

Radical price transparency

One public price: $1.39 per mailbox, $0.60 per extra 5 GB. Your invoice is itemized line by line, and the free things (domains, aliases, forwarders) are printed on it as free, forever.

✓ Proof: open the Billing tab above, the screenshot is the real billing page.
02

You own your business

Your brand, your clients, your margin. We stay invisible behind your white-label, and if you ever want to leave, IMAP migration works in both directions. No lock-in, no exit fees.

✓ Proof: migration tooling is free and built into the panel, in and out.
03

Boring reliability

Email should just work. Every domain is authenticated from day one, mail is encrypted in transit, spam and viruses are filtered, and two-factor authentication protects every account.

✓ Proof: SPF, DKIM and DMARC are published automatically, check any domain you add.
04

Humans, not ticket queues

Live chat sits inside the panel and real people answer it, the same people who build the product. Migrations come with hands-on help, included in the price.

✓ Proof: the chat bubble in the screenshots isn't a prop, say hello.
Pricing

One simple price. No tiers, no surprises.

Pay only for the mailboxes you use, billed monthly. Mark it up and pass it through to your clients, the margin is yours.

FAQ

Questions, answered.

What is Atriomail?

Atriomail is a white-label email hosting platform for resellers and agencies. It provides professional, custom-domain email with automatic DNS management, full white-label branding, control-panel and DNS-provider integrations, and a REST API, so you can sell email as your own product.

How much does it cost?

$1.39 per mailbox per month, with 15 GB included. Need more space? Add storage in 5 GB blocks at $0.60 each per month, with no upper limit. Domains, aliases and forwarders are free and unlimited, and there are no setup fees.

Can I sell email under my own brand?

Yes, that's the whole idea. White-label branding gives you a custom webmail domain, your logo in light and dark mode, your colors, a custom login page and automatic SSL. Your clients see your brand, never Atriomail. White-label is available as an add-on; contact sales to set it up.

How does email migration work?

Built-in IMAPSync moves mailboxes from Gmail, Microsoft 365, Yahoo or any IMAP server. It preserves your folder structure and message dates and shows real-time progress. Migration is included at no extra cost.

Which DNS providers and control panels are supported?

Atriomail automatically manages DNS across 15 DNS providers, including Cloudflare, AWS Route 53, GoDaddy, Namecheap, DigitalOcean, Azure DNS and more, plus the major control panels: cPanel, Plesk, DirectAdmin and ISPConfig.

How do you ensure deliverability?

Every domain is authenticated correctly from the start, SPF, DKIM and DMARC are generated and published for you, and mail is sent on enterprise-grade infrastructure with SSL/TLS encryption. The result is properly authenticated email that inbox providers trust.

Is there an API and billing integration?

Yes. A full REST API with interactive OpenAPI documentation lets you provision domains, mailboxes, forwarders and more programmatically, and ready-made WHMCS, Blesta and n8n integrations connect Atriomail to your billing and automation stack.

How does billing work?

Usage-based monthly billing with one consolidated invoice, charged via Stripe (invoicing is available for volume partners). Only administrators are billed for the mailboxes they create, the regular users they assign mailboxes to are not charged.
