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

White-label is included from 50 paid mailboxes and costs $50 a month below that, with no setup fee. Clients sign in on your own hostname and see your product name and favicon, with your logo on the help center pages. Our team sets up the certificates.

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.

With white-label, your clients use the control panel on your own hostname, under your product name, while Atriomail runs the platform behind it. It is included for accounts paying for 50 or more mailboxes, and $50 a month below that, with no setup fee. One white-label covers every hostname you brand. Set your own prices and keep the margin.

  • Your own mail server hostname (e.g. mail.yourcompany.com)
  • Your product name and favicon in the panel, your logo on the help center
  • Your clients can use our live chat on your hostname too: on by default, or switched off by you
  • Certificates for your branded hostnames, set up by our team

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. You set your own prices, and mailboxes use standard IMAP, so mail can be copied to another provider before you cancel. No cancellation fee.

✓ Proof: IMAP migration has no charge and is built into the panel.
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

Live chat, then the people who build it

Live chat sits inside the control panel and comes with every account. An AI assistant answers first, and people take over during business hours: the small team that builds the product.

✓ Proof: with a one-time support code the assistant can look at your account, and every change waits for your yes.
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.
