White-label email hosting.
Your brand, your domain.
Resell business email under your own name. The dashboard, the webmail, the mail apps and every system email carry your brand on your own domain. Flat $39 a month. Nothing per mailbox, nothing per person, no partner programme. Thirty days free.
Card required · cancel before day 30 · a card and one DNS record, no partner programme and no sales call
Custom domain · 99.99% uptime · Move existing clients in with zero downtime
Built for teams who ship email at scale, under their own brand.
Your brand on
every surface.
Domain, logo, colors, sending and every page, branded per domain or account-wide. White Label rebrands the whole product; TrekMail disappears from your customer's view.
Point a CNAME.
Your domain everywhere.
Pick any subdomain on a domain you own: app., mail., portal., my. Host the whole product on one host, or split it: Dashboard on one, Webmail on another. SSL provisioned and renewed automatically.
Each domain,
its own sender.
Route every client domain through its own SMTP: the TrekMail relay, or its own Postmark, SES, Resend or Mailgun. One client's reputation never touches another's.
Your logo and colors.
Upload a light-theme logo, a dark-theme logo and a favicon. Pick one brand color, and we auto-derive light & dark variants for buttons, links, focus rings and charts.
Every page, your brand.
Sign-in, two-factor and password reset all carry your logo, your color and your domain. TrekMail never appears.
One brand, or one per domain.
Brand the whole account at once, or give each domain its own logo, colors, sender and name. Set it in the dashboard, or in one API call.
Drive storage:
10% off current prices.
Pooled file storage backs email attachments, customer uploads, file workspaces and automated backups. 200 GB is included on Agency, expandable to 100 TB. White Label tenants get 10% off current Drive prices when buying or resizing.
Every system email, your name.
Replies go straight to your support inbox, not ours. Every system email (welcome, 2FA, billing, password reset, deliverability digests) ships from your domain with your custom “From” name.
Brand the From line.
Route the replies.
Your From name, your address, and a support link inside every system email. Customers see your brand and reach you when they need help.
- Welcome · password reset · 2FA · deliverability digest · invoice notifications
- Your support URL or address appears inside the body, so customers contact you, not us
- TrekMail name never appears in the From, headers or footer

- 1 Invite by email They land on your branded sign-in, not ours.

- 3 Assign their domains They see those and nothing else. Change it any time.
Cannot reach
They never see
our name.
When your customer sets up email on their phone, the server name they type is yours.
Three records on your domain switch it on. We handle the certificate.
Email hosting for agencies,
MSPs and resellers.
Same product, four go-to-markets. Pick the model that fits, or run more than one.
Email under your brand, alongside your retainer.
Resell email as a managed service. One workspace, up to 1,000 client domains, managed from a single console.
Email as a managed product, not a vendor reseller.
Per-domain SMTP routing: each client domain via its own relay or IP (TrekMail, or BYO Postmark / SES / Resend / Mailgun). SPF, DKIM, DMARC and MTA-STS published per domain.

Embed mailboxes, drive and webmail into your app via the REST API and 245 MCP tools. Your customers never see TrekMail, only you.
Internal mail product, branded for the company.
Run mail for a large org under the internal brand, with up to 1,000 domains per workspace, with the full deliverability stack.
The email infrastructure
behind your brand.

They bill per mailbox.
We don’t.
$39 a month for White Label however far you grow, and the mail plan underneath moves itself, starting from the free one.
At this size per-mailbox billing is cheaper, and it bundles more storage each. Drag further to see where that turns around.
Compared at $3 a mailbox, the top of a published range that starts at $0.50.
Per-mailbox providers bundle 15–25 GB each. This compares the price of the platform, not the disk. Add pooled Drive and White Label takes 10% off it.
