Every white-label product has a seam somewhere. The useful question isn't whether one exists — it always does — but where it is, who's likely to find it, and whether that matters for the customers you're selling to.
White label email means your clients sign in at your domain, see your logo, and get password-reset messages from your brand. Underneath it's the same platform, and there are a few places where that shows through. This is an honest account of both halves: what's genuinely yours, what stays ours, and which of those a technical customer might notice.
Who White Label Email Is Actually For
White label email earns its keep in three situations.
An agency bundling email into a managed offer. You already handle the client's domain, DNS and website. Email arriving as a visibly third-party product undercuts the impression that you run their infrastructure, and it hands them a vendor name to go and price-check.
A SaaS or reseller packaging email with something else. A "powered by" line in your customer's inbox is a competitor's brand in your customer's daily workflow.
An established brand that doesn't want a stranger's logo in its own password-reset mail. Nothing to do with reselling; it's about a consistent internal experience — the same reason you would set a domain signature rather than ask fifty people to paste one.
If you're a small team that doesn't care about surface branding, skip it. The underlying product is identical, and white label email changes nothing functional.
What White Label Email Puts Your Brand On
These surfaces are fully yours, with your name, logo and colours:
- The login screen, at your own host such as
dashboard.yourbrand.com. - The dashboard — sidebar, page titles, navigation, primary and accent colours.
- Webmail, where your customers spend their actual working day.
- Transactional email — password resets, mailbox invitations, account notices. The visible From name and the message body are yours, and if you set a support address those messages carry a Reply-To pointing at you rather than bouncing off a no-reply.
- The SSL certificate, issued in your domain's name.
- The browser tab title.
You can also point a help-centre URL at your own knowledge base, and every branded message picks up a "Need help?" link to it. That one matters more than it sounds: support links are where a white label email setup most often leaks, because they're easy to forget.
Where White Label Email Shows Its Seams
This is the section other vendors leave out, so here it is plainly.
Mail server hostnames. A customer configuring Outlook by hand enters IMAP and SMTP hostnames, and those belong to the underlying platform. Most customers never see them, because setup guides and configuration profiles fill them in. A customer who reads what they're pasting will notice.
Message headers. Every email carries Received headers describing the servers it passed through, as the SMTP specification requires. Anyone who opens "show original" can read the infrastructure's name. No white label email product can hide that, because forging those headers would break the authentication that gets your mail delivered.
DNS records. The MX, SPF and DKIM records on your client's domain point at the platform. They're public by design — that's what DNS is — and anyone can look them up.
Billing and support escalation. One commercial relationship per account, which is what makes this the "Lite" tier. You can brand as many domains as you like underneath it, but invoicing runs through us. If you need separate billing entities each with their own invoicing, that's a different conversation.
The practical read: for a small-business client who wants working email, the branding is complete. For a technically curious customer who inspects headers, it isn't, and it can't be. Price and pitch accordingly — and if a client asks directly, "we run it on infrastructure we manage for you" is both true and sufficient.
How White Label Email Hosts Work
Each branded host is a CNAME on your domain pointing at the platform. You create the record, we issue the certificate, and the host serves your branding.
Typically that means dashboard.yourbrand.com for the control panel and mail.yourbrand.com for webmail. Both are verified before they go live, so a mistyped CNAME fails at setup rather than presenting a certificate error to a customer.
Two things worth planning. Pick the hostnames once — changing them later means every customer's bookmark breaks, and bookmarks are how people actually reach webmail. And keep them on a domain you're keeping; branded hosts on a domain you let lapse is a bad afternoon for everyone.
DNS for a client's mail domain is separate from this and is the larger job when you're onboarding a portfolio. Doing it by hand is where errors creep in, so it's worth reading automatic DNS setup before onboarding a dozen domains.
White Label Email Is Per-Domain, Not Per-Account
White label email is configured per domain rather than once per account, which is the design decision that makes it useful for an agency.
You can run one brand for clients under a managed offer and a different one — or none — for domains you operate directly. A reseller with two brands can serve both from one account. And onboarding a client who wants their own branding rather than yours is the same operation with different assets.
Verification is per host too, so adding a domain doesn't disturb the ones already live.
The Economics of Reselling White Label Email
The add-on is a flat monthly fee, the same regardless of which mail plan you're on, and it's available on every plan. Current pricing is on the White Label page rather than quoted here, because prices change and a blog post is a bad place to learn that.
What matters more than the fee is the shape of the underlying product. Mail plans are flat-rate rather than per-seat, so a client with forty mailboxes costs you the same as a client with four. Your margin comes from the gap between a flat cost and whatever per-user price your market expects — and that gap widens with every mailbox the client adds, which is the opposite of how reselling a per-seat product works.
The Drive storage add-on also carries a discount while white label email is active, applied when you buy or resize. Keep it as margin or pass it on.
One operational note: because there's one billing relationship, you're the support desk. That's usually what you want — it's the point of the branding — but staff for it. Clients will email you about mail apps not connecting, and having read how the product actually behaves beats forwarding every question upstream.
Configuring White Label Email Over the API
White label email is part of the API surface: set a domain's identity, upload logos, read back the CNAME records to create, and trigger DNS verification, all programmatically. The same tools are available to an agent over MCP.
For an agency onboarding clients regularly this is the difference between a repeatable script and a checklist somebody works through by hand at 6pm. The whole sequence — add domain, apply DNS, create mailboxes, configure branding, verify — is automatable end to end.
Frequently Asked Questions
Will my customers see the underlying provider?
Not in normal use. The dashboard, webmail, login screen and transactional mail all carry your brand. A customer who inspects message headers, looks up DNS records, or reads mail-server hostnames while configuring a desktop client can find it — no white label email product can prevent that without breaking mail authentication.
Do I get my own SSL certificate?
Yes, issued in your domain's name for each branded host. You create a CNAME, the certificate is issued automatically.
Can white label email cover more than one domain?
Yes. White label email is per domain, so one account can serve several brands with different logos and colours.
Does white label email change how mail is delivered?
No. It changes the interface and the transactional messages. Delivery, filtering and authentication are identical.
Can I invoice my customers separately?
Not through the platform. There's one billing relationship per account, which is what makes this the Lite tier — you bill your customers yourself, however you already do.
Which plans include white label email?
It's an add-on available on every plan, at the same price regardless of which mail plan you're on.
What happens if I cancel?
The branded hosts stop serving your brand and customers land on the standard interface. Nothing about their mailboxes or mail changes, but their bookmarks will look different, so tell them first.
Can I set white label email up through the API?
Yes — identity, logos, branded hosts, the CNAMEs to create and DNS verification are all available over the REST API and MCP.
