Running a White Label Cold Email Provider Under Your Own Brand

Who Owns the Domain and the Sender Name

Every client needs its own sending domain, and the registration should sit with the client or with your agency, never with the provider. If the client leaves, the domain leaves with them and their history stays intact. Set the sender name to a real person at the client company, because replies routed to a generic agency inbox get ignored.

The white label layer covers what the recipient sees. Tracking domains, signature blocks and the reply-to address all point at the client, not at this platform. Your agency name appears on the invoice and nowhere in the message. Decide this before the first campaign, because changing a sending domain later resets the reputation you have built on it.

Keep a written list of which domains your agency controls and which the client holds. This matters at offboarding and at any dispute over the mailbox data.

• Register each client domain in the client's name or your agency's, never the provider's
• Point tracking and reply-to records at the client domain
• Record the sender name as a named person at the client company
• Store credentials for every domain in one agency-owned vault
• Confirm in writing who keeps the domain if the engagement ends

If you would rather not run the sending layer yourself, look at amanaged cold email service for agenciesand compare it with the white label route before you commit.

Separating Billing From the Client Invoice

Your clients should never see a line item from this platform. You buy the sending plan, and you invoice the client for the service you deliver. That means one plan per volume band you resell, or a pooled plan you divide across accounts. Growth at $38/month covers 10,000 emails a month and includes a reply inbox, which is enough for several small client campaigns.

Work the numbers before you quote a client. Three small accounts sharing Growth at $38/month is one charge to you; if each client needs its own login and reply inbox, buy three plans instead and price each engagement to cover a single plan. Scale at $78/month raises the ceiling to 50,000 emails and adds mailbox health reporting.

Billing separation also means the client never receives a password reset or a renewal notice from a brand they do not recognize.

• Invoice clients under your agency name only
• Match each resold plan to one volume band you can forecast
• Keep platform renewal notices on an agency-owned billing address
• Charge per engagement, not per message, so overage stays your risk
• Review plan size each quarter against actual send volume

Agencies that prefer to own the sending stack outright canbuy cold email softwareand run it on their own domains instead of reselling a plan.

Where Your Support Stops and the Provider Starts

The support boundary is the part agencies get wrong. Your client calls you when replies dry up or a domain lands in spam. You call the provider when SMTP credentials fail or a mailbox shows a health warning. Write that split into the client contract in plain terms, so nobody escalates a copy question to infrastructure support.

In practice the agency owns strategy, copy, list quality and client communication. The provider owns delivery infrastructure, warm-up and mailbox diagnostics. Business at $198/month adds diagnostics and two SMTP slots, which helps when you need to show a client why a campaign paused.

Set a response time you can actually meet before you promise one to a client, and pass provider response times through honestly rather than absorbing them silently.

• Publish the escalation path in the client agreement
• Agency handles copy, targeting, reporting and client calls
• Provider handles SMTP faults, warm-up and mailbox health
• Log every infrastructure ticket with a timestamp
• Tell clients when a delay is infrastructure rather than strategy

Matching Plan Size to Client Volume

Pool volumes only when clients share a sender identity. If two clients send from separate domains, their reputation is separate and their plans should be too. Agency at $498/month covers 250,000 emails, five SMTP slots and API workflows, which suits a roster of mid-sized accounts run from one dashboard.

Enterprise at $1000/month raises that to 500,000 emails, ten SMTP slots and a managed pool. The managed pool is the one place where shared infrastructure is the point, and it is worth reading the terms before you put a client on it. Starter at $18/month is a sensible trial plan for a single new account you are testing.

Do not sell a client more volume than their list can support. A 2,000-contact list sent four times a month is 8,000 emails, which fits Growth at $38/month with room for follow-ups.

• Keep separate plans for clients with separate sender domains
• Use one pooled plan only where the contract allows shared infrastructure
• Start new accounts on Starter at $18/month until the list is proven
• Size follow-up sequences into the monthly volume, not just the first send
• Move a client up a band when sustained volume approaches the ceiling

What the Client Sees and What They Do Not

The client sees your logo, your reporting format and your account manager. They do not see the sending platform, its pricing or its documentation. That means your reports must translate infrastructure signals into plain language: a paused mailbox becomes a note that sending is on hold while the domain recovers.

Build one reporting template and reuse it across accounts. Keep the same metrics every month so clients compare themselves to their own past, not to an invented benchmark. If you cannot explain a dip in replies, say so and say what you are testing next.

White label does not mean hiding problems. A client who learns about a deliverability pause from a third party will not renew.

• Use an agency-branded report template for every client
• Translate infrastructure warnings into plain sentences
• Report the same metrics each month for comparability
• Disclose pauses before the client notices a drop
• Keep platform documentation out of client-facing material

Monthly plans an agency can resell under its own brand, by send volume and SMTP slots

These are the provider's monthly charges to your agency, not what you invoice clients; lifetime deals sold elsewhere are separate, and code SALE20 takes 15% off those lifetime purchases.
