Platform overview

A complete email marketing business. Yours, on one login.

A branded portal for every client. A design-first campaign builder with AI. A sending engine that solves deliverability before you press send. Reporting clients believe. Billing in your name. This page walks the whole thing, in the order your clients experience it.

Five pillars

Everything you will bill for, and everything that makes it deliverable.

Sending infrastructure

Brand-matched domains registered, authenticated and hosted for every client. Warmup that runs itself. Every campaign balanced across every domain and paced to what each receiver rewards. This is why the mail lands.

AI production

A designed HTML email from the brand and campaign presets, in the client’s brand. A matching landing page on the client’s own domain. A pre-send review that reads like a specialist wrote it. Production time becomes margin.

White-label portal

Your domain, your logo, your welcome email, your billing. Clients log in to your platform.

Audience data

Mailbox-level verification with reasons a client understands. Segments that snapshot at launch. Forms with double opt-in.

Reporting

Human opens separated from scanners. Per-domain, per-variation, shareable by link under your brand.

How it fits together

Start with the domains. Everything else stands on them.

Every client account begins with sending domains — variations of the client’s own name that the platform registers, authenticates and hosts. The client never sees a DNS record. Those domains carry the client’s mail, serve its tracking links and host its landing pages. One brand, one set of domains, everything aligned: that is the foundation of the deliverability the platform is known for.

New domains warm themselves. Volume starts small and grows as receivers accept the mail; a domain that draws bounces is slowed, never pushed. When a campaign launches it is spread across every domain the client has and paced separately for every receiver, so nothing arrives as a burst.

Before a message is allowed into a campaign, the address it is going to has been verified with the receiving server. Lists carry their own history: what was removed, why, and what was suppressed platform-wide. Segments turn engagement into rules, and those rules become a fixed audience the moment a campaign launches.

On top of all of that sits the part your clients actually see: a campaign builder that begins with the creative. A brand preset and a brief go in; a designed email, its variations, a matching landing page and a pre-send review come out. Then a report — human opens only — that you share by link.

And all of it wears your brand. Your portal domain, your logo, your welcome emails, your team, your billing. We built the platform; you get to be the one who owns it.

A client’s first week

From “can we move our email to you?” to a report in their inbox.

1

Create the client account

Name, brand preset, logo and colours. The platform seeds a sample workspace so the client sees a working campaign before they have sent one.

2

Let the domains come online

The platform proposes brand-matched names, registers them, sets up authentication and starts warmup. Nobody touches DNS.

3

Import and verify the lists

The importer maps their spreadsheet, resumes if interrupted and verifies every address at the mailbox. Removal reasons are shown in plain language.

4

Build the first campaign

Brief in, designed email out. Add the landing page, pick the engaged segment, schedule. The pre-send review flags anything worth fixing.

5

Send the report

Delivered, human opens, clicks, bookings — under your brand, by share link. This is the conversation that turns a trial into a retainer.

The business model

One overhead. Unlimited clients. Your prices. Billed in your name.

A handful of the clients you already have covers the platform. Everything after that is margin — and it arrives on the first of the month.

FAQ

Platform questions

Is this a template catalogue or a sending platform?

A sending platform, with a design studio on top. The core of SendTo is the engine that registers and warms domains, verifies lists, balances and paces delivery, and reports honestly. The AI design tools exist because campaigns need to be produced — and produced beautifully.

How much do I have to configure?

Very little. Domains, authentication, warmup, pacing and suppression are automatic. Your configuration is your brand, your clients and your campaigns.

Can my team work across all of my clients?

Yes. Invite team members with a role and they work inside any client account. View-as access lets you help a client without asking for a password.

Does it suit one big client as well as many small ones?

Yes. Load balancing, pacing and warmup scale with volume, and additional managed domains can be added to any client account.

What do I bring?

Your brand and your clients. The platform supplies everything else, including the domains.

See the whole platform under your own brand.

Create your account, open the sample workspace and walk a real campaign end to end. No card needed to look around.
