Deliverability, handled

Deliverability, handled for every client. Nobody on your team has to run it.

Every input a receiving mail server weighs (the domain, its authentication, its warmup, the sending rate, the quality of the list, bounce and unsubscribe handling) is engineered into the platform, for every client, on every campaign.

Every campaign, at least four creative variants

A campaign cannot launch with fewer than four creative variants. They rotate across recipients and across the client’s sending domains, so receivers do not see a wall of identical mail from one place, and the report shows each variant on its own row.

  • Variants produced with the design, from the same brief
  • Rotated evenly across recipients and domains
  • Per-variant results, human opens only

Alignment: one brand, one domain, end to end

For every recipient, the From address, the signature, the tracking links and the landing page all belong to the one brand-matched domain that carried their message. Tracking links and landing pages are served on the sending domains themselves.

  • From, signature, links and page on one domain per recipient
  • Tracking hostnames on every sending domain
  • Landing pages served on the sending domain

Verification: prevent the bounce instead of counting it

Every address on every list is checked with its receiving mail server before a campaign is built, and the results are kept: safe to send, mailbox gone, domain dead, suppressed elsewhere, held for a deeper check. Every removal carries a reason you can repeat to a client.

  • Mailbox-level checks, not syntax checks
  • Removal reasons written for the client
  • Removed addresses kept as a record

An honest definition

We engineer every input. Receivers decide the inbox.

Delivered: engineered and measured

A message is delivered when the receiving server accepts it. That is an event the platform observes and reports per domain. Verified addresses, warmed domains, governed pacing and clean authentication are what keep it high.

Inbox placement: earned

Once accepted, each receiver decides where a message goes, using the reputation the sending domain has built with it. A new domain has no history yet, so its early mail is placed cautiously. Warmup, engaged-first segments and verified lists build that history as fast as it can safely be built.

In practice

What your team does about deliverability: nothing. That is the point.

You do not configure warmup or choose a sending rate. You do not add a tracking domain, set up a landing-page host, or send a list to a verification vendor and back. Every one of those steps exists on other platforms because the platform did not want to own the outcome.

What you do is create a client, import their list, build the campaign and launch. The platform decides which domain carries each message, how fast each receiver gets it and which addresses were safe to send to. Everything it decides is visible in the portal.

That leaves you free to sell the outcome, with the screens that show why the numbers are what they are.

FAQ

Deliverability questions

Do you promise inbox placement?

No, and you should be wary of anyone who does. Inbox placement is decided by each receiver, using the reputation a domain earns with that receiver over time. What the platform does is engineer every input those decisions are made from.

Will a brand-new client’s mail go to spam at first?

Some of it can, until the new domain has history. That is what warmup, verified lists and pacing are for. Starting with a client’s most engaged segment helps the domain earn its reputation fastest.

Do clients share domains?

No. Every client sends from their own brand-matched domains.

What happens to a domain that starts bouncing?

It is slowed automatically, the addresses that bounced are suppressed platform-wide, and the balancer shifts volume to the client’s other domains. You see it in the domain’s status.

Do I have to configure any of it?

No. Domains, authentication, warmup, pacing, verification and suppression are automatic.

Is it really for life?

Yes. Create your account with the code by 31 December 2026 (11:59 pm US Pacific) and 75% comes off the platform fee for as long as you remain a partner. At today’s list price of $3,200 a month, that is $800.

What happens when the countdown ends?

The code stops working for new accounts, and new partners pay the standard $3,200 a month. Partners who created their account with the code before the deadline keep their discount.

Do I have to activate before the deadline?

No. The discount is attached to your account when you create it. Explore for as long as you like and activate when you are ready to sell.

Someone sent me a code with their name on it. Which do I use?

Theirs. A personal code is LAUNCH75 followed by the referrer’s code, gives you exactly the same discount, and makes sure the person who introduced you is credited. If you arrived through their link, it is already filled in.
