We review your sending volume, contact base, and dispatch frequency, then agree a guaranteed open-rate target to be met within 90 days. Your private email server is designed and provisioned to that specification within 48 hours.
Your infrastructure is vertically integrated end to end: private hosting, dedicated data storage, the dispatch system, dedicated IPs, full authentication (SPF, DKIM, and DMARC), and built-in list validation. At no stage are you required to touch a configuration file.
Your list is imported, then cleaned and validated in full. Sending opens on a staged warming schedule of 5 on day one, then 10, 20, and 40 as reputation accrues, while your domain is engaged with established, high-reputation inboxes to accelerate placement. An opt-in system is configured so every new contact enters compliant.
On completion, the credentials to every account and system are transferred to you. The server, the IPs, and the data are held in your name and owned outright, leaving no provider account that a third party can withdraw.
A few questions, then pick a time. No pressure.
Double the ~20% industry-average open rate at full production volume.
Mainstream providers can suspend a legitimate sender overnight for its industry or jurisdiction. A private, dedicated server removes that single point of failure.
Your lists and your customers data live only on your server and never touch ours, so there’s nothing on our end to hold, sell, or share. Data sovereignty is the whole point.
Bulk validation is built in, so you protect your sender reputation instead of burning it. Inbox placement comes down to two things: solid infrastructure and a clean list, and you get both.
A private server removes your provider’s ability to shut you down. It does not override mailbox-provider spam filtering or public blocklists, which is exactly why list hygiene and validation are built into the service.
Nothing drops on your current setup. It keeps running exactly as it is while we build and warm the new infrastructure alongside it. Proper warmup is gradual and takes as long as it needs; we only move you over once a live inbox-placement test proves the new infra lands, so you’re never rushed onto a cold, unproven IP.
Completely. Your lists and your customers’ data live on your own server and never touch ours, so there’s nothing on our end to hold, sell, or share. If you ever leave, you keep the server, the IPs, and everything on them.
That’s exactly who we’re built for. Mainstream ESPs suspend legitimate senders over industry, volume, or jurisdiction. A private, dedicated server removes that single point of failure. There’s no shared platform account for anyone to switch off. We’ll review your history on the call and design around it.
Tomorrow, in many cases. We start provisioning and warming the moment your fit call wraps, and we’ll lock a firm go-live date with you on that call based on your volume.
Your infrastructure is set up and run by people who do email infrastructure for a living: provisioning, authentication, IP warmup, list validation, and ongoing monitoring. Once it’s live it runs on its own, and our team is there whenever you need us. We agree the exact support and uptime terms with you in writing before you start.
Before you commit to going live, we run a live seed-placement test and show you your infrastructure landing in the inbox. You only move forward once it’s proven, so you’re never paying for an unproven setup, and we’re never asking you to take placement on faith. Built-in list validation keeps your own list quality from quietly dragging placement down.
Postelist is a done-for-you build plus an ongoing managed service, priced to your volume and scope. We confirm exact pricing on a short, no-obligation fit call before anything begins.
