Tell us your volume and list size. We design your private email server around exactly that, live within 48 hours.
Hosting, dedicated IPs, authentication, list validation: every piece built and connected for you. You never touch a config file.
We import and clean your list free, then ramp sending up gradually so inboxes learn to trust your domain before you scale.
Server, IPs, and data end up in your name, owned outright. No provider account a third party can ever switch off.
Just your name and email to start — takes about 90 seconds. No obligation.
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.
Tell us about your business and we’ll let you know if private email infrastructure is the right move, and exactly what it would look like for you. Your mail lands, or the build’s on us.
