Provisioning pipeline

From cut off to fully in control

  1. 01

    Assess & design

    We review your volume, sending history, and industry, then design infrastructure that fits your business, not a one-size-fits-all box.

  2. 02

    Build, done for you

    We provision your private email server end to end: dedicated IPs, full authentication (SPF, DKIM, DMARC), and built-in list validation. You never touch a config file.

  3. 03

    Migrate with zero downtime

    Your current sending keeps running while we build and warm your new infrastructure in parallel. We only cut you over once it’s proven on a live inbox-placement test, so there’s never a gap, and never a reputation hit.

  4. 04

    Own it, fully managed

    It is yours. Your data lives on your server; our team manages and monitors the infrastructure. There is no provider account anyone else can switch off.

The Postelist guarantee

Your mail lands, or you don’t pay

A done-for-you service should carry the risk, not you. So we do.

  • Proven before you go live

    We prove inbox placement before you commit, or the build’s on us.

  • Zero-downtime migration

    Your current sending keeps running until the new setup is proven.

  • No lock-in, ever

    Your server, your IPs, your data. Cancel any time.

Why Postelist

Own your sending. Keep your data.

No kill-switch

Mainstream providers can suspend a legitimate sender overnight for its industry or jurisdiction. A private, dedicated server removes that single point of failure.

Your data, full stop

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.

Built-in list validation

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.

Real people, not a dashboard

We provision, configure, and authenticate your server end to end, set up by people who run email infrastructure for a living, not a dashboard you are left to figure out alone. Once it is live it runs on its own, and our team is there whenever you need us.

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.

Questions, answered

Before you book

What happens to my deliverability during migration?

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.

Is my data really mine?

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.

What if I’ve been suspended or banned by another provider?

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.

How fast can I go live?

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.

How is it managed, and what about uptime?

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.

How does the guarantee work?

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.

What does it cost?

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.
