Invitation-only email hosting
ClubSMTP is a managed email hosting platform built around strict access control. Every account is administrator-provisioned. Every mailbox is monitored. No open sign-ups, no unknown senders, no shared reputation risk.
When one bad sender on a shared platform damages the IP reputation, everyone suffers — including you. ClubSMTP eliminates that risk at the door.
Every account is created by an administrator. No one gets in without an explicit invitation. The platform stays clean because the people on it are known.
Every domain on the platform is continuously checked against required DNS records. SPF, DKIM, DMARC, autoconfig — status is always visible and always current.
Each mailbox has its own whitelist and blacklist. Control exactly who can reach each address — down to individual senders or entire domains, including wildcards.
The difference
A single bad actor on a shared platform can land your domain on a blocklist. ClubSMTP is built so that never happens — because every sender is known, every mailbox is monitored, and access is never open.
Sign in to your accountProvisioned by an administrator. Managed by you.
An administrator creates your account and sends you an invitation. There is no open registration. Access is always explicitly granted.
Connect your domain, verify DNS records, and provision mailboxes. Each mailbox is isolated with its own storage allocation, whitelist, and blacklist.
Your mailboxes operate on a platform where every sender is known. DNS health is monitored continuously so you always know where you stand.
A focused platform built around one thing — reputation-safe email hosting.
Add and manage your domains in one place. ClubSMTP continuously checks MX, SPF, DKIM, DMARC, autoconfig, and autodiscover records and shows you their live status — so you know immediately if something's misconfigured.
Provision mailboxes under your domains with defined storage allocations. Enable or disable individual mailboxes at any time. Billing is per mailbox, prorated to your account's billing anchor date.
Each mailbox has its own sender whitelist and blacklist. Rules support individual addresses, full domains, and wildcard patterns. Rules sync directly to the mail server in real time.
Full REST API for programmatic management of domains, mailboxes, aliases, and filter rules. Webhook events fire on every key action so your systems stay in sync automatically.
Pay only for what you provision. No base fees, no contracts.
Billed monthly to your anchor date
Per mailbox, per month
If you've received an invitation, sign in to get started. If you haven't, contact the administrator who referred you to ClubSMTP.
