For email, the value is the clean IP and inbox placement, not CPU or RAM. Sending is light on resources; what matters is IP reputation and authentication.
- Dedicated, clean IPs
- Each plan gives you 1 to 5 dedicated IPs, so you never share sending reputation with anyone else
- Port 25 open, rDNS preset
- Reverse DNS and SPF, DKIM, DMARC are configured at handover so receivers accept your mail
- Sending stack preinstalled
- PowerMTA or Postfix ready to go, integrates with MailWizz and Interspire, with full root access
- IP warmup guidance
- A schedule to warm a new IP gradually and build reputation, so it does not burn out on day one
Ready to send on login, full root behind it
SSH in and the SMTP stack is already running on a clean, dedicated IP with port 25 open. PowerMTA or Postfix is installed and rDNS is set to your hostname, with SPF, DKIM and DMARC preset. You still hold full root, so you tune the MTA, connect MailWizz or Interspire, and follow the warmup schedule at your own pace. An estimated 1.500 emails per hour per IP after warmup, depending on list quality, content and reputation.

Built for real senders
Every use case here sends to an opt-in list you own. No purchased lists, no cold outreach.
- Email marketing at volume
- Run campaigns to your own subscriber list on your IPs, instead of paying a SaaS per email
- Transactional email
- OTP, receipts and notifications from your app that need a stable dedicated IP
- Separate sending streams
- Put transactional and newsletter traffic on different IPs so one does not affect the other
- Own the full stack
- Keep the whole sending pipeline on infrastructure you control, not a closed platform
What keeps an IP alive
A clean IP stays clean only if it is sent the right way. These are the conditions on both sides, stated plainly, because a serious provider protects the whole pool.
We provide a clean pool and port 25
IPs are checked and not blacklisted at handover, port 25 is open on our side, and each IP gets a correct rDNS record. An IP that is already blacklisted cannot reach the inbox, so this is a condition we hold.
You bring a domain and an opt-in list
You need a sending domain to set SPF, DKIM and DMARC, and an opt-in list. No purchased lists and no spam. This is the condition that keeps the IP alive.
Warm the IP before full volume
A new IP has to be warmed up gradually, not opened at full volume on day one. We give you the schedule; we do not promise a 100 percent inbox rate.
Abuse policy protects everyone
Spam, purchased lists and deceptive content are prohibited. Violations are suspended to protect the reputation of the whole pool. This is deliberate, and it is why the IPs stay clean.
