- 24/7 support
Park SMTP Gateway is a high-availability SMTP relay service for business and personal use, built on reputable IP addresses that have been in regular use for many years. By keeping your outgoing email out of spam folders, it maximizes your inbox delivery rate. It prevents the IP addresses of your in-house servers from being blacklisted and keeps your email flowing without interruption.
For high-volume sending such as campaigns and newsletters, see our bulk mail server plans. You can check your sending authentication with our SPF, DKIM and DMARC lookup tools.
Why Park SMTP Gateway?
IP reputation is the most critical factor when you send business email. Email sent from your own server can be flagged as spam because of shared IPs or blacklist problems. With Park SMTP Gateway, your email leaves from reputable, clean IP addresses, which ensures a high delivery rate.

- High availability: if one server goes down, another takes over
- Keeps your company IP address off blacklists
- Per-user sending limits and blocking of uncontrolled outbound mail

Frequently asked questions
Common questions about SMTP Gateway.
What is an SMTP gateway?
An SMTP gateway is a mail relay service that sends your email through intermediary servers with reputable, clean IP addresses instead of your own server. This increases the share of your email that reaches the inbox.
Why should I use an SMTP gateway instead of sending from my own server?
Your own server's IP address may have been tainted in a shared environment or may end up on a blacklist. SMTP Gateway uses reputable IPs that have been kept clean for many years, so your email is not flagged as spam.
How is high availability achieved?
Park SMTP Gateway consists of several servers. If one server has an outage, sending is automatically redirected to another server, so your mail flow is not interrupted.
How does blacklist protection work?
Because your email leaves from Park Gateway's reputable IP addresses rather than your company IP, your company IP does not end up on blacklists. The gateway IPs are monitored continuously and kept clean.
How do I integrate it with my existing mail server?
Simply add the Park Gateway server details to your mail server's SMTP relay settings. Our technical team helps you during setup.
Does it support SPF, DKIM and DMARC?
Yes. Park SMTP Gateway supports all modern email authentication protocols (SPF, DKIM, DMARC), which improves the trustworthiness and delivery rate of your email.
Can I control sending per user?
Yes. You can limit your users' sending and block uncontrolled bulk mail, which protects your IP reputation.
Is it suitable for business and personal use?
Yes. Park SMTP Gateway suits both companies and individual users. It can be configured specifically for the needs of your project.
