Best VPS with Open Port 25 for Sending Emails in 2026: My Top 9 Picks That Still Works

In my email server tutorials, I always use a VPS with open port 25 so that I can send emails.

In this article, I will share ten reputable VPS providers (which I’ve tested personally and or contacted their respective support) known for their open port 25 capabilities and are the best VPS for email servers:

Understanding Ports 25, 587, and 465

Ports 25, 587, and 465 are essential components of the Simple Mail Transfer Protocol (SMTP) and Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocols. These ports play crucial roles in the transmission and security of email communications:

1. Port 25: Standard SMTP port for email transmission.
2. Port 587: Submission port for email clients to send messages securely.
3. Port 465: Deprecated SSL/TLS port for SMTP over SSL.

Now, let’s explore the features of the VPS providers with an open port 25. Not sure if your VPS has open port 25? Check it using this tool.

Note: Servers will automatically open port 25 once an application (e.g., mailcow) that requires open port 25 is installed.

My top 10 best VPS for email servers! Note that these providers may change their email policy without notification.

1. isHosting (Unlimited Outbound Sending)

If you’re looking for a reliable VPS provider with flexible plans, global reach, and a wide array of features, ishosting is worth considering.

Below is a breakdown of what makes iShosting’s VPS services stand out — including port 25 availability, supported payment methods, and core VPS features.

Watch my step-by-step setup of isHosting VPS in Dallas.

Port 25 Access

isHosting controls port 25 access based on your plan level:

• Medium Plan and above: Port 25 is open by default, making these plans better suited for email servers and applications requiring unrestricted SMTP traffic.

Global Availability

Data Centers in 30+ Countries: Including locations in Europe, Asia, North and South America, and Oceania, allowing you to choose a server location closest to your target audience for optimal performance.

Key Features

• Open ports 25, 465 and 587

2. RDP Monster (Unlimited Outbound Sending)

RDP Monster is a low-cost VPS and RDP hosting provider known for fast provisioning, flexible payments, and privacy-friendly ordering. One feature that makes it stand out—especially for email server users—is its paid Open Port 25 option.

Open Port 25 (SMTP)

By default, port 25 is blocked, which is standard across most VPS providers to reduce spam abuse. However, RDP Monster allows you to open port 25 for an additional $5 fee.

⚠️ As with any VPS provider, opening port 25 means you are responsible for proper mail configuration, IP reputation, and avoiding spam-related abuse or blacklisting.

Key Features

• Open ports 25, 465 and 587
• Instant VPS / RDP activation after payment
• Root / Administrator access on Linux VPS and Windows RDP
• NVMe SSD storage on most plans
• High bandwidth allocations (often advertised as unlimited or generous caps)
• Multiple locations (varies by plan)
• No heavy KYC / verification, appealing to privacy-focused users

Payment Methods

RDP Monster supports a wide range of payment options, including:

• Cryptocurrency (XMR and all cryptos)
• USDT (TRC20)
• Coinbase Commerce
• Stripe (Credit card)
• Capitalist (WebMoney, Qiwi, YooMoney, Cards : RU, UAH, KZT…)

This flexibility is a big plus for international users and crypto-friendly buyers.

RDP Monster is a solid choice if you need a budget VPS with the option to open port 25, especially for testing or running self-hosted email servers. The $5 port-25 add-on is reasonable compared to providers that block SMTP entirely, but users should still follow best practices for email security and warm-up.

Take note that their support is through chat and Telegram.

3. NoBull Networks (Unlimited Outbound Sending)

When you’re choosing a VPS provider for hosting an email server or any application that needs SMTP, one of the first things you check is whether port 25 is open. NoBull Networks is upfront about its policy, and it’s a setup that balances security with flexibility.

Port 25 Policy: Blocked by Default but Can Be Opened

NoBull Networks blocks the following outgoing ports on all VPS plans by default:

• TCP 25
• TCP 465

Their reason is simple: these ports are commonly abused for spam and VoIP attacks. By blocking them initially, they protect their IP ranges from getting blacklisted.

The good news?

You can request to have these ports opened by contacting their support team. They typically ask for your use case to ensure it’s legitimate, which is standard practice among responsible hosting providers.

Pros of Their Port Policy

• Helps maintain a clean IP reputation

• Prevents spam and abuse on shared infrastructure

• You retain the option to run your own mail server

• Transparent policy—no hidden restrictions

NoBull Networks VPS Features 

• KVM Virtualization – Full isolation and strong performance

• NVMe SSD Storage – Fast read/write speeds

• Unlimited Bandwidth – With 1 Gbps network port

• Full Root Access – Total control over your server

• OS Choices – Linux distributions + Windows (for Windows VPS)

• SSD Volume Expansion – Scalable storage up to large capacities (managed)

• Managed VPS Option – Includes firewall, private networking, API/CLI tools

Payment Methods Accepted

NoBull Networks supports a wide variety of payment options, making it accessible for users worldwide:

• PayPali

• Stripe (Visa, Mastercard)

NoBull Networks VPS Plans

NoBull Networks offers a secure, transparent, and flexible solution for users who want to run email servers or any application requiring SMTP. Their port-25 policy is reasonable, and the option to request unblocking makes them more accommodating than providers that permanently restrict outbound SMTP.

Combined with multiple payment options and straightforward terms, they’re a solid choice for developers, email enthusiasts, and self-hosting users who need control but also want a provider that takes abuse prevention seriously.

4. DartNode (Unlimited Outbound Sending)

DartNode VPS is an affordable option for those seeking a cloud hosting solution, and it does allow port 25 to remain open, which is crucial for sending emails.

This feature makes it potentially useful for email marketing, especially for small-scale operations. However, it is important to note that email marketing success relies not only on port 25 being open but also on the VPS provider’s reputation for handling email services and avoiding IP blacklisting.

DartNode seems focused on performance with features like SSD storage and network upgrades, but it does not explicitly position itself as an email marketing VPS, so caution is advisable when using it for large-scale campaigns to avoid deliverability issues.
