This guide is for complete beginners who have never bought a VPS before but want to use Hetzner for email marketing and/or cold email.

By the end, you will know exactly which Hetzner Cloud instance type, datacenter location, operating system, and configuration to choose to run PowerMTA, Postfix, Exim or Postal safely. You can follow the steps even if you have zero server administration experience.

The 2026 Hetzner price increases: what email senders need to know

Hetzner raised cloud prices twice in 2026 and the impact is very uneven across their instance families. If you are researching Hetzner for email marketing today, this is the context you need before comparing plans.

• April 1, 2026 hike: broad adjustment of up to +37% across the portfolio, applied to new orders and existing customers alike.
• June 15, 2026 hike: targeted at the more powerful lines. Applies only to new orders and rescales (existing servers keep their prior terms).

The magnitude of the June 15 increase depends on which instance family you pick:

Bottom line for email marketers: the cost-optimized CX and CAX lines remain the best value for solo cold email and small-scale sending. If you need dedicated performance (CPX/CCX) for high-volume or agency workloads, run the math against OVH, Contabo, or DigitalOcean before committing to Hetzner in 2026.

Who should use this guide?

• Solo email marketers starting cold outreach from their own servers.
• Small agencies needing a cheap VPS to run SMTP for multiple clients.
• People moving from shared hosting to a self-hosted email server on Hetzner.
• EU-based senders prioritizing GDPR compliance and European datacenters.

Introduction: What is Hetzner?

Hetzner Online GmbH is a German company specializing in data center infrastructure and cloud hosting. It is one of the largest and most respected hosting providers in Europe, known for transparent pricing, excellent infrastructure quality, and strong privacy policies (GDPR-compliant).

Hetzner provides a wide range of solutions for individuals and businesses through their Hetzner Cloud platform. This type of hosting service is ideal for people who want full control over their email infrastructure with guaranteed GDPR compliance and premium data center quality.

The company was founded in 1997 and operates its own data center parks in Nuremberg and Falkenstein (Germany) and Helsinki (Finland). Unlike many competitors, Hetzner owns most of its infrastructure, ensuring consistent quality, reliability, and speed. They are known for honest pricing with no hidden fees, excellent performance, and a strong community.

Overview: The Basic Features

Hetzner Cloud VPS comes with several key advantages for email marketing:

• Unlike OVH or Contabo, port 25 available by request (requires first paid invoice, then support ticket)
• Unlimited traffic on all instances
• GDPR-compliant infrastructure in all EU datacenters (Germany, Finland)
• ISO 27001 certified data centers with high security standards
• Free DDoS protection on all instances
• NVMe SSD storage in RAID10 for data redundancy and speed
• 10 Gbit redundant network connections (enterprise-grade)
• Hourly billing with monthly price caps (no overage charges)
• Full API and CLI access for automation
• Reverse DNS configurable for email authentication
• Excellent community and responsive support
• Owned data centers in Germany and Finland (not colocation)

Hetzner offers exceptional value for email marketing infrastructure. Their infrastructure is enterprise-grade despite competitive pricing, making them ideal for serious email operations.

Step‑by‑Step: How to Choose the Right Hetzner Cloud Instance

Step 1: Choose the Right Hetzner Instance Type and Resources

Hetzner Cloud offers several instance types designed for different needs. The key distinction is between Cost-Optimized (CX), Regular (CPX), and Dedicated (CCX) instances.

Hetzner Cloud Instance Types Comparison:

Key Insight for 2026: After the June 15 price adjustment, the CX23 (€5.49/mo) and CAX11 (€5.99/mo) cost-optimized instances remain the best value for solo cold email and small-scale sending. Both use shared vCPU (Intel/AMD or ARM Ampere) but are more than sufficient for up to 50k emails/month. The regular-performance CPX22 (€19.49/mo, shared AMD) makes sense once you run multiple domains or need 80 GB storage. Note: CPX is shared AMD vCPU (not dedicated). Only the CCX line provides dedicated cores.

Common Use Cases and Instance Type Recommendations:

Cold Email Outreach (Up to 50k/month)

• Best instance: CX23 (€5.49/mo) or CAX11 (€5.99/mo)
• Why: Dedicated or shared vCPU both sufficient; 40-80GB storage adequate for logs; unlimited traffic covers moderate volume
• Setup: One IP, one domain, PowerMTA or Postal

Warm Newsletter (100k-300k/month)

• Best instance: CPX22 (€19.49/mo)
• Why: 4 dedicated vCores reduce queue processing time; 8GB RAM handles multiple campaigns; 80GB storage for logs and queue
• Setup: One or two IPs; can support higher concurrent connections

Agency or Multi-Client Setup (300k+/month or 5+ domains)

• Best instance: CPX32 or CCX13 (€42.99/mo), check hetzner.com for exact CPX32 price after June 2026
• Why: 8 vCores allow parallel processing for separate clients; dedicated CPU ensures no noisy neighbor issues; ample storage
• Setup: Separate IPs per client/domain; subdomain segmentation essential

Still unsure? Start with CX23 (€5.49/mo) or CAX11 (€5.99/mo, if your MTA supports ARM64). Both are the cheapest viable entry points in 2026 and will handle solo cold email comfortably. Upgrade to CPX22 or CCX13 only when you actually hit a bottleneck.

Step 2: Select Datacenter Location for Better Deliverability

Hetzner operates datacenters in 4 network zones and 6 locations. Choose wisely based on your audience.

EU Datacenters (Hetzner-owned, GDPR-native):

• Nuremberg, Germany (NBG1), Multiple facilities, excellent latency for EU
• Falkenstein, Germany (FSN1), Largest data center park (18 facilities), very stable
• Helsinki, Finland (HEL1), Nordic coverage, same EU compliance

US Datacenters (Colocation, not Hetzner-owned):

• Ashburn, Virginia (ASH), US East Coast, good for North America
• Hillsboro, Oregon (HIL), US West Coast, alternative US location

Asia Datacenter (Colocation):

• Singapore (SIN), Asian coverage. Traffic overage more expensive than EU (~€7.40/TB). CPX/CCX prices in Singapore rose less than in EU or US during the June 2026 hike, so this can be a cost workaround for dedicated-vCPU workloads.

Recommendation by Audience:

• EU-only or GDPR-required: Choose Nuremberg (NBG1) or Falkenstein (FSN1), both in Germany
• Mixed EU/US audience: Start with Nuremberg or Falkenstein; latency to US is ~100-150ms (acceptable)
• US-only senders: Choose Ashburn (ASH) for East Coast or Hillsboro (HIL) for West Coast
• Global operations: Use Nuremberg (EU base) + Ashburn (US base) with load balancing

Important Note: Hetzner datacenter parks in Germany and Finland are Hetzner-owned and operated. US and Singapore use colocation, but Hetzner owns the servers. This ensures consistent quality across all locations.

Step 3: Pick OS for PowerMTA or Postal

Your operating system choice depends on which email server (MTA) you plan to use. Pick one:

For PowerMTA (professional, feature-rich, paid):

• Choose: Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, or Debian 11+
• Why: Most stable; PowerMTA officially supports these; best community support
• Hetzner pre-installs: Ubuntu, Debian, Fedora, CentOS, AlmaLinux, openSUSE
• Recommendation: Ubuntu 22.04 LTS (newest stable LTS)

For Postal Email Server (free, beginner-friendly, modern):

• Choose: Ubuntu 22.04 LTS or Ubuntu 20.04 LTS (required)
• Why: Postal optimized for modern Ubuntu; web UI beginner-friendly; built-in bounce/complaint handling

Don’t know which one yet?
Start with Postal on Ubuntu 22.04 LTS. It’s free, requires less configuration, and works great on Hetzner’s infrastructure. You can always switch to PowerMTA later if needed.

Important Note: Hetzner allows you to select the OS during instance creation. The OS is fully customizable, and you get immediate root SSH access.

Step 4: Configure Networking and Request Port 25 Unblock

Hetzner Cloud comes with a web console and full networking control.

Critical step: Request port 25 unblock

⚠️ Important: Port 25 is blocked by default on new Hetzner instances for anti-spam purposes. Unlike OVH or Contabo, you must:

1. Create your instance and pay your first invoice (must have first paid invoice)
2. Wait a few days (optional, but recommended)
3. Open a support ticket requesting:

• “Enable outbound SMTP port 25 for mail server”
• “Unblock outbound ports 25 and 465”
• Mention your intended use (e.g., “self-hosted email marketing infrastructure”)

1. Hetzner support will typically approve within 24 hours if your account is clean

What to do in Hetzner Console:

1. Log into Hetzner Cloud Console → Your Instance → Network
2. Note your primary IPv4 address (you’ll need this for reverse DNS)
3. Set Reverse DNS (PTR record):

• Go to Network → Floating IPs or primary IP
• Set PTR record to your domain (e.g., mail.yourdomain.com)
• This is critical for email deliverability

1. Configure Firewall Rules if needed (optional; all ports open by default)
2. Request additional IPs if needed (per-IP add-on pricing)

Port Status Initially:

• Port 25 & 465: Blocked (outbound) until you request unblock
• Port 587: Open (submission port, works immediately)
• Port 143/993: Open (IMAP, for receiving)
• Port 110/995: Open (POP3, for receiving)

Workaround if port 25 takes time: Use port 587 (submission port) with STARTTLS on your MTA temporarily, or use an SMTP relay (smtp2go, Brevo) until port 25 is enabled.

Step 5: Check IP Reputation and Blacklists

Hetzner IP Reputation Overview:
Hetzner IPs have decent reputation overall, but less generous than some providers. Their strict anti-spam policies mean new IPs start clean, not blacklisted.

Your Hetzner IP will be checked against blacklists immediately after provisioning. Hetzner is proactive about IP reputation management, which is good for legitimate senders.

CRITICAL RBLs to worry about:

• Spamhaus (SBL, PBL, ZEN)
• SORBS
• Barracuda Reputation
• Microsoft Outlook/SmartScreen (internal)

Non-critical RBLs (don’t stress):

• UCEPROTECT Level 3 (major ISPs ignore this)
• Community-run lists with poor accuracy

What to do:

1. Check your IP on launch day:

• Use MXToolbox, AbuseIPDB, or Spamhaus Lookup
• Screenshot your baseline so you can track changes

1. Once port 25 is unblocked:

• Test port 25 connectivity immediately
• Verify reverse DNS is working (use nslookup or dig)
• Run a test email send

1. Warm up properly to stay off major lists:

• Start with 100-200 emails/day, increase 20-30% every 2-3 days
• Use a warmup tool first 2-3 weeks
• Monitor bounce rates and spam complaints daily

1. Avoid low-quality lists:

• List quality is #1 factor for blacklisting
• Verify all leads before sending (e.g: SMTPing, Zerobounce)
• Monitor complaint rates religiously

1. If you get listed on a major RBL:

• Request a delisting immediately (most allow self-service)
• If denied, contact Hetzner support; they advocate for customers
• As a last resort, request a different IP (may be charged per IP after first IP)

Hetzner’s perspective on IP reputation:
Hetzner maintains relatively strict but fair policies. New IPs start clean. The company proactively monitors for abuse. If you maintain proper authentication (SPF, DKIM, DMARC) and avoid spam complaints, your IP should remain in good standing. Hetzner support is responsive to legitimate email senders.

Alternatives if Hetzner is now too expensive for your workload

The June 2026 CPX and CCX price hikes have closed much of Hetzner’s price advantage for dedicated-vCPU workloads. For email marketing specifically, the following EU-based alternatives are worth benchmarking before committing to a Hetzner CPX22 (€19.49/mo) or CCX13 (€42.99/mo):

For pure GDPR compliance with the lowest 2026 pricing, OVH Cloud (French, port 25 open, cheap) is the strongest Hetzner alternative for solo cold email. For agencies running dedicated-vCPU workloads, benchmark Contabo against Hetzner CCX before committing.

Frequently Asked Questions

I want to install PowerMTA on my Hetzner instance, which OS should I choose?

You can select Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, or Debian 11+. Preferably Ubuntu 22.04 LTS as it’s the newest stable LTS. During instance creation, you’ll select the OS image. After instance launches, SSH in and install PowerMTA from source using official documentation.

Can I use Hetzner for PowerMTA?

Yes. PowerMTA works great on Hetzner. Choose Ubuntu 22.04 LTS during provisioning. After your first paid invoice and port 25 unblock (24-48 hours), you’re ready to send. Hetzner support is responsive if you need help enabling port 25 or configuring reverse DNS.

Which Hetzner instance type is best for cold email?

After the June 2026 price hikes, the answer depends on your volume. For solo cold email (up to 50k/month), CX23 (€5.49/mo, 2 shared vCPU, 4 GB RAM, 40 GB NVMe) is the cheapest viable option; CAX11 (€5.99/mo ARM) if your MTA supports ARM64. For multi-domain or 100-300k/mo sending, CPX22 (€19.49/mo, 2 shared AMD vCPU, 4 GB RAM, 80 GB) is the go-to. For 300k+/mo or agency workloads, CCX13 (€42.99/mo, 2 dedicated AMD) or higher. Note: the article’s original recommendations for €5.99 CPX11 predate the 2026 hikes.

Is Hetzner good for cold email deliverability?

Yes. Hetzner is reliable for cold email if you follow best practices: warm up your IP gradually, use high-quality lists, monitor bounce rates, and maintain proper authentication (SPF, DKIM, DMARC). Hetzner’s enterprise infrastructure and proactive IP management support legitimate email operations well.

Do I need a dedicated IP on Hetzner for email marketing?

Hetzner provides one IPv4 address per instance by default. For cold email, one IP is fine when starting. As you scale, request additional IPv4 addresses (per-IP pricing varies by region, typically €1-3/month) and use subdomains to segment traffic per client or campaign.

Is port 25 blocked on Hetzner?

Port 25 is blocked by default on new Hetzner instances. This is different from OVH and Contabo. However, Hetzner unblocks it within 24 hours via support ticket after your first paid invoice. Port 587 (submission) is open immediately, so transactional email works right away.
