How to Set Up Mailwizz with a Bulletproof SMTP Server for High-Risk Email Campaigns

Mailwizz Setup with Bulletproof SMTP Server

If you’re sending high-risk emails like affiliate links, spam, or grey-area offers, you need two powerful things:

  • A bulletproof SMTP server that never gets suspended
  • A reliable email automation tool like Mailwizz

In this guide, you’ll learn how to integrate both safely and effectively — even if you’re a beginner.

✅ What is Mailwizz?

Mailwizz is a self-hosted email marketing application. Unlike tools like Mailchimp or ConvertKit, you own the software and send campaigns from your own server.

That gives you:

  • Full control
  • Zero restrictions
  • Custom bounce handling
  • No bans for high-risk content

Pair this with a bulletproof SMTP server, and you have a setup that can’t be taken down.

✅ Why Use a Bulletproof SMTP Server?

A bulletproof SMTP server is built to handle:

  • Spam campaigns
  • Blackhat or greyhat affiliate promotions
  • Cold emails to scraped lists
  • Adult offers, casinos, CBD, crypto, etc.

It is non-suspendable, meaning even if you send millions of risky emails, your service stays online.

Step 3: Add Your Bulletproof SMTP

In Mailwizz:

  1. Go to Servers > Delivery Servers > Create New Server
  2. Select SMTP type
  3. Add:
    • Hostname: (your SMTP host)
    • Username & Password: (SMTP login)
    • Port: 587 or 2525 (start with open port)
    • Encryption: TLS or None
  4. Save and validate

🧠 Tip: Use custom “From Name” and rotate domains to increase inbox rate.

Step 4: Warm Up Your SMTP

Don’t send 10,000 emails on Day 1. Let the system warm-up:

  • Day 1–3: 50–100 emails
  • Day 4–7: 200–500 emails
  • Day 8–14: Slowly reach 1k–5k+

💡 Use our email warmup service — built into all bulletproof SMTP plans.

Step 5: Create a Campaign

In Mailwizz:

  • Upload your email list (cleaned list only)
  • Use short, clean subject lines
  • Avoid words like “free”, “guarantee”, “winner”
  • Schedule for low-competition hours (6 AM – 9 AM)

✅ Use inbox seed tracking tools
✅ Never use your main website domain to send cold emails
