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

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 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.
