How to Get a High-Deliverability SMTP for Spamming & Red Teaming (Private Method)

SMTP for Spamming: Let me guess. You’ve tried to get a reliable SMTP for your red teaming exercises, penetration testing, or—let’s just call it what it is—spamming. And what happened? Nothing worked.

I’ve been there. I struggled for over a year, trying every method, every shortcut, every forum trick some guy named “Haxx0rJoe” recommended. And guess what? Every single attempt either failed outright or got me limited and banned faster than I could say “unsubscribe.”

But then, after relentless research and probably more caffeine than legally recommended, I stumbled onto a private method—one that works. And today, because I’m feeling weirdly generous, I’m sharing it with you for free.

But don’t get too excited. This isn’t as easy as pushing a button and spamming the world. Nope. It takes planning, patience, and a bit of finesse.

Tools You’ll Need to Get Started

Before you dive headfirst into this, here’s what you’ll need:

A valid domain name
Buy yourself a domain. No, you can’t use your Gmail account for this.
An email address tied to that domain
Something like [email protected]. This makes you look legit (or at least semi-legit).
SMTP service account from providers like SendGrid, Mailgun, or SMTP2Go
Here’s the trick:
When signing up, use the domain-based email you created. If you use some random email, you’re setting yourself up for failure.
A premium package with a dedicated IP
Go big or go home. A package that supports 50k+ emails per month is your best bet. If you’re on a budget, start with 50k, but I recommend 100k+ for fewer restrictions and better deliverability.

Once you’ve got your SMTP account, domain, and dedicated IP ready, bring them to us. This is where the magic happens. I’m talking about the secret sauce that transforms your SMTP into a finely-tuned machine ready for red teaming—or, you know, spamming. Contact Telegram: @spamtoolsorg for

What Is SMTP Warming (And Why Should You Care)?

Imagine showing up at a gym, grabbing the heaviest weight you can find, and trying to lift it cold. Bad idea, right? That’s how SMTP warming works.

SMTP warming is the process of gradually increasing the volume of emails sent through your new SMTP server. Why? Because email providers (like Gmail, Outlook, etc.) are very suspicious of new IPs that start blasting out thousands of emails out of nowhere.

Without warming, your emails go straight to spam folders—or worse, your SMTP gets shut down before you can even send your first phishing… I mean, penetration testing campaign.

By slowly ramping up the volume, you build trust with email providers. You’re like, “Hey, I’m a responsible sender! Totally not a spammer!” And they believe you. (For a little while, at least.)

The SMTP Warming Process: Our Secret Sauce

Sure, you could warm your SMTP manually, but why waste time? When you bring your SMTP and domain to us, we handle the warming process for you. We make sure your IP reputation improves, your domain gains credibility, and your setup becomes ready for the real action.

But here’s the catch: even with a perfectly warmed SMTP, the moment you switch into beast mode and start sending huge volumes of emails, you will eventually get banned.

That’s just the game.

How to Avoid Getting Banned (For As Long As Possible)

Here’s how to keep flying under the radar:

Start slow – Send around 100 emails on day one.
Double your volume daily – Next day? Send 200 emails. Then 400, then 800, and so on.
Work up to your limit – Once you’re hitting those higher numbers (50k+), then you can start blasting.

But remember:

Even with warming, spamming at high volumes eventually gets noticed.
Your SMTP account might get limited or suspended after a while, but not immediately—which gives you valuable time to run your campaigns.

Pro tip: Always have another SMTP account warming in the background. That way, when one goes down, you’ve got the next one ready to roll. Stay ahead of the game.

Final Thoughts: This Method Is Private (But Now It’s Yours)

This isn’t something you’ll find floating around on Reddit or some random hacking forum. This method took a year of trial and error to perfect. And now, I’m giving it to you.

So, whether you’re doing red teaming, penetration testing, or just feel like blasting the inboxes of the innocent, you’re now armed with the secret method to make it happen.

But remember, with great power comes great responsibility—or at least, the inevitable suspension of your SMTP account.

Stay sneaky, stay prepared, and warm those servers right.
