The Complete Guide to Mass Mailing for Card Collection

[Professor]

Buying cards these days is a nightmare. You spend money on premium cards only to be rejected or find out the same crap has been resold 50 times. That's why I started the Self-Carding series — to help you break free from dependence on shady sellers and become your own source.

The truth is, carding is getting expensive with all the proxies and anti-detection software. But having the skills to find your own cards gives you a huge advantage — lower costs and independence from shops that could go out of business any day.

PART 1: THE PHILOSOPHY OF SPAM​

1.1 To spam or not to spam?​

Email spam has been a reliable source of new cards and bank accounts since the dawn of the internet. While other methods come and go, spam campaigns consistently generate revenue because people are still foolish enough to fall for them. Every day, thousands of idiots enter their card details on phishing pages, thinking they're updating their PayPal accounts or paying fake bills.

It's a pure numbers game — send enough emails, and you'll find targets willing to hand over their financial information. Modern tools allow you to target millions without being detected. With basic social engineering, you can craft messages that bypass filters and evoke the perfect balance of urgency and trust. Unlike other techniques that require constant adaptation, the fundamentals of spam haven't changed — people fall for the same psychological triggers they always have.

1.2. The Spam Economy​

Parameter	Meaning
Cost of 1M letters	$50-200 (SMTP)
Conversion	0.01-0.1%
Average bill	$500-2,000
ROI	500-5,000%
Time for a campaign	2-7 days

Calculation example:

• 1M emails x 0.05% conversion = 500 cards
• 500 cards × $500 = $250,000
• Costs: $200 (SMTP) + $100 (domains) + $50 (software) = $350
• Net Profit: $249,650

PART 2: ABOUT THE SERIES​

I'll be honest — I spent weeks quickly mastering modern spam techniques and testing what still works in 2024-2026. While some aspects have changed, the fundamentals remain damn strong.

Note: This series is exclusively about spam techniques. Phishing is a separate beast, which I'll cover separately. Here, we're focusing on getting your emails into inboxes at scale.

This series consists of three parts:

1. Basic Concepts and Fundamentals
2. Practical step-by-step instructions for your first campaigns
3. Advanced Security Bypass and Scaling Techniques

No theoretical nonsense - just real, practical knowledge that will help you master mass mailing.

PART 3: INBOX IS THE ONLY GOAL​

Let's get right to it: spam is one thing — getting your damn email into someone's inbox. That's it. That's the whole game.

Not the spam folder. Not the promotions tab. In their real damn inbox, right between the invite to Karen's book club and the Amazon delivery notification. Everything else — the clever subject lines, the fake domains, the HTML formatting tricks — is just supporting roles.

Imagine breaking into a house. You can have the most sophisticated tools and plans, but if you can't get through the front door, you're just a pathetic bastard standing outside. Same with spam — all your brilliant scam ideas mean nothing if your email gets trashed by spam filters.

Every decision you make should answer one question: Will this help my email get into their inbox? If not, you're wasting your time.

PART 4: THREE MAIN COMPONENTS​

4.1. Your sending infrastructure​

SMTP servers​

SMTP servers are the foundation of email delivery across the internet. They manage the routing and delivery of your spam campaigns. Email providers track the reputation of each server based on its sending history and IP address — this directly impacts whether emails reach your inbox.

SMTP server options include:

Type	Pros	Cons
Carded hosting	Cheap, clean IP	Port 25 blocking, limits, tracking
Compromised SMTP	Cheap, a lot	Some IPs are flagged
Own infrastructure	Full control	Expensive, complicated
Hacked business servers	Established reputation	Risk of detection

Recommendation: The best approach is to use compromised SMTP credentials from hacked servers and websites. Outdated WordPress installations and misconfigured business servers provide easy access. Telegram botnet operators sell access to thousands of these hacked relays at a low price.

Important: Each SMTP has limitations — daily limits, hourly limits, or bandwidth bottlenecks. After a few thousand emails, most start queuing with delays of hours or even days. You need at least 20-30 SMTPs for serious volume. For a million-email campaign, each SMTP should process approximately 75,000 emails in 24-48 hours before the queues become overloaded.

Advanced spammers build their own SMTP infrastructure using secure hosting or hacked cloud accounts. This requires more initial setup but provides complete control. Compromised business email servers are especially valuable — their discovered sending history translates into improved deliverability rates for your phishing campaigns.

Domain Management​

Your phishing domains must appear squeaky clean to email providers. This means correct records and valid SSL certificates — all the technical stuff that verifies domain ownership and handles encryption. Without this foundation, your phishing emails are dead in the water.

What you need:

• □ SPF record
• □ DKIM signature
• □ DMARC policy
• □ SSL certificate
• □ Correct MX records
• □ Reverse DNS (rDNS)

Step-by-step domain setup:

1. Register a domain with a registrar (Namecheap, GoDaddy)
2. Configure DNS records:
   

   SPF: v=spf1 ip4:YOUR_IP include:_spf.google.com ~all
   DKIM: v=DKIM1; k=rsa; p=YOUR_PUBLIC_KEY
   DMARC: v=DMARC1; p=none; rua=mailto:admin@yourdomain.com

3. Install SSL (Let's Encrypt is free)
4. Set up rDNS through your hosting provider
5. Warm up your domain by sending 10-50 emails a day for the first week.

Email spoofing​

While this isn't as effective as it once was due to modern security measures like DMARC, the real payoff is making your phishing emails look like they're from legitimate services.

The old days of simply changing the "From" header are long gone. Now we have:

• SPF check
• IP authorization
• DKIM cryptographic signatures
• DMARC policies

But there are always loopholes:

Loophole	Description
Weak DMARC policies	Some ISPs accept emails even if checks fail
Unprotected subdomains	If parental policies don't cover them
Legitimate domains with SMTP	The Holy Grail is an existing reputation
Cousin domains	paypa1.com vs. paypal.com

Cousin domains are another trick. Register domains that at first glance look identical to legitimate ones (paypa1.com vs. paypal.com). Configure them technically correctly, and they will pass both automatic filters and human targets. If done correctly, your phishing addresses will look identical to real business emails — that's how you get those sweet banking credentials.

4.2. Your Email Lists (Leads)​

High-quality leads are incredibly important for phishing. New email lists perform better and avoid detection. Old addresses simply waste resources and burn out your infrastructure.

The best phishing lists include more than just email addresses:

List type	Conversion	Why
PayPal users	Very high	Verified accounts
Elderly people	Very high	Trusting, less tech-savvy
Bank clients	High	Spear phishing
Cryptocurrency exchange users	High	Tech-savvy but greedy
Random addresses	Low	Low conversion rate

Tip: A fresh list of email addresses verified as having PayPal accounts converts much better than random addresses. Another great example is a curated list of senior citizens' emails — they're pure phishing gold.

Where to get leads:

• Telegram channels with databases
• Forms on forums
• Data leaks
• Social media parsing
• Buy from trusted sellers

4.3. Software for mass mailing​

This is your command center. Premium tools like Atomic Mail Sender and Advanced Mass Sender handle everything: server rotation, phishing templates, delivery tracking, and blacklist monitoring.

Advanced software features:

Function	Description
SMTP rotation	Automatic switching when locked
Pattern randomization	Remain unnoticed
Delivery tracking	What settings work?
Proxy integration	Hide your real IP
HTML templates	Phishing customization
Clearing the list	Removing dead addresses
Spam score check	Before sending

Modern programs include proxy integration to hide your real IP, custom HTML phishing templates, and list cleaning to remove dead addresses. Some even check spam scores before sending and automatically adjust content.

You need software that balances power and stealth. Basic tools explode with obvious patterns that are instantly flagged. Advanced programs randomize delays, slightly modify message content, and distribute the load across servers.

4.4. Modern sending platforms​

Modern problems require modern solutions. While SMTP servers and email software remain reliable options for experienced spammers, 2026 brings additional vectors — legitimate email platforms like Mailchimp, SendGrid, and Resend.

Advantages:

• Built-in analytics
• Established IP reputation
• Optimized delivery systems
• No need to manage infrastructure

Flaws:

• Strict ToS
• Quick blocking in case of suspicion
• Limited control

These are not necessarily better than traditional methods, just different tools for different scenarios.

PART 5: UNDERSTANDING SPAM FILTERS​

The other part you need to understand is what you're playing against. Spam filters are your biggest enemy, designed to disrupt your entire operation before it even begins.

Think of spam filters as bouncers at an exclusive club. They check everything about you before letting you in. Miss one check? Your ass goes to the spam folder.

5.1 Content Analysis​

Your first task is to make the message persuasive:

Badly	Fine
FREE URGENT CHECK in topic	Personalized, relevant topics
Obvious phishing links	Disguised links
Malicious attachments	Links to legitimate pages
Too many pictures	Balance of text and images
Copied templates	Unique content

Pro tip: Never use templates or emails that have been circulating for months or years. Google parts of your message — if they appear on anti-scam sites, they're already blacklisted. Rewrite everything in your own words, maintaining the basic concept.

5.2. Technical inspection​

This is where most newbies make mistakes:

Error	Consequence
One IP for thousands of emails	Instant ban
The domain was registered yesterday	Low trust
No SPF/DKIM/DMARC	Failure of inspections
Dishonest falsification of headlines	Flag
Lack of SSL	Flag

5.3. Behavioral patterns​

Filters track how you act:

Pattern	Problem
10,000 emails in 5 minutes	Obvious spam
Recipients mark as spam	Reputation is falling
One server too long	Flag
Reusing blocked IPs	Instant ban

5.4. Recipient Behavior​

The final boss is real human behavior:

Behavior	Meaning
Real bank letters are read	Yours are deleted in 2 seconds
High spam reports	Reputation destroyed
Nobody clicks on the links	Campaign failed
Zero additions to contacts	No trust

Remember: Every failed campaign teaches you something. Modern filters are smart as hell — they share intelligence like cops share photos. One mistake and you're burned. Take your time, study the patterns, and always test before sending out in bulk.

PART 10: KEY FINDINGS​

Bro, email spam isn't for the faint of heart. You're going up against corporate security services with endless resources. Every successful campaign is a victory, but yesterday's tricks are tomorrow's red flags.

Key takeaways:

1. Inbox is the only goal - everything else is secondary
2. SMTP infrastructure - 20-30 servers are needed for the volume
3. Domains with correct records - SPF, DKIM, DMARC are required
4. Quality lists - conversion depends on leads
5. Randomization is the key to bypassing filters
6. Monitoring - Test Before Bulk Sending
7. Adaptation - yesterday's tricks don't work today
8. Domain warming is essential for reputation

Strategy:

• Start small (100 letters)
• Test every campaign
• Monitor your reputation
• Change SMTP and domains
• Adapt or die

Risks and their minimization:

Risk	Minimization
SMTP ban	Rotation, 20-30 servers
Domain ban	Cousin domains, frequent change
Spam filters	Randomization, warm-up
Low conversion rate	Quality lists
Legal	Anonymity, proxy

Remember: Adapt or die. That's the only rule that never changes.

Good luck, brother. If anything happens, ask.
