- Disposable/temporary emails (e.g., tempmail.com users)
- Incorrect or inactive phone numbers
- Bots filling out lead forms
- Spam submissions with invalid data
1.2 Where Do Fake Leads Come From?
Fake leads can enter your system in multiple ways, including:
🛑 Fraudulent Signups – People enter fake info just to access free trials, downloads, or gated content.
🤖 Bots & Spammers – Automated scripts fill out forms with fake details, flooding your CRM.
📢 Bad Ad Traffic – If you’re running ads, fake leads might come from click farms or low-quality traffic sources.
🎁 Giveaway Hunters – Some people use fake info to claim discounts, freebies, or bonuses without real intent.
🚫 Human Error – Typos and incorrect information also lead to bad contact details.
1.3 The Impact of Fake Leads on Your Business
Ignoring fake leads costs businesses thousands of dollars each year.
- 🛑 High Email Bounce Rates → Hurts your sender reputation, and emails end up in spam.
- 📉 Wasted Marketing Budget → Fake leads increase your ad spend without actual conversions.
