Disposable or Temporary Email
Short-lived addresses (Mailinator, Tempmail) that expire in minutes and break nurture flows.
Fake Email Checker
Instantly spot disposable, burner, and fraudulent email addresses before they enter your CRM, marketing automation, or product trial.
Understand What “Fake Email” Really Means
People use the phrase fake email to describe two very different things. Email Insights focuses on the identity signals living inside the address itself, not the message content that might appear later.
1. Fake Email Addresses (What Email Insights Detects)
These are identities designed to hide who the user is, bypass validation, or automate account creation. Email Insights analyses the address before any message is ever sent so intent surfaces in real time.
Types of Fake or Risky Addresses
Synthetic or Burner Addresses
Randomly generated identities that never deliver mail and help bots probe gated experiences.
Aliases or Masked Inboxes
Plus-aliasing and catch-all mailboxes that hide intent; pattern cues reveal the real risk.
2. Fake Email Content (Phishing, Spoofing, Malicious Copy)
This is what sits inside an email: the message body, attachments, and links. It is a separate layer of defence typically handled by secure email gateways or phishing-detection tools.
