Frequently Asked Questions
Find answers to common questions about email verification.
How do I know if an email address is fake?
Check for format errors (missing @ symbols, wrong domain extensions), verify the domain exists and has mail servers, and search online for evidence of the address. The most reliable method is using an email verification tool that pings mail servers without sending actual emails. This is the safest way to determine how to check if an email is valid.
Can I check if an email is valid without sending an email?
Yes, and it's the safest approach. Email validation services perform SMTP handshakes to ask servers, "Does this mailbox exist?" without delivering any message. This avoids reputation damage from bounced test emails while providing accurate results in seconds.
How often should I verify my email list?
Clean your list every quarter or at least twice yearly. Email addresses decay continuously, with lists losing about 2% validity monthly. Regular cleaning prevents bounce accumulation and maintains high deliverability rates.
