Frequently asked questions about email validity
Email verification is the only method that ensures that the emails you’re sending to are valid. Sending emails or email marketing campaigns to invalid emails results in high email bounce rates, which hurt your email domain and your ability to reach the inbox. If you can’t reach your subscribers, you won’t be able to engage, nurture, and convert readers into customers.
You can verify any email address using ZeroBounce’s free email verifier tool. Just enter the email address and get your result in seconds, which includes the email’s status, sub-status, and any other relevant information about the address and its owner when available.
If you fail to verify an email address, you have no way to determine if it’s real. When you send an email message to the address, it will either be delivered to the inbox or spam folder (if it’s real), or it will bounce back to you if the address is invalid. While the occasional bounce isn’t cause for concern, a high volume of bounces all at once or over time will negatively impact your email deliverability.
All businesses need email verification on their website to control the type of data that’s submitted to their database. Without any form of verification, any visitor can enter any data, which then makes it onto your email list. At best, this fake data will be invalid and result in an email bounce. At worst, hackers and spoofers can use specific data entries to inject programming languages, which effectively create an unauthorized backdoor into your site or platform. The attacker can then access private business or customer data without your knowledge.
