Verify the validity and existence of up to 50,000 email addresses in one go with our bulk email validation tool.
There’s no need to validate email addresses one by one with our bulk email verification tool. You can upload up to 50,000 email addresses in one go, saving you time and effort.
Our bulk email validation tool is not complicated. Simply upload your email list in CSV format and download the result in CSV, XML, or JSON formal—whichever suits you.
Aside from checking for syntax errors and common typos, the bulk email verification tool can detect email addresses from over 2,000 disposable email providers, including GuerillaMail, 10MinuteMail, and Mailinator.
Make it a habit to run your email marketing list through our bulk email verification tool to ensure that it is clean and free from invalid and nonexistent email addresses. The tool detects syntax errors and disposable email domains, which can drastically affect crucial email marketing metrics, such as open and bounce rates. By cleaning your email list, you can improve these metrics.
Monitor your subscriber list for faulty signups and typos using our bulk email validation tool. Abusive users may use invalid or disposable email addresses to take advantage of freemium features without the intention of upgrading their accounts.

Make email validation part of your cybersecurity best practices and detect threat actors who often use invalid and disposable email addresses to ensure anonymity when they launch spam and phishing campaigns.
