What is email verification?
Our Email Checker validates whether an email address is real, active, and free of common mistakes. The tool checks syntax, verifies the domain and mail server, and confirms whether the mailbox can receive messages — all without sending an actual email.
Why verify emails?
- Prevent hard bounces: Remove invalid addresses before sending campaigns.
- Protect sender reputation: Reduce bounce rates so your messages land in inboxes.
- Reduce spam complaints: Contact only engaged, valid recipients.
- Save time & budget: Focus outreach on real prospects and avoid wasted sends.
How it works
- Syntax check: Detects typos and invalid characters (e.g., misspelled domain or missing `@`).
- Domain check: Confirms the domain (example: `gmail.com`) exists and has mail servers.
- Mailbox verification: Checks deliverability without sending a message to the address.
