An invalid email address results in communication failures and missed opportunities. Due to deliverability issues such as inactive or invalid email addresses, 20% of emails don’t reach the inbox. To improve your email bounce rates, ensure you’re reaching out to the right email with lemlist’s free email checker tool.

How to use lemlist’s free email checker tool

How to check if an email is valid in just 3 steps:

1. Type in the email address that you want to verify
2. Click on the Check email address button
3. Check the status
Here’s how safe it is to send an email to that address depending on the result:
- Deliverable: The recipient’s email provider has confirmed that the address exists so you can email this address.
- Risky: Sending an email to this address may result in a bounce or low engagement.
- Undeliverable: The address doesn’t exist, or you misspelled it.
- Unknown: lemlist couldn’t get a response from the email provider. Best not to reach out to the email address.
