Frequently Asked Questions

How does the Email Checker tool work?

The Email Checker tool verifies email addresses by analyzing their status. Simply enter an email address, click "Check email address," and instantly receive one of four results: Deliverable, Risky, Undeliverable, or Unknown.

What do the status results mean?

- Deliverable: The email address is valid, and messages will likely be delivered successfully.
- Risky: Sending emails to this address might result in a bounce or low engagement. It’s best to avoid it.
- Undeliverable: The email address is invalid or misspelled. Remove it from your list or double-check the details.
- Unknown: The email provider didn’t respond. Avoid for now or try again later.

Why should I verify email addresses before sending?

Unverified emails can lead to high bounce rates, which harm your sender reputation and reduce deliverability. This can cause more emails to land in spam folders or fail to deliver altogether, wasting resources and campaign efforts.

What can I do if an email turns out undeliverable?

Use lemlist’s email permutator to generate potential email variations based on the lead’s first name, last name, and company. Then verify the suggested emails to find the correct one.

Can I verify email lists in bulk?

Yes! With lemlist’s tools, you can verify multiple emails at once by uploading a list. Additionally, the People database provides a directory of over 450 million leads with verified email addresses, filtered by job title, industry, and more.

Is there a limit to how many emails I can check for free?

Yes, there is a limit to the number of emails you can check for free. If you need to verify emails in bulk, you should start a free trial with lemlist. This will allow you to check more emails and find additional leads with our B2B lead database.

How accurate is the email checker?

The tool strives to provide the most accurate email addresses by using current databases and sophisticated algorithms. This ensures a high level of accuracy in verifying the validity of email addresses.
