Before you connect
Questions about Listclean.
The practical details behind the request, access and result.
How does Listclean help my email deliverability?
Listclean helps by identifying risky, disposable, and catch-all emails before you send your campaign. This reduces your bounce rate and protects your sender reputation.
Can I verify large lists of emails with Listclean?
Yes, you can process batches of up to 3,000 emails in a single request. This makes it easy to clean large databases quickly.
What happens if an email is marked as risky in Listclean?
A risky status usually means the email is a catch-all or a role-based address. It is safer to remove these from your primary outreach list to ensure higher deliverability.
Can I see the history of my verifications?
Yes, you can retrieve logs of previously verified single emails to see what was checked in the past and review your activity.
Is Listclean good for cleaning my CRM?
It is an excellent way to keep your CRM data high-quality. You can use your agent to periodically scrub your lead lists to remove dead or risky contacts.
How many emails can I check at once?
You can check up to 3,000 emails in a single batch request, making it efficient for large scale data hygiene.
What do the statuses 'clean' and 'dirty' mean?
'Clean' means the email address is valid and safe to send. 'Dirty' means the email is invalid, non-existent, or highly likely to bounce.
How many emails can I verify at once?
The verify_batch_emails capability supports JSON arrays. It is recommended to keep batches under 3,000 emails per request for optimal performance.
Where do I find my API Key?
Log in to your Listclean dashboard and navigate to Account Settings or Profile to find your unique X-Auth-Token.
