Before you connect
Questions about NeverBounce.
The practical details behind the request, access and result.
How does the NeverBounce MCP help with my email deliverability?
It keeps your sender reputation high by identifying and removing invalid, disposable, and dead email addresses before you send your campaigns. This reduces your bounce rate and helps keep you out of spam folders.
Can I use NeverBounce to clean my CSV files automatically?
Yes, you can provide a URL to a remote CSV file and have your agent start a bulk verification job. It will process the list and give you the results once it's finished.
Is there a way to check single emails quickly with NeverBounce?
Absolutely. You can just ask your agent to check a single email address in real-time. It will tell you if the address is valid or if it has any deliverability issues.
How do I know how many credits I have left on NeverBounce?
You can simply ask your agent to check your account info. It will pull your current credit balance and list your recent verification jobs so you can track your usage.
Can the NeverBounce MCP handle thousands of emails at once?
Yes, it is designed for bulk processing. You can create jobs from raw text or URLs, and the agent will manage the verification of thousands of addresses in a single batch.
What happens to the data after I run a NeverBounce job?
Once a job is complete, your agent can fetch the results for you. You can then use that clean data for your marketing campaigns or import it into your CRM.
Where do I find my NeverBounce API Key?
Log in to your NeverBounce dashboard and navigate to the API section to create or copy your 'Secret Key'.
What do the different result statuses mean?
'Valid' means the email is safe to send. 'Invalid' will bounce. 'Disposable' are temporary addresses, and 'Catchall' means the domain accepts all mail, making deliverability uncertain.
How do I start a bulk verification job?
First, use create_job_from_url or create_job_from_input. Then, call parse_job followed by start_job to begin the verification process.
