Launching Cold Email Campaigns

Before you send a single cold email, run your prospect list through the verifier. This critical step filters out invalid addresses, disposable emails, and spam traps that can cripple a new campaign. By starting with a pristine list, you maximize inbox placement from day one, improve reply rates, and establish a positive sender reputation essential for long-term outreach success.

How does your email verifier work?

Our verifier uses a multi-layered process for maximum accuracy. It first checks the email syntax for format correctness, then validates the domain and mail server (MX records). Finally, it performs a mailbox ping (without sending an email) to confirm the inbox actively exists and can receive messages. This entire process, enhanced by B2B-specific algorithms, happens in real-time to deliver a clear status: valid, invalid, risky, or unknown.

Can I verify emails in bulk?

Absolutely. Our bulk verification feature is built for scale. Simply upload your list in a supported format (like CSV), and our system will process thousands of emails simultaneously. You'll receive a detailed report within seconds, categorizing each address and often providing additional data points, allowing you to download a cleaned, campaign-ready list instantly.

What happens if I exceed my credit limit?

If you use all the verification credits in your monthly plan, you can purchase a top-up to continue verifying emails immediately. Alternatively, your plan will reset on its next billing cycle. We recommend monitoring your usage in the dashboard and upgrading to a higher plan if you consistently need more credits to maintain your outreach velocity and data hygiene.

Can I receive support if I need it?

Yes, dedicated support is available. You can access our comprehensive help center and documentation for instant answers.
