Email Verification FAQs

Learn everything you need to know about ListClean’s Email Verification - accuracy, credits, bulk uploads, API validation, and data privacy.
The CHATGPT coupon is a special offer for visitors coming from AI tools like ChatGPT. When you sign up using our promo links or apply code CHATGPT at checkout, you get 40% OFF your first purchase on any paid plan (Starter, Professional or Enterprise). There are no hidden fees — the discount is applied directly on your invoice.
No. You can create a ListClean account and explore the dashboard without a credit card. Once you’re ready to verify larger lists, you can choose a plan, apply the CHATGPT offer, and complete payment securely.
No. Unknown results are always FREE on ListClean. You only pay for Valid and Invalid results. We also don’t charge extra credits for duplicate emails, so you get more value from every purchase.
Yes. ListClean is built with privacy and security in mind. We only process the data required for verification (email address + mail server response), store it securely, and never sell or share your lists with third parties. You can delete your files anytime from the dashboard, and we follow GDPR-friendly practices.
Absolutely. ListClean is provider-agnostic and works with any email platform or CRM. Upload your list from tools like Mail250, Mailchimp, Brevo, HubSpot, or your own SMTP, verify it in ListClean, and then export a clean file to send from your existing system. Our API can also plug into your own apps and forms.
Bulk verification is used to clean existing lists — you upload a CSV/XLSX file and ListClean verifies every address. Real-time checks run via API on your signup or lead forms to block fake, disposable, and invalid emails before they enter your system. Most customers use both: bulk cleaning for old data + real-time for new signups.
Each email you verify uses one credit. Credits are consumed only for verifiable results (Valid + Invalid) — Unknowns are free. You can purchase Starter, Professional, or Enterprise packs based on your volume, and credits do not auto-expire, so you can use them whenever you need.
If you’re close to your limit, you can either top up with an additional pack or upgrade to a higher plan. For large or growing senders, our team can set up a custom Enterprise deal with better pricing and higher API throughput. You’re always in control — no surprise auto-charges.
ListClean uses multi-step verification including syntax, DNS/MX, SMTP inbox ping, catch-all detection, and disposable/role-based filtering. Our goal is to keep your bounce rate as low as possible and protect your IP/domain reputation. Many teams switch to ListClean after seeing better results and more transparent pricing.
Speed depends on list size and mail-server responsiveness, but ListClean is optimized for high throughput. We routinely handle hundreds of thousands of emails quickly, and Enterprise customers can get dedicated resources for even faster processing.
Yes. Agencies, lead-gen companies, and service providers use ListClean to keep client lists clean and campaigns performing well. Our Enterprise options include volume discounts, optional whitelabel usage, and account management to support multi-client workflows.
Switching is simple. Export your lists from your current verification tool, upload them into ListClean, and start validating with our multi-step engine. You’ll get a clean file with clear statuses plus better pricing transparency and free Unknown results. Our team can also guide you through the migration if you’re a high-volume sender.
