Fully equipped email verification solutions

Use our Listclean email verification service to detect and suppress invalid email addresses. By maintaining a clean list, you reduce bounce rates and improve your performance with mailbox providers.

Detects Spam Trap

Our List cleaning service identifies many spam traps that might exist in your lists. Removing spam traps from your list is essential to your email hygiene.

Hard Bounce

Our List cleaning service tells you which emails will bounce. To keep your hard bounce rate under control, use a list cleaning system before every blast.

Abuse Email

Our List cleaning service can identify and remove emails that have a history of marking emails as spam, thus improving the health and hygiene of your list.

Toxic Domain

Our List cleaning email verification service will remove the toxic domain from your list. Toxic domains are known for abuse, spam, and bot created emails.

Invalid Syntax

Our List cleaning service checks the syntax of the email address and removes from your list if it fails RFC syntax protocols.

Disposable Email

Our email verification tool checks and removes the temporary emails that are used to sign up to websites without giving their real email address. These emails are short-lived from 15 minutes to around 6 months.

Role-Based Email

These emails belong to a position or a group of people, like sales@ info@ and contact@. Role-based emails have a strong relationship with people reporting emails sent to them as spam and abuse.

Catch-All Email

Our list cleaning service checks for domains that are identified as catch-all domains and remove them from your list. Catch-all domains are domains which return valid for all emails.

MTA validator

Is there an email server responsible for accepting email messages? We run advanced email verification checks to validate MX records. This way, you’ll know if a certain email address is genuine or fake.

All good, how much should I pay?

Frequently Asked Questions

Need answers about ListClean's email verification? Look no further than our FAQ section.

At ListClean, we use a credit-based system for our email validation service. Each email address that you wish to validate will require one credit, regardless of whether you’re validating in real-time or in bulk. These credits act as tokens, allowing you to take advantage of our cutting-edge email validation technologies, which can help you improve your email deliverability and engagement rates.

Yes, you can upload Excel files with multiple columns in CSV format for email verification. Our system will identify the email column based on the header and data. After verification, you’ll be able to download a new file with verification details, while keeping your original columns intact.

At ListClean, we guarantee that your credits will never expire. Whether you’ve purchased credits or received them as part of a promotional campaign, you can rest assured that they’ll always be available in your account. You have complete control over when and how you use your credits, and you can use them at any time that’s convenient for you.

The speed of list processing depends on several factors such as the size of the list, the quality of the data, and the complexity of the verification process.

At Listclean, we use advanced tools and systems to ensure efficient and accurate list processing. We can verify up to 100K emails per hour per customer, but we can also increase the speed if needed for larger datasets.

We understand the importance of your data privacy and security. At ListClean, we guarantee that your data is always under your control, and we never share it with any third-party entities.

We keep your data stored in your dashboard for your convenience, but you can delete it permanently anytime you want. Our team takes every measure to ensure that all user data is secured using enterprise-level security standards, so you can trust that your data is in good hands.

ListClean will not charge you for “unknown” results. Occasionally, we encounter email addresses that cannot be verified for various reasons. In such cases, we provide an “unknown” result to indicate that the verification process was unsuccessful. While such email addresses are typically considered risky, we do not charge you for checking them.

Additionally, we do not levy any credit charges for removing duplicate email addresses from your list, so you can trust that you’re only paying for verified results.
