Verify Email Addresses
ListWise is a powerful email cleaning and validation tool that verifies email addresses and corrects obvious typos.
Smart Email Marketing
Reach the Inbox folder and avoid your campaign being stopped and IP being blacklisted with ListWise’s bulk email verifier tool.
Unbeatable Accuracy
99%+ email cleaning accuracy with world class algorithms and logic. We can verify every email address, regardless of the email provider.
Why ListWise?
ListWise is the world’s most accurate email validation tool and email list cleaning service. Our approach to email validation checks the email provider MX records and performs a real-time SMTP handshake to verify the validity of each individual email address. This ensures that your email lists are clean and up-to-date, which can improve your email deliverability and campaign performance.
ListWise intelligently cleans your email lists by separating the email addresses into various categories, such as clean, duplicates, and bounces. You can then download these categories in separate or combined CSV files. ListWise also identifies and removes no-reply and potential spam-trap email addresses, as well as fixing obvious typos.
In addition to our email cleaning service, ListWise also offers API integration for developers. This makes it easy to integrate ListWise with your existing email marketing platform and start cleaning your email lists right away.

Email List Cleaning Reinvented
Data Clean
Once ListWise has completed the clean, you will have a complete breakdown of the emails in your list. You can then download the valid emails in CSV format.
Send Strategically
ListWise gives you a breakdown of the numbers and percentages of free email addresses and role-based email addresses. This will allow you to develop the right strategic approach for sending to those email addresses.
Higher Inbox Rate
By ensuring you are sending to good and clean email addresses, your ISP deferrals and rejections are kept low thereby giving you consistent, long term, inbox delivery rates across all major ISPs.
No More Dead Ends
Bulk email lists contain a lot of generic and no-reply email addresses hidden among the good ones. ListWise automatically moves these dead-end email addresses to a separate list so you can still email to the generic ones if you want to.
Real-Time API
Perfect for developers, the ListWise instant real-time API will take your email cleaning experience to another level. An API like this does not exist elsewhere in the market. This API does the complete ListWise clean (including a real-time SMTP handshake with the email providers) and gives you an instant result. This API is perfect for online registration, opt-in and signup forms – that require an instant verification of a single email address.
