Comparison of ValidTo with ListWise

To give you a trial run, ListWise offers 100 free credits upon signing up. You can use these free credits either through bulk upload or through its developer API. In terms of free trials and credits, ListWise comes in second after MyEmailVerifier.

In addition to detecting Gmail, Yahoo, AOL, role-based emails, disposable emails, catch-all emails, and more, Listwise is also very good at detecting email addresses. In addition to identifying and removing invalid and duplicate emails, it also detects and removes spam traps that are hidden in your email list, making your email list as clean as ever.

It offers excellent customer support through email, phone calls, and live chat. The customer service team replies to live chats within 2 to 3 minutes. In addition, the phone support team has six contact numbers located in different locations, which makes it easy for users to get their technical questions answered quickly.

Additionally, ListWise allows you to verify up to three emails daily without creating an account.

The ListWise email verification tool also fixes the obvious typos by itself, so you don't have to do it manually.

When it comes to data security, ListWise doesn't compromise anything. It is a PCI-DSS-compliant email verifier. Bulk data uploaded by users are automatically deleted after 90 days, or you can manually delete them by clicking on the “Delete List” icon given in your dashboard. Apart from that, it does not store any data cleaned using its API.

In addition to that, ListWise has a high minimum order value, which is $44 for 10K credits if you choose a monthly plan, and $45 for 10K credits if you choose a pre-paid plan. Consequently, Listwise was not able to make LCA's list of the top 10 most affordable email verifiers.

Listwise's signup process is a bit longer than other email verification services.

While most other vendors offer integration facilities with all well-known ESPs and marketing applications, Listwise does not provide integration facilities with any of them. Users will not be able to upload their email lists directly from third-party applications since there is no integration facility. They will also not be able to manage their marketing activities in one place.

In our auditing, it took 475 minutes to verify 10K emails. So, users have to wait while ListWise processes the email verification.

ListWise has less accuracy than other vendors, such as MyEmailVerifier, ZeroBounce, QuickEmailVerification, etc. However, the vendor claims 96% accuracy, and we found it 78% accurate during auditing.
