To simplify, think of credits as internal currency. Each verification deducts one credit from your account. You can acquire credits either by purchasing them or through referrals.

In summary, yes, one successful verification will cost you just one credit. However, credits may also be used for other operations in the future.

There are two types of credits available:

1. Daily Credits: These are part of a monthly subscription and renew every day. Unused credits do not carry over. They will continue to renew at the free tier’s limit after the subscription ends.

2. Instant Credits: These never expire. You can use them anytime and keep them in your account for as long as you want.

If you have both daily and lifetime credits in your account, the daily credits will be used first. Lifetime credits are only used when daily credits are exhausted.

For instance, if you have 10,000 lifetime credits and receive 20 daily credits for free, the first 20 verifications will consume the daily credits. As long as you verify fewer than your daily limit, your lifetime credits will remain unchanged.

Absolutely not. We will never charge you for unknown email verification results. Unlike some competitors who may charge for processing results even if they are unknown, and require you to contact support for refunds, we automatically refund credits for unknown results to your account. You can easily check the refund status in the "Credits History" section.

In the event of a credits refund, lifetime credits are prioritized for refund first, regardless of the ratio. Any remaining credits will be refunded as daily credits. We are committed to valuing our customers and ensuring a transparent process.

Yes, you can. We currently accept uploading Excel files in CSV format. Our system will automatically identify the email column based on the column header and the data itself. After verification, the downloaded file will include additional columns with verification details, while your original columns will remain unchanged.

Generally, it takes about 8-12 minutes to bulk verify a set of 10,000 mixed-quality email addresses. The time may vary depending on the size and quality of your email list. Factors such as email server response times, the need for multiple checks to avoid gray listing rejections, and server load can affect the speed. If our servers experience high demand, tasks may be queued, though we typically address such issues by deploying additional servers to minimize delays.

We do not retain any uploaded data for more than 15 days. After this period, all data is automatically deleted, which means you will not be able to download verification results after 15 days. Rest assured, we do not share your uploaded data with anyone, and it remains fully secure within our protected system.

We are committed to providing the best service at the best price. To verify our claims, you can conduct the following tests to evaluate our service:

• Verify Microsoft Emails: Test our ability to verify Microsoft emails (Outlook, Hotmail, Live). Microsoft has stringent policies, and many services struggle with accurate verification.
• Verify Yahoo Emails: Check how we handle Yahoo emails. Many competitors either misidentify Yahoo as a catch-all or fail to verify them correctly.
• Test Temporary Email Addresses: Use TEMPMAIL and other top temporary email providers to see how well we detect temporary addresses compared to others.

Performing these tests will help you assess the quality of our email verification service.
