Are We Better Than Our Competitors?

You do not need to take our word for this. You can find out this by doing some simple tests. A random test can give you some idea, but to identify the best email verifier, you should test the most difficult email addresses in a proper way. Here are some testing guides for you so you can do the testing and find how everyone performs in difficult conditions without wasting any time:

  • Try verifying Microsoft’s emails (i.e., Outlook, Hotmail, Live). Microsoft has a very strict policy. Most of the companies cannot verify them properly. So, they respond “unknown” most of the time.
  • Try verifying Yahoo emails. Most of the other companies either cannot verify them or declare yahoo as a catch-all. However, we can accurately verify the Yahoo emails.
  • Try verifying some temporary email addresses from TEMPMAIL and some other top temporary email providers. Check how many of them can detect them and compete with us.
  • Check if other companies provide instant and automatic refunds for the “unknown” results.

We always try to provide the best API & bulk email verification service, at the best price possible. If you can properly do the tests we mentioned above, we believe you will not have any confusion about the quality of our email verification service.

Top FAQ’s

What does the credits mean?

To make it simple, you can consider the credits as an internal currency. When you perform a verification, the credits will be taken from your account. One successful email verification will cost you one credit only. You can get credits by purchasing or by referring friends (coming soon).

Does one credit equals one email verification?

In short, the answer is yes. One successful verification will cost you one credit only. However, credits can be used in some other operations in the future.

Will the credit expire, if I do not use them?

There are two types o credits available. The daily credits with a monthly subscription and the instant/lifetime credits.

The daily credits renew every day (the unused credits will not add up). It will keep renewing until the end of your subscription. After the subscription ends, it will keep renewing at the free tier’s limit.

On the other hand, instant credits will never expire. You can use them anytime you want and keep them in your account as long as you want.

If I have both type of credits, which one will be used first?

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

For example, you have 10,000 lifetime credits and you get 20 credits every day for free. In that case, the first 20 verifications will consume daily credits. So, if you verify less than your daily limit, your lifetime credits will not reduce at all.

Do you charge credits for "unknown" results?

Never. We will never charge you a single credit for unknown email verification results. Most of our competitors charge for processing results even if they are unknown. Some of them claim to refund the unknown credits, but the customer needs to contact their support every time. We are very clear in this case. Credits will automatically get refunded to your account as soon the verification completes. You can also find the refund status in the “Credits History” section.

in case of credits refund, the lifetime credits will be refunded first on a priority basis (no matter the ratio), then the remaining credits will be refunded as daily credits. We value our customers.

Can I upload an excel file with multiple columns?

Yes, you can. Currently, we accept uploading excel files in CSV format. Our system will identify the email column based on the column header and the data itself. After the verification, the download file will have some extra columns created with verification details. Your original columns will remain the same.

How long it can take to verify 50,000 email addresses?

Generally, it can take around 10-20 minutes to bulk verify a set of 50,000 mixed-quality email addresses. The average time will increase or decrease based on the size of your email set. The verification speed also depends on the quality of email addresses. Some email servers do not respond as fast as others. Some email addresses require multiple checking to avoid gray listing rejections. Also if our server got overloaded by the large verification tasks from different users at the same time, your task can get queued and can take a little longer (however this is a rare case as we deploy new servers if we detect such overload issue).

What will happen to my uploaded data?

We do not store any uploaded data for more than 30 days. All the uploaded data will automatically get deleted after 30 days. And that’s the reason, you will not be able to download any verification results after that period. We never share any of your your uploaded data with anyone. Your uploaded data is fully secured within our protected system.

How can I test if your service is better than others?

We always try to provide the best service possible, at the best price possible. You do not need to trust our words in that case. You can test it yourself. Here are some testing guides for you so you can do the testing in a proper way and find how everyone performs in the difficult conditions:

  1. Try verifying Microsoft’s emails (i.e. Outlook, Hotmail, Live). Microsoft has a very strict policy. So most of the companies cannot verify them properly.
  2. Try verifying Yahoo emails. Most of the other companies either cannot verify them, or declare yahoo as a catch-all. However, we can accurately verify the Yahoo emails.
  3. Try verifying some temporary email addresses from TEMPMAIL and from some other top temporary email providers. Check how many of them can detect them and compete with us.

If you can properly do the tests we mentioned above, we believe you will not have any confusion about the quality of our email verification service.

Can you suggest anything to get a list of email addresses (leads)?

Yes, you can try our Reoon YellowPages Scraper. Yellow page is one of the largest sources of local business contacts. With our software, you can extract thousands of local business information (including email and phone numbers) within minutes.
