Do we really have good email addresses?
Here are the proofs:

Our email lists are good, because:

We know how to verify the email addresses of various domains.

It is really possible to verify the email lists of various domains (hotmail, yahoo, aol, gmail, etc.). However, one must know many nuances. Actually, not all programs are suitable for proper verification of email addresses. Some of them are only able to verify, whether there are incorrect symbols. What is more, some mail servers have high verification limits, thus, protecting themselves from the frequent referral. However, there are some ways to remove this obstruction :)

Now we shall demonstrate that we know how to verify the email addresses of various domains.

We have some email addresses with different domains. One address of the mentioned domain is good, and the other one is bad. We have just added some letters. Now we have some addresses, which are obviously bad even without verification, because have incorrect symbols.

Before verification (picture 01)

After verification (picture 02)

From 10 email addresses 4 are good. Bad are those, the letters were added to, the syntax is bad of another one, and one email domain does not exist at all.

If you use unsuitable program or haven’t configured the program properly, then you will obtain different results of verification of the same email addresses. See Picture 03. Currently, almost all email addresses are good, although it has just been shown, which are good and which are bad ones (picture 02). In the second picture, a good program with proper settings was used, and in the third picture - the same program with wrong settings was used.

After verification with wrong settings of the program (picture 03)

Let’s verify some more hotmail addresses. Generally, it is enough to take 1000 addresses, to check them and calculate the percent of good addresses, when checking a list. The similar percent shall remain after checking a million or more of them. The percent of good addresses can fluctuate by maximum 5 points.

1000 hotmail addresses were loaded to the program. Those email addresses are from our list.

1000 hotmail addresses were verified (picture 06)

Let’s check 1000 aol email addresses.

1000 hotmail addresses were loaded to the program. Those email addresses are from our list.

1000 aol addresses were verified (picture 09)

In my opinion, we have already proven that we know how to verify email addresses. Thus, if we know, we have the good email lists.

We can verify quickly and a lot of email addresses because we know what we do. Thus, we offer good and high-quality email lists for affordable price.
