FAQ
Why is checking of email validity important?

Validity of email is needed for three main reasons:


  • To minimize the Bounce Rate for bulk email campaigns;

  • To improve the sender's reputation with the postal services, and the IP-address is not blocked;

  • To save the advertising budget and the profit of the company.
    You can check email address validity using special online services or a program, the so-called email list checker. The Atomic Email Verifier Online service performs the analysis in three stages and includes the following email validation rules:

  • correct spelling of the email address (no characters are missing or there are extra ones)

  • domain check for existence and catch-all analysis,

  • revision does this email exist and excludes disposable and technical addresses. The finished report can be obtained in the web version and downloaded on a PC.
Can checking email addresses online for free clean the database efficiently?
You can check email addresses validity online using a variety of services, each with its own characteristics, pros and cons. This can be done, but sometimes you will not be able to download the file with the results, or the check will be of poor quality. For example, a free email online verifier will help to check for email that is spelled with an error. But checking the domain for activity and existence, find out whether it is valid mail or not, is it a one-time account, technical or valid. Test many options, and select an email address verification service for your business needs.
How to check email address validity for free with a small subscriber base? Atomic Verifier Online has 100 free checking.
Often, email address validity checkers give a test period. So, you can find out how they work in practice and choose a convenient one for yourself. A fully free email validation service won't solve the problems, but it can create a new one.
What is the difference between email checking for validity and verifying?
The meaning is the same, just verification is a broader process.
Checking email validity includes analysis of the syntax, setting up MTA records, whether a domain exists or not, calculates disposable addresses and identifies corporate accounts.
Verification includes the check to see email address is valid, an additional revision for the following parameters:

  • SMTP server from the back side;

  • domains with catch-all function.

Email verify service allows you to revise more contacts due to the catch-all function. There are special domains that accept all mail with their domain mark, for example 85749769469@natwest.com. There is no such address, but there is a domain prefix "@ natwest.com" due to which the server accepts notifications, but they do not go anywhere further. Online email address verifier can cope even with this.
