Newsletters, promotional offers, various content: all contribute to maximizing the visibility and performance of the brand. At least as long as they are sent to the right addresses (valid and active). If necessary, with incorrect addresses, the brand can be penalized, both in its image and reputation and on its sales.

What is the validation of the email?

It very often happens that an email address entered is incorrect, that it contains errors (typing or spelling mistakes, for example). This can be deliberate or involuntary on the part of the person who informed it. It only takes one letter less or more, a symbol in poor place, so that the address is no longer good and therefore turns out to be unusable.

This is where the email validation process comes in. Indeed, the latter will be able to identify typographical strikes or typographical errors, whether deliberate or not. It will also allow, when the address is tapped, to quickly confirm that the address exists well with the entered field (Hotmail, Gmail, Yahoo, etc.).


Validation helps to significantly reduce human errors when entering email addresses, such as in form fields. It is essential for the organization and cleaning of the distribution lists, and helps the company keep a good sender.

What is an email verification?

The verification process is an essential step which aims to verify that the email is sent to a real recipient. It therefore makes it possible to ensure that the account of the reception box at the end of the chain exists (validity), that it is well-used therefore active, and that it accepts incoming emails. Once this process is finished, you know that your email will reach the right person.

The verification concerns the syntax of the email address, but also the validity of the domain, the “catch-all” accounts, and the MX records.


Verification allows the company to prevent hardbounces, to ensure that Its recipients receive the emails intended for them correctly and at the right time. It is therefore a saving of time and money in the sense that this process avoids sending messages to inactive or erroneous addresses. It also allows the company not to see its communications considered to be spam. It also intervenes in terms of campaign results, because it can be perfectly constructed and effective, but not to work, simply because many addresses in the list are unusable.

Overall, the verification of emails is a major asset for guarantee a good delivery rate and keep a good reputation as a sender.
