A plug-in "mailcheck.js" that halves the registration confirmation e-mail that does not reach the user

ByHelga Weber

There are systems that are in the flow where temporary registration mails and final confirmation mails are delivered to registered e-mail addresses after user registration and account creation, but if you mistype the e-mail address at registration and this e-mail arrives There is a person who gives up giving up as "Because it is already troublesome ...". A JavaScript library and jQuery plug-in created to reduce the situation of this "confirmed mail unreachable" which is a major pain to the service provider is "Mailcheck.js"is.

Provide an application that makes it easy to create photo albums from smartphones and PCsKicksendWe will send you a confirmation email after entering the necessary information in the account registration form. New users need to receive the mail and activate the account, but there is always a certain number of unsuccessfully delivered mails.


If the new user has not received a confirmation email, the user must register again or contact Kicksend to change the email address. Kicksend thought how to reduce the number of registered e-mails that would not arrive. When examining the pattern of the confirmation mail that returned without reaching the new user, it turned out that most of them, such as "hotmail.con", "gnail.com", "yajoo.com", etc., are misspellings of the domain of the mail address.

So Kicksend created a plug-in that automatically indicates the correct spelling when there is a misspelling in the domain "Mailcheck.js". As shown in the image below, it is possible to notice immediately the incorrect input content. Implementing this plug-in will show effects more quickly, and the amount of registered e-mails returned is reduced by 50%.
