Me and my collegues have a discussion about how to minimize the problem that
people are (apparently) not able to type in their own email address
correctly. In the application we developed for a customer this turns out to
be quite an issue.
One of the possible remedies could be to ask people to type in their email
address twice, just as it is often done with passwords.
However, we wonder how effective this will actually be. This trick will not
help if people 'copy-paste' their email adress. Or worse, they might type it
wrong two times.
Another approach might be to introduce an extra confirmation screen where
the email address is displayed. Some may recognize that their email is
spelled wrong...but some may also be blind for it...
Has anybody got any experience/data on the effectiveness of asking for the
Is it worth the extra irritation?
