e-mail field -> uddeim

You mean in regards of "user experience"?

You send just a notification without including the message text, and the user have to visit the site to read the message... right? Why not. Common and good practice.

On the other hand, there are always people that have complaints. Some like, some do not. You could test both configurations for a fixed time period, and compare the site statistics/visits/logins.

I think for success you have to make everything for user convenience. This is the only way to win customers loyalty. user will go to your site sooner or later. At least to write message back.

even if you redirect person to red message then what? You get another hit in your statistic? But that does not tell anything. In fact it even dissolves true statistics. You do тещ know how many true hits of users who really wanted to be o your site you have. Because you have all those hist that user did because you forced them. So the picture become blurry and you even may deceive yourself by the increasing hots number that your site is doing well when as fact you may loos real points.

A visit is always a visit, not directly associated to functionality itself but when someone comes to ur site, it's nice, even if he closes 10 seconds later. You deliver content you want to be seen, that 10 second visit is enogh for the visitor to press on an ad, or check new features.

Uddeim inbox with modules with latest content may allow the user to answer and at the same time may press on record links.

Although i don't think it's that pratical because:

1 - Uddeim i believe it does not work as e-mail client, the user to answer, has to copy it's content to his e-mail client and reply.

2 - On a public website, for people to submit the contact form they would have to be registered since uddeim sends the reply to their uddeim inbox.
