I'm receiving emails and I'm seeing messages on some websites that say something like 'Posted from my [smartphone]'.

I don't have a smartphone (yet), so I don't know if the message configuration is opt-in or whether it has an opt-out.

Do you have any experience with this type of message, can it easily be removed? Is the opt-out explicit?

Pd: 'Posted from my five year old laptop'

  • @Patrick, I think it's a usability issue as I wouldn't want to talk down to others from my 10.000USD price tagged smartphone.

As someone who has never owned anything less than a smartphone, I can say this with certainty: every (major) smartphone operating system/mail application allows you to opt-out of the "Sent from my [device]" suffix that is the factory default. It's typically part of the mail signature, which is entirely configurable.

    You might also note that a very large portion of users never edit their settings either, and a slightly smaller group don't know that such settings can be changed. Even if people don't like it, the default behavior is sure to live on.

As someone who communicates with smartphone owners, I find it helpful when I see "sent from iphone" as a signature. It helps explain the brevity of the message, that is, we will often write a shorter message via phone than what we do through a pc/mac keyboard.

    That's an interesting point of view. I never thought of it like that. +1

You can remove it in the settings. I think by default they add it, but it's pretty simple to remove, from the iPhone at least. I'm sure you could with the others as well.
