What is the average maximum file size (by default) for incoming email on the Android? I am trying to send an email marketing campaign and my email file size is 32K (HTML markup only).

When I open it in the native email client on my Android device (Sprint HTC running Gingerbread 2.3.5) it gets truncated with a message that says "Download Remaining 12K". The button is way below the fold so it's easily missed and 1/2 of my email doesn't even show up in the reader.

I found a setting in my (POP) email account under: 

menu → more → settings → Send &amp; Receive → Mail size limit


But the default was set to 25K. That seems EXTREMELY low. I assume this is to keep the total downloads to a minimum since most people don't clean out their inboxes very often.

However, is this the new standard? That emails need to be kept at a minimum of 25K? I am wondering how many other devices running the Android OS are configured this way by default and if I should re-think all of my email marketing campaigns moving forward.

I checked my Kindle Fire and I don't see an option to change the incoming file size and my email does not get truncated on that device.

I am hoping to learn:


Is this an Android version specific? (ie Gingerbread)
Is this a configuration one makes when setting up a device with the Android OS regardless of the version? Meaning every device is different?
How many devices are set with a max file size this low, what's the standard setting out of the box?
Is this an Android version specific? (ie Gingerbread)

No, this has nothing to do with the Android version, I have several close to me and none have such option. It's probably a carrier-specific setting on the stock app.
bahamat answer easily justifies the reason as to why carriers would prefer such low limitations and how this benefits users.

It may vary depending on the device and carrier, but what usual happens with settings like this is that they are silently applied, but as you've found out, the user can update the value to a more desired one.

There's no standard about the size for an email that goes this low. What actually exists is a general conception regarding the emails maximum size that accounts for the sum of the message's body and the encoded attachment.
Since a message will often pass through several mail transfer agents to reach the recipient, and since most of them have to cache messages for a certain period of time, this brings storage issues that need to be addressed. Since the early days, 10Mb was considered to be more than acceptable for an email.
