Hotmail, Yahoo, Gmail Attachment Size Limit
Email has allowed us to send files & documents online without any fees & it can reached the recipient in just a few seconds time. However there’s a drawback : Email service providers such as Hotmail, Yahoo and Gmail have attachment size limit for the files being attached.
So what are the attachment size limit?
Hotmail : 10MB
Yahoo : 20MB
Gmail : 20MB
So now you know which email service provider that you should choose 
If you are finding an alternative to send big size files, try service such as yousendit.com which allows users to send files up to 2GB!
Humm..well u can use Humyo (www.humyo.com) to upload and share files online. You will be given 30GB for you to upload all of your files online: access frm any pc, share ‘em wiz every1 who has an email add and also publish multimedia files on your web page.
I think your information is wrong, I have recently tried to send emails to Hotmail addresses that are 5.1MB
It fails with the following delivery report:
“Delivery to the following recipient failed permanently:
**********@hotmail.com
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 552 552 Session size exceeds fixed maximum session size (state 18).”
@Rob : Maybe the recipient’s inbox is full with documents, that’s y your attachment couldnt reach him/her
Even considering a file as much as 20MB may be sent out of gmails, Google annotates that allowance with a caveat that attachments are sent with added encodings for the trasmissions of the email. So a document of exactly 20MB may fail delivery because with transmission encodings added to the document vy itself, comes to exceed the size allowance in Google and most certainly in other servers as well. Additionally, Google reminds its users, as I am, that senders should consider the size limit the recipient’s server allows, such that the recipient’s email has the capacity to receive a large file. If incompatibility exists, I have found out in my own experience, that the email fails delivery, which is why I have been looking at the attachments size limits of various servers, other than Google. Thank you for posting hotmail and yahoo attachment limits. There are also those now rarities but persisting: aol.com, university department addresses, sbc.global,net, cox.net and many more among my contacts that reject large file attachments.
i think the size limit for gmail is about 25 mb, cuz i sent 9 pics 2 a friend once, and they were all between 1.5 mb – 3mb
thank you for a grat website
