How to Send Large Email Attachments

May 12, 2011, By Christian Cawley

One of the great things about the Internet is how easy it has become to share information. This might be statistical data displayed in web pages, audio content downloaded from a file sharing network or a simple document sent by email.

As a rule, we use these mediums to share data appropriate to the means of communicating it. For instance, you probably wouldn’t send an album’s worth of MP3 tracks via email, not least because the recipient probably wouldn’t receive it. (The recipient might also be unhappy to find that so much data is holding up the receipt of other email messages!)

In general, a 10 MB limit is imposed by email servers preventing the sending of large attachments. This is done not to cause problems to anyone sending and receiving messages, but to protect the integrity of the email service for other users.

How to send large email attachments

However if you have data that you wish to share and email is the only way to do so, there are third party systems you can use…

Should I Email Large Files?

If you have files totalling just under 10 MB you should probably use a compression utility such as WinZip or WinRAR to reduce the final size of the email attachments. If you don’t do this, with the attachments, the email body text and the data header all added together, you might find that an attachment that you thought was under 10 MB creates an email that is greater than that limit.

You might be interested to learn that although limits are put in place by web-based email solutions, these can be larger than the usual 10 MB limit of ISPs and corporations. Therefore, one way to get around the 10 MB email attachment limit is to send your bulk data from a Gmail account, which has a 25 MB limit, or a Yahoo! Mail account which has a 20 MB limit.

If you do use either of these methods, bear in mind that you also need to consider any email attachment limits imposed by your recipient’s mail server…

Getting Around the Email Limit

If you’re keen to still send your attachment and it totals greater than 10 MB (or higher if using a web-based service as above) you might opt instead for one of the various “large storage” solutions that can be found online.

The first one you should be looking at is, which allows the sending of files up to 100 MB via their website or using a downloadable desktop utility.

You should also consider, which will allow you to split an attachment up into manageable chunks. This solution is best used in conjunction with YouSendIt in the event of your attachment being greater than 100 MB.

Other options for sharing large files include taking advantage of the popular online storage service, and similar services.
