How to send a large file by email

Are you looking to transfer a large file by email but not sure of the best way to go about it? We get it – there can be a lot of confusion about attachment size limits and free file-sharing services. So makes it easy for you, with generous attachment sizes and a file-sharing function integrated into our Cloud. Here we explain the three best options for sharing large files.

What is the best way to share a large file?

 Depending on how large the file actually is, consider one of these three options:
  1. Send the file as a regular email attachment
  2. Compress the file by saving it in a zip format or folder
  3. Use an online file-sharing service
Let’s take a deep dive into each of these options!

Sending a large email attachment sets an attachment size limit of 30 MB for our free email accounts – larger than almost any other free email service – and a whopping 100 MB for our Premium customers. If your attachment size falls within these limits, you can simply attach it as usual in your Compose E-mail window by clicking the paperclip symbol on the top menu bar or in the lower left corner and then selecting the file(s) from your computer hard drive or the Cloud:

You can send several attachments with one message; the attachment size limit is measured in terms of the total size of the attachments to a single email. So if you want to send two 20 MB attachments using your free account, you’ll have to attach them to separate messages – or consider the options below.

Compressing email attachments to make them smaller

If you want to send a huge file (or lots of small files that add up to more than your attachment limit), there is a way to make it smaller. This is called “compressing” the file, although it’s also referred to as “zipping” because of the name of the most common tool used for this process. Compressing a file can make it roughly 50 to 90 percent smaller, depending on the file type. Several files can also be placed together in a single compressed folder. It is very easy to compress a file, and the process is similar on most computers: You simply right click your file(s) and select the relevant command, which will be something along the lines of Compress, Zip, or Send to zip folder. This will create a new file of the same name with a .zip extension, which you can now attach to your email exactly as described above.

Sharing a file online

Attaching your file may not always be the right option: even after compression it may exceed your limit, or your recipient may have a more restrictive email limit or data plan that makes it hard for them to receive big attachments. In this case, a secure online file-sharing service is your best option. customers can take advantage of our free Cloud to share files right from their inbox. This works by creating a link that you send to your recipient letting them download your file. This is an extremely secure process, and it’s even possible to set a password for opening the link. Simply upload the file in question to your Cloud. Then select the file and click Share to create a guest link:

Now you can either copy the link and paste it manually into an email or text message for your recipient, or click Send a link via email to automatically create an email containing your link. If you’d like to password-protect the link, first click Share configuration to set the password, which you can then share separately with your recipient.
