how to send large files via email

When you need to send a large file via email, it can be frustrating when you get a pop-up that tells you your files are too large. Surprisingly, most email servers cannot send or receive files over a specific size.

Not only that, just because you can send an attachment through the sender’s email server, it does not necessarily mean that the recipient’s email can accept it. How do you ensure you send an email attachment that your recipient can open? Read on to find out how to send large files via email.

You need to ensure you know the size of your email attachments before you send them. Size limitations for email servers are not one size fits all and vary for each provider. Luckily, most email services will display the file size next to the file name.

If you are attaching multiple files, you will want to keep track of your attachments’ total size. If the file size shows in Kilobytes instead of megabytes, know that there are 1024 kilobytes in one megabyte.

Many businesses and individuals alike are using cloud-based service providers and cloud-based file transfer services to bypass attachment size when sending large files over email.

When you have large files to send over an email, but the file is too large, one of the more efficient solutions is to use cloud-based storage services.

Cloud storage spaces like iCloud Mail Drop, OneDrive, and Google Drive are excellent ways to send large files through email. When you have high-quality graphics, videos, presentations, data, or more, you need to send it over, cloud solutions allow you to upload your files to the cloud service.

Then send over the link for your recipient to access the file through a link instead of an attachment. If it sounds daunting, it’s easy once you get the hang of it. Here’s how you send large attachments through cloud-based storage services.
