All email systems limit the size of your attachments, which is why you need a good strategy for sharing large files with others. It's best not to use a process that requires the recipient to jump through a bunch of hoops or sign up for a service they don't already have. Dropbox users that also depend on Gmail should look into a great little add-on that integrates the two services. Once installed, it makes it really simple to share items you already have in your Dropbox account with anyone, even if they don't use Dropbox. This can save you lots of time because you don't need to upload the file to another online file-sharing website. This can come in really handy when you have a large number of files to share, which eliminates the need to send separate email messages or use a Zip utility that the user has to unzip. The utility does a lot of cool things, so if you use both services and haven't gotten the extension yet, check it out at: https://bit.ly/38aInGD
