Try to control the size of your files, prefer small files; you can find several sites online that allow you to reduce the size of your file, and computers also have this functionality. It may happen that your files are larger than what is allowed, and it is difficult to lighten them, you can therefore use the temporary storage services offered by numerous sites on internet, instead of "uploading" the file in the message; within an email, a link weighs less than an attached file.

Also, for what concerns the storage, prefer, when possible, to favor local storage of documents, videos, images, rather than cloud storage, both from computers and smartphones. Still remaining in the email sector, among our online habits that can damage the environment we also find storage space: periodically clean up your storage spaces from emails that are no longer important, also because this will prevent you from receiving and sending emails when the archive will be full; many users have the impression that the internet has no limits, but it does, so try to keep your profiles as light as possible.

Finishing with emails, try to send emails that contain more information and will therefore require you to send a single email; don't send hundreds of emails each of which contains just one piece of information and try to limit short replies.
