When you save too many emails, it can be hard to organize everything, and it can get confusing. For example, yesterday I accidentally replied to an email from an old email thread.
Another thing that could happen is you can run out of storage. The quicker you lose storage depends on which email service you use. Gmail, an email service from Google, offers 10 GB of free storage. If you run out, you can pay for more storage, but unless you’re a business, I think that can be expensive.
One of the most important reasons why you shouldn’t wait for your emails to pile up in your inbox is because eventually someday you’re storage will fill up and unless you pay or create a new email account, you’re going to have to delete all those emails. This can take lots of work if you want to make sure you don’t delete any important emails. So unless you’re going to delete all your emails at once, I suggest you should start deleting those emails the moment you don’t need them anymore. If you do this, you wouldn’t have to be like me, wasting your time and going through 2,152 emails individually and deciding which to delete one by one.
