Suddenly many people have problems using the internet on computers or smartphones. No worries, Gmail can be used without the internet. Surprising to hear, that you can read old e-mails in Gmail without internet as well as send new e-mails. However, the new e-mail will not go to the recipient’s address immediately. E-mails sent offline will go to the specified address as soon as the internet connection is turned on on the computer or smartphone.
To use Gmail offline, first, use https://mail.google.com/mail/u/0/#settings/offline. Now you have to tick the Enable offline mail option. Here, after logging out of my Google account, you have to select any of the options below. If you select Keep offline data on my computer, even if you log out of Gmail, the information will remain on the computer. And if you select Remove offline data from my computer, then the work done offline will be deleted when you log out of Gmail.
