<human>:  I'm having trouble with my Gmail and I can't send emails. Can you help me troubleshoot the issue?
<bot>: First of all, please try to double-check the account settings in your gmail account. Make sure that the ‘accounts and import’ as well as ‘security’ tab has been correctly filled in. 2 Then, if the account settings are fine, please try to clear the cache from your browser and then re-login to Gmail to see if the issue is resolved. 3 If the problem still persists, you can try using a different browser to see if the issue is related to a specific browser or not. 4 Lastly, please ensure that your device meets the minimum system requirements for a successful access to GMail.
