  • Hi @jorihlen,

    Thanks for reaching out. The error log indicates that your account do not have Gmail API enabled. Please follow this article and enable Gmail API.

    I hope this helps!

    Thank you very much for your reply, Sanjeev.
    I already considered that option (because the FAQ).
    But the problem persists.


    Hi @jorihlen,

    When you enable the Gmail API. Could you please reconnect your Google account by clicking on ‘Allow Plugin To Send Emails..’ button and let me know the error you’re getting? Please make sure the account you’re authorizing has the mailbox and has mail send permission.


    Hi @jorihlen – We haven’t heard from you in about a week, so I’m going to go ahead and mark this ticket resolved. If you still have questions, though, please feel welcome to continue the conversation.
