Hello and welcome to Just Answer! i am Aitizaz and i will be happy to assist you today
did you check the TRASH folder of your gmail email account?
I am sorry to hear about your problem. When the emails have also been deleted from the Trash folder, the only method to recover the lost emails is to contact gmail. They might bring you back the deleted emails through their server.
In order to ask them to recover the emails for you, you need to visit the following link and provide the required information to proceed further in the matter. The link is:
Please let me know if you need any further information in this regard.
Did you use this form to bring them back to which i have just referred you?
I understand your position and your sentiments. This can happen with any person. The only source that can recover these emails for you ( after they have been deleted from Trash as well) is gmail itself. You need to contact them again through the form i told you earlier in my messages and insist for recovery for emails. I know you do not want to hear this but unfortunately, there is no other mechanism available to recover these emails. So you must contact gmail as early as possible for recovery. i would have loved to recover them for you had there been any option available. hope you understand.
in future, do you email clients like Microsoft Outlook. they give you an option, sometimes, to recover these emails through your own hard disk as they save some content on hard disk as well.
anything else i can do for you?
