How do I delete old emails

In the search bar, you can type the date in a YYYY/DD/MM format to filter out emails before a certain date. If you type before:2014/01/1, you'll see a list of all of the emails you received prior to Jan. 1, 2014.
You can also search by how old emails are. If you type older_than:1y, you'll receive emails older than 1 year. You can use m for months or d for days, as well.
If you want to delete them all, click the Check all box, then click "Select all conversations that match this search," followed by the Delete button.

Try Mfg website and or email their customer service with serial number.

Try manualslib.com or MFG website, or email their customer service.

What kind of email do you use (yahoo, gmail, outlook, live, etc)? Usually you would click on the Date column header to order by date. Click it again, and it will reverse the order.

Go down and tick all the boxes to the left of the email that you'd like to delete. If you want to delete more than one email, click the box next to each message that you want to delete.
Above your mailbox, click the Delete button (the trash can icon).
You can delete 'All' but that might be too drastic

Option one: Go into your archive, press the select all button, and hit delete. This will probably remove only one page at a time.

Option two: Make a new filter for emails sent/recieved before a certain date (today or however old the emails are supposed to be) and choose to apply them to existing conversations. Choose to have all emails in this filter deleted immediately.

Note: If there are any emails you want to save, put them in a special folder and/or star them first and then make sure the filter/select all button marks only unstarred messages.

yes.. if you still remember your email and password
