Editor not replying to emails long time after submission
The way I see it these two scenarios are the most likely:


They feel they're being pestered by you and so are ignoring your emails. This would apply if by "many" times you mean you wrote them so many emails that they got annoyed. It's also more likely to be the case if, in your field, the average review times are up to 1 year (e.g. mathematics).
The other possibility is that the editor is busy/inactive, and isn't paying much attention to the journal. 


Your options are:


Wait and see what happens.
Write to the journal office and ask for a status update. Check the journal's website and see if they have a contact email. If they refer you back to the editor then the chances of #1 having happened increase (although it's also possible that the desk editor is simply not very motivated and is passing everything on to the editorial board).
You can also ask the editor-in-chief instead of the handling editor.
Withdraw and submit elsewhere. If you choose this route, look around at the editorial management system and see if there's a withdraw option.
