I don't think any judge would find that giving you two "pre-notices" is harassment. If he tries to evict you using these notices, they won't work. Rent must be one day late before a notice would be effective. Just ignore them.

It doesn't seem likely that a pre default notice would have any legal significance if he were to try to evict you at a later point. The notice provision of the lease provides for where any correspondence should be sent to the parties. If the landlord is not corresponding at the correct address, you should point out that fact.
