No. The judge will need undeniable proof that the landlord (not someone else) sent the notice, so the notice needs to be personally delivered or sent via certified mail, as covered in the how-to section above. Even if the landlord wants to use email as a secondary method of notice, using email should be avoided. This is because the landlord needs to maintain a professional appearance at all times, and sending a notice via email is unofficial and doesn’t convey the importance of the situation like an official letter does.
