Is it weird to send an email 1 year in advance to let people know you are having a destination wedding ?

I did this and think it is a good idea as it give people time to think/ prepare for it.

However some people didn’t reply to say they are even thinking about it and it hurts my feelings.

I know it is far away but still I think it would be polite if they could even say ” I’ll think about it”

Any yes they did receive the email and some of them are close family.

I just think it would be courteous to even say “will think about it”

What do you think?
