I know that if you reach agreement with members that you can use email as a method for sending announcements and bills to members rather than USPS.

If you have some members that do not agree and require USPS mail can you charge them a fee for the extra expense? or the other way, give a discount to members that allow email to be used

Thanks

Hmmm - This isn't a question I've ever thought about before.  It seems the easy answer would be to calculate the total cost of mailings per year and add that to the budget so that when you calculate the share of total costs each member owes, that would be part of it.  I suppose someone could argue that that's not fair because it means those who allow correspondence by email are paying for the USPS service they do not use.  But they are likely already paying for maintenance of parts of the road they do not use.  It's similar to the argument that everyone's property taxes pay for schools, whether or not they have school aged children, because it's in everyone's interest to have an educated public.  Similarly, it's in the interest of everyone in the road association to see that all members get notice of meetings, dues owed, etc.  It's not as if a member would have to pay for USPS delivery which they do not use and then also provide an alternate delivery service at their own expense - unless the only reason they have email service is so they can get their road association notices, which is unlikely.
