If they were interested in purchasing your house, you would have heard from them by now. When such solicitations arrive, they are put aside for review by members of the procurement committee. If they see value in the property, it will be discussed with the members.
They probably will treat your email the same as they treat any other property for sale solicitation.
Do you know the name of anyone in the club? Can you find out? You could try hand delivering a copy of your offer and photos. You could also ask for some feedback as to what types of properties the club is interested in, to give you an idea about the level of interest the club may have in your property.
How investment clubs work vary with the club. But as the others said, I am certain they are solicitied all the time.
If it was an excellent price, you probably would have heard from a member(s) of the club by now.
Many real estate investor clubs have sub-group meetings, often in local eateries. Get flyers printed and go to these meetings and pitch your property to them. If the club has a monthly meeting, see if you can go there and pitch it also. The size of of investment club may be of importance here.
Are you a member of the club? Usually, members can showcase their properties during their monthly meetings.
Another thing is to list your property on their online forum or classified section if they have one.
