How long to wait for a follow up email regarding domain for sale notice?

[Damion]

Hi guys,

I've recently send out some emails to notify a domain(s) are for sale.
No respons whatsoever so far.

My question is how long should i wait to do a follow up?
I have no idea if they are interested or not, at all, or if they are in the middle of discussing the proposal.

What kind of follow up would i use?
Examples would be nice

Hi Damion.

I would follow up in approx. 1-2 weeks by email.

Imho is it not good to swamp them with emails and notices.

Give them time to respond.

Hope that helps.

Thanks -fp-
In that case i'll put the brakes on

How would i compose the follow up email?
Any suggestions for subject line and body?
