One more quick question. Are you acting as an individual i.e. freelancer, or agency? I don't think an agency would mind paying $12/month if they had a few hundred domains, so perhaps the domain limits are off and it would be better like this:
Professional - $5/month - 100 domains
Agency - $12/month - 500 domains
Max - $30/month - 2000 domains (can't see much demand for this plan)
I agree the free plan doesn't seem to make much sense. A better option would be to give a free trial period on the paid plans e.g. 7 days.
Plans feels more suitable now. Getting rid of the free account feels the right move. If anyone is interested they should be willing to 'gamble' $5. I can't see many free -> paid upgrades happening so it is probably easiest to cut it out (less support, coding etc).
If you click on signup there is a form to get a one time email when Flaregun launches (it is currently in development).
