Notify End Users that Lead/Request was received
I'm a service provider, not a retail shop. Our previous management systems would send an e-mail as soon as a request/lead was received by the system. This lets the customer know that they are important, their request was received, etc.
Right now, we are manually generating an e-mail, but unless we are sitting in front of a computer, it might be a few hours before the customer gets a response. In that time, they may go somewhere else because we did not acknowledge their request/lead.
You should be able to add that message in Admin > Leads Preferences!
