What is your follow-up strategy once you get the leads from cold call?

I usually convert "cold' responses to "partner" -response: i.e. the customer/client never remain cold with the company. That is how successful marketing work. It is what we call today "Permission Marketing"

A customer is always analyzing whether to purchase or not with all jinds of imaginary reasons. You can successfully make him fall for your product or service if you UNDERSTAND his basic need with your product or service in question.

There is another one on marketing posted by me called 21step for marketing. You can find it in my profile. For what you asked the first link probably answers about lead generation and afterwards.

The customers are the king and one has to dance according to their tune. So it would be my pleasure to attend the call immediately. I will ensure that their requirements are met based on the meeting and discussion. To cater certain requirements will take some time and which will be informed to them. Here the customer would be delighted and this would facilitate next calls for their requirements. Sales is art of persuation. 

It may please be noted that a sales or marketing man should be able to sell himself first, then only he will be able to sell or market his products. Decent behaviour and capaity to listen them are very important. One should ensure that cutomers should not be cricised during the course of meeting, besides one should convey the intention is to serve them at all times.

Naturally all the above will involve frequent interaction and follow-up and this perseverance will lead to success in getting business from the customers. The frequent visit of customers and interaction will make them to remember.

My strategy is to persist until I succeed 

The secret of doing business lies in what you do after you generate a qualified lead.The steps we take next to build a relationship and help our prospect get what they want make all the difference. 80% of potential sales are lost due to lack of follow-up. This is one of biggest mistakes people make in marketing their business. We need to act immediately once we got a lead. People are prone to procrastinate, even when they want and need the product or service we provide. We should give special attention to prospects that demonstrate an interest. The stronger your relationship with your prospects, the more likely they'll be to turn to you when they are ready to make a purchase.
