Off-shore cold calling is the practice of cold call SDRs making unsolicited phone calls to potential customers in an attempt to sell them a product or service. These cold calls are typically made by salespeople who are based in another country, often in call centers. The main advantage of off-shore cold calling is that it can be much cheaper than making calls from within the same country. This is because labor costs are usually lower in countries where call centers are located. Additionally, many companies find that they can more easily find salespeople who are fluent in English and willing to work for lower wages in these countries.
