Write a BD email format for PCB buyers with killer subject and responsive CTA .

Hi, We need a BD email for new customers in printed circuit board (PCB)industry. We are a manufacture of single/ double layers PCB, experts for quick turn around(also known as QTA) prototype=small qty manufacture. Our customers are design houses(brokers) and electronic engineers (end customers) or even procurement of EMS/CEM= electronic manufactures Of course we have lots of competitors both home and abroad, too. We may not offer the lowest price nor the quickest delivery, but we can offer next to lowest cost, with service second to none. Local vendor( next door/ country) is preferred if our customers are in extremely hurry ( needs his product 12-48hrs). Otherwise, we can offer same quality product at 1/3 of his budget. Compared with other local competitors, we are true factory instead of an agent. We don't add on any delivery charges( like DHL quoted 10, but charge customer 50). And our quality+service is top of the class. Pls check the attachment for our special offers . Some other vendors may do the same, but only we can do it at our own factory house with quality 100% guaranteed. Looking fwd to working with you, pls help us with your killer subject and CTA content. Pls reply me with your rephrase of this attachment or how you would draw customers attention with killer subject. Thanks!
