[Challenges in Acquiring Clients Despite Competitive Pricing]

Greetings, despite my efforts to set competitive prices and promote my services, I have been unable to acquire many clients. Can someone provide an explanation for this phenomenon?

[Should I contact people that had ordered from me before?]

Hello Sellers!

I am a new seller and I am trying to grow. I have been thinking on using the "Contacts"  in the "Growth & Marketing" tab to contact customer if they need any new services. Is this a good idea or not? If it is not a good idea what else can I do to start getting more orders and overall more customers to work with me?
