What is Outbound Marketing. Difference Between Inbound & Outbound Marketing?

Hi,

I have faced 1 interview where company person ask to me outbound marketing & inbound.

Anyone please tell me what is it exactly.

Outbound marketing is the opposite of inbound marketing, where the customers find you, mostly through various paid and natural search engine marketing efforts.

The useful content pulls visitors toward your website, brings them closer to your brand, engages them and converts them into customers as well as loyal followers. In contrast, outbound marketing includes traditional approaches, such as direct mail, cold calling, radio ads, television ads, trade shows and telemarketing.
