Hypothetically lets say I start up a... mailorder company... since the company is new would it not be news to say "hey we exist check us out!"
NO!How many kids on here have said "Me and a buddy are startinga t-shirt company".
You existing is not news.
Unless you are having a sale or something that actually exists, then I do not want or need to know about you. Mean maybe, but for a while there was a new batch of kids almost daily claiming they were starting a clothing company.
If you are just starting and want an announcement, hold a sale, and announce that.
Otherwise, you are just another fly-by-night operation.
And you better have a website, and a good domain name, not a .tk or CJB.net domain name. One you actually have to pay for (a tld domain).
If you want to be taken seriously, take your website and promotion seriously.
