I am pretty good at marketing. I have studied it a bit, and learned a lot about marketing on the job. I don't expect everyone to be good at it, BUT I would expect those who make a living by being accessible to the public, to figure out how to remain accessible to the public.
It never ceases to amaze me how many people I know that rely on phones to make a living, yet often change their phone number...or continuously change their email addresses. I try to refer work to people, or to call people to cover dates for me, and find the numbers disconnected, change or just not answered.
I got a message from someone not long ago, and when I returned the call, it said the mailbox was full...sent a message to a social site that was not read because they called me back because I did not call THEM back, LOL!!
When I needed to go to NY on the spur of the moment last year, I was amazed at how hard it was to contact people who do what I do for a living...no website, invalid email and changed phone numbers.
On the other side of that equation, being too complicated...an email or website that is too difficult to remember, or putting 3 phone numbers on your vehicle...pick one and forward it!!
I have been in the biz for 13 years and have never changed my email, or phone number! Sometimes, it is that simple. Just sayin'.
Out of sight...out of mind. Don't let your inaccessibility be the reason you do not succeed.
