Whoever told you that was absolutely correct. When I ran a sailing charter business I advertised my phone number online on my own web page and in various Yellow Pages type directories. I got all kinds of phone calls. In addition to legitimate calls from customers, I got lots of semi-legitimate calls from people trying to sell me stuff (for example, promo give-away items like pens with my business name on them), plus all the bogus scammers and robocallers. You have to answer every call because you never know whether a call is a legitimate customer or a bogus caller. I put up with it when I ran the business, but when I closed the business I had to change my phone number because the calls wouldn't stop.John Stone wrote: I have been told by an experienced local sailing instructor that if I adversities my business local to this area my phone won’t stop ringing. I have not done anything yet as as I remain focused on preparing my own boat ready for sailing.
The same thing will happen if you advertise an email address online--spam, spam, spam, spam... It's why you never want to post your email address in a forum like this and should always use the private message option to pass that kind of information along.
Nowadays, since I'm not in business, I have an app on my cellphone that only lets the phone ring if the caller is in my contact list. Every other call goes directly to voicemail. My phone is blissfully quiet and only rings when it is someone I actually want to talk to. Just like the good old days when we had phones mounted on the wall in our houses.
It's something to consider.
Smooth sailing,
Jim
