Some people will not put their email address on cards that are passed out for a trade show, but if they really want to have you contact these individuals, they do.
Contacting via email is so common place today. It is instant contact and fast deletion. The information flows faster than ever when you have an email address. Our company works with a number of clients that exchange their information using email. They send images, have provider meetings, and even develop training materials almost everywhere in email. There is little need for face to face; the use of contact overcomes long distances.
I keep in constant touch with my children who live some sort of 16 hour drive gone. I basically talk to your potential customers everyday using chat computer software and sending emails. I still call them on the phone, but email is so fast, we can leave notes every other and respond in the future. The cost is so small as well. Businesses cannot survive and do well if they do not have email to technique orders, send information and get it there on your timely basis.
For example, you will send most article writing today via email. You even have a shorter period of time in which to collect attention of editors. Some papers, however, still want to have faxes. Email also includes its problems. If you sign up for some newsletters, you can become on mailing lists to get spam mail. I only sign up for companies that say they won't sell the list. I actually use a separate email for newsletters in order to keep my personal email system fairly clean from spam. If you have your special domain (web address), I would suggest you do the exact. Use one address for signing up and the other meant for conducting business.
All of your web information like email address really should be on your printed materials. It is a way that prospects can feel comfortable speaking to you. Email is actually alot more comfortable than picking in the phone and calling. Sometimes you will send an email and then need to follow up which includes a phone call. You would do this if you are sending out a website article.
