Your web site is just one avenue of telling people who you are and what you offer. You may have a number of email addresses of contacts and business leads which can represent an opportunity to remind people about you as well as special offers you provide. You can of course simply send a text only email to all of these people but this is hardly eye catching.
JBH Consulting are able to help you sending business to business emails that are attractive to read. Such an email campaign can be monitored for its effectiveness to help you become more specific with future emails you may care to send. This activity is often known as Digital Marketing.
