Ever wondered what elements comprise the so-termed 'perfect' marketing mix? Well here's the list you wanted:

Direct Mail
Internet Marketing
Email Marketing
Advertising
Telephone Marketing
Direct Sales
Strategic Alliances
Up-selling existing customers/clients
Referral Systems
PR

Most people choose 1 or 2 as their predominant focus with another 2-3 as their back-up. That's ok, but if you really want to increase your profits why not add a couple more to the mix. It doesn't need to be too many if you feel you're not confident with marketing per se. It also doesn't need to be terribly expensive. There are loads of ways to get coverage without spending a million dollars.
