We are an managed email marketing company based out of Indianapolis.
Currently we are working on creating new content and inbound links to the website, we run a small number of display ads for testing purposes and a few search engine ads. We also have our site in the bottom of the emails so if a subscriber for one of our clients is interested in our services they can easily reach us.
A breakdown is around 32% comes from search engines, 10% from referrals, 28% from direct traffic (sales reps lead people directly to the site) and then the last 30% coming from clicks in the footer of the mailers.
We are going to start promoting our Facebook and Twitter pages in the coming months after we get a plan in motion for providing frequent updates to our blog with helpful information for our clients and prospective clients.
