Velocity Marketing Software has a built in Spam Assassin that does free Email marketing analysis. Spam assassin looks over your Email and rates it on a score to detail the probability that it will be marked as spam. Spam assassin checks your header and the body of your Email to make sure that it is not mistakenly marked as spam.

You can also track the progress of your marketing Emails. You will be able to see when someone subscribes to your Emails or opts-out from receiving any more. This will keep you from sending unwanted Emails in the future. Email marketing analysis also allows you to track how well your campaign is operating. Because of this, you will be able to fine tune your campaign to better suit the needs and wants of potential clients.
