We're looking to start an email marketing campaign
If you are starting from scratch then you should select a platform to do the mailout.
I'd recommend Mailchimp.com - it is PAYG or subscription.
, ideally would like to use a professional or company do this for us!
You will need a professional designer who is competent at coding newsletters - inline CSS, not using images for everything so people without can see the copy etc.
However, the brief needs to be spot on at your end.
You need to know what you want to achieve and the way in which you are going to do it.
It isn't enough to just send out a brochure type email. There needs to be a compelling subject line to persuade people to open the email, and a persuasive call to action to get people to click on a link.
We will be targeting existing customers and also trying to find new customers.
Targeting existing customers is the easy bit - but how do you plan to recruit new ones through the email?
Is there going to be a viral element - getting existing customers to forward it on to contacts or friends? Why would they do that? What's the benefit?
If you want to recruit new customers from the website, then a competition incentive to signup to the newsletter works well.
The entire sign-up process should be very carefully thought out and implemented - it needs to be opt in and people should receive a welcome email....and if you want to turn them from subscribers to customers, the welcome email could include an incentive.
Again, Mailchimp would allow you to implement this.
If you aren't inundated with designers already, then I know a good one - just pm/email me.
