This company has a good resourece for companies to promote there products on the Internet but watch out for a couple of things:
1) Negotiate with the cost for the design of the Email Design because I got them down to £80 from £175 in about 30 seconds
2) With all email marketing exercises its all down to the offer and whether the email is actually opened. So don't think you will become a millionare overnight,
3) Treat this as a brand building exercise rather than a sales tool. Helps to manage your expectations as the campaign we conducted got traffic but only a small portion was sales.
4) Only go with the starter campaign as this will give you an indication on whether Email MArketing will actually work for your business.
In conclusion this service can be excellent in building traffic and awareness of your product or sevice but don't rely heavily on it for ROI
