Email Marketing will grow your business faster than any other marketing medium!

I use and recommend GetResponse. They have a great selection of tools to make your e-mail campaigns stand out from the competition. You can even set the frequency of the e-mails you send out which will be done automatically once you have created & uploaded them to your campaign.

Don't just take my word for it though, check out for yourself
