There are many forms of free marketing online, and it's important to not only know what they are, but to know HOW to use each one effectively. There are certain points that can make the email list difference between success and failure - and if you know what you're doing, you can make sure you're in the success category! Free marketing online - using email lists for marketing products to a mass audience You're sure to have received more than your share of spam emails, so you probably know how much damage that can do, and I'm sure you'd never deliberately spam anyone.
However, it's very easy when starting off in free marketing online, to fall into the trap of unintentional spamming. Unless you use a good email opt-in system, it is possible to be accused of spamming even if your intentions were good. You need the prospect to acknowledge that they've agreed to receive emails from you. Never buy email lists - the chances are, at the very least many of the emails will be inactive, and at worst, you'll be opening yourself up to spam complaints. Creating an opt-in email system You could do this manually using your own email account, but it would be very risky.
I advise either using a well-established reliable paid-for service like Aweber, or you could do a search for "free opt in email". Although I've done a lot of free marketing online, I've never used a free opt-in email service, so I don't know how reliable they are - make sure you check them out thoroughly before using them. However, I've used Aweber for years, and can highly recommend it. Building email lists marketing appropriate products The most reliable way to build a good, well-targeted email list is to create a "squeeze page". A squeeze page is a web page that has an opt-in form on it. A visitor to the page can fill in the form - usually with just their name and email address - and by doing that, they're agreeing to receive email from you.
