Let's see how you can get as many opt-ins as possible.

Opt-in email list marketing no.1 is; Content, content, content. Yes, content is king and it is very important that you give your list as much quality content so they are eager to get your email. You must make your subscribers jump for joy each time they receive a message from you. That plays a big part in making your list responsive.

Tip no.2 is give something for free when they opt-in. Everybody loves freebies. Give them something useful for subscribing to your list.

Opt-in tip no.3 is create a viral ebook or software. You can be creative here and make a PDF file with something that is sitting on your hard drive. Or you can take a bunch of your articles and publish them in an ebook.

Don't have any of those laying around?

Don't despair. If you have a little money, go to elance.com or rentacoder.com and submit a project. You can probably get somebody to write that ebook for $50 to a $100. You can also check out the PLR (public licence rights) packages that are so cheap nowadays everywhere on the internet.

Software is so easy also. You can outsource that one too or check out a software called Mutli-media builder.

Opt-in email list marketing no.4 is organize a contest. Hey, everybody likes to win, right!

Give something valuable and relevant to your web site for subscribing is another good strategy.

No. 5 is joint venture. If you already have a list and want to get more subscribers, why not ask another list owner (like an ezine publisher or forum owner) to trade lists.

Both of you benefit and you know most people subscribe to more than one list.

Make the best offer you can.

Tip no. 6 is advertising. Buying ad space in another ezine that is not your competition but related somewhat to your niche can be another way to get subscribers.

Opt-in tip no. 7 is pay-per-click (PPC). The fastest way to build a list is through PPC ads like Google Adwords or Yahoo Searchmarketing. You have to budget and really keep a close eye on your campaigns because it can cost you dearly.

Opt-in email list marketing strategy no. 8 is backend offer. If you sell physical goods, you can include a note that tells them to visit your site with something that will add value and offer them to subscribe to your list once they get there.

If it is a service you sell, you can offer them to subscribe to your list on the thank you page.
