For effective and actionable results, you should do A/B tests, which test two (or more) different approaches. For example, you could send half of your list one subject line, and an alternate subject line to the other half. You could also A/B test the two approaches with a small subset of your list, then send the winning headline to the rest of the list.
You can use this strategy to your advantage and increase your email list by giving people an incentive in return for their email. The giveaway could be free access to an e-book, a report, a gift hamper, or perhaps a lucky draw where people enter their emails and get a chance to win. A tantalizing offer is all you need for people to comply. For example:
Most of the how-to articles you read about list building strategies are actually talking about specific list building tactics. You know, like how to use SEO to drive traffic, how to use a specific type of squeeze page, or how to guest post. These are all specific actions you can take to get more traffic and subscribers, but they don’t constitute an overarching strategy.
I think the object of this part is to create a list of people's emails so that you might have a database of people to sell things to. The easiest way to create this email list is to offer them something free. That way people will be willing to sign up for your free whatever it is that you want to give them. Once you create a little form for them to put their name and email into, then you give them the free thing. It could be something they download, or it could be something tangible, such as something physical you send in the mail. It would be more expensive to do that, but the way you get around that is to do a raffle. If you offer something really good, something that costs money, like a gem or a ring or something similar, you could raffle it and still, people would be willing to give you their email just for the act of getting in on the opportunity to win the ring or the gem or whatever it is you would like to raffle. It could be a "Fidget Spinner." It could be anything.
Choosing an AppSumo product their target audience would like, they let people enter to win it by taking specific actions such as subscribing via email and sharing on Twitter. Because of the viral nature of social sharing, these giveaways amplify the initial promotion to quickly reach a larger audience, all while increasing the visibility of specific AppSumo products.
The most obvious and logical place to find interested email subscribers is on your website itself. If users are visiting your website (regardless of whether they purchase or make a transaction), they have an interest in the information or content that you're providing. Every page of your website should include an email sign-up box that allows users to join your mailing list. We'll discuss the best practices for creating that email sign-up box later in this section. However, every visitor to your website is a potential email subscriber.
Sponsor a video contest in which customers create a one-minute video about why they like your business, products or services. Ask them to send the videos to you and post them to your Facebook page. Invite visitors to vote on which video should win a cash or merchandise prize. Include an email opt-in on your Facebook page. Be sure to follow Facebook’s rules regarding contests.
