Every ESP will give you tools to create an opt-in form for your site. Generally speaking, the less information you ask for (at this initial stage, at least), the better. The more information you ask for, the less likely your prospect is to complete the process. You’ll obviously need to ask for an email address, and I also highly recommended that you ask for a first name so you can personalize your emails. However, asking for any information beyond these two fields can decrease conversion rates significantly without adding much valuable data.
You probably have subscribers on your list that haven’t opened your emails for six months, one year, or even more. Whether their email address has become invalid, or they’re simply not interested in your messaging, consider removing them from your email list. Removing these subscribers will negatively affect your subscriber count, but it will positively impact your list quality, which is more important. If you get rid of these disengaged subscribers, you should see engagement rates rise. You can send a re-engagement campaign asking these subscribers if they’d like to remain on your list or be removed. If you don’t get a response, you can feel confident removing them.
Do you have an older list that you suspect has mostly decayed? Create an engaging opt-in message and send it to your old list encouraging contacts who wish to re-opt-in -- promising to remove all contacts who don't respond. Though it might seem counterintuitive to remove folks from your email lists in order to grow them, emailing only engaged contacts could improve your deliverability and increase the odds of your email getting shared with those outside your current contacts database.
If you don’t wish to adopt any of the above-mentioned strategies to build your email list, you can also use blogger outreach programs and software that help promote your company, product or service. They post about you on their site in exchange for product, payment or any service, as a result of which you get mentioned in several places online which is likely to create email traffic for you.
As for social media, it has been a powerful marketing tool for me because I intend to connect with as many people as possible. People know people, and if you develop a caring connection with someone you leverage your presence like no other practice. The key is to make things personal, not business. Reverse the famous Godfather quote and you’re good to go.
Considered a form of interruption marketing, interstitials are any page or pop-up that forms a roadblock to users’ path to content, either by displaying over the content or interrupting it. Users have no choice but to interact with the display before they can proceed. Forbes was a classic example of the “before” interstitial (also known as a “prestitial”).
Unsubscribe rates track when you’ve finally lost permission for good. When someone unsubscribes from your list, it means they’ve gotten to the point where they’d like to formally revoke permission and never hear from you again. Marketers tend to focus on unsubscribe rates as the ultimate measure of when permission is lost. But the truth is, you probably lost permission far before your subscriber reached for that unsubscribe button.
What I will say is that opt-ins on your website and social media will be your friend. Supply traffic coming from Google, Facebook, and Twitter with offerings that they must sign up for. Use a free ebook, a checklist, a free podcast, or even an email course (which you can set up with your autoresponder service) to get them to subscribe to your list.
