Newsletters are long-haul engagement. They serve as check-ins with your subscribers, as well as offering generalised engagement points. Newsletters are a way of both driving and maintaining engagement – at worst they serve as a reminder of the relationship the recipient has with a brand, but usually, they do a lot more. Provide as many engagement points/links as you can within your newsletters, and you'll be surprised at what crops up!
A trigger can also be a passive customer behavior, such as not opening your last few emails, not logging in to use your service for a while, or downloading a product without downloading the tutorial or an important related resource. These types of drip campaigns can help re-engage customers who were moving through the customer lifecycle but have somehow gotten “stuck.”
High reach: When people join your email list (subscribe or “opt in”), you can reach them. If they just like your Facebook page, for example, it’s unlikely that they’d see many of your updates. Sure, not everyone opens your emails, but the numbers are heavily in favor of email marketing compared to other similar marketing tactics. I’d rather get 1,000 new email subscribers than 10,000 Twitter followers.
Surprise: Customer loyalty is the key to success. And you can reward your loyal customers by giving them something for free every now and then. Create a “surprise” email that sends an automated email to your best customers that offers a free yearly license to your software for them to use, a gift card or even a coupon code to redeem a box of cupcakes. It’s a small cost for your business but, the reward is huge!
Part of the problem is that people are confused about the difference between ‘strategy' and ‘tactics'. It's essential not to get these two confused. They are related – tactics are a vital part of what makes a strategy work – but they’re not the "be all and end all." Too many people neglect a full and comprehensive strategy in favour of a bunch of loosely-connected tactics. So, to recap:
