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!
Building subscriber lists is a common need for email marketers. The important thing to remember with this objective is that your email marketing should be focused on quality and not quantity. Because you could gain an additional 1,000 subscribers but they aren’t really interested in your brand and are therefore not going to add much value to your email database or your business.
If you're doing something right, and it's making an impact, your competitors will pick up on it. If your competitors start changing their own strategies and tactics, and if it seems like they might be doing this in response to your campaign, it's worth looking into. Identify your main competitors and analyse how their own email messaging has changed (if at all) during your campaign.
Make your offers feel relevant. If you offer people something they don’t think is relevant for them, they also think you don’t know them or understand their situation. Segmenting people based on their interests, problems, company sizes, and other things can help with that a lot. But it’s not enough. Your offer might be a perfect fit for them, but how you present it has to be a fit, too. Focus on describing their problems, how they’ll use the product or service, and what they will have in the end. Don’t talk about it from your perspective. No one really cares what you think about your product as much as they care about what they’ll get from it.
When it comes to deciding how to craft that perfect subject line, there appears to be really only one area to avoid: the subject line of 60 to 70 characters. Marketers refer to this as the “dead zone” of subject length. According to research by Adestra, which tracked over 900 million emails for its report, there is no increase in either open rate or clickthroughs at this 60-to-70 character length of subject line.
