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.
Minimal risk: Some top marketers expect to burn through $10,000 of advertising budget before even knowing if they can make a campaign profitable. (Nope, that’s not an exaggeration. But I’d usually aim for a few hundred dollars—not thousands.) With email marketing, the costs are much, much lower. A simple email marketing software like AWeber is very affordable even if your business isn’t a huge success, yet. And even if you go with something advanced like Infusionsoft, you’re still far away from the kinds of investments many other marketing tactics require. Sure, email marketing and advertising aren’t directly comparable (advertising is mainly used to reach new prospects). But you get the point.
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.
The success of daily deal email illustrates this. Customers gain value from a ‘daily deal' email and will come to anticipate the email in their inbox every morning. Tagging links in ‘daily deal’ emails will tell you a lot about the journeys within a given customer profile, as well as about preferences and behaviours. The ultimate sell is not important – what you are doing with ‘daily deal' (or ‘weekly tips') email content is building a relationship with your customers and learning more about how journeys within your brand work. All this information is important and can be put to use on later campaigns.
For example, a young company experiences growth and considers purchasing an employee health insurance plan but knows little about options. A health insurance company offers an online quiz with questions such as what state the company resides and what employee health benefits laws apply based on the number of employees, what to look for in health insurance offerings, etc.
Will people understand what you’re trying to say? It’s usually better to avoid topics (or opinions) that are complex if many people are extremely passionate about them. For example, sharing almost any opinion about immigration policy is usually a bad move, unless your audience is unusually homogenous. You could agree 99% with someone and still piss them off by using the wrong term just because they have such a strong “either you agree 100% with us, or you’re our enemy” mentality. I once pointed out that I think it’s unacceptable to capture and torture people for years—especially if they aren’t charged with any crime, there’s no evidence they’ve done anything wrong, and they’re children. I got several emails back from people saying, “you have no idea what you’re talking about” or “you should stick to marketing and leave politics to people who understand it.” They took it as commentary on geo-politics. I just said I’m not okay with pointless torture of children. I thought we’d all agree on that.
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!
That isn’t to say that sales-y promotions couldn’t ever create results—as marketing “gurus” have proved. The results just aren’t as good as they could be. Take the biggest gurus’ results—the ones they boast about—and calculate their conversion rates. Often their marketing is comparatively ineffective. They just have massive volume, so the sales numbers are impressive.
