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.
The downside of just making offers is that they’re not useful on their own. People on your list won’t receive any value from you unless they buy what you’re promoting, so they have little reason to stay subscribed. That’s why this email marketing strategy doesn’t work alone. And it’s why many e-commerce sites struggle to keep people interested. There are a few exceptions (e.g., Groupon) that rely entirely on making offers—but then the reason people joined the list was specifically to receive those offers.
Be friendly. Feel free to use a casual tone in your email newsletters. Since most emails come directly from one person, people expect human voices in their inboxes. There's a good chance your subscribers are already in a informal frame of mind when they're checking their email, so an overly formal or stodgy voice might seem out of place. Plus, they've given you their email address, so you're already on a first-name basis. If you collect first names on your signup form, you can dynamically include them in your email greetings.
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.
Based on all the information we have gathered during our in-depth research we assign a magic score to each vendor. This is based on factors that affect any solo ad purchase (for e.g: CPC, Sales, Conversion rate etc). We use our proprietary algorithm to do this. As a rule of thumb, higher the Magic Score, better the solo ad experience is going to be.
You might consider making the language in your alt text actionable, such as "Click here to download the ultimate content creation kit." Actionable alt text will essentially turn every linked image into another CTA. So, even if someone doesn't see the snazzy GIF of my latest offer (or if they hover their mouse over an image that does show up), the alt text will beckon them to click.
If you’re not already segmenting, this is a great place to start. CPC is a strategy-based customer segmentation tool focused on profile descriptor fields. For B2C retailers, this would include age, sex and geography. For B2B companies, this will consist of the size of the company, job role and the industry sector or application they operate in. This example shows a female and male creative with the products that are included in the content changing based on the gender.

Technology has a significant impact on consumers’ expectations, and those expectations impact how subscribers engage with your email marketing. Brands need to continually demonstrate that they know their customer, which can make it a challenge to stay on top of the evolving context of marketing. An email strategy can make all the difference between building a relationship with your customers and sinking without trace.


One of the great things email has going for it is that it can adapt on a dime and turn on a penny, meaning that it has the potential always to be relevant and timely. This is very different from social media posts, which are less intensively targeted, less time-focused, and work on more of a broadcast basis. The capacity to intensively segment, target, and stream your email marketing also helps you to narrow your analysis to certain points. By doing this, you can learn a lot about your brand, your customers, and your marketing profile in general.

Personas provide a multi-dimensional method of targeting. They’re based, as the name suggests, on a projected persona for each customer ‘type’. Get it right, and personas can help you enormously in both predicting behaviour and personalising your communications. Personas are a powerful technique, and they’re increasingly used to improve the usability and customer centricity of communications.
