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.
Email design matters in any successful email marketing campaign. If your emails look terrible, that reflects badly on you, and can make people stop reading. With more people than ever reading emails on mobile devices, it’s important to use a responsive email template so your email resizes automatically whether people are reading it on a phone, tablet, or desktop.
The Preheader references the area before the main content. It's an excellent opportunity to grab a bit of extra pre-content web real estate. It's got a degree of prominence in the inbox, so it would be a waste not to use it for promotional purposes. Try popping a couple of links in here. Some companies find that they get the most clicks on links within their preheader
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.
