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.
When you're using email as a marketing tool, you're working on a pretty personal basis. This isn't ‘drive-by' stuff -you're directly targeting customers from their inboxes. There's a huge amount of potential which comes with this kind of marketing... but you'll only reap that potential if you REALLY understand both the marketplace you're operating from, and the audience you're talking to.
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.
In addition to linking to Letter Shoppe's designs (available on merchandise that is ultimately sold by RedBubble), the email campaign includes an endearing quote by the Featured Artist: "Never compromise on your values, and only do work you want to get more of." RedBubble's customers are likely to agree -- and open other emails in this campaign for more inspiring quotes.
When you want to create a win-back campaign: Develop a series of win-back emails to encourage inactive subscribers to re-engage, and utilize post-sending actions to automatically perform a specific list action on subscribers after they receive the final email in the series. This could be used to update one of their merge fields, move those subscribers to a different interest group, or to remove them from your list completely.
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.
