Should you email inactive subscribers who haven’t opened or clicked any of your promotional emails in a long time? That seemingly simple question is actually fraught with nuance and complexity. But it’s critical to have a clear answer because maintaining your email engagement levels is probably the biggest factor determining your email deliverability.
Let’s decode that question by discussing five truths about inactive email subscribers.
Truth #1: ‘Inactive Subscriber’ Does Not Have a Standard Industry Definition
Every brand has its own unique definition of what an inactive subscriber is. Brands guide that definition largely by the negative effect that emailing these subscribers has on their deliverability.
However, many brands use a series of terms to describe various degrees of inactivity, almost always for the purposes of treating each of these groups differently. Typically, “inactive” is a point somewhere in the middle of the inactivity spectrum. When a brand seems a subscriber inactive, it often means that the brand emails them less frequently. For example, brands may only send the week’s most important campaign. They may also send a re-engagement campaign series to these subscribers, too.
Prior to a subscriber becoming inactive, many brands define a period where they’re disengaged or lapsed. Often, these subscribers aren’t mailed any less often, but the emails might include targeted subject lines or body copy that’s designed to spur engagement. Sometimes these subscribers actually receive more messages, including triggered re-engagement campaigns, in an attempt to generate engagement before the problem gets worse.
After a subscriber is inactive for a while and re-engagement efforts have been unsuccessful, these subscribers become long-term or chronically inactive. Sometimes they’re colorfully referred to as zombies. Brands generally send these subscribers a re-permission campaign to try to get them to explicitly reaffirm their interest in receiving your emails. If they don’t re-confirm their permission, they’re suppressed from all future mailings.
Truth #2: Lots of Brands Make Exceptions Around Inactives
Businesses are constantly under pressure to expand the reach of their messages by expanding their audience. In a pitch, that often means temporarily changing their rules around inactives.
For example, during the heart of the holiday season around Black Friday and Cyber Monday, retailers risk potential deliverability problems. Why? Because in exchange for boosting short-term sales, they email more campaigns to more inactives. Often that gamble pays off, but not always.
Beyond seasonal exceptions, some brands also make exceptions for individual subscribers. For example, some brands resist suppressing chronically inactive subscribers who are also high-value active customers. They take that risk because of our next truth.
