As an email marketer, you spend a lot of time figuring out how your subscribers interact with your brand. However, this tells only part of the story. Unless you can see how your subscribers interact as a whole—with other brands as well as your own—you can’t make an accurate assessment of a subscriber’s engagement level.
By segregating your subscribers based on how they interact with email as a whole, you will be better equipped to judge their overall email frequency tolerance.
Three major types of accounts
For this study, we grouped subscribers into three categories based on Return Path’s panel:
Why are these categories important?
Most marketers use engagement level as a basis for making decisions around send frequency. Best practices typically recommend sending more to engaged subscribers, as they’re less likely to complain, and sending less to disengaged subscribers because they tend to complain more, causing deliverability issues. In fact, our research found the exact opposite to be true.
Primary accounts are the most active as well as the most sensitive. These accounts belong to the “zero inbox” and power users. Email sent to these accounts are read and interacted with, accounting for 83% of all reads, but it also draws a surprising number of complaints. Primary inboxes account for roughly 24% of users among our panel, but generated 50% of all complaints.
Secondary accounts are moderately active, reading only a small percentage of email they receive. They may be “side” email accounts used for subscribing to promotions and checked only occasionally. These accounts make up 67% of all users in our panel, accounting for just 16% of total reads and approximately half of complaints.
Dead accounts were likely created and abandoned—not quite unknown users or spam traps yet, but well on their way. These accounts are rarely checked, let alone actively engaged. Dead accounts make up 9% of users in our panel and generate less than 1% of reads and complaints.
