Research Findings
Patterns that consistently emerged across the dataset — regardless of account age, region, or inbox size.
Promotional and marketing emails make up approximately 41% of all inbox volume — the single largest category. Most are sent from brands users signed up for years ago and have long since forgotten.
68% of newsletter subscriptions go unread for 30 or more consecutive days. Despite this, most users keep subscriptions active, allowing the volume to compound month over month.
Users underestimate how much storage junk emails consume by a factor of 3 on average. Promotional emails with embedded images and HTML markup are significantly larger than plain-text messages, and the cumulative effect compounds over years.
Inbox volume is highly concentrated. The top 5 senders in any given inbox account for approximately 35% of all email volume. This means a small number of high-frequency senders — often retailers and SaaS platforms — are responsible for the majority of clutter.
Users who perform a full inbox cleanup at least once per year accumulate 40% fewer junk emails in the following 12 months. Breaking the pattern of senders who receive no engagement signals resets algorithmic filtering across platforms.
