Digest (Rollup)
Updated July 21, 2026
An aggregated summary of multiple changes delivered on a schedule (daily, weekly) instead of individually. Reduces volume while maintaining awareness.
Also known as: Rollup, Digest email, Digest notification, Summary email, Activity digest, Roundup
A digest, also called a rollup, is a scheduled summary that bundles multiple change events or notifications into a single message delivered on a fixed cadence, most often daily or weekly, instead of firing an alert for each event as it happens. The point is volume control without loss of awareness. A watcher who follows a dozen competitors can generate dozens of individual signals a day; a digest collapses that stream into one predictable delivery a reader can scan in a couple of minutes and act on, rather than an inbox of one-off pings that quietly trains people to ignore the channel.
The pattern predates competitive intelligence by decades. It comes from email mailing-list software, where "digest mode" let a subscriber receive one combined message of a list's daily traffic instead of every post individually; the idea was formalized at the protocol level in RFC 2046 (1996), which defines the MIME multipart/digest type for bundling several messages into one container. Modern SaaS notification systems carried the same terminology forward, and digest is now a standard notification-preference feature across many products. "Rollup" is used interchangeably in notification UX, though it carries a separate, older meaning in databases and OLAP that is unrelated to messaging.
In competitive-intelligence tooling, digests bundle competitor signals such as funding news, ad launches, content updates, and job postings into a scheduled roundup delivered over email, Slack, or Teams. They typically sit alongside real-time alerts, which handle the small set of time-sensitive events, while the digest absorbs the higher-volume, lower-urgency stream.
How a digest is assembled and delivered
A digest is the output of a batching process. Between deliveries, the system holds incoming events in a queue rather than notifying on each one. When the scheduled window arrives, it collects everything accumulated since the last send, groups and orders it, and packages it into one message. Cadence is the defining property: a digest is calendar-based, tied to a clock or a day of the week, rather than triggered by any single event.
Grouping is what makes the result readable. Events are usually organized by competitor, by source type such as pricing, blog, or hiring, or by importance, so the reader gets structure instead of a flat list. Empty windows are typically suppressed, so no message goes out when nothing happened. Delivery is push-based: the digest arrives in email or a chat channel without the reader opening the product. That distinguishes it from a persistent notification center, which is a pull-based list a user checks on their own initiative.
Digest vs. real-time alerts
Digests and real-time alerts sit at opposite ends of the urgency spectrum, and most mature setups run both. A real-time alert fires immediately, one per event, and is reserved for signals where a delay has a cost: a competitor's pricing change, a major product launch, a funding round, or an acquisition. A digest deliberately delays and batches, trading immediacy for a lower interruption rate.
The practical question is not which to use but where to draw the line. A common routing convention sends high-priority, time-sensitive signals as instant alerts and routes higher-volume, lower-urgency signals, such as routine content updates, minor messaging shifts, and job postings, into a daily or weekly digest. Getting that split right is what keeps a real-time channel credible; when every low-stakes change also fires instantly, readers stop distinguishing the urgent from the routine and the alert channel loses its meaning.
Digest vs. batching, and vs. a newsletter
Batching is the general mechanism of holding and grouping notifications before delivery; a digest is the specific artifact that results when batching runs on a fixed calendar cadence. Batching can also be threshold-based, releasing once a count of pending items is reached, or activity-triggered. A digest is the calendar-scheduled case of that broader pattern, which is why the two terms are often mentioned together but are not identical.
A digest also differs from a newsletter, even though both arrive as periodic emails. A newsletter is typically curated editorial or marketing content sent to a broad audience, the same body for everyone. A digest is transactional and personalized: it summarizes a specific reader's own watchlist or pending events, so no two recipients necessarily see the same contents. In competitive intelligence the distinction matters because a digest is evidence about a defined set of tracked competitors, not general-interest reading.
How CI teams use digests
For a competitive-intelligence program, the digest is the workhorse channel for keeping stakeholders aware without overwhelming them. Product marketing, sales enablement, and leadership rarely need every website change the moment it lands; they need a reliable, scannable summary of what moved across the tracked set since they last looked. A weekly rollup suits executives and cross-functional partners, while an operator closer to the field may prefer a daily one.
Digests also reduce the maintenance cost of broad monitoring. Because the format tolerates volume, a team can track more competitors and more source types than an all-instant approach would allow, letting the digest absorb the long tail of minor changes while reserving interrupts for the few signals that warrant them. A workflow that continuously monitors competitor websites, pricing pages, news, and job postings can feed that raw stream into a scheduled roundup, so awareness stays current without any single change demanding attention the instant it appears.

Frequently Asked Questions
What is a digest notification?
It is an automatically generated message that combines all the notifications or change events accumulated over a set period into a single scheduled delivery, instead of sending one alert per event. Rather than a ping for each competitor update, a subscriber receives one bundled summary at a fixed time, such as every morning or once a week, that they can scan in one pass.
What is the difference between a digest and a rollup?
In notification products the two are used essentially interchangeably: both mean a scheduled, aggregated summary of multiple events. The main caveat is that rollup is the more overloaded word. It has a separate, older meaning in databases and OLAP, where the SQL ROLLUP operator and the roll-up cube operation aggregate data up a dimensional hierarchy, which is unrelated to the messaging sense.
How often should a digest be sent, daily or weekly?
It depends on the volume and urgency of the signals and the reader's role. Daily digests suit operators who track many competitors and want to stay close to the stream, while weekly rollups suit executives and cross-functional partners who need a periodic overview. Either way, digests are meant for lower-urgency, higher-volume changes; genuinely time-sensitive events belong in real-time alerts.
How do digests reduce alert fatigue?
Alert fatigue sets in when a channel produces so many individual notifications that people start ignoring all of them, including the important ones. A digest attacks the root cause by collapsing many events into one predictable, scannable delivery. That cuts interruption frequency while preserving awareness, so readers keep paying attention to the channel instead of muting it.
Is a digest the same as a newsletter?
No. A newsletter is typically curated editorial or marketing content sent as the same message to a broad audience. A digest is transactional and personalized, summarizing one specific reader's own pending notifications or watchlist activity, so recipients can see different contents. Both may arrive as recurring emails, but their purpose and how their contents are generated differ.
