Here are ten natural "sunset" sentences from common workplace writing. You will see the word in roadmap docs, developer notices, procurement notes, executive summaries, customer emails, HR notices, and more.
"Sunset" works with many workplace topics. These include APIs, features, policies, benefits, vendor services, and customer tools. In an active sentence, the verb needs a direct object. A passive sentence puts that object before the verb. The sentence also often includes a date, a replacement, or support details.

Roadmap doc, passive pattern with a firm date: "Per the Q3 roadmap, internal search API v2 will be sunset on November 15, with all consumers required to migrate to v3 before that date."
Developer notice, passive announcement paired with a migration-guide link: "The authentication SDK is being sunset next month; see the migration guide at go/auth-sdk-migration for the full cutover steps."
Slack update: "Heads up -- the on-call alerting tool is getting sunset next sprint; migrate your rules to the new system before then."
Vendor, procurement, and executive channels
Procurement note, vendor tier: "Procurement has approved sunsetting the enterprise support tier with our facilities vendor, effective the start of next fiscal year."
Executive/portfolio summary, several items across a quarter: "This quarter's portfolio review recommends sunsetting three underperforming pilot programs: the referral-bonus trial, the vendor scorecard dashboard, and the quarterly all-hands survey tool."
Board memo: "We recommend the company sunset its legacy retail POS system by mid-2027, in favor of the cloud platform already piloted in three regions."

Customer email, sunset paired with a transparent support detail: "We're sunsetting the legacy invoicing portal on August 31; your account will move automatically to the new billing dashboard, and support is available by chat through September."
Non-tech production example, applying sunset to an internal program rather than software: "HR is sunsetting the annual paper enrollment packet for benefits, replacing it entirely with the online enrollment portal."
HR notice: "The flexible parental-leave pilot will be sunsetted at the end of this fiscal year, with every eligible employee transitioned to the standard policy automatically."
The "in favor of" pattern
"Sunset X in favor of Y" collocation, naming the replacement in the same clause: "The facilities team will sunset the shared printer fleet in favor of a single managed-print vendor starting next quarter."
What every sentence above has in common
Every sentence above uses sunset as a transitive verb. In an active sentence, a real object comes right after the verb. In a passive sentence, that object moves before the verb: "the API will be sunset." A sentence like "we sunset" with no object is not a natural model to copy. Neither is "sunset on/from X."
What changes across channels, and what never does
The channel and level of formality change across the ten sentences. A Slack update does not read like a board memo. A customer email has a different tone from an executive summary. But the verb remains transitive in both active and passive forms. Any preposition used with the timeframe must fit the type of date. The strongest examples also add one useful detail. This often answers the reader's next question.
This steady pattern makes the grammar easier. The harder part is choosing the right tone and detail for your channel and audience. Once you know the grammar, focus on matching the context. The same reliable sentence structure works in every version.
Practice scenarios
Practice using sunset in situations like:
- producing a natural sunset sentence for a channel you don't normally write in
- matching the formality of a sunset sentence to product, executive, or client-facing writing
- checking whether a draft uses the active or passive grammar pattern correctly
Useful practice phrases:
- "Internal search API v2 will be sunset on November 15."
- "We're sunsetting the legacy invoicing portal on August 31."
- "The facilities team will sunset the shared printer fleet in favor of a single managed-print vendor."
Draft the next sentence
Ten channels use the same core grammar. Sunset is transitive, whether the sentence is active or passive.
Once that pattern feels natural, focus on adding the right detail for the channel.
