Here are ten natural "sunset" sentences, spanning the workplace channels and objects where the word actually appears -- roadmap docs, developer notices, procurement notes, executive summaries, customer emails, HR notices, and more.
"Sunset" appears naturally across a wide range of workplace channels and objects -- API and feature announcements, policy and benefit memos, vendor and procurement notes, and client-facing updates -- always with a direct object, and usually with a date, replacement, or support detail attached.
Product and engineering channels
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."
Client-facing and HR/non-tech channels
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."

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 directly transitive verb with a real object and no preposition before that object, matching the grammar pattern every other example in this article and the rest of the batch follows. A sentence like "we sunset" with no object, or "sunset on/from X," is never a natural model to copy.
What changes across channels, and what never does
Looking at the ten sentences together, the channel and the level of formality shift constantly -- a Slack update reads nothing like a board memo, and a customer email carries a different tone than an executive portfolio summary. What never shifts is the underlying grammar: a real object immediately after the verb, a timeframe preposition that matches the kind of date, and, in most of the strongest examples, one added detail that answers the reader's next question before they have to ask it.
That consistency is useful precisely because it means the hardest part of writing a good sunset sentence isn't grammar at all -- it's picking the right level of formality and the right concrete detail for the specific channel and audience in front of you. Once the grammar is automatic, the real skill this article is modeling is matching tone and detail to context, using the same reliable sentence structure underneath 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 register of a sunset sentence to product, executive, or client-facing writing
- checking a draft sentence against the shared grammar pattern every example here follows
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."
Ten channels, one grammar pattern -- sunset never stops being a directly transitive verb with a real object.
Once that pattern is automatic, writing a natural sunset sentence for any channel is mostly a matter of picking the right detail to attach.
