What Is an Embargoed Press Announcement?
An embargoed press announcement is news given to selected journalists before it is public, on the agreed condition that none of them publishes it before a stated date and time.
The cleanest published definition comes from EurekAlert!, the science news service run by the American Association for the Advancement of Science: “A news embargo is a prohibition against making public, in any way, certain information before a specific date/time” (EurekAlert!). The NYU journalism handbook describes the trade: organisations “provide advance access to material that they consider newsworthy to journalists who agree not to publish anything about that material until a set date” (NYU). The word that matters is agree. Our explainer do press embargoes still hold found that embargoes hold where the journalist signed or agreed to something, and that breaks are usually handled by lifting the embargo for everyone.
How to Plan an Embargoed Press Announcement at a Glance
| Step | Action | Expected result |
|---|---|---|
| 1 | Decide whether an embargo is the right tool | A written choice: embargo, exclusive or open release |
| 2 | Set the lift date, time and time zone | One lift time that matches your own publication |
| 3 | Choose recipients and get their agreement first | A list of journalists who have said yes |
| 4 | Prepare the embargoed package | Release, facts, images and contacts, each marked |
| 5 | Send with enough lead time and offer access | Journalists have time to interview and check |
| 6 | Plan what to do if the embargo breaks | A pre-agreed early-lift decision and statement |
| 7 | Lift on time and publish your own version | Your release, newsroom page and posts live at the lift time |
Time: planning over one to two weeks before the lift (our estimate; Nature's press mailing goes out six days ahead). Tools: a release, a contact list, email, your newsroom page and, if used, a wire service. Cost: none for an email embargo; wire distribution is priced by the provider. Skill level: intermediate.
What You Need Before Starting
- The final, approved announcement text and every fact in it checked; see how to write a press release.
- A named owner for the embargo and a named spokesperson available during the embargo period.
- A short list of journalists whose beat fits; see how to build a media list.
- A page ready to publish at the lift time on your own site; see how to create an online newsroom.
- For a listed company, the view of securities counsel on whether the news is material.
Step 1: Decide Whether an Embargo Is the Right Tool
Use an embargo only when journalists need time to report the story well. That is what embargoes are for: NYU says proponents argue they “allow reporters time to develop fuller stories, rather than rushing to beat the competition.”
Process: ask three questions. Does the story need explanation, data or interviews? Do you want several outlets at once, or one in depth? Is any of it material to a listed security? If one outlet in depth is the goal, offer an exclusive instead. If the news is simple, release it openly. If it is material, Regulation FD requires public disclosure “Simultaneously, in the case of an intentional disclosure” to the market professionals and holders it lists (17 CFR 243.100); journalists are not on that list, but exchange rules and insider-trading law still matter, so take advice. Expected result: a recorded decision. Common mistake: embargoing routine news to make it look bigger. NYU's handbook warns that embargoes “have become overused in some fields”.
Step 2: Set the Lift Date, Time and Time Zone
Write the lift time as a date, a clock time and a time zone, and use the same wording on every document. Journals publish theirs precisely. Nature says the press mailing and papers are “embargoed until 1600 London time/1100 US Eastern Time on the day of publication” (Nature). PLOS ONE says its articles “are embargoed until 2 p.m. Eastern Time, USA, on the date of publication” (PLOS ONE).
Process: choose a time when your spokesperson is available and your own page can go live, and match the lift to that moment. Avoid times that fall on a different date in another key market. Expected result: one line, such as “Embargoed until 09:00 US Eastern Time, Tuesday 3 November 2026”. Verify: convert it for each market on the list. Common mistake: “embargoed until Tuesday morning”. Our explainer records an early lift caused by time-zone confusion.
Days before the publication date, as stated by Nature

One journal's schedule, shown as a published example of lead time. PLOS ONE states a different lift time, 2 p.m. US Eastern on the publication date. Your own lead time is a choice, not a rule.
Step 3: Choose Recipients and Get Their Agreement First
Ask before you send. An embargo is an agreement, and an agreement needs a yes. EurekAlert! makes this formal: “All reporter- and PIO-registrants must digitally sign an embargo agreement prior to obtaining an account on EurekAlert!”
Process: email each journalist a two-line summary without the news itself, state the lift time, and ask whether they will accept the material under embargo. Send the package only to those who reply yes. Keep the list short; every extra recipient is another chance of a break. Expected result: a list of named journalists who have agreed, with the date of each reply. Common mistake: sending the full release to a large list with “EMBARGOED” in the subject line. Our press release guide gives the same rule: use an explicit embargo line only when journalists have agreed in advance.

Ordinal ranking. EurekAlert! requires reporters and press officers to digitally sign an embargo agreement before getting an account; our explainer found that an unsolicited embargoed release creates no obligation on a journalist who agreed to nothing.
Step 4: Prepare the Embargoed Package
Give journalists everything they need to report without chasing you. A thin package defeats the purpose of the embargo.
Process: put the embargo line at the top of every document and in every email subject. Include the release, a fact sheet, images with credits, the spokesperson's availability during the embargo, and any customer or partner contacts. Our definition of a press kit lists the standard contents. Keep the same embargo line on files and download links. Expected result: one folder or email that answers the obvious questions. Common mistake: a hosted page that is public before the lift because its address is guessable or indexed.
Step 5: Send With Enough Lead Time and Offer Access
Send early enough for real reporting. Nature's press office “distributes embargoed mailings highlighting upcoming content to registered journalists six days in advance of publication”, and its authors may talk to the media from six days before publication.
Process: choose a lead time that fits the complexity of the story; a few working days is common for business news, and longer for research. Let journalists seek outside comment. Nature permits journalists to show papers “to independent specialists a few days in advance of publication, under embargo conditions, solely for the purpose of eliciting comment.” NYU criticises embargoes that forbid this, saying they turn journalists “into stenographers.” Expected result: interviews booked during the embargo. Common mistake: sending the night before, which turns the embargo into a deadline.
Step 6: Plan What to Do If the Embargo Breaks
Decide now that a break means lifting the embargo for everyone. That is the documented norm: our explainer records journals lifting embargoes early after breaks, and the specialist blog Embargo Watch logged such cases from 2010 to 2021.
Process: name who decides, write the one-line notice to the list (“The embargo on X is lifted, effective now”), and prepare your page so it can be published early. Draft a short statement in case the early story is wrong; see how to write a crisis holding statement. Set up alerts for your company and product names; see how to monitor brand mentions. Expected result: a plan you can run in minutes. Common mistake: keeping the embargo for everyone else after one outlet has published, which punishes the journalists who kept their word.
Step 7: Lift on Time and Publish Your Own Version
At the lift time, publish your own release and newsroom page, then post on your channels. Journalists who honoured the embargo should not find you a step behind.
Process: schedule your page and any wire distribution for the lift time in the stated zone, check the schedule the day before, and have someone watching at the moment of lift. If you use a wire, our comparison of PR Newswire and Business Wire covers distribution options. Expected result: your version and the coverage appear at the same time. Common mistake: a wire or CMS set to the wrong time zone.
How to Verify It Worked
- No early coverage: a search for the company and announcement before the lift time returns nothing new.
- On-time publication: your page carries the lift time as its published date and is indexed afterwards; see how to check if a page is indexed.
- Coverage logged: each story from the agreed list is recorded with its time of publication.
- Agreements kept: every recipient appears on the agreed list with a dated yes.
How to Choose an Embargo, Exclusive or Open Release
| Situation | Recommended route | Why |
|---|---|---|
| Complex news that needs time to report | Embargo to a small, agreed list | Journalists can read, interview and seek comment before publishing |
| You want depth in one chosen outlet | Exclusive, not an embargo | One outlet, one decision; see the linked definition |
| Simple news with nothing to explain | Open release at a set time | An embargo adds risk without benefit |
| Material information at a U.S.-listed company | Legal advice first; usually simultaneous public release | Regulation FD and exchange rules apply to selective disclosure |
| Event or briefing to announce | Media advisory, with the news itself held | Tells journalists when and where without giving the story away |
| Many outlets, no prior relationship | Open release; do not send unsolicited embargoes | An unagreed embargo creates no obligation |
If you are announcing an event or briefing rather than news, a media advisory tells journalists when and where without giving the story away.
Common Problems and Fixes
| Problem | Likely cause | Fix |
|---|---|---|
| A journalist publishes early | Misread time zone, or no agreement | Lift for everyone at once and tell the list; then ask why |
| Journalists say they never agreed | Release was sent before consent | Agree first, then send, every time |
| Coverage appears at different times | Lift time stated without a time zone | State date, time and zone on every document |
| Your own site goes live early | CMS or wire scheduled in the wrong zone | Schedule in the zone stated in the embargo line and check the preview |
| Few journalists engage | Embargo offered to people outside the beat | Rebuild the list from recent bylines |
| A social post leaks the news | Staff or partners not told the lift time | Brief everyone who knows, in writing, with the time |
What Not to Do
- Do not send unsolicited embargoed releases. Consequence: no obligation exists and the news may run early. Correction: agree first, as in Step 3.
- Do not set a lift time without a time zone. Consequence: staggered or early coverage. Correction: date, time and zone on every file.
- Do not forbid journalists from seeking comment. Consequence: thinner stories, and some journalists will decline. Correction: allow outside comment under embargo, as Nature does.
- Do not embargo material information without legal advice. Consequence: possible disclosure problems for a listed company. Correction: involve counsel at Step 1.
- Do not punish the outlets that kept their word. Consequence: lost goodwill. Correction: lift for everyone after a break.
Frequently Asked Questions
What is an embargoed press release?
A release given to journalists before it is public on the agreed condition that they do not publish before a stated date and time. EurekAlert! defines an embargo as a prohibition against making information public, in any way, before a specific date and time.
Is a journalist legally bound by an embargo?
Usually not by law. An embargo binds through agreement, and the strongest versions are signed, as EurekAlert! requires. A release sent unsolicited to someone who agreed to nothing creates no obligation.
How far in advance should I send an embargoed release?
There is no rule. Nature sends its embargoed press mailing six days before publication. For business news a few working days is common; allow enough time for interviews and outside comment.
What time should an embargo lift?
Any time that matches your own publication and your spokesperson's availability. State the date, time and time zone. Nature lifts at 1600 London time; PLOS ONE at 2 p.m. US Eastern.
What should I do if someone breaks the embargo?
Lift it for everyone immediately, tell the whole list, publish your own page and then find out what happened. That is the documented norm among journals.
Can a public company embargo financial results?
Take securities counsel advice first. Regulation FD requires simultaneous public disclosure when material nonpublic information is intentionally given to the market professionals and holders it lists, and exchange rules also apply.
