Rescheduling a Christmas party after the invitations have gone out comes down to four moves: update the invitation itself, actively tell every affected guest what changed, reconfirm attendance when the change calls for it, and review any reminders you scheduled before plans shifted. Greenvelope supports each step from the same mailing you already sent, so you are managing one invitation, not starting over. The steps below work the same way for an office party, a client reception, or a gathering at home.
Match Your Response to the Change
Not every change needs the full treatment. Use this table to decide what to update and who needs to act.
| Situation | Update the invitation | Message and RSVPs |
|---|
| Confirmed replacement date | Change the date and time under Details > Information, update the RSVP deadline, and add a short new-date note to the card and event summary | Notify attending guests, nonresponders, and guests who declined the old date. Ask everyone for a fresh yes or no by the new RSVP deadline |
| Venue change, same date | Update the venue name and address in the event details, and note the new location on the card or summary | Notify attending guests and nonresponders. No reconfirmation needed unless the new location changes someone's plans |
| Postponed, no new date yet | Add a clear postponement notice to the card and the event summary | Announce the postponement promptly to all guests, promise another update by a specific date, and reconfirm attendance once the new date exists |
One more option for a postponement: Greenvelope's guidance on handling a cancelled or postponed event suggests setting the RSVP capacity below the current number of attending guests, after which the RSVP page shows a message that the event is no longer accepting RSVPs. If you use this, restore the capacity once the new date is set, and check that guests can respond again before you ask for new RSVPs.
Update the Invitation First, Then Tell Your Guests
Treat these as two separate jobs. Editing the invitation changes what guests see whenever they open their link. Messaging is what makes them open it. The one exception is an urgent postponement: when the original date cannot proceed, send the notice first and finish the card edits after.
Start with the edits. In Greenvelope, the event date, time, and time zone live under Details > Information, as described in the help article on changing the event date and time zone. Update the venue fields the same way for a location change. When the date moves, also update the RSVP deadline itself under Details > RSVP Page > Basic RSVP Info, covered in the article on setting an RSVP deadline, so the invitation and your messages name the same reply-by date. Then add a short, visible note such as "New date: [New Date]" to the card and to the event summary at the top of the details page. Greenvelope's postponement guidance recommends exactly this kind of eye-catching notice, so anyone who opens the original invitation sees the change immediately.
After updating the invitation, send a separate change notice so guests know to check the new details, and ask them to update any calendar entries they created for the original date.
The simplest route is a message from the existing mailing: from the Send step, select the contacts you want to notify, then click Message, as described in the help article on sending a message via email or SMS. Match the channel to each guest's contact details rather than assuming an email reaches a guest who was invited by text, and for a change landing within a day or two, follow up directly by phone or text with anyone who might miss the notice. The alternative is a separate announcement to the same guest list, sent without the envelope per Greenvelope's postponement guidance so the information is in front of guests as easily as possible. Keep in mind that on Greenvelope, announcements do not collect RSVPs, so any reply request should point guests back to the original invitation or ask them to respond to your message directly.
Who Needs the Update
Send the change notice to guests who said yes and to guests who have not replied at all. Attending guests are planning around the old details, and nonresponders may be about to reply to a date that no longer exists.
When the date changes, also include guests who declined, and ask them for a fresh yes or no for the new date too. Someone who could not make the original evening may be free for the new one, and you can record the new response from the Track page. For an office party or client reception, loop in anyone coordinating on your behalf, such as an assistant replying for an executive.
Reconfirm Attendance for the New Date
A date change quietly turns every yes into a maybe, so reconfirm rather than assume. The simplest approach is a direct follow-up: message your attending guests and ask each one to reply with a fresh yes or no for the new date, even if they already accepted the original one. Opening the updated invitation does not confirm that a guest can attend the new date, so the reply is the confirmation. Depending on your event's settings and the RSVP deadline, guests may also be able to return to their invitation and update their response themselves, per Greenvelope's FAQ; either way, record any reply you receive by using the Track page to update a guest's RSVP whenever someone confirms by email, text, or in person.
If you keep the existing responses, the dashboard still shows each original yes. Keep a separate record of who has confirmed the new date, in a note or spreadsheet, and follow up directly with anyone still outstanding. Base your final vendor headcount on those confirmed replies for the new date, since the dashboard's attending total may still include guests who have not reconfirmed. Automated RSVP reminder emails will not help here: they go only to guests who have not responded, so they skip everyone whose original yes is still on the books.
Clearing responses back to pending is the other route, but it should not be your default. Clearing a guest's RSVP removes their recorded response data, including answers they submitted, and it is not available for guests who made a ticketed payment or who registered through a public registration page. It makes the most sense when the new date is far from the original and you genuinely want a fresh, formal RSVP from everyone eligible. A cleared guest counts as a nonresponder again, which puts them back in reach of the automated reminders you schedule next.
Reset Your Reminders
Review your scheduled reminders as soon as plans change, before the new date is settled: Greenvelope's postponement guidance recommends cancelling reminders for a cancelled or postponed event to avoid confusion. Open your scheduled reminders, described in the help article on scheduling RSVP and event reminders, review each one against the new plan, and delete anything built around the original date using the trash icon next to it.
Once the new date and the new RSVP deadline are both set, schedule replacements. RSVP reminder emails go to guests who have not responded, which makes them the right tool for first-time nonresponders and for any guests whose responses you deliberately cleared, with a friendly reminder about a week before the new deadline. Event reminders go to guests marked as attending, so use them for day-before or day-of details once the headcount is settled, and remember that an attending mark alone does not prove the guest reconfirmed the new date. Set the new RSVP deadline with a little room before any caterer or venue final-count date, so a late reply does not collide with a vendor commitment.
Copy-Ready Change Notices
Adapt these four messages to your event. Replace every bracketed placeholder, and keep the required guest action explicit.
Office Christmas Party Moved to a New Date
Subject: New date for the [Company Name] Christmas party
Hi everyone, our Christmas party originally planned for [Original Date] is moving to [New Date] at [Start Time], still at [Venue Name]. We know a date change is never convenient, and we appreciate you bearing with us. Please reply to this message with a yes or no for the new date by [RSVP Deadline], even if you already RSVP'd for the original one, so we can rebuild an accurate headcount. If you added the party to your calendar, please move the entry to [New Date]. The invitation at [Invitation Link] always shows the latest details.
Venue Changed, Date Unchanged
Subject: New location for our party on [Event Date]
Quick update: our party on [Event Date] has moved to [New Venue Name], [New Venue Address]. The date, time, and everything else stay the same, and we are sorry for any inconvenience this causes. If you already RSVP'd yes, there is no need to reply again, but if the new location means you can no longer attend, please reply to this message. If you have not responded yet, please RSVP at [Invitation Link] by [RSVP Deadline]. Either way, please update the location in any calendar entry you saved.
Weather Postponement, New Date Pending
Subject: Postponing our party on [Original Date]
With the weather forecast for [Original Date], we are postponing the party rather than asking anyone to travel in bad conditions. We have not set the new date yet, and no RSVP is needed yet. If you added the party to your calendar, please remove the entry or mark it postponed. We will send another update by [Follow-Up Date], and your invitation at [Invitation Link] will always show the latest details. Thank you for your patience while we sort out the new plan.
Reconfirmation Once the New Date Is Set
Subject: We have our new date, can you still make it?
Good news, the party is back on: [New Date] at [Start Time], [Venue Name]. Since plans may have shifted, please reply to this message with a yes or no by [RSVP Deadline], even if you accepted the original date, or RSVP at [Invitation Link] if this is your first reply. If you added the original date to your calendar, please update it to [New Date]. If the new date does not work, we completely understand. Just let us know either way.
Rescheduling Checklist
- Announce a postponement promptly when the original event cannot proceed, without waiting for replacement details or detailed card edits.
- As soon as possible after the notice, add a short postponement note to the card and the event summary; neither step waits for a replacement date.
- Review scheduled reminders right away and cancel anything built around the original date.
- Confirm the new date or venue with your vendors before announcing the replacement.
- Update the date, time, time zone, or venue under Details > Information, and note the new details on the card and the event summary.
- Once the new date is set, update the RSVP deadline under Details > RSVP Page > Basic RSVP Info, leaving room before any vendor final-count date, and if you closed RSVPs during the postponement, restore the capacity and check that guests can respond again.
- Send the change notice from the existing mailing by email or SMS to attending guests, nonresponders, and declined guests when the date changes.
- Ask guests who previously replied for a fresh yes or no for the new date, keep a separate record of confirmations, and record updates from the Track page.
- Schedule replacement RSVP and event reminders once the new date and RSVP deadline are confirmed.
- Ask guests to update any calendar entries they created for the original date.

Frequently Asked Questions
Should I send a separate message after changing the event date?
Yes. Editing the invitation changes what guests see when they open their link, but a direct change notice is what tells them to look. Message attending guests and nonresponders with the new details, include guests who declined when the date changes, ask everyone to update any calendar entries they created, and review your scheduled reminders at the same time.
Should I clear everyone's RSVP after rescheduling a Christmas party?
Usually not. Clearing a response removes the guest's recorded RSVP data, and it is not available for guests who paid for a ticket or registered through a public registration page. A direct reconfirmation message, with the host tracking confirmations and recording changes, is often all a date change needs. Cleared guests do become nonresponders again, which puts them back in reach of automated RSVP reminder emails.
What happens to reminders I scheduled before the party was rescheduled?
Review them right away. Greenvelope recommends cancelling reminders for a cancelled or postponed event, so delete anything built around the original plan as soon as it changes, then schedule replacements once the new date and RSVP deadline are confirmed.
