Tag Paperless Post guests and message each group

1. Open the Tracking page of the sent invitation and click the Tags button at the top of the guest list, or the dropdown next to one guest.
2. Create a Guest Tag such as Lodging, then find each guest from your planner sheet in the list and add the tag, with the sheet open in another window.
3. Filter the list by the tag with the Guest sort option to check the group is complete.
4. Open Messages & Reminders, choose a template or Write your own, pick the statuses and the Guest Tag that should receive it, and write the subject and text.
5. Repeat the whole round for every group, and again whenever a guest moves from one group to another or a new guest joins.

Here are the out-of-town guests from my wedding planner sheet. Tag them "lodging" in Paperless Post, then send the ones who are attending the hotel room block link, and tell me who on the sheet is not on the guest list.

1. 01

   Match your list to the guest list

   The agent reads the names you give it, from a sheet, a note or a hotel booking export, and finds each one with list_guests by name, email or phone. Names it cannot match, or that match two guests, are shown to you before anything is tagged.

2. 02

   Tag the matched guests

   tag_guests adds the tag to all matched guest IDs in one call. Guest Tags are visible only to you and your co-hosts, so tagging reaches no one, and the agent can correct a wrong tag on the next run.

3. 03

   Choose who in the tag gets the message

   Before writing, the agent checks the statuses inside the tag. Hotel details usually go to Attending guests only, while a venue change goes to everyone who has not sent Regrets, and the agent asks you when the choice is not obvious.

4. 04

   Write a message that matches the invitation

   For a time or venue change the agent reads get_event first, so the broadcast repeats the date and address guests see on the Card. The text stays under 2,000 characters and carries a link instead of a file.

5. 05

   Send the broadcast or a private note

   send_message goes to the tag and statuses you approved. A guest who needs something different, such as a single room or an accessible shuttle, gets send_private_message instead, so the group broadcast stays general.

• Paperless Post Guest Tags belong to the All-Access feature set or a Paperless Pro subscription, and they show only to the host and co-hosts.
• Paperless Post Guest Tags can be added only after the invitation is sent, from the Tracking page, and they are included when the guest list is exported.
• A Paperless Post co-host starts with Track guests permission, which sees the list but cannot edit guests or send messages; the host has to grant those rights.
• Paperless Post broadcasts are limited to 2,000 characters with no attachments, and links in them may not be clickable on every device.
• Changing the date or venue in Paperless Post Event Details does not reset RSVPs already received; Paperless Post suggests a new invitation when a fresh round of replies is needed.

send_message and send_private_message ask for your OK by default. To run it on a schedule without you, switch confirmation off for those tools in your dashboard.
