Which Online Invitation Platforms Let You Control Plus-Ones and Household RSVPs?

Greenvelope, Paperless Post, RSVPify, Zola, The Knot, Joy, Evite, and Partiful all let you control plus-ones in some form, and they split on the detail that decides whether your headcount is right: whether a known couple or family can be grouped under one invitation so one person can record a separate attendance response for each named member. On Greenvelope, a plus-one allowance is set per contact, a couple or family is grouped by name under one primary contact and shares one invitation link, and the person who completes the shared RSVP records a separate attendance response for each named member. Paperless Post, RSVPify, Zola, The Knot, and Joy also document named household groups with their own rules. Evite and Partiful document a plus-one cap per event, and their documentation reviewed does not establish named household grouping.

This comparison is published by Greenvelope and is based on provider documentation reviewed on November 4, 2026, not hands-on testing; confirm current details with each platform before you commit. If you are still deciding who gets a plus-one at all, that is an etiquette question: see our wedding plus-one etiquette guide or our holiday party plus-one etiquette guide. This page is about the mechanics that enforce whatever you decide.

At a Glance

• This guide's recommendation: Greenvelope, whose Plus 1 allowance is set contact by contact (or for several contacts at once), whose grouped couples and families share one invitation link with a reply recorded for each named member, and whose plus-one settings can collect or require the extra guest's name and email
• Per-guest party sizes with named groups: Paperless Post sets a Total Invited count per invitation and groups couples and families by name; RSVPify sets additional guests allowed per invitee, including Unlimited, and links group members with a Group ID
• Closed wedding guest lists: Zola and The Knot (with its invited-only setting) only accept RSVPs from names already on the list, and Zola lists at most two adults per family entry
• Flexible wedding lists: Joy lets a plus-one be named or left blank for the guest to fill in, groups guests into parties, and can let any guest add plus-ones
• One cap for everyone: Evite's additional-guests limit and Partiful's plus-one limit apply across the whole guest list, with no documented per-guest allowance or named household grouping
• The deciding detail is whether an allowance is permission or a count: an unused plus-one is not an attendee, and on Greenvelope one person can submit a household RSVP with a separate attendance response for each named guest

What Controlling Plus-Ones and Household RSVPs Actually Covers

Four different controls travel under this one question, and a platform can offer one without the others.

The first is a plus-one allowance: permission for a particular invitee to bring a guest whose name you may not know yet. The second is a household or party group: a couple or family you already know by name, invited together so that one person can reply for everyone and each person still gets a recorded answer. The third is name collection: whether the platform asks for the extra guest's name and contact details, and whether you can require them. The fourth is an attendance cap: a limit on how many people can say yes to the event at all, which is a separate setting from any allowance.

Two details decide how useful the controls are. One is granularity: whether the allowance is set per guest or once for the whole list. The other is what the host sees afterward: a count per invitation, or a reply per named person. For the related question of how many people can attend at all, see our guide to the best online invitation platforms with RSVP limits and guest caps.

Plus-One and Household RSVP Controls Compared Across Eight Platforms

Greenvelope and the seven other platforms below are compared from provider documentation reviewed on November 4, 2026. "Not described" means the provider's documentation reviewed for this guide does not cover it, not that the feature is unavailable.

How Plus-Ones and Household RSVPs Work on Greenvelope

On Greenvelope, plus-ones and households are two separate controls, and the Plus 1 Policy documentation says so: it is not the feature used to link couples or family members. A plus-one allowance is permission, not an attendance count. A grouped household is a list of named people who share one invitation.

Set Plus-One Allowances

The plus-one allowance lives in two places. The default for new contacts is set under Details, RSVP Page, Plus 1 Policy, where Manage Plus 1 Settings expands three options: the default Plus 1 allowance, whether an "and Guest" line appears on the front of the envelope, and which information to collect from a plus-one, such as first name, last name, and email, which you can collect or require. Each contact can then differ from the default: on the Send step, click the contact and change the Allow +1? menu, or tick several contacts and use the Edit link at the top of the list to update them together, as the Manage Plus 1s article describes. That is how the college roommate gets a plus-one while the coworker table stays as invited.

Add Named Couples and Families

A couple or family is added on the Send step, following Group Couples and Families Together: Add Contacts, New Contact, then Couple or Family, choose the group size, and enter each member's name. An email address or phone number is optional for the other household members; include one and that member receives the card as well, leave it out and the household still replies from the one shared link. A Couple/Family Greeting, such as The Alvarez Family, can replace the list of names on the front of the envelope. The person completing the shared RSVP records a separate attendance response for each named member, so a family of four comes back as four answers. Survey questions appear on the RSVP page after a guest selects an RSVP response. No guest needs a Greenvelope account to reply.

Review Attendance and Capacity

Three more settings sit alongside these. Maximum capacity, under Details, RSVP Page, Basic RSVP Info, limits attendance by capping how many guests can respond yes, and it is separate from both the allowance and the size of list you buy. Survey questions can be limited to a contact tag, so you can show a question to selected contacts only. And a reply a guest gives you in person can be recorded by hand from the Track page. RSVP functionality is included only in invitation mailings; save the dates, announcements, and cards do not carry the RSVP flow.

Invitations are sent by email or by text message in supported countries; paid accounts start with 500 text messages, with more available to purchase. Single mailings start at $19 for a guest list of up to 20 people, with pricing based on list size and no subscription required; every person listed counts toward the tier, household members included, whether or not they reply. A trial send to up to 10 people needs no credit card. For the full picture of what a mailing costs, see how much Greenvelope costs.

How the Other Platforms Handle It

Compare these alternatives to Greenvelope by their documented plus-one and household RSVP settings; each is described on its own terms, from its own documentation.

Paperless Post

Paperless Post offers two routes. For guests whose companions you already know, Add Couple/Family on the Invite Guests page creates a group with a group name, each guest's name, and a phone number or email; group members see the rest of their group at the top of the invitation and can reply for one or all of them, and the tracking page lists them individually under the group name. For plus-ones you cannot name yet, Allow guests to bring additional guests sets a Total Invited count that includes the invitee, so a +1 means a count of 2. The count can be a blanket default for the list or adjusted per invitation on the Invite Guests page, and a spreadsheet upload can carry a Total Invited column. A guest with plus-ones picks their party size up to your maximum and can add names and contacts for the extra guests. One interaction to know: with the blanket setting on, a pre-defined couple or family group can add further guests up to 10 people in total, so Paperless Post suggests setting Total Invited per guest instead when you want groups fixed. Hosts can adjust a guest's headcount and status by hand from the Tracking page. Paperless Post offers a no-charge route for free designs without paid elements to the first 50 direct recipients. Paid event sending uses Coins per recipient, resending to the same guest is free, and Paperless Pro uses annual guest-count pricing without Coins; check its pricing page for how a grouped invitation is counted.

RSVPify

RSVPify sets additional guests allowed per invitee: none, up to a number you choose, or Unlimited. The setting is entered when you add an invitee by hand, carried in a column when you import a spreadsheet, and changed later under Invite List, Invitees, including a bulk Edit additional guests allowed action. A Group ID in the import links guests who reply as one group, such as a couple or family, with one email address per group, so the primary guest is listed first and receives the invitation; whether a group can submit mixed answers, one member accepting and another declining, is not described in the documentation reviewed. When a guest says they are bringing a plus-one, they are prompted for that person's name. These controls apply to invite-only private events; RSVPify's personal plans run from Free to paid tiers by guest count, with business plans priced separately.

Zola

Zola runs a closed guest list: guests must be on the list to RSVP, and they cannot add their own plus-ones or additional guests in the RSVP flow if you have not set one up for them. A plus-one is added to a guest entry with Add Plus One, and a Name Unknown box lets the guest fill in the name when they RSVP. A couple or family entry can list two adults; other members, including adult relatives, are added as children, and guests listed that way are not told so. Guests grouped as a couple or family can RSVP on behalf of everyone in their party, giving attendance and meal answers for the events each is invited to. Guests must be marked Definitely Invited to an event, and each event has its own Let guests RSVP on website toggle. Zola's guest list, website, and RSVP tools are free as part of its wedding planning suite.

The Knot

The Knot's Guest List Manager builds parties: open a guest and add a guest to this party, with a Name unknown option, and the list can be sorted by party size. What guests can change depends on the RSVP privacy setting. Guests cannot add extra guests to their party when RSVPs are restricted to invited guests, the setting The Knot recommends, and names must be entered as the host has them; whether a guest can fill in a companion already reserved as Name unknown is not described in the documentation reviewed. With RSVPs open to anyone, guests can add as many additional +1s as they choose. The Knot's guest list and wedding website tools are free.

Joy

Joy is a wedding-focused platform whose guest list has a plus ones column: click a guest's number and choose how many to add. A plus-one can be named or left blank, in which case the guest enters the name when they RSVP and it appears on your guest list; invitations address the group by name followed by "and guest." Selecting guests and clicking Create Party groups them so one person can respond for the whole party, choosing Respond next to each guest and saving an answer for each; without a group, each guest can only respond for themselves. Two optional settings widen the door: Allow Any Guest to Add +1s asks guests for their party size, and Unlimited Plus Ones allows up to 20 per guest. Joy's website, planning tools, and Basic Digital Cards are free, with Premium Digital Cards and Messaging Plus as paid options.

Evite

Evite's Limit Per Guest setting is under Manage Event, RSVP Options: Max number of additional guests per RSVP, up to +9. Evite's documentation states that the limit applies to the entire guest list and that different limits cannot be set for different guests, and that it is separate from the Maximum Capacity setting that closes RSVPs at a total headcount. Guests who open the invitation enter a guest count after choosing their answer, with an adults and children split when the host turns it on; if there is no field, the host is tracking one seat per guest. Named couple or family grouping is not described in the documentation reviewed.

Partiful

Partiful lets hosts limit the number of +1s each guest may bring from Event Settings; the default allows one, and hosts can set it anywhere from 0 to 9. The same settings area holds a maximum capacity with an automatic waitlist. RSVPs run through a Partiful account with a phone login code, and the documentation reviewed does not describe named household grouping or collecting a plus-one's name. Partiful's core features are free, with optional paid features.

One 60th Birthday Dinner, 52 Named Guests and Six Plus-Ones: An Illustrative Example

On Greenvelope, Dana prepares invitations for her father's 60th birthday dinner at a restaurant on Saturday, March 13, 2027. The private room seats 60, and the restaurant wants a final count on Monday, March 8. Dana builds the list using Fancy Dinner by Claudia Owen and sends it by email on Saturday, February 13, four weeks ahead, which sits inside the 3 to 4 week window for most parties, so the reminder emails later will reach every contact. Her list has 31 contacts: 14 couple or family contacts holding 35 named people, and 17 individual contacts. Six of the individuals, the single friends who may bring a date, get Allow +1? set to one; the other 11 stay at none. With 52 people listed, the mailing is the up-to-60 tier at $59.

• Default settings: the Plus 1 Policy default is none, the "and Guest" envelope line is on only for the six contacts with an allowance, and plus-one settings are configured to collect the extra guest's first and last name. Maximum capacity is set to 58 affirmative RSVPs, leaving two seats for Dana and her husband.
• Thursday, February 25: a scheduled RSVP reminder email goes to every contact who has not responded, one week before the deadline.
• Thursday, March 4, the RSVP deadline: 12 of the 14 households have replied, recording 25 yes and 4 no across their 29 named members. 15 of the 17 individuals have replied, 12 yes and 3 no, and four of the six plus-one holders added a named guest. Dana sends a brief final note to the four contacts still missing.
• Friday, March 5: Dana sends one personal follow-up to each contact still missing, asking for a reply by Saturday, March 6. The two households record three yes and three no responses, and the two individuals record one yes and one no.
• Monday, March 8: the count to the restaurant is 47: 41 named guests who said yes, 4 recorded plus-ones, and the two hosts. Dana exports the guest list and RSVPs to Excel or CSV and checks the file before sending the restaurant its final count.

The dates and numbers are illustrative. Two things made the count easy: a grouped family came back as separate yes and no answers rather than one ambiguous reply, and the two unused plus-one allowances never became attendees, because an allowance is permission, not a headcount.

Which Platform Fits Your Guest List

• You know most of your guests by household and want a reply per person: Greenvelope groups each couple or family by name under one link with a response recorded per member; Paperless Post, RSVPify, Zola, The Knot, and Joy also document named groups.
• Some guests get a plus-one and others do not: Greenvelope, Paperless Post, RSVPify, Zola, The Knot, and Joy all set the allowance per guest or per party. Evite and Partiful apply one limit to everyone.
• You want the extra guest's name and email on file: Greenvelope's plus-one settings can collect or require them; Paperless Post lets guests add names and contacts; RSVPify and Joy prompt for the name; Zola takes the name when a guest fills in a plus-one left as Name Unknown.
• You want a closed list where nobody can add themselves: Zola, and The Knot with RSVPs limited to invited guests. On Greenvelope, turning off Enable Sharing disables the public registration link and stops further registrations; personalized invitation links are associated with invited guests or households, but they are not access control.
• You want guests to size their own party with little setup: Evite's headcount field, Partiful's +1 limit, Paperless Post's blanket Total Invited, or Joy's Allow Any Guest to Add +1s.
• Your room has a hard limit: set an attendance cap as well as the allowances. Greenvelope's Maximum capacity, Evite's Maximum Capacity, and Partiful's capacity with a waitlist are separate from any plus-one setting.

Frequently Asked Questions

Which online invitation platforms let me control plus-ones and household RSVPs?

Greenvelope sets a plus-one allowance per contact and groups couples and families by name under one invitation link, with a separate attendance response recorded for each named member. Paperless Post, RSVPify, Zola, The Knot, and Joy also document plus-one controls and named household or party groups, with allowance rules that vary by platform. Evite and Partiful document one plus-one limit for the whole guest list, and their documentation reviewed does not describe named household grouping.

How do I give some guests a plus-one and not others on Greenvelope?

On Greenvelope, set the default under Details, RSVP Page, Plus 1 Policy, then change individual contacts on the Send step: click a contact and edit the Allow +1? menu, or tick several contacts and use the Edit link to update them together. The allowance is permission for that contact, and it does not link couples or families, which are grouped separately.

Can a family RSVP from one invitation and still give me a reply for each person?

On Greenvelope, yes. Add the family on the Send step as a Couple or Family contact with each member named; they share one invitation link, and the person completing the RSVP records a separate attendance response for each named member, and survey questions appear on the RSVP page after a guest selects a response. Paperless Post, Zola, and Joy also document one person replying for a whole group, so check how each one records the individual answers.

Can I collect the name of a guest's plus-one?

On Greenvelope, yes. Manage Plus 1 Settings on the RSVP page lets you choose which information to collect from a plus-one, such as first name, last name, and email, and whether to require it. Paperless Post lets guests add names and contacts for additional guests, RSVPify and Joy prompt for the plus-one's name at RSVP, and Zola takes the name when a guest fills in a plus-one left as Name Unknown.

Does a plus-one allowance count toward my headcount?

No. An allowance is permission for a guest to bring someone, not an attendance count, so an unused allowance never becomes an attendee. Count the guests who have actually confirmed, including any additional guests recorded in their RSVPs, and treat that as your expected headcount based on RSVPs.

Is a plus-one limit the same as a guest cap?

No, and the platforms keep them apart. A plus-one limit controls how many extra people one invitation may bring. A capacity setting limits how many people can say yes to the event at all. On Greenvelope, Maximum capacity caps affirmative RSVPs and is separate from the Plus 1 allowance and from the guest-count tier you buy, which covers everyone on the list whether or not they reply.

What happens if a guest tells me their plus-one in person instead of on the invitation?

On Greenvelope, record it yourself: the host can manually update a guest's RSVP from the Track page, so a verbal reply is counted with everyone else's. Paperless Post also lets hosts adjust a guest's headcount and status from its Tracking page, and RSVPify lets hosts submit an RSVP on a guest's behalf.
