Best Online Invitation Platforms With RSVP Limits and Guest Caps

Greenvelope, RSVPify, Partiful, Evite, and Luma all let a host put a hard number on an event, and Greenvelope is a strong fit when you want a designed invitation, a named guest list, and a documented capacity setting: its Maximum capacity setting limits attendance by capping how many guests can respond yes to an invitation mailing. If overflow should queue on a waitlist, or individual ticket tiers need their own limits, one of the alternatives below may fit better, and this guide shows exactly where.

This page covers one decision: choosing an invitation platform when your venue, caterer, or budget holds a fixed number of people. For a broader comparison of design, pricing, and guest experience, start with our roundup of the best digital invitation platforms; for how online responses work in general, see the online RSVP guide.

At a Glance

• Separate three numbers before you choose anything: how many people you may invite, how many may attend, and how many seats one invitation can claim
• Pick Greenvelope for a designed invitation to a named list with a documented attendance cap, Partiful or Luma when overflow should queue on a waitlist, and RSVPify when the event and its individual ticket tiers need their own limits
• Check the fine print first: some capacity controls sit on paid tiers, waitlist admission is automatic on some platforms and host-approved on others, and Evite’s capacity control belongs to its Invitations product, not Event Pages
• Use the worked 40-seat dinner, the pre-send checklist, and the FAQs to verify every setting before the invitation goes out

How We Checked These Platforms

Greenvelope publishes this guide, so read the recommendation with that in mind. Every capability claim comes from each platform’s own current product, help, or pricing pages, reviewed on October 16, 2026, and linked throughout. Where a page does not cover a behavior, we say it is not described in the documentation reviewed rather than treating it as absent, and we did not run live tests at any platform’s capacity boundary.

Six Capacity Controls That Sound Alike and Are Not

Most capacity surprises happen because a host verified one of these numbers and assumed it covered the other five:

• An invite limit caps how many people go on the guest list at all. Evite allows up to 750 guests per invitation, or 2,500 with the Evite Pro annual subscription. On Greenvelope, the purchased guest-count tier plays this role: it covers everyone on the mailing list, reply or no reply, with each listed person counting individually, household members included.
• An attendance cap limits how many people can end up coming. Greenvelope’s Maximum capacity setting caps how many guests can respond yes; the other four platforms document event capacity controls of their own, profiled below.
• A per-invitation allowance controls how many seats one invitation can claim. Greenvelope’s Plus 1 Policy sets an allowance per individual contact. Evite’s Limit Per Guest setting applies one allowance, up to 9 additional guests per RSVP, across the entire guest list, and its documentation states different limits cannot be set for different guests. Partiful caps how many plus-ones guests may bring, with the default set to one.
• An RSVP access restriction controls who may respond at all. Greenvelope sends to a defined guest list through personalized invitation links that identify each invited guest or household for tracking, and a public shareable link can also be enabled; sharing one does not, by itself, identify everyone who received it or show who has not responded. RSVPify can restrict registration to listed invitees when the invite list’s security is set to invite-only, with public registration remaining an option, and Partiful documents Guest Approval, where only guests the host approves get access.
• A waitlist covers two separate questions: how guests join the queue, and how they get in. On Partiful, the host enables the waitlist, guests can join it after capacity is reached, and promotion is automatic. On Luma, new registrations join the queue automatically once its waitlist is enabled, but admission needs host approval. RSVPify’s documented method is a separate, host-built waitlist event, and Greenvelope’s documentation does not describe a waitlist, so there it is the host’s own follow-up list.
• Per-ticket inventory limits individual choices rather than the whole event. RSVPify documents limited quantities on individual ticket tiers alongside its event-wide limit; finer per-option limits on RSVP choices appear only in its next-generation Enterprise documentation, so do not assume them on other plans. Luma documents per-ticket-type capacity, though its waitlist is event-wide. Per-ticket inventory is not described in the Greenvelope documentation reviewed.

Capacity Controls Side by Side

Greenvelope: A Designed Invitation With a Documented Attendance Cap

Greenvelope treats a capacity-limited event as three separate numbers, each set deliberately. The first is the attendance cap: the Maximum capacity setting, a toggle under Details, then RSVP Page, then Basic RSVP Info on any invitation mailing, which limits attendance by capping how many guests can respond yes. The second is the per-invitation allowance: the Plus 1 Policy, which sets how many additional guests each individual contact may bring, editable one contact at a time or in bulk, with the option to collect or require the plus-one’s information. The third is the purchased guest-count tier, a purchase limit rather than an attendance control: it covers everyone on the mailing list whether or not they reply.

The documentation also covers the full-event case: the Closing RSVPs article describes using the same Maximum capacity setting to stop accepting new RSVPs when the event can no longer take guests. What a later guest sees at the cap, and what happens after a cancellation, is not described in the documentation reviewed, so the practical habit for a tight room is watching the tracking dashboard and treating any freed seat as a personal follow-up. Personalized invitation links identify each invited guest or household, so for named contacts tracked that way the host can see exactly who has not answered, send or schedule RSVP reminder emails to them, and work from an expected headcount based on RSVPs rather than a certainty. Greenvelope also documents open registration through a public shareable link and, on business accounts, ticket sales and donations on the RSVP page; what it does not describe is a waitlist or per-ticket inventory counts. Consider Partiful for automatic waitlist promotion on non-ticketed RSVP events, Luma for waitlisting with host-approved admission, or RSVPify for event-wide and ticket-tier limits. Single mailings start at $19 for a guest list of up to 20 people, with pricing based on list size and no subscription required; the pricing guide covers the tiers.

RSVPify: Event and Ticket-Tier Limits, Gated by Plan

RSVPify documents an Event Capacity Limit that closes the event to new registrations once reached, plus limited quantities on individual ticket tiers, and can restrict registration to listed invitees when the invite list’s security is set to invite-only; public registration remains an option. Finer-grained controls, such as guest limits on individual RSVP options, appear in RSVPify’s next-generation Enterprise documentation, so do not count on them outside that product. Its documented waitlist setup uses a separate waitlist event the host builds and points guests to after closing the main event; automatic promotion from it is not described in the documentation reviewed. Plan requirements depend on the event type. On non-ticketed personal plans, the no-cost plan covers up to 100 guests with basic RSVP features, capacity limits are listed with the Platinum plan, and custom additional-guest counts beyond a single unnamed plus-one sit on business plans. Events selling tickets receive Professional features with no subscription, including custom additional-guest allowances, with a per-ticket fee plus payment-processing fees. The tradeoff to weigh is that the richest controls arrive through a paid plan, a ticketed event, or the Enterprise product.

Partiful: A Host-Enabled Automatic Waitlist at No Cost

Partiful lets a host set a maximum capacity under Event Settings and enable an automatic waitlist. The two work together but are separate choices: with the waitlist turned off, no one can RSVP after the cap is reached. When the host enables the waitlist, guests can join it after capacity is reached, and when a spot opens, Partiful automatically adds the next waitlisted guest and notifies them by text. That workflow covers non-ticketed RSVP events: Partiful’s own ticketing comparison lists waitlists on paid tickets as unavailable. Hosts can cap how many plus-ones guests may bring, with the default set to one, and guest control runs deeper than the party aesthetic suggests: events are private by default, and Guest Approval limits access to guests the host approves. Its core event planning tools are available at no cost, with optional premium invitation designs and a fee on ticket purchases. The fit question is presentation: Partiful’s social, party-forward style is an editorial preference call for a formal dinner or client event, built around shared links rather than a formally addressed card.

Evite: A Capacity Field on Evite Invitations

Evite documents a straightforward control, with one product distinction that decides whether you have it at all: the Set an event capacity field belongs to Evite Invitations, reached through My Invitations, then Manage Event, then RSVP Options, while Evite’s Event Pages product lists no maximum event capacity in its RSVP settings. Hosts who need the cap should build an Invitation. Once the RSVP count meets the number, additional guests who try to RSVP see a message that the guest list is full, and the host can raise or remove the limit at any time. Evite states it places no set limit on how many guests can RSVP apart from the capacity the host sets, while the guest list allows up to 750 people per invitation, or 2,500 with the Evite Pro annual subscription. Two limitations to check: the Limit Per Guest setting allows up to 9 additional guests per RSVP, applied across the entire guest list with no way to set different limits for different guests, and no waitlist is described in the documentation reviewed, so overflow is the host’s own follow-up.

Luma: Event-Wide Capacity With an Approval-Based Waitlist

Luma approaches the problem from the events-and-registration side. Hosts set an event capacity, which on its own closes registration when the event is full; with the Over-Capacity Waitlist enabled, new registrations instead join the queue automatically. Only approved guests count toward the limit, and admission from the waitlist requires host approval, so a cancellation does not automatically promote anyone. The waitlist covers paid tickets as well: guests authorize payment when they join and are charged only if approved, with crypto-priced tickets excluded. Ticket-type capacity is a separate number that marks a ticket sold out, and the waitlist is event-wide rather than per ticket type, so a single sold-out tier does not get its own queue while other tiers remain available. When group registration is enabled, Luma’s capacity documentation states that each ticket in the registration counts toward event capacity. The tradeoff is presentation: Luma reads as a registration page rather than an invitation, which suits meetups and community events more than an occasion where a designed card addressed to a guest carries the moment.

A 40-Seat Dinner With 60 Invitees, Worked Through

Here is a purely hypothetical setup to make the controls concrete: a dinner in a room with 40 available guest seats and 60 invitees, counting named partners and household members. Sending one invitation to all 60 only works as a reservation-style evening, where the wording tells every invitee up front that seating is limited to 40 and places go to the first confirmed replies. When each personal invitation should imply a reserved place, stagger instead: invite a list at or under 40 and send further invitations as declines come in. Either way, the three Greenvelope numbers come apart cleanly. The guest-count tier must cover all 60 names, because every person on the mailing list counts toward the tier whether or not they reply. The Maximum capacity setting is 40, the available guest seats. And the additional-guest allowance is deliberate: zero plus-ones, with partners added as named household members instead, so every expected attendee is identifiable by name and the person completing a shared household RSVP records a separate attendance response for each named guest. One check before relying on this setup: confirm how named household members count toward the Maximum capacity setting, since the counting basis is not spelled out in the documentation.

Timing works backward from the venue or caterer’s final-count deadline: set the RSVP deadline far enough ahead of it to chase stragglers, and send or schedule reminder emails to guests who have not replied. As yes responses approach 40, the host’s job shifts to tracking, since the documentation covers the cap itself rather than the moment it is reached. If someone cancels, record the cancellation on the tracking page, then check the live count and confirm how the platform handles reopened availability before offering the place, since other invitees may still be able to respond while you wait for an answer; record the replacement guest’s attendance once they confirm.

The Pre-Send Capacity Checklist

• Set the attendance cap to the available guest places, not the invite count.
• Choose a plan or mailing tier that covers everyone on the list, since invite limits and attendance caps are different numbers.
• Set additional-guest allowances deliberately, per contact where the platform supports it, and add known partners as named guests instead of unnamed extras.
• Decide the overflow plan before the first yes arrives: where a waitlist is documented, check whether admission is automatic or needs your approval; where none is described, keep a manual follow-up list.
• Send yourself a test invitation to confirm the guest experience; a test shows the flow you built, not what happens at the capacity boundary.
• Work backward from your caterer’s or venue’s final-count date to set the RSVP deadline, and send or schedule reminder emails to guests who have not replied.
• Recheck the cap after any guest-list change, because adding invitees never adds seats to the room.

If a designed invitation with a named guest list and a documented attendance cap is the combination you need, browse Greenvelope’s designs and set the Maximum capacity on your mailing before it goes out.

Frequently Asked Questions

Which online invitation platforms let you limit how many guests can RSVP?

Greenvelope, RSVPify, Partiful, Evite, and Luma each document an event capacity control. On Greenvelope, the Maximum capacity setting on an invitation mailing limits attendance by capping how many guests can respond yes. RSVPify closes registrations at its Event Capacity Limit, Partiful blocks RSVPs at its cap or lets guests join a waitlist the host enables, Evite cuts off responses at the event capacity field on Evite Invitations, and Luma closes registration at capacity or routes new registrations to a host-approved waitlist when its Over-Capacity Waitlist is enabled.

Does Greenvelope have a maximum capacity setting for RSVPs?

Yes. On any Greenvelope invitation mailing, the Maximum capacity toggle sits under Details, then RSVP Page, then Basic RSVP Info. It limits attendance by capping how many guests can respond yes, and the same setting is documented as the way to stop accepting new RSVPs when the event is full. RSVP features come with invitation mailings, so save the dates, announcements, and cards do not accept RSVPs.

What is the difference between a guest list limit and an RSVP capacity limit?

A guest list limit caps how many people you can invite, like Evite’s 750-guest allowance per invitation or Greenvelope’s purchased guest-count tier, which covers everyone on the mailing list whether or not they reply. An RSVP capacity limit caps how many of those invitees can end up attending. A capacity-limited event needs both numbers set on purpose, because each one limits a different thing.

Do plus-ones count against an RSVP capacity limit?

Keep the planning rule separate from product behavior. The planning rule: count every guest confirmed attending, including companions recorded in RSVPs, in your working total, and remember that an unused additional-guest allowance is not a confirmed attendee. On enforcement, the documentation gives partial answers: Evite describes its capacity limit in terms of the total RSVP headcount, and Luma counts each ticket in a group registration toward event capacity. Where a platform does not explain how households or companions count toward its cap, confirm that before relying on it. The allowances themselves differ too: Greenvelope sets one per contact, Evite applies one allowance of up to 9 across the whole guest list, and Partiful defaults each guest to one plus-one.

Which platforms offer waitlists, and how are guests admitted?

Waitlists differ on entry and on admission. On Partiful, the host enables the waitlist for a non-ticketed RSVP event, guests can join it after capacity is reached, and the next waitlisted guest is added automatically and notified by text when a spot opens. On Luma, entry is automatic once the Over-Capacity Waitlist is on, but admission requires host approval, and a cancellation does not automatically promote anyone. RSVPify documents a separate waitlist event the host builds and manages. Greenvelope and Evite describe no waitlist in the documentation reviewed, so overflow there is a follow-up list the host runs personally.

Does an RSVP capacity limit stop extra people from showing up?

No. A capacity setting limits the yes responses an event collects online, which keeps the plan and the headcount in check, but it does not physically prevent anyone from arriving. For events where the door matters, pair the cap with a named guest list, clear wording about who the invitation covers, and a point person who has the final list on the day.
