Greenvelope vs RevelPost

Greenvelope is a digital invitation and card service for planning events, managing guest lists, and tracking responses. Hosts can tailor fonts, colors, photos, layouts, envelopes, and background music, or upload their own artwork. Event tools include real-time RSVP tracking, custom questions, plus-one tracking, reminders, and seating charts. Invitations can go by email, SMS in supported countries, WhatsApp, Facebook Messenger, or a shareable link. Guests can respond without an account or app installation, and without seeing advertisements. Hosts can export guest lists, RSVP status, plus ones, meal selections, and custom-question responses as CSV or Excel files. Salesforce integration imports campaign contacts and syncs RSVP data to campaign-member statuses in real time. The trial permits sending a real invitation to up to 10 people without a credit card. Plans include a Single Mailing at $59, paid once for up to 60 people and an Annual Membership at $225 a year for unlimited mailings of up to 150 people each. Greenvelope is available on Android, iOS, and web, and provides an API.

RevelPost is a web invitation service for designing events and managing RSVPs, guest messages and reminders. Describe an event in one sentence and its AI creates invitation artwork in about 20 seconds. Names, dates and venue details remain editable typography, while dates are checked against a calendar and addresses against Google map data. Unusual times trigger confirmation prompts. Guest information can be extracted from spreadsheets, email threads, group chats or screenshots for review. RSVP pages collect party size, dietary needs, plus-ones and custom questions, with a host dashboard for responses, messaging and automatic reminders. Invitations can be delivered by email, SMS or link. Designing, refining and sharing an RSVP link are free without an account; emailing invitations and dashboard tracking require one. Free costs nothing for up to 10 guests. Pro costs $4.99 or $28.99 a year.
