How it works
Simple by design
Step 1 — Create your event
Weddings, showers, graduations, reunions, holiday cards — set it up in minutes.
Step 2 — Share one link
Guests RSVP and share their address themselves. No app, no account, no back-and-forth.
Step 3 — Stay in touch
Send reminders, updates, and thank-yous right from your list — before, during, and after the event.
Step 4 — Keep it for next time
Every address becomes part of your permanent address book, ready for the next card, the next event, the next year.
Prefer paper? Scan an envelope or label and CardKeep captures the address instantly.
Most tools stop after the RSVP.
CardKeep doesn't. Send reminders, weather updates, parking instructions, registry changes, or a simple thank-you — all as individual texts, not a group chat.
