How Popcorn captures SMS consent

This page documents Popcorn's two-step SMS consent flow for A2P 10DLC verification. Popcorn is a B2B SaaS platform; message recipients are contacts added to a Popcorn workspace by a customer business team member based on an existing business relationship.

Step 1: Business attestation in the Popcorn app

Consent capture begins inside the Popcorn app. A customer's team member opens the workspace contacts list and clicks “Add contact.” They enter the contact's name and phone number. Before they can submit the form, they must check a required box affirming consent:

“I represent and warrant that I have obtained prior express consent from this contact to receive SMS notifications about business operational events. This contact has an existing business relationship with our company and a reasonable expectation of receiving such communications.”

New contact

Add someone to the workspace contacts pool. Popcorn uses it to match inbound SMS and reach out if directed by you.

Step 2: Per-contact SMS double opt-in

Immediately after a contact is added, Popcorn sends a verification SMS. The contact must reply YES before Popcorn will send any further messages.

Popcorn → Contact
Hi Carlos! Justine at JL Interiors added you to receive delivery reminders via Popcorn. Reply YES to confirm or STOP to opt out. Msg & data rates may apply.
Carlos → Popcorn
YES
Popcorn → Contact
You're confirmed! You'll now receive delivery reminders from JL Interiors via Popcorn. Reply STOP at any time to opt out, or HELP for help.

Until the contact replies YES, Popcorn sends no operational messages (reminders, check-ins, or weekly summaries) to that number.

Opt-out

Popcorn honors the keywords STOP, END, QUIT, UNSUBSCRIBE, and CANCEL automatically at the carrier level, with the standard auto-reply confirmation. Once a contact opts out, Popcorn sends no further messages to that number through the workspace.
