Two-way texting and shared SMS inbox
When a voter asks where to vote, a customer asks about store hours, or a donor replies to a thank-you message, the inbound text lands in one shared SMS inbox attached to that contact, with the full conversation history and every tag visible alongside it. Two-way texting is a $12.49/month add-on and is included on the Enterprise plan.
01 | Unified SMS inbox
A voter who replied to three different GOTV sends lives in one conversation, with timestamps, which campaign each message came from, and any tags attached. No hunting across inboxes, no reconciling contexts.
02: Contact context
The contact profile sits beside the thread. Tags, groups, custom fields, DNC status, opt-in source, and notes: all visible while you're typing the reply. Operators don't guess, and teammates picking up a conversation don't start cold.
03: Automatic opt-out handling
When someone replies STOP, HELP, or UNSUBSCRIBE (with or without the two-way add-on), the platform honors it immediately. The contact drops out of every future send, confirmation goes back, and the audit trail logs it. You never maintain a manual opt-out list.
Two-way texting use cases
A broadcast is one-to-many; a two-way SMS conversation is one-to-one. Two-way texting is the right tool whenever the customer's reply matters as much as your outbound message.
When a voter asks a question, a canvasser asks for a shift swap, or a donor wants a receipt, a live thread beats a second broadcast.
Faster than email, less painful than hold music. Two-way handles the questions that come in after a broadcast.

Two-way texting FAQ
$12.49/mo as an add-on on Pay-as-you-go, Basic, and Pro. Included on Enterprise at no extra cost.
No. STOP, HELP, and UNSUBSCRIBE are handled platform-wide, even without the two-way add-on. The add-on gives you the inbox and the ability to reply to regular messages.
Yes. Included seats per plan: 1 on PAYG and Basic, 2 on Pro, 5 on Enterprise. Additional seats are $25/user. Everyone on the account sees the same threads.
Outbound SMS counts against your plan (or bills per-segment on PAYG). Inbound messages don't consume bundled SMS. The add-on fee covers inbox infrastructure.
If someone texts you at 11 p.m., the reply you write still respects the recipient's local quiet-hours window. It queues and delivers when it's allowed.
Two-way SMS means the same phone number that sends your campaigns also receives replies, and those replies are routed into a threaded inbox tied to the contact who sent them. The contrast is one-way (broadcast-only) SMS, where inbound texts are dropped or sent to a black-hole address. Two-way is what lets a customer ask "what time do you close?" and reach a human, not a void.
Group texting (iMessage-style "everyone replies to everyone") is built for small social groups. It doesn't scale, has no consent infrastructure, and isn't TCPA-safe for marketing. Two-way SMS at the business level is one-to-many on the outbound side (each recipient gets a private thread) and one-to-one on the inbound side (their reply lands only in your inbox, not a group). It's the difference between a Slack channel and a personal DM.
Yes. The inbox is account-wide: every seat on your account sees the same threads, the same contact history, and the same tags. Pro includes 2 seats, Enterprise includes 5, and extra seats are $25/user. Assignment, read/unread state, and per-thread notes are handled in the UI; multiple people can answer different threads at the same time without stepping on each other.
The inbox is the primary surface, but inbound notifications can route to a designated email per account, and webhook export is on the roadmap. Most teams just leave the inbox open on a second monitor or check it the way they check email.
Start sending
Take the toll-free quick-start: open an account, add the two-way SMS inbox add-on, and inbound replies land in a threaded inbox as soon as verification clears, usually about three business days. For teams handling consistent inbound volume, 10DLC carrier registration is the recommended path for long-term deliverability and runs in parallel while you're already sending.
