Two-way texting and shared SMS inbox

Two-way texting software with a shared SMS inbox — every reply threaded to the contact.

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.

Two people side by side, one replying to a text message — the two-way SMS conversation that turns a broadcast into a real customer relationship

01 — Unified SMS inbox

Unified SMS inbox: one threaded conversation per contact across every campaign.

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.

  • One thread per contact across every campaign
  • Full message history, inbound and outbound
  • Read / unread filtering and search
  • Reply from desktop or mobile — same inbox

02 — Contact context

Contact profile and history visible next to every SMS thread.

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.

  • Contact profile alongside every thread
  • Tags, groups, and custom fields visible
  • Consent status and opt-in source attached to the contact
  • Internal notes to share context with teammates

03 — Automatic opt-out handling

STOP, HELP, and UNSUBSCRIBE handled automatically across the account.

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.

  • STOP / HELP / UNSUBSCRIBE honored platform-wide
  • Automatic confirmation reply on opt-out
  • Contact removed from every future campaign
  • Logged with timestamp for audit trail

Two-way texting use cases

Two-way texting use cases for political operations and customer-facing businesses.

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.

Political operations

Two-way texting for peer-to-peer voter outreach and donor stewardship.

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.

  • VOTERSQuestions about polling locations, ID rules, ballot drop-off
  • VOLUNTEERSShift swaps, confirmations, day-of coordination
  • DONORSThank-you replies, receipts, matching-gift clarifications
  • RAPIDRapid-response threads when a news cycle breaks
Business marketing

Two-way texting for customer service, appointment scheduling, and lead follow-up.

Faster than email, less painful than hold music — two-way handles the questions that come in after a broadcast.

  • SUPPORTOrder status, hours, store location questions
  • APPOINTMENTSReply C to confirm, R to reschedule
  • LEADSInbound inquiries from a flash sale or drop
  • FEEDBACKQuick-poll replies after a service or purchase

Two-way texting FAQ

Two-way texting FAQ — pricing, seats, and what's included.

How is two-way priced?

$12.49/mo as an add-on on Pay-as-you-go, Basic, and Pro. Included on Enterprise at no extra cost.

Do I need two-way enabled for STOP to work?

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.

Can a team share the inbox?

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.

Does inbound cost extra?

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.

What about outside quiet hours?

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.

What is two-way SMS?

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.

How is two-way texting different from group texting?

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.

Can multiple teammates share a two-way SMS inbox?

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.

Can I forward two-way replies to email or Slack?

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.
