SMS automation software
The text-message automation an operator actually uses: queue tomorrow's send tonight, configure "HOURS" to auto-reply with your business hours, and let the platform hold each message until the recipient's local quiet-hours window opens. There's nothing to draw on a whiteboard and no decision-tree flowchart to maintain.
01 — Scheduled campaigns
Build the message today, pick a date and time, and walk away. The send fires on schedule and respects recipient time zones — a 10 a.m. send doesn't arrive at 7 a.m. for someone two zones west.
02 — Keywords and auto-response
Configure keywords like HOURS, INFO, VOTE, DONATE, or RSVP. When a contact texts one, the platform replies with whatever you set — and optionally tags or adds them to a list. Add-on at $20/mo.
03 — Always-on automation
STOP, HELP, and UNSUBSCRIBE are honored platform-wide. Quiet-hours windows are enforced per recipient time zone. Opt-outs filter at send time. You don't turn these on — they're how the platform sends.
How SMS automation runs
The four pieces of automation most operators actually need — no branching trigger trees and no flowchart canvas to learn first.
Build now, send later. Days or weeks ahead. Cancel up until it fires.
Map a word to a response. Optionally tag the sender or add them to a list.
STOP / HELP / UNSUBSCRIBE honored immediately. Confirmation sent. Contact removed from future campaigns.
Time-zone-aware windows held automatically. Nothing you have to remember.
SMS automation use cases
SMS automation FAQ
Scheduled campaigns and quiet-hours enforcement are included on every plan, including pay-as-you-go. Keyword auto-response is a $20/mo add-on. Opt-out handling is always on — it's not configurable.
The affected recipients are held until their local window opens, then delivered. The rest of the list goes on schedule. Nothing lands at 3 a.m.
Yes — up until the moment it fires. Edit the message, change the recipients, change the time, or cancel entirely.
Unlimited on the keyword add-on. Common ones: HOURS, INFO, VOTE, DONATE, RSVP, JOIN. Matching is case-insensitive.
Keyword auto-response handles fixed-trigger replies. For AI-assisted triage of open-ended replies, Alma — the AI-reply product in the CNX Suite — is a separate shipping product.
In practice, three things: (1) scheduled campaigns — queueing a message to send at a future time, optionally repeating, (2) keyword auto-responses — when someone texts a trigger word (HOURS, JOIN, INFO) the system replies automatically, and (3) quiet-hour enforcement — holding sends until each recipient's local 8 a.m.–9 p.m. window. CampaignCNX+ handles all three. It does not include flowchart-style "if-this-then-that" drip builders; in real operator use those are mostly abandoned.
Yes — through the keyword add-on. Set up triggers like HOURS, INFO, JOIN, DONATE, VOLUNTEER, and the platform sends the configured reply the moment a contact texts in the keyword. Matching is case-insensitive. For open-ended messages that don't match a keyword, the reply lands in the two-way inbox for a human to handle.
Not as a dedicated drip builder. What you can do: schedule a sequence of campaigns to a tagged audience at the dates you actually want them to land — a welcome message on day 0, a check-in on day 7, a re-engagement on day 30 — without drawing a flowchart. For most programs this is faster to set up and easier to audit than a flow-builder UI. For dynamic AI-assisted nurture, Alma in the CNX Suite is the right tool.
Automated: opt-outs, quiet hours, keyword replies, scheduled sends, recipient-time-zone resolution, send-time throttling for carrier compliance. Not automated (and shouldn't be): the actual message copy, the audience targeting, the send-time strategy, and the response to anything ambiguous in the two-way inbox. Operators stay in the driver's seat.
Start sending
Take the toll-free quick-start: purchase a verified phone number, schedule your first SMS batch, and set up a keyword auto-reply the same afternoon. For programs running automation at scale, 10DLC carrier registration is the recommended path for long-term deliverability and runs in parallel while you're already sending.
