Mass texting service

Mass texting and bulk SMS broadcast software — personalized per contact at any scale.

Import a CSV, write one text message with merge fields, and send it to everyone on the list who should get it. Opt-outs are filtered automatically, the total cost is visible before send, and delivery status updates in real time. It's the same mass-texting workflow whether your list has 200 contacts or 40,000.

01 — Compose

Mass texting with merge fields — one message, personalized per recipient.

Drop a merge field where the first name goes and write the rest of the message the way you'd write it for a single contact. The bulk-SMS composer shows live segment count and total cost as you type, so nothing ships by surprise.

  • Merge fields for first_name, last_name, and any custom column
  • Live character and segment count
  • MMS attachments for flyers, polling cards, and product images
  • STOP opt-out language validated before the campaign can go out
  • Single-contact preview to check the merge output

02 — Review and send

Bulk SMS review screen: recipient count, total cost, and preview before send.

The review screen is a single panel that shows your final recipient count, the total cost in dollars, and what the personalized message will actually look like to one real contact. Send immediately or schedule for a future date — nothing leaves the platform until you confirm.

  • Final recipient count after opt-outs and DNC flags drop out
  • Total cost shown in dollars — not in credits
  • Overage surfaced on monthly plans ("this campaign uses X overage messages at $Y")
  • Immediate or scheduled delivery with time-zone-aware windows

How mass texting works

How to send a mass text in four steps: type, recipients, compose, send.

There's no separate bulk-texting flow or hidden enterprise pricing page — the broadcast you build for a 200-contact list is the same one you'd build for a 40,000-contact list.

01

Pick the type

SMS or MMS. Cost per segment surfaces immediately so you know what the campaign will cost.

02

Select recipients

A group, a tag, or a filter. Opt-outs filter automatically; DNC-flagged contacts drop out.

03

Compose

Merge fields, live segment count, MMS attachments, STOP language validated before send.

04

Review & send

Final recipient count, total cost, one-contact preview. Immediate or scheduled.

TCPA compliance on the send path

TCPA-compliant mass texting: opt-outs, DNC, quiet hours, and 10DLC built into every send.

/01

Opt-outs filtered at send

Anyone who texted STOP, HELP, or UNSUBSCRIBE is already out of the recipient count before you review.

/02

DNC registry (add-on)

Run a list against the federal DNC registry via DataZapp. Pay only for what you verify.

/03

Quiet hours

Time-zone-aware windows enforced automatically. Nothing lands at 3 a.m. because someone scheduled wrong.

/04

10DLC registered

Toll-free quick-start sends same day. 10DLC runs in parallel for programs where long-term deliverability matters.

Who uses mass texting

Mass texting FAQ

Mass texting FAQ — questions to answer before a big bulk SMS broadcast.

Is there a recipient cap per campaign?

No hard cap on how many contacts you can include in a single campaign. Your plan's bundled SMS count determines what's included vs. what shows as overage — but the send itself isn't throttled at the platform level.

What does a campaign cost?

Pay-as-you-go is $0.06 per SMS and $0.15 per MMS. Monthly plans bundle SMS at lower effective rates: Basic $55/mo (1,000 SMS, ~$0.055), Pro $225/mo (5,000 SMS, ~$0.045), Enterprise $695/mo (20,000 SMS, ~$0.035). Overage bills at the plan's own rate, not PAYG.

Can I schedule campaigns in advance?

Yes. Schedule days or weeks ahead. Scheduled campaigns respect recipient time zones — a message scheduled for 10 a.m. doesn't land at 7 a.m. for someone in a different zone.

What happens to opt-outs?

Anyone who replied STOP, HELP, or UNSUBSCRIBE is filtered out before the recipient count is locked in. Handled platform-wide — works whether two-way messaging is enabled or not.

How fast can I start?

Toll-free quick-start sends the same day you open an account. 10DLC registration is the recommended path for high-volume or long-term programs and runs in parallel — you send on toll-free while 10DLC processes.

Is mass texting legal?

Yes — when it's done with documented consent, honors opt-outs, and respects quiet hours. The TCPA doesn't ban mass texting; it requires that recipients have given express written consent and that you give them a way to stop. CampaignCNX+ enforces opt-outs, quiet hours, and STOP language at the send path; getting consent at opt-in is your responsibility.

What's the difference between mass texting and group texting?

Group texting (the iMessage / "everyone replies to everyone" experience) is for small social groups — typically capped at a few dozen recipients, with everyone seeing each other's replies and phone numbers. Mass texting is one-to-many at scale: each recipient gets a private one-on-one thread with the sender. Replies route back only to your inbox, never to other recipients. Mass texting is the right tool for any list above ~20 people and for anything customer-facing.

Can I send a mass text from my iPhone?

iMessage and the Messages app can broadcast to maybe 30 recipients before carriers start throttling, and they don't carry consent records, opt-out handling, or audit trails. They're not built for compliant marketing. A platform like CampaignCNX+ is what you use when "broadcast a text to my list" needs to be repeatable, compliant, and trackable.

How big a list can I send to in one go?

No platform-imposed cap. Real-world send rates are gated by carrier throughput — a registered 10DLC number can typically push tens of thousands of segments per hour. Larger sends spread across the throughput window automatically; the dashboard shows progress in real time. If you're sending to a list above 50,000 recipients, talk to onboarding so we can stage carrier throughput appropriately.
