Execute a Flawless Ecommerce Product Release with SMS
A product launch is one of the few moments where a DTC brand has the whole audience's attention pointed in the same direction. Email gets you there slowly — opens trickle in over a day. SMS gets you there in the first ten minutes, with read rates that crush anything in the inbox. The problem is that most brands treat a launch text as a single "WE'RE LIVE" blast and call it a campaign.
That's leaving the best part on the table. A good launch is a multi-week arc — tease, build, drop, sustain — and SMS is the channel that controls timing better than any other. Below is the timeline I'd run, with real segment math so you know what the whole thing costs.
Full disclosure: I work for ReadySMS, so I'll use our pricing in the examples. The structure works on any platform; the numbers are just what I can verify.
Build the launch list before you have anything to launch
The single biggest mistake is waiting until launch week to think about who you're texting. Your SMS list compounds — every week you collect opt-ins is a week of subscribers who'll be there when the drop hits. Start months early if you can.
A few things that actually grow a launch-ready list:
- A dedicated "early access" keyword. "Text DROP to get first dibs + 15% off launch day." This self-selects your most motivated buyers and gives them a reason that isn't just "marketing."
- Checkout and post-purchase opt-in. Existing customers convert on new releases at a much higher rate than cold traffic. Capture consent at checkout and reinforce it in your post-purchase flow.
- A waitlist landing page for the specific product, with SMS as the notification method. People who waitlist a product are pre-sold.
Whatever you do, get the consent language right. A launch list assembled from sketchy opt-ins is a liability, not an asset. Our SMS consent strategy guide walks through the attestation and disclosure mechanics — and ReadySMS records opt-in attestation on bulk and API sends, so you have an audit trail if anyone questions it later.
Register your 10DLC campaign now, not on launch eve
If you're sending promotional blasts to thousands of contacts on an unregistered number, carriers will filter a chunk of your traffic — and you won't always know which messages got silently dropped. On launch day, that's catastrophic. You spent weeks building hype and a third of your "WE'RE LIVE" texts never landed.
A2P 10DLC registration runs roughly ~$10/mo per brand and ~$20/mo per campaign in carrier fees, with approval typically taking 1–3 days. ReadySMS handles the whole brand-and-campaign flow in-app. Do this well ahead of launch — if you cut it close and your campaign description gets rejected, you can lose the launch window entirely. The 10DLC compliance for ecommerce post covers what carriers want to see in the campaign use case so you get approved on the first pass.
Phase 1: Pre-launch (T-minus 2 weeks to T-minus 2 days)
This is where you manufacture anticipation. The goal isn't to sell — it's to make people feel like they already missed something if they don't pay attention.
A workable cadence for a two-week tease:
| When | Message type | Goal |
|---|---|---|
| T-14 days | Teaser ("something's coming") | Plant curiosity |
| T-7 days | Reveal date + sneak peek image | Lock the date in calendars |
| T-3 days | Early-access perk reminder | Reward the keyword crowd |
| T-1 day | "Drops tomorrow at 10am" | Final hype + time anchor |
Keep these short. A teaser like "Something new is landing next week. You're on the early list — watch this number 👀" with that emoji is unicode, which drops the per-segment limit to 70 characters. That message is one segment. Add a sentence and you're into multipart at 67 chars each. Worth knowing before you write, because the math compounds across a big list.
Say your launch list is 8,000 contacts and you send four pre-launch texts, each a single segment. On the Starter tier ($0.0084/segment + $0.0045 carrier pass-through):
- 8,000 × 4 segments × ($0.0084 + $0.0045) = 32,000 × $0.0129 = $412.80 for the entire pre-launch sequence.
That's the cost of two weeks of escalating hype to a high-intent audience. If your average order value is $60, you need to recover about seven orders to break even on the whole tease.
Phase 2: The drop (launch day)
Launch day is about precision, not volume. Two messages do most of the work.
The launch blast. Send it at a time your audience actually buys — for most consumer brands that's mid-morning or early evening, not 7am. Our best time to send SMS post gets into the windows. ReadySMS enforces quiet hours based on the recipient's local area, so a send scheduled for 10am won't accidentally fire at 7am for someone three time zones over.
The launch text should do three things: announce, link, and create urgency. "It's live. [Product] just dropped — your early-list 15% comes off automatically at checkout: [link]. Limited first run." No emoji here keeps it inside 160 GSM-7 characters if you're tight on length.
The "almost gone" follow-up. Six to eight hours later, hit the non-purchasers with scarcity if it's real: "Over half the first run is gone. Don't miss it: [link]." Real scarcity converts. Fake scarcity trains people to ignore you — don't claim sellout pressure that doesn't exist.
For the two launch-day sends to all 8,000 contacts, single segment each:
- 8,000 × 2 × $0.0129 = $206.40.
Add the pre-launch sequence and your full launch program lands around $620 in send cost for a six-message arc to 8,000 people. The carrier fees are itemized separately on the ReadySMS bill, so you can see exactly what went to us versus the carriers.
Phase 3: Post-launch (the part everyone skips)
The launch isn't over when the blast goes out. The post-launch phase is where you recover hesitant buyers and turn first purchasers into repeat customers.
Three flows matter here:
- Abandoned cart recovery. Launch traffic produces a spike in carts that don't convert — people who clicked, added, and got distracted. A timely recovery text reclaims a meaningful chunk of that. The abandoned cart SMS templates post has copy that actually performs, not the generic "you left something behind" line.
- Shipping and delivery updates. New-product buyers are anxious buyers. Proactive "your order shipped" and "out for delivery" texts cut support tickets and build trust for the next launch. There's a compliance angle to delivery updates worth reading — transactional messages have different rules than promotional ones.
- The restock waitlist. If the first run sells out, capture demand for round two with a "text RESTOCK to be notified" reply. You're building next launch's list off this one.
This is also where you measure. Track which phase drove revenue, what the cost-per-order was, and whether your early-access segment outperformed the general list (it should, by a lot). The ecommerce SMS conversion metrics post covers which numbers actually predict the next launch's performance.
A quick note on segmenting the launch
Not everyone should get the same six messages. Your early-access keyword crowd earned the perk and the extra teasers. Your broader list might only get the launch-day blast and the scarcity follow-up. Existing customers might get a "you've bought from us, here's first access" angle that cold subscribers don't.
Segmenting cuts cost and lifts relevance at the same time. If only 3,000 of your 8,000 contacts get the full pre-launch tease and the other 5,000 get just the two launch-day sends, your total send cost drops well below the $620 flat-blast number — and the messages land better because they're matched to intent.
If you're running on GoHighLevel, the native ReadySMS integration syncs inbound replies and outbound sends two ways, mapped per location, so your launch keyword replies and restock requests land in the same inbox your team already works.
The practical takeaway
A product launch over SMS isn't one big blast — it's a three-phase arc:
- Pre-launch: build a consented, registered list early and tease in escalating steps over ~2 weeks.
- Launch day: two precise sends — the announcement and a real-scarcity follow-up — timed to when people actually buy.
- Post-launch: recover carts, send delivery updates, and capture restock demand for the next one.
The whole six-message program to 8,000 contacts runs around $620 in send cost on the Starter tier — recoverable in roughly a dozen orders. Plug your own list size and order value into the cost calculator to see your numbers before you commit. And if you're starting fresh, the 2,500 free credits are enough to run a real pre-launch tease and see how your list responds before you spend a dollar.
