[H2] Top-performing SMS programs don’t happen by accident
SMS has become a core revenue channel for e-commerce brands, but most SMS programs are under-managed. The reality is:Most teams don’t have the time or expertise to keep SMS running at a high level.Automations get set up once and are rarely optimized, leaving revenue on the table.Too many SMS decisions are made without clear proof of what’s actually working.

[H1] Stay compliant and scale confidently
Compliance shouldn’t be scary—or slow you down. Postscript helps brands reduce legal risk, respond faster, and grow with confidence.Book a Demo
[H3] Staying compliant with SMS laws is harder than it should be.
One wrong message — even with good intent - could cost you $500 to $2,000 per send. We'll help you stay protected with built-in playbooks, audit-ready records, and a real support system when things go sideways.
[H2] How we protect merchants
[H4] Guardrails included
Playbooks built into our product to mitigate risks from shakedown lawsuits like Quiet Hours and opt-out traps.
[H4] Trusted defense on deck
A trusted network of highly-skilled TCPA litigators with pre-negotiated discounted rates and already ramped on SMS law and Postscript tools.
[H4] We have the receipts
Message and consent records for subscribers collected using Postscript-powered popups — no extra setup, ready if you need them.
[H4] Regulations evolve—and so do we
All Postscript customers get a free EIA membership — with expert guidance and alerts to keep up as laws change.
[IMG: quiet-hours-ecomm-alliance]
[H3] Scale SMS safely and compliantly
Over 90% of merchants who used our Quiet Hours strategy paid $0 in settlements and spent less than $5K on legal fees, compared to the $50K industry average.Postscript co-founded the Ecommerce Innovation Alliance (EIA), which filed a petition with the FCC to stop frivolous Quiet Hours lawsuits—accepted for public comment in 2025.
[H3] With Ridge, we made history
Ridge got hit by a lawsuit that exposed how broken the rules really were. We stepped in—not just with legal support, but with real action. Together, we helped overturn the law and protect other brands from the same trap.
[IMG: Ridge]
"Postscript didn’t tell us to settle. They said, ‘this is unfair—we should change it.’ Then they backed it up with their own legal team, their own money, and actually changed the law."
