Compliance first, always
A2P 10DLC registration, toll-free verification, TCPA consent records, and quiet-hours QA before a single campaign goes out. Statutory damages run $500 to $1,500 per text; we treat that as a design constraint.
Flows carry the money
Klaviyo's 2026 benchmark data puts automated flows at 7.6% of sends but 45.2% of SMS revenue. We build welcome, cart, browse, and win-back flows before we ever talk about blast calendars.
Lists that stay opted in
89% of US consumers now take texts from businesses, and frequency is the top reason they leave. We grow through checkout opt-ins and exclusive offers, then guard opt-out rates every send.
Why we exist
SMS died a little every time someone blasted a full list at 9pm
We started Coolnetworky in Austin after watching the same story repeat: a brand buys a platform, imports every phone number it can find, sends identical blasts, and burns its list inside a quarter. The channel works. Texts pull a 12.39% campaign click-through against email's 0.74% on the same Omnisend dataset. Careless senders squander it.
So we run SMS the way it holds up: consent you can produce in a dispute, flows tuned to Postscript's published benchmark bands, copy tested under the 240-character ceiling where conversion drops 8.5%, and send caps that respect the person on the other end. Read how that plays out in our Write-ups or see the method on our Process page.

Quick answers
SMS marketing questions we hear every week
Yes, with documented consent. The TCPA requires prior express written consent before marketing texts: a signed opt-in that names your brand and states that consent is not a condition of purchase. Since April 2025, opt-outs made by any reasonable method must be honored within 10 business days. Quiet hours also apply: no marketing texts before 8am or after 9pm in the recipient's local time zone.
Platform costs run from $25 to $39 per month at entry (EZ Texting, SimpleTexting) up to roughly $0.007 to $0.009 per message plus fees on Shopify platforms like Postscript. Carrier surcharges add about $0.0035 to $0.0045 per text. Our management pricing is published: a $1,500 audit, a $4,200 launch package, or a $2,900 monthly retainer.
A2P 10DLC brand and campaign registration usually clears within days, though carrier vetting can stretch longer, and toll-free verification takes about 3 to 5 business days. Our fastest launch went from zero to a first revenue campaign in 18 days, including registration, welcome flow, and checkout opt-in setup. Plan on two to four weeks for a clean start.
Some churn is normal: per-campaign opt-out rates between 0.33% and 0.88% sit inside Postscript's published benchmark band. Frequency is the top trigger, named by 40% of consumers in EZ Texting's 2026 survey. We cap sends per subscriber, segment by engagement, and watch opt-outs on every campaign; our median program holds at 0.38%.
