SMS Programme Setup on Attentive or Postscript

Consent decides the programme: In the Netherlands and across the EU, SMS marketing needs prior opt-in under article 11.7 of the Telecommunicatiewet, or an existing customer relationship for similar products. That is why a Dutch programme is built around post-purchase and appointment moments rather than a broadcast calendar. In the US the same programme needs express written consent, quiet hours, and 10DLC brand and campaign registration through The Campaign Registry before a single message routes. Built this way, four thousand opted-in numbers at five sends a month earn more than forty thousand collected through a checkout box nobody read. Choosing the platform, out loud: Postscript when you are on Shopify and want the cheapest correct answer. Attentive when there is more than one storefront, a service desk that has to see the thread, or a US number pool that needs managed carrier relationships. Klaviyo SMS when your flows and profiles already live there and a second identity store would create two versions of the same customer. Sometimes the answer is none of the three: a clinic or an estate agency usually needs appointment messaging attached to the booking system, and I will say that rather than set up a marketing platform you will open four times. Collection, and where the number is asked for: Two-tap opt-in, no pre-ticked boxes, and the ask placed where value has just been delivered: after a viewing is booked, after a second order, at the moment a delivery date is confirmed. Mobile and desktop get different mechanics, because typing a number on a laptop is the reason your desktop opt-in rate is a third of mobile. Consent text, timestamp and source stored against the profile, since in two years the only question that matters is which of these people said yes and when. The flows: Six, written and built. Welcome, with the offer stated in the first message rather than teased. Browse abandon at four hours, not twenty minutes, because twenty minutes reads as surveillance. Back in stock. Replenishment timed from your own reorder intervals rather than a thirty-day default. A post-delivery check-in that asks something answerable. And a winback that says it is the last message and then is. Every flow exits anyone with an open support ticket. How it is measured: A permanent ten percent holdout. Attentive and Postscript both report attributed revenue on click and view windows that credit themselves for purchases that were happening anyway. The number I report monthly is incremental revenue against holdout. It is smaller and it is true, and the first month usually involves an uncomfortable conversation about the difference between the two figures. Frequency, against the email calendar: One rule overrides everything else: nobody receives a marketing SMS and a campaign email inside twelve hours. SMS interrupts, email waits, and a brand running both without a shared calendar teaches its list to mute one of them. The send calendar is set at four to six a month, and I will argue about the seventh. Not included: Carrier registration fees, short-code lease and message throughput charges, which are yours and which I will estimate before you sign. Ongoing campaign copy once the flows are live. List purchase or number append: an appended number has no consent record, and the record is the asset. No consumer programme promoting a prescription-only medicine, which the Geneesmiddelenwet forbids and no brief changes. Who this is not for: Brands with an average order value under twenty-five euros and no repeat purchase, where message cost eats the margin before the second send. And anyone who wants SMS as a discount tap: a list trained on twenty percent off will not open anything that is not, and undoing that takes about a year.
