SMS marketing basics: consent, registration and messages people welcome

0:00 SMS marketing basics

Think about the last text message you got from a business. Was it useful, like your parcel is out for delivery? Or was it one of those texts you delete before finishing the first line? SMS is powerful because it reaches almost any phone and gets read quickly. That's exactly why it's so easy to abuse, and why regulators and mobile carriers treat it strictly. In this lecture you'll learn when SMS earns its place, the consent and registration rules in the US, UK, UAE, Saudi Arabia and Pakistan, how to write texts people welcome, why message length affects cost, and how to keep one suppression list across every channel.

0:48 When SMS works

So when does SMS earn its place? For time-sensitive, high-value messages people asked for. Delivery and appointment updates. One-time passcodes. Back-in-stock alerts for people who requested them. And occasional flash sales or early access for VIPs who opted in. Here's the key idea: SMS is the most intimate marketing channel after a phone call. It sits between messages from family and friends. So keep it short, rare and wanted. If a text wouldn't feel welcome coming from a friend who works at your company, don't send it.

1:26 US rules

Now the rules, starting with the US. The Telephone Consumer Protection Act generally requires prior express written consent for marketing texts sent with automated systems. You must honour opt-outs like STOP promptly, follow calling-hour limits, and check stricter state laws. There's also registration. Business texting from standard ten-digit numbers requires what's called A2P ten D L C registration of your brand and campaign. Toll-free numbers need verification, and short codes have their own approval. And industry guidelines expect clear opt-in, a frequency disclosure, and HELP and STOP keywords. Your SMS provider walks you through it, but you're responsible for the consent.

2:10 UK/EU, UAE, KSA, Pakistan

In the UK and EU, the PECR and ePrivacy rules generally require consent for marketing texts to individuals, with the UK soft opt-in for existing customers about your own similar products, and an opt-out in every message. Always identify the sender and offer a free, simple opt-out. In the UAE, the telecoms regulator, the TDRA, requires registered promotional sender IDs with an AD dash prefix, restricts promotional texts to daytime hours, commonly cited as seven a.m. to nine p.m., and requires opt-out instructions. In Saudi Arabia, sender names are registered through licensed providers, and the data protection law requires consent and an opt-out. And in Pakistan, the PTA regulates bulk SMS, so use licensed, registered providers.

3:00 Welcome texts

Now, writing texts people welcome. Identify yourself first, like Leaf and Loom colon, at the start. One message, one action, one link, ideally a short link on your own domain, because generic link shorteners can look like scams. Always include the opt-out: reply STOP to opt out. And respect time: local time zones, quiet hours, Friday prayers and Ramadan evenings. Here's a simple example from the lesson text. Leaf and Loom: VIP early access, new linen kurtas live now, twenty-four hours before everyone else, then a short link, then reply STOP to opt out. About a hundred and forty characters. Clear, useful and easy to leave.

3:46 Length and cost

Let's talk about length, because it affects cost. Standard SMS uses an alphabet called GSM seven, which allows a hundred and sixty characters per segment. But if your message includes characters outside it, including many emojis, and Arabic or Urdu script, it switches to Unicode, called UCS two, and each segment holds only seventy characters. So a hundred-and-fifty-character Arabic message might be billed as three segments instead of one. The lesson text has a quick Google Sheets formula to count characters and flag Unicode, though your provider's preview is the final word. Short messages aren't just better manners. They're cheaper.

4:29 Example 1: Texas apparel (illustrative)

Let's do a simple worked example, with illustrative results. A Texas apparel brand launches SMS. It registers its brand and campaign for A2P ten D L C through its provider. It adds an SMS opt-in step right after email sign-up, with the required disclosures: message frequency varies, message and data rates may apply, reply HELP for help and STOP to cancel. And it caps marketing texts at four a month. VIP launches by text sell out faster than email launches, and opt-out rates stay low. The discipline is the product: registered, consented, disclosed, and capped.

5:10 Example 2: Dubai restaurants (illustrative)

Now a realistic Gulf scenario. A Dubai restaurant group uses SMS for reservation confirmations, which are transactional, and a monthly offer to diners who opted in, sent from an AD dash sender ID, before the evening cut-off, with opt-out instructions. WhatsApp handles conversational bookings, like changing a table for four to six. And email carries the monthly newsletter with the menu and events. Each channel does the job it's best at. That's the real lesson of this module: SMS, WhatsApp and email aren't competitors. They're a team, as long as consent and suppression connect them.

5:51 Suppression + mistakes

Which brings us to suppression. Opt-outs must be honoured where they apply. Connect SMS, email and WhatsApp tools to a single consent and suppression record, like the one in the compliance lesson. A STOP by text stops SMS marketing. Decide, and document, whether it also affects other channels. And never re-add someone without new consent. Common mistakes: texting numbers collected for delivery as if they were marketing opt-ins, long emoji-heavy messages that split into costly segments, missing sender identification or opt-out, and sending at night or across time zones without checking.

6:31 Measure success

How do you measure success? Track your opt-in rate, your opt-out rate per send, which should stay low, and your delivery rate. Compare click-through and revenue per message sent with email and WhatsApp. And calculate cost per conversion including segment costs, because a channel that looks efficient per message can be expensive per sale if messages split into several segments. If SMS opt-outs start climbing, cut frequency before anything else. With SMS, fewer and better messages almost always win.

7:05 Recap and try this now

Let's recap. Use SMS for short, time-sensitive, high-value messages people asked for, and keep frequency low. Consent rules differ: written consent and ten D L C registration in the US, consent or the soft opt-in in the UK and EU, AD dash sender IDs and daytime windows in the UAE, and registered senders in Saudi Arabia and Pakistan. Identify yourself, use one link and always include STOP. Watch segment length, especially with Arabic or Urdu. And keep one suppression record across every channel. Here's your try this now. Write three texts from the lesson text's templates for a business you know, check their length, and list the consent and registration steps for your market.
