SMS marketing and automation
Reach the inbox everyone actually opens.
We build SMS as a high-open, high-urgency channel — for time-sensitive offers, reminders, and transactional moments — used with the restraint the channel demands.
SMS is read almost immediately, which makes it valuable for messages that are urgent and harmful when overused. Booking reminders, delivery updates, payment nudges and genuinely time-limited offers belong on SMS; weekly newsletters do not.
We build SMS programmes with consent capture, sending rules and compliance for each market — TCPA and carrier registration in the US, DLT registration in India, PECR in the UK — and integrate them with your email and WhatsApp journeys so customers are not contacted on every channel at once.
The problem
SMS has near-universal open rates, but it's intrusive and easy to abuse. Overuse burns the list and the brand; underuse wastes the one channel almost everyone reads within minutes.

Building the SMS programme
We start with the messages SMS is best suited for: order and delivery updates, appointment and payment reminders, abandoned-cart recovery for high-intent shoppers, and a small number of genuinely time-limited offers. Each message type gets a clear trigger, timing and opt-out path. Transactional and marketing messages are kept separate, because consent rules and customer tolerance differ.
Sender setup comes before sending: carrier registration for business messaging in the US, DLT registration of the sender and templates in India, and the relevant consent records elsewhere. We then integrate SMS with email and WhatsApp so a customer does not receive the same message on three channels within an hour. Performance is measured on conversions and revenue per message, with opt-out and complaint rates monitored closely, because a channel this direct is quick to lose customer goodwill.
Frequently asked questions
Is SMS marketing legal?
Yes, with consent and compliance with local rules — for example the TCPA in the US, PECR in the UK and TRAI's DLT framework in India. Requirements differ, so we set up consent and registration for each market.
SMS or WhatsApp — which should we use?
In markets where WhatsApp is dominant, it often gets more engagement for marketing messages. SMS remains useful for reminders and for customers who do not use WhatsApp.
How often should we send marketing SMS?
Rarely, and only for messages that are genuinely timely. Over-sending drives opt-outs and complaints.
What is a reasonable SMS opt-out rate?
It depends on the audience and message type. Rising opt-outs or complaints are a signal to reduce frequency or improve relevance, and we monitor them for every campaign.
