On two small islands where most people carry a phone everywhere, a text message is often the fastest way to reach someone. It is also the channel people forgive least when it is misused. This page covers how businesses in St Kitts and Nevis can use SMS well: who to text, what to send, how numbers work and which rules apply.
How numbers work in the Federation
St Kitts and Nevis is part of the North American Numbering Plan, so local mobiles use country code +1 and area code 869, followed by a seven-digit number: +1 869 XXX XXXX. Store every number in that full international format, even for local customers. It avoids failed sends when a contact writes down only the seven local digits, and it keeps local and overseas numbers in the same list. Mailpro’s phone country code list covers your overseas guests’ numbers too.
Mobile service on both islands is provided by Digicel and FLOW, and messages route through their networks. How a sender name appears can vary by destination and carrier; the sender name settings guide explains what you can configure.
What to text, and when
SMS works best for short, time-sensitive messages. Some uses that fit the Federation:
- Hurricane-season updates. From 1 June to 30 November, a quick text telling guests whether a tour is running or a hotel has reopened is worth more than any email.
- Arrival and excursion reminders. Pick-up times for cruise passengers, ferry-crossing reminders between Basseterre and Charlestown, or a note on where to meet the driver at the airport.
- Festival offers. A same-day message during the St Kitts Music Festival in June or on a Sugar Mas weekend, to people who asked for such alerts.
- Appointments and payments. Clinics, vets and service businesses can cut no-shows with a reminder the day before.
Mailpro lets you personalise each message with a first name or booking detail, and schedule SMS for a sensible hour in Atlantic Standard Time.
The rules on consent
We could not find a law in St Kitts and Nevis written specifically for SMS marketing. The Data Protection Act, 2018, which has been passed but was reported as not yet in force in February 2025, treats a phone number as personal data and makes consent the general basis for using it. Recipients abroad bring their own rules: in the United States, the TCPA restricts marketing texts sent without prior express consent, and in Canada, CASL covers text messages as well as email. The safe approach is the same everywhere: text only people who opted in to texts, identify your business, and include a way to stop messages. Mailpro’s pages on SMS laws and restrictions and collecting SMS opt-ins go further.
Measuring results
Every send produces a delivery report, so you can see which numbers failed and clean them out. SMS statistics show deliveries and clicks on tracked links, and you can compare them with your email results in the same account. In Mailpro’s own customer survey, users rated SMS deliverability 9.8 out of 10.
SMS or email?
Use SMS for what is urgent and short; use email for anything that needs pictures, detail or a long read. Many local businesses combine the two, a pattern described in combining SMS and email campaigns. If you are still deciding whether texting is worth it, read are SMS campaigns effective in St Kitts and Nevis. Credits and rates by destination are listed on the SMS pricing page.
