An SMS campaign is a short SMS to the right slice of your list - read within minutes, which makes it the channel for "this week" news: a cancellation opening, a flash promotion, a reminder that winter bookings are filling. Everything from Send a campaign applies - the honest audience count, the segments and groups, the report - this guide covers what's different about SMS.
What it costs
SMS come out of your monthly SMS credits, and the campaign tells you the cost before you send: "Uses about 86 of your 140 SMS credits" - measured on your real message, because a longer message can cost two credits per person. If you don't have enough, it won't start - and if credits somehow run dry mid-send, the campaign pauses and picks up where it left off when you top up.
- Every SMS starts with your business name and ends with "Reply STOP to opt out" - both counted in the length the cost shows.
- An SMS that fails to deliver hands its credit back. You pay for reached, not tried.
- Sends go out between 8am and 8pm in your timezone - a scheduled campaign that would land later waits for morning.
Writing an SMS
No headlines or photos - an SMS is its words. Fill-in fields work here too ({{first name}}, {{booking link}}), and the counter under the box shows the real length with your business name and the opt-out line included. The booking link in a campaign SMS is tracked, so the report can show bookings that came from it.
Who can receive SMS
The audience count is as honest as email's: it shows exactly who an SMS can reach and why each skipped person is skipped - no mobile number, an invalid number, not opted in, or replied STOP. STOP is platform-wide and instant; see SMS, STOP and staying welcome.
FAQs
Why did my campaign cost two credits per person?
An SMS up to 160 characters is one credit; a longer one uses more (and one with emoji or special symbols fits less per credit). The cost line always measures your actual message, business name and opt-out line included, so the number you see before sending is the number it costs.
Can I send the same campaign by email and SMS?
A campaign is one channel, chosen at the start. To say the same thing on both, duplicate the wording into a second campaign - each keeps its own honest audience and report.
