What PureSMS is

PureSMS provides business-to-person SMS through a web portal and API. The portal handles individual, bulk, mail-merged, and scheduled messages, along with contact lists, Excel or CSV imports, and campaign analytics and reports. Messages can be sent as a concatenated message up to 900 characters or automatically split for unlimited length. Virtual mobile numbers enable incoming replies, and automated responses are available. A REST API supports integration into other systems, and the maker lists no-code integration through Zapier. SMS is billed per segment: messages longer than 160 GSM characters or 70 Unicode characters are split into segments. Pay-as-you-go SMS is $2.80, paid once, ex VAT, with international rates varying by destination; validated charities can use the Charity rate of $2.35, paid once. A Virtual Mobile Number is listed at £10/mo. The maker says its systems are certified to ISO 27001, ISO 9001, and ISO 22301, and that it complies with UK and EU GDPR and checks customers' PECR compliance during sender checks. It also describes sender verification and traffic monitoring among its fraud controls.
