Whispir review

Whispir is a Melbourne-headquartered enterprise messaging and workflow platform, presented on its current pages as a solution by Soprano. The platform sends and receives SMS in Australia, including two-way messaging, and runs campaigns, templates and triggered workflows from a browser. Whispir publishes platform plan prices but no verified comparable Australian per-message rate, so you will need a quote to compare message costs with other providers.

One of 45 brands reviewed. Not in the priced comparison: publishes no Australian rate.

Right for you if
  • API, email-to-SMS and two-way messaging are offered, with dedicated numbers and alphanumeric sender IDs
  • Support is offered by phone within Australia on 1300 WHISPIR (1300 944 774) and by email
  • The platform is certified under ISO/IEC 27001 and ISO/IEC 27018, with a SOC 2 Type II report
Look elsewhere if
  • Published plans leave comparable Australian SMS pricing unresolved, so a quote is required before comparison.
  • Feature access varies by plan and should be checked against your requirements before purchase.
  • Administrators are the primary support contact unless otherwise agreed, and your SLA determines turnaround.

Where Whispir stands

Whispir is an enterprise cloud messaging and workflow platform, Melbourne headquartered and now presented as a solution by Soprano. It offers Australian two-way messaging, REST API access and configurable workflows that respond to inbound SMS. Support runs primarily through client administrators, who are trained to manage implementation and assist users. Published platform plans do not establish a comparable Australian SMS rate, so a quote is required before comparison.

How Whispir prices

Whispir publishes monthly platform plans, but those amounts do not give a comparable Australian SMS rate. Currency, GST treatment, the Australian SMS allowance and per-message or overage costs are all unresolved. Request a quote covering these points, required features and reply-number charges.

Whispir pricing

The plan cards on the Australian marketing page describe bundled monthly platform features rather than a standalone Australian message rate. They do not state currency, GST treatment, whether the bundled messages apply to Australian SMS, or an overage rate. Treat them as a platform subscription and ask the sales team for a quote covering currency, GST, the Australian message allowance, overages, reply numbers and required features.

Whispir workflows

Whispir is cloud based, accessed through a browser with your account credentials. Workflows respond to inbound messages and trigger outbound ones across channels, so an event signup SMS can generate a confirmation email, and third-party integrations can start sends. Templates, lists, reporting, roles and permissions are configurable, so identify the internal owner of that setup before you buy. Our SMS automation guide explains the campaign tasks any automation platform should handle.

Whispir API integrations

The developer reference describes a REST API for creating, sending and retrieving multichannel messages, invoking scenarios, building rich cross-channel templates and managing distribution lists. Message responses arrive asynchronously. Authentication and testing guides exist in the documentation, but throughput and rate limits were not verified for this review, so confirm them against your expected send volumes. Our SMS API guide covers the integration questions worth asking before you choose a gateway.

Whispir sender IDs

Whispir's own article on the ACMA register describes branded sender names as sender IDs and offers registration assistance for organisations with and without an ABN. The practical setup task is to identify the brand names you intend to send from, confirm with Whispir that each is registered before you use it, and avoid any name you have not cleared. Our SMS Sender ID Register guide explains what the register covers and what it does not.

Whispir security evidence

Soprano reports SOC 2 Type II coverage and ISO 27001:2022 certification for the Whispir platform in its security release. The same release covers other credentials scoped to Singapore and UK entities, which do not automatically extend to your Australian account. A report and a certification describe an audited control environment, not a guarantee of delivery or uninterrupted service, and no independently measured delivery rate or uptime figure was verified for this review. Ask for the current scope documents as part of your quote.

Whispir support arrangements

Whispir directs urgent issues to phone support and other requests to an email address that raises a ticket, with a customer SLA that sets severity levels and turnaround times. Service Management primarily serves client administrators unless agreed otherwise, and administrators are trained and supported to run the implementation and teach internal users. If your users would need a direct path to Whispir, raise that exception during the quote. Confirm support hours, escalation paths and SLA terms in writing before signing.

Who Whispir suits

Whispir suits Australian organisations that need a workflow platform with two-way SMS, triggered multichannel messaging and API integration into existing systems, and that have someone to administer it. It is a weaker fit if you want a published per-message rate, simple bulk sending without workflow setup, or support that reaches every end user by default. Weigh price transparency and administrative capacity in your quote.
