Smstools review
A flexible SMS API platform with strong automation and two-way messaging tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Smstools is a cloud-based business messaging platform for sending and receiving SMS through web software or REST APIs. It is aimed at developers, businesses and IT teams that need transactional notifications, marketing campaigns, bulk messaging or two-way communication. Its feature set covers contact and group management, personalized campaigns, virtual SMS numbers, email-to-SMS and automated messaging, with infrastructure hosted in Europe and coverage across international mobile networks.
The published plans show a freemium structure. The Standard software and API plan includes software and API access, with SMS charges applied separately. U.S. SMS is listed at $0.025 per message, with pay-per-use and volume-based pricing. A U.S.A. virtual mobile number plan supports receiving SMS online and two-way SMS communication. Pricing varies by destination country and message volume, so organizations sending internationally should evaluate costs by market before selecting the service. Integrations with Zapier, Make, n8n, Slack, Microsoft Teams, HubSpot, Shopify, Salesforce, Mailchimp, ActiveCampaign, Klaviyo and Gmail broaden its fit across sales, commerce, support and marketing workflows.
For developers, the REST API supports sending and receiving SMS, while official SDKs are available for PHP, Node.js, Python, Ruby and PowerShell. Delivery reports, real-time message status, inbound SMS and reply webhooks provide the event handling needed for notification and response workflows. Contact management and campaigns add operational tools beyond a narrow messaging endpoint. Smstools suits teams seeking an API-first platform with a free entry point and optional business messaging features. It is less suitable for organizations that require open-source software or a single predictable price across international destinations.
