This ClickSend review covers pricing, deliverability, the API, and how it compares to Twilio and Plivo.
Send SMS and MMS to 220+ countries with direct carrier connections — competitive per-message pricing, no markup on international routes, and real-time delivery reports.
Production-grade REST API with official SDKs for Node, PHP, Python, Ruby, Java, .NET and Go — most dev teams ship a first send inside an hour.
Send transactional and marketing email alongside SMS through the same platform with tracking, bounce handling, DKIM/SPF and dedicated IP options.
Voice API delivers text-to-speech messages, OTP calls, announcements and IVR menus — same auth and billing as SMS, useful for OTP fallback.
Upload a CSV or call the API and ClickSend mails real postcards, letters and brochures anywhere worldwide via a global print network — no envelopes to lick.
Rent dedicated local and toll-free virtual numbers to receive SMS replies, route them to email, Slack or a webhook and run inbound keyword campaigns.
Drag-and-drop campaign builder with contact lists, merge fields, link shortening, scheduling and A/B tests — no developers needed for marketing sends.
Pre-built integrations with HubSpot, Salesforce, Zapier, Zoho, Mailchimp, WooCommerce, Shopify and a Microsoft 365 add-in connect ClickSend to existing workflows.
ClickSend uses a pay-as-you-go model with no monthly fees or contracts. Pricing scales with message volume, and you only pay for what you send. Account top-ups start at just $20 USD. Carrier fees are passed through at cost.
Volume discounts apply automatically. Enterprise customers sending 100,000+ messages/month can negotiate custom rates. A free trial credit is available for new accounts.
Verified G2 and Capterra reviews from ClickSend developer and operations teams.
We use ClickSend for SMS appointment reminders, transactional email, and online fax for HIPAA workflows. The API was up and running in our backend in under an hour. SMS deliverability has been rock solid across the US and UK. Pricing is much cheaper than Twilio at our volumes.
If ClickSend does not match your needs, top alternatives include Twilio (industry-standard developer-first communications), MessageBird (omnichannel with strong WhatsApp), Plivo (developer-friendly with low-cost SMS/voice), Vonage (enterprise communications APIs), and SimpleTexting (US-focused SMS marketing).
