Messaging APIsready to ship

Pingram (formerly NotificationAPI) is a messaging API platform that gives developers and AI agents a single endpoint to send and receive email, SMS, automated voice calls, and WhatsApp messages. It replaces the need to stitch together SendGrid, Twilio, Resend, ElevenLabs, and other third-party services.

Twilio, Resend, and SendGrid each cover one or two channels and hand compliance work (like A2P 10DLC registration and email deliverability) back to the developer. Pingram provides email, SMS, voice, and push through one API, handles A2P 10DLC registration on your behalf, and exposes a single flat JSON shape that works well for AI agents and AI-generated apps.

Yes. Pingram is designed to be easy for AI agents and AI-assisted builders to use. The API exposes one flat endpoint with a predictable JSON payload, the SDKs are small and unambiguous, and Pingram publishes a machine-readable /llms.txt file plus LLM-optimized documentation so tools like ChatGPT, Claude, Cursor, Lovable, and Bolt can call the API correctly without trial and error.

Install the SDK (for example, npm install pingram), instantiate the client with your client ID and secret, and call pingram.send({ type: "welcome", to: { email: "user@example.com" }, email: { subject: "Welcome", body: "<p>Hello</p>" } }). The same call works for SMS, voice, and push — just include the relevant channel fields.

Call pingram.send({ type: "otp", to: { number: "+15005550000" }, sms: { message: "Your code is 123456" } }). You can start in Pingram's testing sandbox with real numbers and actual SMS delivery while production A2P 10DLC registration is in progress. Pingram handles carrier routing and inbound replies for production traffic once registration completes. You can use the same API for transactional SMS, OTPs, alerts, and two-way messaging from AI agents or bots.

Yes. Production US application-to-person (A2P) messaging on 10DLC is handled end-to-end by the Pingram team. You provide basic business and use-case information and Pingram submits, tracks, and iterates on the campaign and brand registration with the carriers — so you do not have to navigate the Twilio or carrier consoles yourself. Separately, Pingram offers a testing sandbox with real numbers and SMS delivery so you can integrate and validate before production registration finishes.

Yes. Pingram provides a testing sandbox that uses real phone numbers and delivers SMS through real carrier paths so you can validate templates, flows, and webhooks accurately. You can build and test there while Pingram manages production A2P 10DLC registration for live traffic.

Yes. Pingram supports inbound messaging via webhooks. When a user replies to an email or SMS, Pingram delivers a normalized JSON payload to your webhook URL with sender, subject, body, and attachments. This is useful for two-way support bots, scheduling agents, and AI assistants that need to read user replies.

Yes. Pingram has a free tier with 3,000 emails, plus 100 SMS and Calls per month, with no credit card required. Paid plans start at $20/month and and enterprise plans are available for high-volume customers.

Pingram provides official SDKs for Node.js, Python, PHP, Go, Ruby, Java, and C#/.NET, plus a React SDK for in-app notifications and a REST API that works from any language or runtime. It also integrates with Supabase, Auth0, and AI app builders such as Lovable, Bolt, and v0.
