Turn SMS into email. Turn email into SMS.

smsemailsms.com bridges email systems and mobile SMS. Deliver alerts instantly by text message, route inbound SMS into shared inboxes, and integrate with inbound webhooks and outbound APIs for automation and two-way messaging.

Two-way routing Inbound webhooks Outbound API Audit & controls

How it works

Configure routing once, then plug your tools into the gateway. Typical setups forward inbound SMS into a shared mailbox, convert operational emails into outbound SMS for on-call escalation, and deliver inbound messages to your app via webhooks.

SMS → Email: inbound SMS is received and forwarded to one or more email addresses (shared inboxes, ticketing, audit trails).
Email → SMS: emails from monitoring, CRMs, and internal apps are transformed into outbound SMS alerts.
Inbound SMS webhooks: deliver inbound SMS to your application as structured HTTP POST payloads for automation and routing.
Outbound SMS API: send SMS programmatically via a simple HTTPS API (notifications, OTP, on-call routing).
Two-way flows: replies can be routed back into email threads or to a webhook endpoint depending on your integration.

SMS delivery can be affected by carrier policies, regional regulations, sender-ID rules, and network delays. For critical workflows, use retries, fallbacks, and escalation policies.

Who it’s for

A simple bridge for teams and systems that need messages to move reliably between channels.

Monitoring & on-call

Send critical alerts as SMS, route acknowledgements back to email or a webhook workflow.

Support & ticketing

Capture inbound SMS into a shared inbox or ticket system with audit trails and routing rules.

SaaS & automation

Trigger SMS from email-only systems, and ingest inbound messages as structured events.

API shape

Integrations are lightweight HTTPS requests. Use outbound APIs to send SMS, inbound webhooks to receive SMS, and routing rules to transform messages between channels (email triggers → SMS, SMS replies → email/webhook).

Example routes (illustrative only — not live on this website):

Outbound SMS

POST /api/send-sms

Fields: to, message, optional metadata

Inbound SMS webhook

POST /api/inbound-sms

Fields: from, to, message, timestamp

// Outbound SMS request (example)
{
  "to": "+447700900123",
  "message": "Alert: service latency is high",
  "tags": { "system": "monitoring", "severity": "warning" }
}

// Inbound SMS webhook payload (example)
{
  "from": "+447700900123",
  "to": "+447700900999",
  "message": "ACK 12345 - investigating",
  "received_at": "2026-02-27T12:34:56Z"
}

Webhooks can be signed (e.g. HMAC signature + timestamp headers) so your app can verify authenticity and prevent replay attacks. Provider selection, throughput, and authentication depend on your deployment.
