Global Business Communications | SMS, APIs, SMPP, WhatsApp, Email & Voice

Connect transactional messaging, customer engagement, authentication and service conversations through a consistent communications layer designed for mission-critical operations, developer integration and responsible use.

Channel and destination availability can vary by country, sender type, business verification, provider connectivity, account configuration and applicable requirements.

One communications layer across multiple channels.

Zayloft organizes business communication around channels, senders, recipients, templates, consent state, delivery events and account-level controls. This gives product teams and operations teams a consistent way to manage communication while respecting differences between markets and channels.

Channels for customer communication

SMS

Send transactional alerts, verification messages, service notifications and consent-based customer communication using account-enabled sender routes and destination-aware controls.

WhatsApp Business

Connect customer-owned WhatsApp Business accounts for approved business messaging, templates, customer conversations and webhook-driven events where the channel is enabled.

RCS

Support rich branded messaging experiences with interactive content where RCS business messaging is available for the destination, sender and account.

Email

Deliver transactional and customer-engagement email through authenticated domains, templates, event feedback and suppression-aware sending workflows.

Voice

Use programmable calling patterns for alerts, routing, IVR, verification and service workflows, subject to account configuration and jurisdiction-specific requirements.

Video

Enable real-time video experiences for support, appointments and embedded customer interactions through approved communications workflows.

Push & in-app

Coordinate mobile push and in-app notifications with customer profiles, events, preferences and other communication channels.

Web & live chat

Bring website and in-product conversations into customer-support and engagement workflows with routing, automation and human handoff.

SMS for applications and high-volume operations.

Zayloft supports application integration through RESTful messaging APIs and account-scoped SMPP connectivity for organizations with approved high-volume requirements. Delivery reporting, idempotency, message status and sender configuration are treated as operational primitives rather than afterthoughts.

RESTful messaging API

Use HTTPS and JSON to submit messages, retrieve status, connect delivery events and integrate messaging into web, mobile and backend applications.

SMPP 3.4 connectivity

For accounts configured for telecom-style integration, SMPP supports persistent sessions, message submission, delivery receipts and sustained messaging workflows.

Delivery events & webhooks

Receive lifecycle and delivery events through signed callbacks so applications can reconcile message state without exposing upstream provider details.

Senders & routing

Manage sender identities, numbers and routes according to the destination, account configuration and requirements that apply to the message purpose and market.

Standards familiar to serious engineering teams.

Different channels require different protocols. Zayloft keeps those details behind a coherent product layer while supporting the interfaces that enterprise and telecom teams expect.

Global communications require local awareness.

A message that is acceptable in one country, on one channel or for one purpose may require different consent, sender registration, templates, disclosures, timing or routing elsewhere. Zayloft is structured to represent those differences instead of applying one regional rule everywhere.

Country-aware sender requirements

Sender IDs, numbers, registrations and approval processes can differ by destination and message category.

Consent and preference state

Maintain opt-in evidence, communication preferences, opt-out state and suppression controls that can be applied at the appropriate channel and recipient level.

Purpose-aware messaging

Separate transactional, authentication, service and marketing workflows so the correct policies and content controls can be applied.

Market-aware routing

Evaluate destination, sender type, account eligibility and available routing without exposing internal provider credentials or privileged infrastructure data.

Responsible communications are part of the operating model.

Zayloft provides technical controls that help organizations manage consent, opt-outs, suppression, sender requirements, templates, routing and auditability. Requirements differ by destination, channel, audience and use case, and customers remain responsible for ensuring their communications are authorized and appropriate for the markets and audiences they address.

Common communication workflows

Authentication & account security

One-time passcodes, login verification, account alerts and risk-aware authentication communication.

Transactional notifications

Order confirmations, payment updates, delivery events, appointment reminders and operational alerts.

Customer service

Support conversations, case updates, service notices and human-agent communication across enabled channels.

Lifecycle engagement

Consent-based onboarding, reminders, product education and customer-retention communication.

Campaign communication

Audience-based promotional communication where the organization has the permissions and channel eligibility required for the destination and use case.

Operational communication

Logistics, field-service, education, marketplace and workforce messages that keep people informed about legitimate business activity.

Communication infrastructure with controlled access.

The platform is structured around account isolation, scoped credentials, secure transport, signed callbacks, auditable configuration changes and restricted exposure of internal routing or provider information.

Scoped API and project credentials

Signed webhook verification

Test and live environment separation

Role-based access and auditability

Rate and abuse controls

Tenant-aware data boundaries

Availability and pricing follow the actual route and service.

Communication pricing and availability can vary by destination, channel, sender type, route, message category, volume, account agreement and taxes or fees that apply. Account-level pricing should be treated as the authoritative commercial source for enabled services.

Connect customer communication to the systems your business already uses.

Use Zayloft to bring messaging, delivery events, customer conversations and channel-specific communication into one integration model while retaining the controls needed for mission-critical operations.
