Reliable transactional email, SMTP delivery and email verification for businesses that depend on email every day.
When email is part of your core product or business workflow, reliability, visibility and control matter.
Deliver the messages your customers and internal teams rely on, including account notifications, receipts, alerts and other transactional communication.
Build your email infrastructure around increasing application traffic and growing customer demand.
Connect websites, SaaS products, internal systems and customer-facing applications through a consistent email infrastructure.
Track delivery activity and integrate email events into your existing systems using webhooks and application workflows.
Enterprise email infrastructure needs more than a way to send messages. It needs authentication, visibility, failure handling and integration with existing systems.
Connect production applications through REST APIs or standard SMTP without replacing the systems your teams already use.
Organize sending domains, credentials and application workflows around the requirements of production email.
Connect email events to your applications and internal systems so teams can respond to delivery activity.
Handle bounces, complaints and suppressed recipients without repeatedly attempting delivery to addresses that should no longer receive email.
Sendzovo provides the core tools needed to build and operate reliable email workflows at scale.
Send application-generated emails through a developer- friendly REST API.
Connect existing applications and systems using standard SMTP without rebuilding your email stack.
Validate addresses before sending to reduce invalid addresses and unnecessary delivery attempts.
Connect email activity to your applications and operational systems through event-driven workflows.
Introduce Sendzovo without redesigning the applications and infrastructure your engineering teams already operate.
Applications can send transactional email directly through the Sendzovo REST API using authenticated requests.
Existing software that already supports SMTP can connect to Sendzovo without requiring a custom API integration.
Send email events back into your application or operational systems through webhooks.
Validate addresses before sending so applications can make informed decisions about recipient quality.
Build your sending infrastructure around predictable workflows and clear delivery signals.
Authenticate your sending domains with the DNS records required for modern email delivery.
Prevent repeated delivery attempts to addresses that should no longer receive messages.
Capture delivery failures and use those events to improve application and sending workflows.
Use email events and webhooks to keep your systems informed about what is happening with your messages.
Build email workflows around authenticated domains, controlled credentials and application-level integration.
Authenticate the domains used by your applications through the DNS records required for email delivery.
Authenticate API requests so applications can securely communicate with the Sendzovo email infrastructure.
Connect SMTP-compatible applications using encrypted transport for production email workflows.
Prevent messages from being repeatedly sent to recipients that should no longer receive email.
Use Sendzovo across the systems and workflows that keep your business running.
Power account notifications, product updates, authentication messages and other application-driven communication.
Deliver order confirmations, receipts, shipping notifications and customer account messages.
Connect ERP, CRM, portals and internal applications to dependable transactional email infrastructure.
Build customer-facing applications that require reliable and observable email delivery.
Enterprise applications often send different types of email. Separating application-generated messages from other communication helps teams manage their workflows more clearly.
Send messages triggered by application or customer activity.
Validate recipient addresses before they enter your sending workflow.
Give developers the interfaces they need while keeping email delivery connected to the systems that operate your applications.
Integrate transactional email directly into application code using authenticated HTTP requests.
Connect existing software and infrastructure that already supports standard SMTP.
Send delivery events into your own applications and backend workflows.
Give engineering teams implementation guidance for integrating Sendzovo into their applications.
Introduce Sendzovo into your existing email workflow through a clear path from domain setup to production monitoring.
Determine which applications and transactional workflows will use Sendzovo.
Configure the DNS records required for the domains your applications will use to send email.
Integrate through the REST API or connect existing applications through SMTP.
Connect email events and webhooks to the systems that need visibility into delivery activity.
Test your integration, recipient handling and application workflows before moving production traffic.
Monitor delivery activity, handle failures and maintain suppression and authentication workflows.
Common questions about integrating Sendzovo into production applications and email workflows.
Yes. Sendzovo is designed to provide transactional email infrastructure for applications that send messages such as authentication emails, notifications, receipts and other event-driven communication.
Yes. Applications that support SMTP can connect to Sendzovo using the standard SMTP connection instead of implementing the REST API.
Yes. Applications can send transactional email through the Sendzovo REST API using authenticated requests.
Yes. Sendzovo provides email verification checks that can be used before addresses enter your sending workflows.
Yes. Webhooks can be used to connect supported email events with your own application and operational workflows.
Sendzovo provides bounce and suppression functionality to help prevent repeated sending attempts to recipients that should no longer receive messages.
Not necessarily. Existing SMTP-compatible applications can connect through SMTP, while applications that need deeper integration can use the REST API.
