Built for Startups That Build With Their Own Money

Keep your email infrastructure simple, reliable and cost-conscious while you focus on building a product customers want.

Designed for Lean Startup Teams

Sendzovo fits teams that want useful email infrastructure without building a large internal email operation.

Solo Founders

Keep product infrastructure manageable when you are building and operating the product yourself.

Small Engineering Teams

Integrate email without assigning significant engineering capacity to building and maintaining delivery systems.

Self-Funded Products

Keep infrastructure decisions focused on practical requirements and responsible operating costs.

Bootstrapped SaaS Products

Build authentication, notifications, billing and other transactional email workflows around your SaaS product.

Ship More Without Building More Infrastructure

When your team is small and every expense matters, unnecessary infrastructure becomes a distraction.

Keep Costs Predictable

Use the email infrastructure you need without spending engineering time building and maintaining your own delivery stack.

Stay Lean

Let your developers focus on product development instead of operating mail servers and delivery infrastructure.

Launch Faster

Connect your application through an API or SMTP and start sending transactional messages without a lengthy infrastructure project.

Grow at Your Own Pace

Build the email workflows you need today and add more capabilities as your startup grows.

Built for Bootstrapped Economics

Keep your email stack focused on what your product actually needs instead of paying for infrastructure you do not need.

Start With What You Need

Begin with transactional email through the API or SMTP and add verification and event-driven workflows as your requirements grow.

Avoid Building From Scratch

Building and maintaining email delivery infrastructure takes engineering time that could otherwise go toward your product.

Reduce Tool Sprawl

Keep transactional email and email verification within one platform instead of stitching together multiple services.

Spend Engineering Time Carefully

Use your limited engineering capacity for features that directly improve your product and customer experience.

The Email Tools You Actually Need

Sendzovo brings delivery and verification into one straightforward platform.

Transactional Email API

Send emails directly from your application using a simple REST API.

Webhooks & Events

Connect delivery events to your application and automate actions based on email activity.

delivered → bounced → complained

Keep Your Email Stack Lean

Avoid turning a simple product requirement into a collection of separate email services.

Transactional Email

Send application-generated emails through the REST API or SMTP.

Email Verification

Validate addresses before they become part of important product workflows.

Delivery Events

Connect supported delivery events to your application through webhooks.

Suppression Workflows

Prevent future delivery attempts to recipients that should no longer receive messages.

Essential Email for Your Product

Handle the email workflows your customers depend on without overcomplicating your application.

User Authentication

Deliver the emails required to create and secure customer accounts.

  • Email verification
  • Password resets
  • Login notifications
  • Security messages

Customer Notifications

Keep users informed about important activity in your product.

  • Account updates
  • Workflow notifications
  • Service alerts
  • Product activity

Billing & Payments

Deliver important transactional communication around payments and subscriptions.

  • Invoices
  • Receipts
  • Payment confirmations
  • Subscription notifications

Onboarding

Build automated email workflows that help new users get started with your product.

  • Welcome emails
  • Getting-started messages
  • Account confirmations
  • Product notifications

Don't Become Your Own Email Provider

Running email infrastructure yourself can quickly turn into another operational responsibility for a small team.

No Mail Server to Maintain

Avoid spending development time maintaining your own SMTP infrastructure and delivery systems.

No Delivery Stack to Build

Start with an established API or SMTP integration instead of creating your own email delivery layer.

No Separate Verification Service

Verify addresses through the same platform you use for transactional email.

Less Operational Overhead

Keep your infrastructure focused on the product instead of maintaining systems that are not part of your core business.

Make Every Email Count

For a lean startup, unnecessary email attempts can mean wasted resources and avoidable delivery problems.

Verify New Addresses

Check addresses during signup or before adding them to important communication workflows.

Clean Customer Data

Validate existing lists before sending product or customer communication.

Detect Disposable Emails

Identify disposable email domains before allowing them into workflows where a permanent address is important.

Reduce Avoidable Bounces

Use verification results to make better decisions before attempting delivery.

From MVP to Production Without Overbuilding
