For developers
Ship transactional email with clean primitives, provider flexibility, and traceable delivery events.
API-first sending with webhooks and auditability
Provider abstraction across SES, SendGrid, MailerSend, Gmail, SMTP, and more
Operational visibility without bolting on separate tooling
For marketers
Build campaigns, manage lists, and understand engagement from the same system your app already trusts.
Campaign design and templates in one place
Audience management and CSV import without workflow sprawl
Performance monitoring across opens, clicks, bounces, and failures
Less patchwork. Better visibility. One system of record for email.
Most teams run transactional email in one tool and marketing email in another, then spend their time reconciling data, permissions, and failure states across both. Buzzz puts it all in one system instead.
One control surface
Transactional traffic, campaigns, templates, and audience operations all live in the same operating model.
Signal, not noise
Track delivery, engagement, and failures with enough context to act without drowning in vanity dashboards.
Trust built in
Rate limiting, webhook ingestion, bounce handling, and API keys are treated as product fundamentals.
Setup, sending, and reporting in one flow.
Configure once
Connect your sending domain, API keys, and preferred providers from a single settings surface.
Send from code or canvas
Use the API for transactional flows or launch campaigns from the visual designer and templates.
Respond with confidence
Monitor opens, clicks, bounces, and failures in one place instead of reconciling across vendors.
Bring delivery, campaigns, and performance into the same workspace.
Set up sending infrastructure, launch marketing work, and keep both sides of the team aligned without adding another platform to manage.
