Main Dashboard — campaigns + analytics
Why teams switch
Simple, fast, predictable. You ship emails — not configuration.
Fast campaigns
Templates or HTML. Schedule and send without friction.
Clean Email API
Transactional email via simple HTTP — no messy SDKs.
Reputation guardrails
Validate + suppress risky addresses. Pause on spikes.
Realtime analytics
Opens, clicks, bounces, complaints — one place.
Safer sending defaults
Warm-up batches and sensible limits to protect domains.
Built for builders
Docs-first, clear primitives, easy integrations.
Email Validator
Validate an email live
Syntax, MX, disposable, SMTP response — the same pipeline used before sending.
Try a real mailbox first, then a fake one to see SMTP rejection.
Clean lists before you send
Validate CSVs at scale, suppress risky addresses automatically, and protect your domain reputation.
Best flow
Import → Validate → Warm-up batch → Scale
