Email campaigns that actually reach the inbox
Verify your domain, import your list, and let automatic warm-up, adaptive throttling, and reputation guardrails do the hard part of deliverability.
- SPF / DKIM / DMARC verification
- Automatic warm-up
- Bounce & complaint guardrails
- RFC 8058 one-click unsubscribe
Deliverability first, everything else second
Every part of the platform is built around one goal: your email landing in the inbox without burning your domain's reputation.
Domain verification
We generate your SPF, DKIM (2048-bit), DMARC, and bounce-domain DNS records, then check them automatically and keep re-checking. Sending only opens up once your domain verifies.
Gradual warm-up
New domains start at 50 emails a day and ramp up stage by stage, with each stage held for at least two days — and a slower ramp for stricter providers like Microsoft.
Reputation guardrails
Bounce and complaint rates are watched continuously. When they climb, sending backs off or pauses automatically — protecting your domain before providers penalize it.
Consent-first imports
Streaming CSV imports with a required consent attestation. Unsubscribed, bounced, or complained contacts are never resurrected by an import — suppressed addresses stay suppressed.
Built-in compliance
Every message carries RFC 8058 one-click List-Unsubscribe headers and links to a hosted unsubscribe page. Suppressions are enforced when the audience is built and again right before each send.
Open & click analytics
Per-campaign opens, clicks, bounces, and unsubscribes, plus daily reputation rollups per sending domain, so you can see how each send actually performed.
How it works
- 1
Verify your sending domain
Add the DNS records we generate for you. Checks run automatically and your domain flips to verified once SPF, DKIM, and DMARC all pass.
- 2
Import your contacts
Upload a CSV — it streams in at any size. You attest to how consent was collected, and existing unsubscribes and bounces are always respected.
- 3
Build your campaign
A four-step wizard: details, content with merge tags, audience selection, and a review step with prechecks before anything is queued.
- 4
Send with guardrails on
Warm-up caps and throttling pace the send, guardrails watch bounces and complaints, and opens and clicks stream into your analytics.
