Everything you need to send responsibly
The features that protect your sender reputation aren't add-ons here — they're the foundation.
List management
Consent-tracked contacts with CSV import that records how and when each person opted in. Suppressed addresses are skipped on import.
Analytics
Delivered, open, click, bounce, complaint and unsubscribe rates per campaign — updated in real time from provider webhooks.
Automation
Schedule campaigns and send through a throttled, retryable queue so you never burst — bursting is what hurts your reputation.
How it works
From zero to inbox in three steps
- 01
Verify your domain
Add a sending domain and we generate the exact SPF, DKIM and DMARC records. One click verifies them — sending stays blocked until it's green.
- 02
Import your audience
Bring contacts in manually or by CSV, attesting consent and capturing the source. Anyone on your suppression list is filtered out automatically.
- 03
Send & measure
Compose with an auto-injected unsubscribe link, send through a throttled queue, and watch opens, clicks and bounces land in your dashboard.
High inbox placement is earned, not tricked
These rules are the product's value. They're enforced for every account, every send.
1-click unsubscribe
Every email carries a working one-click unsubscribe and a List-Unsubscribe header. Sending is rejected if it's missing.
100% consented
Every contact has a consent record — how and when they opted in. No anonymous bulk dumping.
Auto suppression
Bounces and complaints are added to your suppression list automatically and can't be silently re-enabled.
