Why Sonar

Built for outreach.
Not for everything else.

Heavy CRMs were designed for enterprise sales orgs. Sonar is designed for operators who want results, not roadmaps.

⚠ Heavy CRM

Complex tools that slow you down

✕
Multi-week onboardingSetup requires specialists, training sessions, and data migration before you can send a single email.
✕
Workflow lock-inPipelines, stages, automations and triggers that require constant maintenance even for simple outreach.
✕
Bloated pricingPer-seat pricing, add-on modules, and mandatory enterprise tiers just to send a basic campaign.
✕
Deliverability blind spotsNo visibility into provider matching or rotation without additional paid integrations.

Deliverability

Built to land in the inbox.

Deliverability signals that most outreach tools hide behind expensive add-ons — included by default in Sonar.

🔀
Mailbox rotation
Distribute sends across multiple connected mailboxes automatically to reduce per-inbox volume and sending risk.
Active across 2 mailboxes
🎯
Provider matching
Sonar detects the recipient's email provider and routes sends from matching provider mailboxes for better inbox placement.
Gmail → Gmail · Outlook → Outlook
⏰
Best-time suggestions
Timing recommendations based on the recipient's timezone and location to optimise open rates without guesswork.
Timezone-aware scheduling

Connection testing
