The Missing Layer
In Instantly
Instantly manages campaigns, not inbox stability. At higher volume, you need more than sequencing, and Instantly lacks the monitoring + automation that keeps inbox pools healthy over time.
Limited Deliverability Visibility
Instantly can show results, but it doesn't give you deep inbox insights (placement dips, reputation weakening, rising bounce rates) that warn you before campaign performance drops.
Manual Inbox Rotation
When an inbox starts underperforming, Instantly won't automatically swap or replace it so you end up manually rotating inboxes.
No Self-Healing
Instantly doesn't have self-healing features for when inbox health starts slipping (reply rate drops, bounces rise, warm-up weakens).

Try Peeker For Instantly
No more daily checks, manual swaps, or panic fixes. Inbox infrastructure runs in the background while your campaigns keep running smoothly.
001
Advanced Deliverability Tracking
See what's actually happening behind your sends: inbox health, performance shifts, and risk trends, organized in one clear dashboard.
002
Automatic Inbox Swaps
When an inbox gets burned, Peeker automatically swaps it for a fresh and healthy one. No manual intervention, no downtime, no paused campaigns.
003
Never Worry About Starting Slow and Steady
Experts preach that new inboxes should begin with very low sending volumes and gradually increase it over time. We provide already warmed-up inboxes so you can hit the ground running with high volumes for your campaigns.
Done-For-You Setup, Ready to Send
Once you connect Instantly to Peeker, warm-up is preconfigured automatically with a clear log of when each inbox was added. Peeker also configures your DNS and sending settings, so every inbox is fully set up and ready to send.
