Our take on Peeker
Peeker's differentiator is self-healing infrastructure: it monitors deliverability in real time and automatically swaps out burned or underperforming Google Workspace and Azure inboxes without stopping your campaigns or requiring a new subscription. Setup is fast (2–48 hours) and the API is included on all plans, so the operational story is strong if mailbox churn is your pain point.
What's missing is disclosure. Peeker makes no mention of pre-warming anywhere, and key fields — IP model, monthly-vs-annual billing, exact warmup status — simply aren't published, which lowers confidence on those points. There's also a 30-day minimum commitment and no Trustpilot or G2 presence to corroborate satisfaction. It's clearly a real, functioning product; just go in expecting to handle warmup yourself and to verify the infrastructure details directly.
