What is deliverability tracking?

Deliverability tracking allows you to track whether your domain and sending inboxes are healthy, underperforming, or burned. We use a combination of historical and recent reply rate data per domain along with some formulas to accurately identify whether or not a domain is burned.

How fast can I get my inboxes up and running?

We promise a delivery time of under 48 hrs but many of our orders are done just within 2–4 hrs after placing an order.

How many emails do you recommend I send per day per inbox?

For best results 3 emails per inbox (75 inboxes per domain) is what we recommend, but most of our users send 6 emails per inbox per day for maximum sending volume.

What happens if my inbox gets flagged or breaks?

If your inboxes get flagged for spam we offer premium domain swaps, allowing you to swap your current inboxes for new ones without having to buy another subscription or stopping your current sending volume.

How is Peeker different from other inbox providers?

We offer domain level deliverability tracking so you can monitor your inboxes if they are underperforming or not and we offer premium swaps that will be coupled with automated swaps so you don't even have to worry about managing your infra anymore.

Can I cancel anytime?

There is a required 30 day period for your subscription where we do not allow early cancellations for prorated amounts. As long as you cancel before your renewal then yes you can cancel whenever you like.

Problems With Deliverability

Great Outreach Means Nothing If It Lands In Spam

Most teams only think about deliverability after results drop. Without the right analytics insights, great outreach gets throttled, filtered, or sent straight to spam, quietly killing replies.

Deliverability Guesswork

With limited deliverability visibility, you often fly blind when trying to observe whether your emails are landing in spam or not.

No Insights = No Optimization

Without accurate data on inbox reply rates, campaign optimization becomes guesswork and you can't improve performance.

Poor Campaigns, Weak Results

If campaigns aren't backed with real inbox data, you'll burn time and campaign budget with less return.
