Trailblaze plugs straight into the email platforms, CRMs, and forms your team already runs — so verification happens where your data lives instead of becoming one more disconnected stop.
Ready-made connections cover more than 40 platforms. These are the ones teams reach for most — and we keep connecting new services.
Don't see your platform? The Express Lane API connects to anything.
Read the API docsEvery ready-made connection runs on the same Express Lane API you can call yourself. One request per address, the same five-stage result, and no waiting on a roadmap.

}Once your platform is connected, pull any list across in a single click — no exporting, no reformatting, no CSV round trip. When verification finishes, the result goes straight back: unsubscribe or delete every bad and risky address without leaving the tool your team already works in.
Scheduled re-verification watches the lists you nominate, checks new contacts on the cadence you set, and clears bad addresses out of your account before the next send goes out. Your list stays sendable between campaigns instead of only on the day you remember to clean it.
Every file runs the same five-stage route, and we publish the head-to-head results against the other services so you can check the number rather than take it on trust.
See the guaranteeVerification Miles cover single real-time checks, connected imports, and bulk runs from the same balance. Pick monthly or pay as you go — no charge for records we cannot verify.
