Unibox
Every reply from every mailbox, in one inbox.
Twelve mailboxes should not mean twelve tabs. The Unibox collects every reply your campaigns get, sorts them by what the person actually said and lets you answer in the same thread, from the mailbox they wrote to.
All mailboxes in one place · Sorted by intent · Replies stop the sequence
One place
Interested, booked, not now. Sorted before you look.
Each reply gets a clear label, so the people who want to talk sit on top and out of office notes never crowd your morning.

Your answer goes out in the same thread from the same mailbox, and the follow ups for that person stop on their own.

How to build a targeted B2B list by industry and seniority
A field guide to list definition: why industry filters lie, why seniority is a pattern set rather than a dropdown, how to size a list backward from sending capacity, and the preview-first workflow that catches bad filters before you pay for them.
VerificationJune 10, 2026
Why verified-at-export beats verified-at-collection
B2B contact data decays the moment it's collected. Here's why the timing of verification matters more than the method, what an SMTP probe actually proves, and how pay-per-valid pricing changes the buyer's math.
