Cody is among the heaviest senders on the platform, routinely testing what Sendbox can handle. His experience running mailboxes by the thousand shows us exactly what power users need at that scale.
Contributions
Advanced Webhook Options
Suggested finer-grained webhook controls, firing only on positive replies, triggering on tag changes, and capping delivery to once per lead. We built all three.
Inbox Live Refresh
Pushed for the inbox to update in real time rather than making users refresh to catch new messages. Replies now show up the instant they arrive.
Conversations CSV Export
Asked for a way to pull complete conversation threads out of Unibox as CSV. That data is now exportable whenever you want it.
Bulk Outlook/Azure Import
Made the case for native support to bulk import thousands of Outlook and Azure mailboxes at once, a huge unlock for teams operating at scale.
Nested Spintax Support
Noticed we needed spintax that could nest inside other spintax for more natural-sounding variation. We shipped it the same day.
