Every mailbox's replies, one screen
Replies from every campaign and mailbox funnel into a single view. Conversations stay threaded, you can search and filter across everything, mark items read or unread, and archive what's done. You stop hopping between individual email accounts to figure out who wrote back.




Lambda Group
Nothing scattered across accounts
Responses from every mailbox and campaign stream into a single inbox — no more account-hopping.
Full email threads with lead data and campaign context attached, so you never lose track of where things stand.
Find any reply instantly, or filter by campaign, mailbox, or status to zero in on what matters right now.
Track what still needs attention and archive what doesn't, keeping the inbox clean as you go.
Answer faster without switching tabs
Every response from every connected mailbox shows up in your unified inbox automatically, with unread counts badged so nothing slips past you.
Click into any reply and see the whole thread — your original message, their response, and every follow-up, all in context.
Search across every reply, filter by campaign, mailbox, or status, mark conversations read or unread, and archive what you've handled.
Everyone works from the same inbox. Unread badges make it obvious what still needs a response, so nothing falls through the cracks.
Handle every client's replies from one place, filtering by campaign when you need to focus on a single account.
Thread view surfaces the entire conversation history, so you respond with context instead of digging through individual mailboxes first.
Built like an inbox, not a timeline
One inbox, full search, nothing missed
Most tools leave replies scattered across separate mailbox accounts. Sendbox consolidates every reply into a single unified inbox with threading, search, filtering, read/unread tracking, and archiving. Missing a response gets a lot harder.
Threads that keep their context
Every reply shows the full email thread — your message, their response, every follow-up after it — alongside the campaign name and lead data. Nobody on your team has to ask which campaign a reply came from.
Search and organize at any scale
Keyword search runs across every reply. Filter by campaign, mailbox, or read/unread status, mark conversations as handled, and archive finished threads to keep the inbox tidy.
