Custom domain email inbox
Your campaign replies,
one dashboard away.
Inbox is Builderify's inbound email system. Adding a sending domain gives you real mailboxes on it — replies land in the dashboard, thread themselves, and the machine-generated mail nobody wants to read is filed away separately.
From MX record to
your dashboard.
No IMAP. No POP3. No passwords. Just point your DNS and emails flow in via webhook.
DNS
Point your domain's MX record to mta-pool.builderify.net
Mail Server
KumoMTA receives and validates the recipient exists
Webhook
Email converted to JSON and forwarded to Laravel API
Dashboard
Email appears in your Inbox in real-time
Every mailbox.
One view.
Aggregate emails from all your domain inboxes into a single chronological feed. Filter, search, and manage everything from one place.
Multi-inbox aggregation
All domain inboxes in a single chronological feed. Filter by specific inbox anytime.
Search & filter
Find emails by sender name, address, or subject line. Visual read/unread indicators.
Auto inbox creation
Adding a sending domain in Broadcast automatically creates a matching inbox.
Four kinds of mail.
Only one needs you.
Inbound mail is sorted by what it actually is, so real replies are never buried under delivery reports.
Regular
Genuine replies from real people. These are the ones that appear in your unified view and wait for an answer.
Bounce
Delivery failures, captured and matched back to the contact so the address can be flagged instead of retried forever.
Unsubscribe
Opt-out requests sent by mail, including one-click unsubscribes from mailbox providers, recorded against the contact.
Abuse
Spam complaints routed straight to their own mailbox, so you see reputation problems while they are still small.
Hide what you never read
System mailboxes can be kept out of the unified view while still collecting everything in the background.
Reply as the right sender
When you answer, you choose which verified sending domain the message goes out from — the thread stays intact.
Mark, search, clear
Read and unread states, full-text search, per-mailbox filtering, and a single action to clear a backlog.
Full threads.
Reply without switching tools.
Click any email to see the entire conversation thread — every inbound message and every reply you've sent, in chronological order. Reply directly from the dashboard.
Smart domain selection
Replies automatically use the sending domain that matches the inbox — proper From/DKIM alignment.
Email threading headers
In-Reply-To and References headers ensure replies thread correctly in Gmail, Outlook, and other clients.
Domain override
Override the sending domain with any of your active domains using the dropdown selector.
Quoted original
Original message is automatically quoted in your reply for full context.
Safe by default.
Clean by schedule.
HTML Sanitization
Every inbound HTML email is sanitized before display. Script tags, style injections, event handlers like onclick and onerror, and dangerous protocols are all stripped — only safe tags pass through.
MIME Decoding
Quoted-printable and Base64 content decoded automatically. Multipart messages parsed into text/plain and text/html parts.
30-Day Auto-Cleanup
A daily scheduled task removes emails older than 30 days. No manual maintenance, no storage bloat.
Inbox Creation
Inboxes are created automatically when you add a sending domain in Broadcast, or manually from the Inbox management page. Each inbox just needs one MX DNS record.
Inbox doesn't work alone.
It is the reply loop that closes the cycle Broadcast starts and your lead lists feed.
Broadcast
Adding a sending domain auto-creates a matching inbox. Campaign replies flow in.

Bounces and opt-outs are matched back to the contact, so your lists clean themselves.

Inbox, before you ask.
Adding a sending domain in Broadcast automatically creates a matching inbox, and there is no separate line for receiving mail on the rate card. Every account starts with 250 free Usage Credits each month, and if you need more, one-time packs start at $9, purchased credits never expire and there is no monthly fee.
No. Replies land in your Builderify dashboard and you answer them there, with threading headers so the conversation still threads correctly in the recipient's Gmail, Outlook or other client. Setup is one MX record pointed at mta-pool.builderify.net, with no IMAP, POP3 or passwords.
Inbound mail is sorted into four mailbox types: regular replies, bounces, unsubscribes and abuse reports. Bounces and opt-outs are matched back to the contact so your lists clean themselves, and spam complaints go to their own mailbox so reputation problems show while they are still small.
A daily scheduled task removes emails older than 30 days, so there is no storage to maintain. Every inbound HTML email is also sanitized before display, with scripts, event handlers and dangerous protocols stripped out.
