Every inbox you own, answered by an agent that never sleeps
Connect email, SMS, social DMs, cold-outreach mailboxes and your website chat in minutes. ReplySetter syncs every new message, hands it to the agent assigned to that inbox, and replies on the same channel, in the same thread, inside your business hours.
A closer look at Omnichannel inbox
Nothing slips through, even when a provider hiccups
Each provider is synced the way it was designed to be read: Gmail history IDs, Outlook delta links, GoHighLevel webhooks with a safety sync behind them, and the SmartLead and Instantly master inboxes. New inbound messages queue an agent run, debounced per thread so a burst of three texts gets one thoughtful answer instead of three rushed ones.
- GoHighLevel webhooks start a reply within seconds; idle sub-accounts aren't polled every minute
- Gmail and Outlook resume from their last checkpoint, with a full resync if the checkpoint expires
- History is backfilled on first connect for context, and agents never reply to backfilled mail
- 15-second per-thread debounce turns message bursts into a single reply
Replies land where the conversation lives
An SMS gets an SMS back. A WhatsApp message gets a WhatsApp reply. A Gmail thread gets a properly threaded reply with In-Reply-To and References headers. Cold-email leads are answered from the exact mailbox they wrote to, so deliverability and context stay intact.
- Threaded email replies, drafts, labels, categories, archive and mark-as-read
- GoHighLevel replies on SMS, Email, WhatsApp, Facebook, Instagram and Live chat
- SmartLead and Instantly replies from the lead's own mailbox, with lead categories and interest statuses
- Filter the Inbox page by mailbox, campaign, tags and lead status
Business hours and filters that behave like a real team
Give every inbox its own opening hours and timezone. After hours, choose whether replies wait for opening, go out anyway, or send a short holding message now and the real answer at opening. Tag filters decide who an agent answers, and emoji-only messages or SMS reactions like “Liked ‘See you at 5’” never trigger a reply.
- Per-inbox hours in the inbox's own timezone
- Holding message now, full answer when you open
- Only answer contacts with certain tags, or never answer others
- Reactions and emoji-only messages are recognised and ignored

Omnichannel inbox: common questions
Can one agent answer several inboxes?
Yes. Each inbox is assigned one agent, and the same agent can be assigned to as many inboxes as you like, across providers.
Will it reply to my old emails when I connect?
No. Recent history is backfilled so the agent has context, but agents never run on backfilled messages.
What happens when three texts arrive in a row?
Runs are debounced by 15 seconds per thread, so the agent reads all three and sends one reply.
Can I limit which SmartLead or Instantly mailboxes are handled?
Yes. After connecting a workspace you can pick exactly which mailboxes the agent handles.
