One unified inbox for every cold email reply
Revbound pulls replies from all your sequencer accounts into one list, sorts them with AI, drafts or sends the answer and books the meeting on your calendar.
Revboundfrom $49/mo
A unified inbox brings replies from many mailboxes and tools into one place, so nobody has to log in to each account to find the interested leads.
- Revbound is a unified inbox built for cold email replies, not a general email client.
- It connects to Instantly, Smartlead, Email Bison, PlusVibe, SendKit and ArcSend, and to Cal.com or Google Calendar for booking.
- AI labels each reply, drafts the answer and offers free calendar times. On Agency and Connector, interested leads are answered within 5 minutes.
- Plans are $49, $99 and $149 a month, month to month, with the AI included and a 3-day free trial.
- It does not handle LinkedIn, SMS or voice, and it has no CRM sync.
Why cold email teams need a unified inbox
Cold email at volume means many sending mailboxes, often across more than one sequencer and more than one client. Each tool has its own reply view. Interested replies end up scattered across tabs, and the slowest step in the whole funnel becomes someone finding them.
Replies hide behind logins
When replies live in six accounts, someone has to check six places, several times a day. Leads who said "yes, send times" can wait hours for an answer.
Out-of-office and referral replies get dropped
An auto-reply that says "back on Monday" or "talk to my colleague" is a real lead. In a crowded inbox they are the first to be ignored.
Agencies cannot prove the work
Clients ask what happened to the replies. Without one list and a record of each meeting, the answer is a screenshot hunt.
What Revbound's unified inbox does
Every sequencer reply in one list
Connect your accounts in Instantly, Smartlead, Email Bison, PlusVibe, SendKit or ArcSend. Replies from all of them land in one Unibox, grouped by client when you run an agency.
AI sorting
Each reply is labeled, for example Interested, Meeting Scheduled or Out Of Office, so the replies that need an answer now are at the top.
Drafted or automatic answers
On Solo, Revbound drafts each answer for you to read and send. On Agency and Connector, it answers interested leads in the same thread within 5 minutes, and you can take over at any point in those 5 minutes.
Meeting booking
Answers offer times that are free on your Cal.com or Google calendar, and Revbound books the meeting when the lead says yes.
Follow-ups that run themselves
Out-of-office follow-ups write back when the lead returns, referral follow-ups contact the person the lead pointed to, and on Agency and Connector, quiet leads get follow-ups every 3 to 4 days for 2 months.
Unified inbox vs your sequencer's own inbox
| Sequencer inbox | Revbound unified inbox | |
|---|---|---|
| Replies from several sequencers | No, one tool at a time | Yes, Instantly, Smartlead, Email Bison, PlusVibe, SendKit and ArcSend |
| Several clients in one view | Depends on the tool and plan | Yes, up to 5, 10 or unlimited clients by plan |
| AI drafts with free calendar times | Varies by tool | Yes, on every plan |
| Automatic booking | Varies by tool | Yes, Cal.com or Google Calendar |
| Client reports with proof of meetings | Rarely | Yes, on Agency and Connector |
Sequencer features change often. Check your own tool before deciding; Revbound works alongside it rather than replacing it.
What the unified inbox costs

A reply means one inbound email the AI reads. Emails you send do not count. See the full pricing page for every feature by plan.
Who it is for, and who it is not for
- Good fit: cold email agencies and outbound teams running campaigns across several mailboxes, sequencers or clients, who want one place to answer replies and book meetings.
- Not a fit: teams that need LinkedIn, SMS or voice replies in the same thread, or replies synced to a CRM. Revbound is email only and has no CRM sync.
- Not a sender: Revbound does not send cold emails. Your campaigns keep running in your sequencer.
