First, the why

Why teams look past MasterInbox.

MasterInbox does a real job, one inbox over many tools. These are the three things that send people looking for something simpler or cheaper.

It is a reply layer, not a sender

MasterInbox unifies replies but does not send, so you run and pay for a separate sequencer underneath it. For a lot of teams that is two tools and two bills where one would do.

The price is on top of your sender

MasterInbox starts at $299 a month for the reply layer alone, before the cost of the sequencer it sits on. A cold email tool with the inbox built in, or a plain shared inbox, often works out cheaper.

You may just want a team inbox

If what you actually need is several people working one inbox, a general shared inbox like Front, Missive or Hiver does that for a fraction of the price, without the outbound machinery.

The list

The 5 best MasterInbox alternatives, ranked.

1

HotHawk

from $97/mo Our pick

A Master Inbox that catches and routes every reply, whether you send through HotHawk or keep your own sender, for a third of MasterInbox’s price.

Where it wins. A unified inbox that catches every reply, including forwarded and CC’d ones and people you never emailed directly, with round robin and mailbox-group routing and local AI labelling out of the box. It is sequencer-agnostic, connect your own mailboxes and it works over whatever you send with, just like MasterInbox, and it can also send if you want it to. So you get the reply inbox for $97 a month, not a $299 reply layer that needs a separate sequencer under it.

The trade-off. HotHawk is built for cold email replies, not general team or support email. If what you want is a shared inbox for collaborating on inbound mail, the tools below fit that job better than we do.

2

Front

from $25/seat/mo

The most polished shared inbox, strong on collaboration and CRM-embedded workflows.

Where it wins. A mature, multichannel team inbox, email, SMS, chat and voice, with assignment, internal comments and deep integrations. The default when several people work a shared address like support or sales together.

Where it falls short. It is built for collaborative inbound, not cold outreach. No sequencing, no warmup, no mailbox rotation, and per-seat pricing that climbs to $65 on the Professional plan most teams end up needing.

3

Missive

from $18/seat/mo

A clean, well-priced shared inbox with chat built onto every thread.

Where it wins. Team assignment, internal chat on each conversation, and multichannel support at a lower price than Front, with a free tier for a single user. A tidy choice for a small team sharing an inbox.

Where it falls short. Like Front, it is an inbound collaboration tool, not a cold email sender. There is no warmup, rotation or campaign side, so you would still need a separate tool to actually send.

4

Hiver

from $19/seat/mo

A shared inbox that lives inside Gmail, so your team never leaves the interface.

Where it wins. Assignment, statuses and helpdesk triage layered straight onto Gmail, with a free tier. Ideal for Google Workspace teams who want a shared inbox without learning a new app.

Where it falls short. Gmail and Google Workspace only, so Outlook teams are out, and it is aimed at support and triage rather than cold email, with no sending, warmup or rotation.

5

Help Scout

from $25/user/mo

A support-first shared inbox and help desk, well loved by small support teams.

Where it wins. A simple, friendly inbox with saved replies, a knowledge base and reporting built for customer support. Strong if the shared inbox you want is really a support desk.

Where it falls short. It is squarely a support tool, so it is the furthest from cold outreach here, no sending, sequencing or deliverability features at all.

How we ranked these

Our method.

MasterInbox alternatives split into two camps, so we have been clear about which is which. For managing cold email replies, the job MasterInbox does, we ranked on whether the inbox is built into the sending, catches every reply, and routes to a team, at what price. For a plain team inbox, we weighed collaboration, channels and cost. Prices are each provider’s published rates as of July 2026.

HotHawk is our own product, and we have put it first for cold email replies, because it does the same sequencer-agnostic reply inbox MasterInbox does, over your own mailboxes, and can send too, for less. We have been straight that Front, Missive, Hiver and Help Scout are better if you want a general shared inbox for inbound, since none of them send cold email. No tool paid to be here, and there are no affiliate links.

FAQ

MasterInbox alternatives, answered.

What is the best MasterInbox alternative?

It depends what you want the inbox for. To manage cold email replies, HotHawk is our pick: it does the same sequencer-agnostic reply inbox, connect your own mailboxes and it works over whatever you send with, and it can send too, at $97 a month rather than a $299 reply layer that needs a separate sequencer under it. If you just want a shared inbox for a team, Front, Missive and Hiver are the leaders.

Is there a cheaper alternative to MasterInbox?

Yes. MasterInbox is from $299 a month for the reply layer, plus the sequencer underneath. HotHawk includes the sender and the Master Inbox for $97 a month all in. And the general shared inboxes, Missive from $18 a seat, Hiver from $19, Front from $25, are cheaper still if you do not need the cold email side.

What is the difference between a master inbox and a shared inbox?

A master inbox for cold email, like HotHawk’s or MasterInbox’s, is built to pull replies from many sending mailboxes into one place and route them, with labelling and campaign context. A general shared inbox, like Front or Missive, is built for a team to collaborate on one address, support or sales, for inbound email. They overlap, but one is made for outbound replies and the other for inbound collaboration.

Can a shared inbox like Front manage cold email?

Not really. Front, Missive and Hiver are excellent at collaborative inbound, but they do not send cold email, warm mailboxes or rotate sending, and they are not built to pull replies across a rotation of many sending inboxes. For cold outreach you want a tool built for it, which is why HotHawk sits first here.

Do I have to use HotHawk to send to get its Master Inbox?

No. The Master Inbox is sequencer-agnostic, so you can connect your own mailboxes and use it purely as the reply layer over your existing sender, exactly like MasterInbox but a third of the price. A lot of our clients run it that way. Or move the sending into HotHawk too and replace both tools with one. Your choice.
