Where HotHawk wins
The same inbox, over any sender, for less.
MasterInbox can only manage replies, so it always needs a sender underneath. HotHawk’s Master Inbox works the same way over your existing sender, and it can send too, at a third of the price.
Use it over your own sender
You do not have to send through HotHawk to use the Master Inbox. Connect the mailboxes you already send from, and it unifies and routes the replies no matter what sent them. Plenty of our clients run it exactly this way, as a reply layer on top of their existing stack.
Or let it send too
The difference from MasterInbox is that HotHawk can also do the sending: a full sequencer with warmup on real Google and Microsoft inboxes and automatic rotation. Use just the inbox, or consolidate the sender into it as well. Your call.
A third of the price
HotHawk is $97 a month. MasterInbox starts at $299 a month for the reply layer, and it cannot send, so a sequencer sits underneath it as a separate cost. Same reply-inbox job, a lot less money.
One place if you want it
Because HotHawk can send as well as manage replies, you can run your whole outreach in one tool, or keep your sender and use HotHawk purely for the inbox. MasterInbox only offers the second half.
Where HotHawk wins
A Master Inbox that misses nothing.
Both tools give you one inbox for replies. HotHawk’s catches the ones a reply layer can miss, routes them to your team, and works whether HotHawk sent the campaign or your own sequencer did.
Misses no replies
Catches the forwarded replies, the CC’d colleagues and the people you never emailed directly, across every mailbox you connect.
Routes to your team
Round robin and mailbox groups assign every reply the moment it arrives, so nothing sits unowned and no one answers twice.
Labels sort themselves
Local AI labels each reply out of the box, interested, out of office, not now, so the positive ones rise to the top without anyone tagging by hand.
Works with your stack
Connect your mailboxes over IMAP or OAuth and it handles the replies whether HotHawk sent them or your existing sequencer did.
Where MasterInbox wins
MasterInbox has a real job to do.
Where MasterInbox is genuinely ahead is the breadth of its native integrations. It connects out of the box to a wide set of specific sequencers and LinkedIn tools, HeyReach, Expandi, Aimfox and more, so if your outreach runs across several of those exact tools and you want deep, pre-built connectors to all of them in one reply inbox, MasterInbox covers more of them than we do.
HotHawk pulls email replies from any mailbox you connect, and integrates natively with EmailBison and HeyReach, which covers most teams. But we will be straight: on sheer number of pre-built LinkedIn-tool connectors, MasterInbox has the wider list. Where we win is doing the same reply-inbox job over any sender, plus the option to send, for a third of the price.

FAQ
HotHawk vs MasterInbox questions.
What is the difference between HotHawk and MasterInbox?
MasterInbox is a reply-management layer: it pulls replies from your tools into one inbox, but it does not send email, so you always run a separate sequencer underneath. HotHawk does the same sequencer-agnostic reply inbox, connect your own mailboxes and it unifies the replies whatever sent them, and it can also send if you want it to. Same reply job, plus the option to consolidate the sender, for a third of the price.
Do I have to use HotHawk to send in order to use its Master Inbox?
No. The Master Inbox is sequencer-agnostic. You connect the mailboxes you already send from, over IMAP or OAuth, and HotHawk unifies and routes the replies regardless of what tool sent the campaigns. A lot of our clients use HotHawk purely as the Master Inbox on top of their existing sender, and add the sending side later, or never.
Does MasterInbox send cold email?
No. MasterInbox is a unified inbox for managing replies from other tools; the sending happens in whichever sequencer you connect to it. So it is always an add-on cost on top of your existing sender. HotHawk can work the same way as a reply layer, and it can also send, so it does the whole job in one tool if you want.
Is HotHawk cheaper than MasterInbox?
Yes. HotHawk is $97 a month. MasterInbox is from $299 a month for the reply layer alone, and since it cannot send, a sequencer sits underneath it as a separate cost. For the same sequencer-agnostic reply inbox, HotHawk is a third of the price, and it can send too.
When is MasterInbox the better choice?
Where MasterInbox is genuinely broader is native, pre-built integrations. It connects to a wide set of specific sequencers and LinkedIn tools out of the box, including HeyReach, Expandi and Aimfox. HotHawk pulls email replies from any mailbox you connect, and integrates natively with EmailBison and HeyReach, but if your stack leans on several of those exact LinkedIn tools and you want deep native connectors to all of them, MasterInbox covers more of them.
Can I move from MasterInbox to HotHawk?
Yes, and it usually simplifies your stack. Connect your mailboxes to HotHawk over IMAP or OAuth and the Master Inbox takes over the replies straight away, whatever you send with. From there you can keep your existing sender, or move the sending into HotHawk too and drop a tool. Either way you replace a $299 reply layer with a $97 one that can also send.
