The basics
What is an email sequencer?
An email sequencer is software that sends a planned, multi-step series of cold emails to each prospect automatically, then stops the moment they reply. Also known as a sales cadence, it turns one-off outreach into a repeatable campaign that follows up for you, so no lead goes cold because someone forgot to chase it.
HotHawk is a cold email sequencer built for deliverability. You design the steps and the timing once, and HotHawk runs the sending in the background: rotating your mailboxes, warming them up and following best practice on every send, so the deliverability fundamentals are handled for you.

Built for deliverability
Deliverability, done right.
The best campaign in the world is worthless in the spam folder. We enforce deliverability best practices out of the box.
Automatic inbox rotation.
Sends spread automatically across all your connected mailboxes, so no single account ever sends too much too fast and your volume stays under the radar.
Infrastructure that protects your reputation.
Sending runs across rotating IPs, with dedicated IPs and isolated infrastructure available when you scale, so your sender reputation stays in your hands.
Warmup against other high quality mailboxes.
Your mailboxes warm up against a pool of real Google and Microsoft inboxes, never SMTP accounts or bots, so your sender reputation builds where it counts.
How it works
What building a campaign looks like with us.
Everything you need to build, send and manage cold email at scale, in one place.
Build a multi-step campaign in minutes.
Lay out every step with A/Z variant testing, set the wait time between each and add as many follow-ups as you need. Drag, edit and launch, with no setup project to sit through.
Standard, Evergreen or Sub Sequences.
Choose the campaign type that fits the job: a standard Cold Email Campaign, an Evergreen Campaign that never turns off and keeps accepting new leads, or a Sub Sequence triggered after a reply.
Personalise every message.
Drop custom variables into each email for 1:1 personalisation at scale, so every prospect gets a message that feels written just for them.
Follow-ups that stop when the lead replies.
HotHawk watches for replies across every mailbox and pauses the sequence automatically, so a prospect is never chased after they have already answered.
A/Z testing to find what works.
Run up to 26 A/Z copy variants per step and let real reply data pick the line that performs best, then double down on the winner.
Set campaign sending priority.
When your mailboxes are running low on daily sending allocation, tell us which campaigns are critical so they get the sending capacity first.
Manage every reply in the master inbox.
Every response across your mailboxes arrives in one industry-leading master inbox, including the forwarded and CC'd replies a basic sequencer drops, so nothing slips past you.
Handle out of office replies in a click.
Spot out of office replies automatically and re-add the lead to the campaign now, later, or to a different one, so a temporary no never costs you the conversation.

Email sequencer FAQs
What is an email sequencer?
An email sequencer is software that sends a planned, multi-step series of cold emails to each prospect automatically and stops the moment they reply. It turns one-off outreach into a repeatable campaign, also known as a sales cadence, that follows up for you.
How does HotHawk improve deliverability?
HotHawk spreads your sends across all your mailboxes with automatic inbox rotation, runs on rotating IPs with dedicated infrastructure available, warms your mailboxes against a real Google and Microsoft pool, and enforces best-practice sending by default, including no open or link tracking.
What is the difference between an email sequence and a cold email campaign?
They describe the same thing from different angles. A sequence is the ordered set of steps a prospect moves through, while a campaign is the whole send: the list, the steps and the settings together. In HotHawk you build a campaign and the sequence of steps lives inside it.
How long should a cold email sequence be?
Most high-performing B2B sequences run three to six steps over two to four weeks. The first email usually pulls the biggest single response, and each follow-up adds more replies on top, so a few well-spaced steps beat a one-and-done send without tipping into spam.
Can I A/B test my cold emails?
Yes. You can run up to 26 copy variants per step and let real reply data pick the line that performs best.
Do I need a separate tool for warmup and deliverability?
No. Email warmup, inbox rotation and best-practice sending are built into the sequencer, so your campaigns are protected without bolting on another tool.
Can I use HotHawk instead of HubSpot sequences?
Yes. HubSpot sequences are built for one-to-one follow-ups tied to your CRM, not cold outreach at volume. HotHawk is a dedicated cold email sequencer with multi-step campaigns, inbox rotation, warmup and a master inbox, so it handles high-volume sending HubSpot was never designed for.
