Paced like a person. Threaded like a conversation.
Build email and call steps once. PEMAX sends each email from the rep's own Google Workspace mailbox, minutes apart, inside the prospect's business hours, in one thread, with a one-click way out. When someone answers, the sequence stops for them.
Every email is checked twice: when the person is enrolled, and again at the moment it leaves.

How it works
From a list to a conversation in four moves.
A sequence is a set of steps every enrolled person walks through on their own clock. You write it once; PEMAX decides when each step is allowed to happen.
- 01
Build the steps
Email, a call task, a place on the power-dial list, a wait, a branch, a follow-up task. Waits skip weekends unless you turn that off, and a branch can follow a field or a reply. - 02
Enrol with a check
Enrolling runs the compliance check per person first. Anyone without a recorded lawful basis, in a country you have not allowed, or without a notice text in their language shows up blocked, with the reason. - 03
Send from the owner's mailbox
Each step goes out from a mailbox the prospect's owner may use, their own first, rotated, paced and inside the market's hours. A rep never sends through a colleague's mailbox. - 04
Stop when they answer
Interested, not interested, unsubscribe and wrong person end the sequence for that person. Out of office pauses it until they are back. Queued sends pause, they are never silently cancelled.
The mechanics
The parts that decide whether a sequence lands.
Most cold email fails on timing, threading and trust long before the copy is read. These are the rules PEMAX applies to every send, whoever set up the sequence.
Pacing and rotation
Two to six minutes apart, never a burst.
Each mailbox waits a random two to six minutes between sends, and two people at the same company are never mailed within ten minutes of each other. Slots land inside the market's business hours, in the market's time zone, so a list in Stockholm and a list in Rotterdam each get their own working day.
- 200 prospects over three mailboxes split 67, 67 and 66
- One capacity rule for every mailbox: 40 a day by default, lower while it warms up
- A full mailbox hands the send to another mailbox the rep may use, or waits for the next local day
- A paused mailbox makes the step wait and retry. It never drops it

Threading and the way out
Every follow-up lands in the same thread.
Each email gets its own Message-ID. A follow-up carries In-Reply-To and References and a “Re:” subject, so the prospect's mail client shows one conversation. Replies are matched on those ids first, and a colleague's mail from the same company is never attached to your prospect by accident.

Hi Daan, a short follow-up on my note from Tuesday. Would a 20-minute call next week help to compare how you plan the December peak today?

AI drafts
AI writes the draft. A person sends it.
An AI step drafts the email for each person. By default every AI-drafted step waits in Review for its rep, in every market, until someone approves it. Only the workspace owner can turn that off, and managed markets review either way.
- A rep who sees only their own prospects reviews only their own drafts
- The AI marking stays on the email after a person edits it
- A monthly AI spend cap, visible in Settings
- If a draft fails, the step keeps the text you wrote as its fallback

Peak weeks at Kuipers Transport
Hi Daan, thanks for picking up yesterday. As promised, here is how Vos & Partners plans its December peak in two pages. Worth a look before your planning round?

In detail
Everything a sequence does for you.
Each rep's own mailbox
Reps connect their own Google Workspace mailbox with Google sign-in. A step sends from the prospect owner's mailbox; a rep who only sees their own prospects never borrows the pool.Loud when access is revoked
When Google withdraws a mailbox's access, the mailbox stops, its queued sends pause and the rep sees “Reconnect your mailbox” with the count waiting. Reconnecting resumes exactly those sends.Calls in the same sequence
A call task with a deadline, or a place on the power-dial list. A sequence with only call steps sends no electronic message, so the email rules do not hold it back.Follow-up tasks
New task from the task list or the prospect drawer, due in the market's own time. Admins assign tasks to a teammate; the list shows Done and Skip.The privacy notice, in their language
The first email to a person carries the GDPR article 14 notice in their language, filled with your data source and privacy page. A missing value blocks the send and says which one.Checked again at the send
The compliance check runs at enrolment and again when the email leaves. Remove a person's lawful basis after enrolling and their queued email fails with the reason, never silently.No double sequences
An address that another sequence mailed in the last 30 days is not mailed by a second one. Manual one-off emails from the inbox are your call and never cancelled.Market time, not server time
Business hours, waits and due dates follow each market's time zone, so a DACH list and a Nordic list each send in their own working day.Hard bounce, hard stop
A hard bounce suppresses the address that failed and stops its sends. A soft bounce makes that person's queued emails wait 24 hours. Nothing is suppressed on a guess.
One honest limit
Sequences send from Google Workspace mailboxes. A Microsoft 365 mailbox can be connected and used to reply from the inbox, but it does not run cold sequences: PEMAX does not read replies, bounces or unsubscribes from an Outlook mailbox, and a sequence that cannot hear “stop” should not send.The details that matter
Pacing, capacity and replies, in numbers.
These are the defaults every new workspace starts with. Each one is a workspace or market setting, so a team with its own rhythm can tune it.
| Rule | Default and effect |
|---|---|
| Gap between sends, per mailbox | 120 to 360 seconds, randomA batch spreads over the morning instead of leaving in one burst. |
| Same recipient domain | 600 seconds apartTwo people at one company never get your mail in the same ten minutes. |
| Sending window | The market's business hours; Mon to Fri, 08:00 to 18:00 when none are setJudged in the market's own time zone. A slot outside the window moves to the next opening. |
| Daily cap per mailbox | 40, or the warmup cap when that is lowerCounted per market-local day. A mailbox that is not warming yet starts at 5. |
| A mailbox is full | Another mailbox the rep may use, else the next local dayCapacity ranks mailboxes. It never drops a send. |
| Soft bounces above 15% in 48 hours | Today's cap halves, re-checked hourlyOld bounces age out of the window, so the cap comes back on its own. |
| A mailbox is paused or reconnecting | The step waits and retries every hourA run is never parked for a temporary problem, and no step is lost. |
| Reply label | What happens |
|---|---|
| Interested | Sequence ends with its goal reached. The lead goes to your CRM when you connected one. |
| Not interested | Sequence ends for this person. |
| Unsubscribe | Sequence ends and the address goes on the suppression list. |
| Wrong person | Sequence ends for this person. |
| Out of office | Sequence pauses until the return date in the reply, or 30 days when there is none. |
| Automatic reply | Nothing changes. Machine noise never stops a sequence. |
| Anything else | Sequence pauses until a person has looked at it. |
A label the classifier is not sure about pauses the sequence instead of ending it. Correct a label in the inbox and every count follows.
FAQ
Questions about sequences
Which mailboxes can send a sequence?
Google Workspace mailboxes, each connected by its own rep with Google sign-in. Microsoft 365 mailboxes can be connected for replies from the inbox, but not for cold sequences, because PEMAX does not read replies or bounces from them. Free addresses such as gmail.com cannot be a sending domain: you need a domain you control, so its SPF, DKIM and DMARC records can be checked.
How many emails does one mailbox send a day?
Forty by default, or less while the mailbox warms up; a mailbox that is not warming yet starts at five. Within that cap the pacing keeps sends minutes apart, so a full day of mail from one rep looks like one person working through a list. Admins can change the daily limit per mailbox.
Can AI write the emails?
Yes. An AI step drafts each email for the person it goes to, and by default the draft waits in Review until its rep approves it. Every AI-drafted email carries an X-AI-Generated header, also after a person edited it. Drafts run on an Anthropic key: your own, sealed in the vault and used only for your workspace, or, where agreed, the platform key under a monthly cap. Drafting inside the browser with your own key is coming soon; sequence steps already use it.
What happens when a rep leaves or loses access?
When Google revokes a mailbox, it stops sending, its queued emails pause and the rep is asked to reconnect. Those emails are not moved to a colleague's mailbox. When someone leaves the team, an admin removes them and hands their prospects and work to a named teammate in one step.
Can a sequence include LinkedIn?
LinkedIn connection requests and messages exist as step types, sent through a LinkedIn account connected with Unipile's hosted sign-in, so PEMAX never sees the password. A LinkedIn message always needs a lawful basis. A connection request without a note is treated as pitch-free, and every such request is logged on the audit trail. Email and phone are where PEMAX does most of its work.
What does PEMAX not do?
It does not send from a domain that fails its DNS check, it does not mail anyone without a recorded lawful basis, and it does not burst a list out in one go. It is also not a CRM: a qualified lead goes to yours through a signed webhook.
