ManyPI sends cold email from your own mailboxes, not from a shared ManyPI domain. That means your deliverability is yours: your domain, your reputation, your replies landing in your inbox.

​
The four pieces

1

Inbox

A mailbox you connect, over Gmail/Outlook OAuth or plain SMTP. It carries the daily cap, the warmup schedule and the health score.
2

Sequence

The email steps: step 1 plus timed follow-ups, with merge variables so one template personalises across every lead.
3

Campaign

Binds one sequence to one inbox, and carries the send window, daily limit, tracking and priority.
4

Enrollment

A lead placed into a campaign. ManyPI schedules the steps, sends them within the caps, and stops the moment they reply.

​
The sending loop

ManyPI’s scheduler runs continuously and decides, for every due enrollment, whether it may send right now:
  1. Is the campaign active and inside its send window (days of week, hours, timezone)?
  2. Has the inbox hit today’s cap? The cap is the warmup-aware number, not the raw daily limit.
  3. Has the campaign hit its own daily limit?
  4. Is the address suppressed, unsubscribed or known-undeliverable?
  5. Has the lead replied? If so, remaining steps are cancelled.
Sends are staggered, not fired in a burst — twenty emails at 09:00:00 looks exactly like what it is.

​
What stops a sequence

​
Plan gates

Sending to leads requires a paid plan. Free workspaces can connect an inbox, build sequences, create campaigns and send test emails to themselves — they just cannot enroll leads or send to them. Hitting a gate over the API returns 403 with code: "outreach_locked".

​
Where to go next

Inboxes & warmup

Connect Gmail, Outlook or SMTP, and ramp a new domain safely.

Sequences

Steps, merge variables, threading, AI drafting and A/B variants.

Campaigns

Send windows, daily limits, enrollment and per-campaign analytics.

Replies & deliverability

Sentiment, bounces, suppressions and unsubscribes.
