Inbox rotation
Email inbox rotation that spreads volume and keeps every lead in one thread
Connect as many mailboxes as your plan allows, across your main domain and secondary domains. One campaign rotates new leads across them by remaining daily budget and the weights you set, skips mailboxes that are down or off-hours, and keeps each prospect on the mailbox that first wrote to them.

Overview
Why cold email needs inbox rotation
A single mailbox can only send a few dozen cold emails a day before deliverability starts to suffer. Push harder and you risk the whole domain. The standard answer is to spread volume across several mailboxes, often on secondary domains, so each one sends a sustainable amount.
Doing that by hand means splitting lists, duplicating campaigns per mailbox and keeping track of who emailed whom. ReachPods does it inside one campaign: choose which mailboxes it may use, and the rotation engine decides, lead by lead, which mailbox sends the first email.
Rotation runs on the same safety engine as every action. Each mailbox has its own daily limit, warm-up, working hours, timezone and random pacing, and a mailbox that’s busy, outside its hours, out of budget or disconnected is simply skipped for now.
How it picks
Inbox rotation by remaining budget, working hours and weight
When a new lead needs its first email, the rotation skips mailboxes outside their working hours, then runs a weighted round-robin across mailboxes with budget left today. Give your warmest mailbox weight 2 and a fresh one weight 1, and the warm one sends twice the volume.
If a mailbox is pacing between sends, the lead books a slot in its queue instead of every lead hammering the same mailbox at once. Mailboxes in warm-up only offer their ramped-up budget.
- Working hours per mailbox
- Weighted round-robin
- Remaining daily budget first
- Warm-up budgets respected
How it picks
Next email goes to…
- [email protected] · weight 126/40
Remaining budget × weight, inside working hours
Sticky threads
One mailbox per lead, so every follow-up lands in the same thread
Once a lead has a mailbox, every later email step uses it. The first email and each follow-up come from the same person, as replies in the same thread, so the prospect sees one conversation.
Sticky senders work per channel: the same lead can have one mailbox for email and one LinkedIn account for LinkedIn steps, both kept for the whole campaign.
- Same mailbox for every email step
- Follow-ups as replies in one thread

Mailbox recovery
Disconnected mailboxes don’t lose leads
When a mailbox needs reconnecting, its leads are parked, not failed. Reconnect through the hosted sign-in and they resume gradually. Limits, warm-up progress, schedule and timezone are kept.
If a mailbox stays down past the 72-hour grace period, is deleted or removed from the campaign, its leads are reassigned to a healthy mailbox and a fresh thread starts cleanly.
- Leads parked, never failed
- Gradual wake-up after reconnect
- Reassignment after 72 hours
- Fresh thread on the new mailbox

Per-mailbox limits
Daily limits, pacing and timezones for every mailbox in the pool
Each mailbox defaults to 50 emails a day with a random 60 to 240 seconds between sends, only inside its working hours. Budgets reset at each mailbox’s local midnight, so a mailbox in New York and one in Berlin each get a full local day.
Campaigns also have a cap on new leads per day, so a fresh list of 2,000 leads doesn’t all start on day one.
- 50 emails / day by default
- 60–240 s random gaps
- Local-midnight resets
- Daily new-lead cap per campaign

FAQ
Email inbox rotation: questions and answers
Something else on your mind? Get started and try it on your own accounts.
What is inbox rotation?
Inbox rotation spreads a campaign’s emails across several sending mailboxes so each one sends a safe daily volume, instead of one mailbox sending everything.
How many mailboxes can I rotate?
As many as you connect. On Social + Email each mailbox is $39 a month; Cold Email plans include unlimited email accounts. See pricing.
Will follow-ups come from a different mailbox?
No. Each lead sticks to the mailbox that sent the first email, and follow-ups are replies in the same thread.
What if one mailbox gets disconnected?
Its leads are parked and resume when you reconnect. If it stays down for 72 hours, they’re reassigned to a healthy mailbox with a fresh thread.
Can I give some mailboxes more volume?
Yes. Each mailbox in a campaign has a weight; higher weights receive proportionally more new leads.
