As many mailboxes as you need. No seat fees.
Connect every mailbox you own, free, and Inboxed spreads a campaign’s sending across them: each lead stays with one mailbox, each mailbox stays under its daily limit, and sends are spaced like a person would send them.

What it does
No mailbox limit
There’s no per-mailbox or per-seat fee. You pay only for emails that send.
Any provider
Sign in with Google or Microsoft, or use SMTP and IMAP for anything else. Bulk-connect up to 200 mailboxes from a CSV.
Rotation
New leads go to the least-used mailbox that can send right now.
Sticky follow-ups
A lead keeps the mailbox that sent their first email, so follow-ups stay in one thread from one person.
Daily limits and gaps
A daily limit per mailbox (1 to 500) and a random 60–180 second gap between its sends by default.
Provider matching
Optionally prefer a mailbox on the recipient’s mail host (Google or Microsoft), found from their MX records.
Tags
Tag mailboxes (“us”, “client-a”) and send a campaign from every mailbox with a tag.
Automatic pause
A mailbox is paused when more than 5% of its sends hard-bounce (after at least 20 sends).
How it works in Inboxed
Connect
Sign in or enter SMTP/IMAP details. Warmup starts and DNS is checked daily.
Set limits
Daily limit, signature and tags per mailbox.
Pick a pool
A campaign sends from chosen mailboxes and/or every mailbox with chosen tags.
Inboxed rotates
Each send picks a mailbox that is under its cap and past its gap.
Honest limits
What this doesn’t do, and what it needs from you.
- More mailboxes spread volume; they don’t fix a bad list or a blocklisted domain.
- Mailboxes themselves come from your provider (or from Inboxed’s mailbox store, paid monthly). Connecting is free; the mailbox subscription isn’t ours to waive.
Questions
Is there really no limit?
There’s no mailbox limit and no per-mailbox fee in Inboxed. Warmup is free for each one too.
Will follow-ups come from a different address?
No. A lead keeps the mailbox that sent their first email. If that mailbox leaves the campaign, the lead is reassigned like a new one.
What does provider matching do?
When it’s on and a mailbox on the same host as the recipient (Google to Google, Microsoft to Microsoft) can send now, it’s used first. It never goes over a mailbox’s daily limit.
