Best for done-for-you Google and Microsoft inboxes
Premium Inboxes sets up Google and Microsoft inboxes for cold email and uploads them to your sequencer. Orders start at 30 inboxes, you bring your own domains, and it sends nothing itself.
Who Premium Inboxes is for
- Fits if you want 30 or more inboxes set up and handed over
- Works for agencies that already have a sequencer
Who Premium Inboxes is not for
- Tight if you need fewer than 30 inboxes, because both plans have a 30-inbox minimum
- Skip it if you want a trial, as there is none
- Watch out: domains are not in the price, so you buy them yourself
- Pricey if you want an account manager, a Slack channel or 24-hour monitoring, since all three need the $4.50 tier
Why Premium Inboxes gets a 1.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

Keep Premium Inboxes, or make your own?
Keep it
To replace Premium Inboxes you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 64 of the 81 other cold outreach tools grade higher. It costs $42 a year.
What you could not
- A network of real inboxes that open and answer your emails.
- Reading the reports inbox providers send about your domain.
- It plugs into other products, Instantly, Smartlead and Apollo among them.
What this rests on. Premium Inboxes’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Premium Inboxes?
Premium Inboxes sets up Google Workspace and Microsoft 365 mailboxes for cold email senders. It configures domains, DNS records, inbox creation, sequencer upload and warmup, and charges a flat price per inbox. The customer brings the domains.
Worth knowing
- You supply the domains; the site does not list domain purchase in the price.
- Both plans start with a minimum order of 30 inboxes.
- It provides mailboxes only; you need a separate sequencer to send campaigns.
- Account manager, Slack channel and 24-hour monitoring come only with the $4.50 tier.
Key features
- Google Workspace and Microsoft 365
- Inboxes are business accounts on either provider, and the pricing page has a toggle for each.
- Technical setup handled
- The vendor says it configures DNS with SPF, DKIM and DMARC, creates the inboxes, sets up profiles and enables warmup.
- Sequencer upload
- Inboxes are uploaded directly to the sequencer. The site lists Instantly, Smartlead, Apollo, Lemlist, Reply.io and Bison.
- Unlimited replacement inboxes
- Both plans include replacement inboxes when one is lost or flagged, with a priority queue on the higher plan.
- Slack support channel
- The higher plan adds a dedicated Slack channel and account manager, and the site says the founder joins customer channels.
- Infrastructure calculator
- A calculator turns a daily send volume into a number of inboxes, domains and a monthly cost.
