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.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $3.50 an inbox a month with a 30-inbox minimum, so $105 a month at the floor. $4.50 on the dearer tier. |
| Free plan and trial | F | No free plan and no trial is listed, so you pay before you try it. |
| Features | D | Inbox setup, replacements and a sequencer upload. It needs a sequencer, and the domains are yours to buy. |
| Ease of use | C | No store rating on record. You hand over domains and connect a sequencer. |
| Platforms and integrations | B | Web dashboard, with uploads to Instantly, Smartlead, Apollo, Lemlist, Reply.io and Bison. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Agencies that want mailboxes built for them rather than DIY
- Teams that want official Google or Microsoft accounts
- Senders who prefer per-inbox pricing with no contract
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.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
