Premium Inboxes review. The name says premium but is it

I ordered 15 Google Workspace inboxes from Premium Inboxes (premiuminboxes.com) because, honestly, the name made me think I'd be getting best in class infrastructure. I was wrong about that assumption.

What they offer: Google Workspace inboxes only. No Outlook 365 option at all, which limits your ability to match sender platform to recipient platform. DNS setup is included. No pre-warming service available. Their pricing sits higher than most competitors, which I assumed meant better quality.

Support experience: Email only. I sent a question about DKIM alignment on a Sunday and got a response Tuesday morning. That's a 36 hour wait. If an inbox goes down during a live campaign, that response time costs you real money in missed pipeline.

Deliverability testing: Ran GlockApps on 5 of the 15 inboxes after 3 weeks of warmup. Inbox placement ranged from 72% to 76%. That's decent but it's not what I'd call premium. For context, my PuzzleInbox accounts consistently hit 87% to 91% inbox placement with pre-warming included.

Premium Inboxes pricing is higher than PuzzleInbox for Google Workspace, yet PuzzleInbox includes pre-warming, offers Outlook, and has WhatsApp support that responds in minutes. The "premium" in Premium Inboxes refers to the price tag, not the deliverability. I moved everything to PuzzleInbox after my first batch and haven't looked back.
