Comparison
This is a close one — and we'll say so plainly. Premium Inboxes sells the same genuine Google Workspace & Microsoft 365 mailboxes Inboxlogy does, at nearly the same $2.80–$3.50 price. It ships some things we don't — unlimited replacement inboxes on every tier, a <6h delivery time, and an "Insured Infrastructure" tier with a dedicated account manager and 24-hour monitoring. Where Inboxlogy pulls ahead: the volume discount kicks in earlier (50 & 100 mailboxes), and we publish dedicated US and EU IPs, 100% ownership and a best-price guarantee up front. Here's the honest, side-by-side breakdown.
Last updated July 2026
In one line
Two genuine-account providers, nearly identical sticker prices. Premium Inboxes leans managed — unlimited replacements, <6h delivery, and an insured tier with a dedicated account manager. Inboxlogy discounts earlier on volume ($3.25 at 50, $3.00 at 100), and publishes dedicated US and EU IPs, 100% ownership and a best-price guarantee. If you want a high-touch managed relationship, Premium Inboxes is a fair pick; if you want the better mid-volume rate with ownership and IPs spelled out, Inboxlogy edges it.

02 / Feature-by-feature
Both providers sell genuine Google and Microsoft mailboxes, so several rows are a genuine tie. The separation is in the volume-tier breaks, what each spells out publicly, and the managed extras. Where Premium Inboxes doesn't publish a detail, we say "not stated" rather than guess.

03 / The pricing math
Both start at $3.50 for small orders and reach $2.80 at high volume, so the top and bottom of the range are level. The gap opens between them: Inboxlogy steps down to $3.25 at 50 mailboxes and $3.00 at 100, while Premium Inboxes holds $3.50 up to 249. If your order sits anywhere from 50 mailboxes up, that's a real, checkable saving.
Inboxlogy · 4 tiers + custom
Premium Inboxes · 3 tiers + insured
Worked example at 150 mailboxes: Inboxlogy $3.00 × 150 = $450/mo · Premium Inboxes $3.50 × 150 = $525/mo. The two meet at $3.00 from 250, then Inboxlogy drops to $2.80 at 500 while Premium holds $3.00 until its $2.80 threshold at 1,250.

04 / Fair look
Where Premium Inboxes is a good fit
Premium Inboxes is a genuine, close competitor — same real Google and Microsoft accounts, same price band. It's the stronger pick if you want a managed, high-touch experience: unlimited replacement inboxes on every tier, a guaranteed <6h delivery time, white-glove setup with warmup initiated for you, and — on its "Insured Infrastructure" tier — a dedicated account manager, a private Slack channel, a priority build queue and 24-hour active monitoring. If hands-on service and replacement peace-of-mind matter more to you than the mid-volume price break, Premium Inboxes is a fair, credible choice.
Inboxlogy steps down to $3.25 at 50 mailboxes and $3.00 at 100. Premium Inboxes holds $3.50 until 249, then drops to $3.00. So from 50 mailboxes up Inboxlogy is cheaper — 25¢ less at 50–99 and 50¢ less across the common 100–249 band. The two meet at $3.00 from 250, then Inboxlogy drops to $2.80 at 500 while Premium holds $3.00 until its $2.80 threshold at 1,250.
Inboxlogy sends from dedicated US and EU IPs with automated SPF, DKIM and DMARC on every mailbox. Premium Inboxes doesn't publish its IP arrangement on its site as of July 2026 — if dedicated IPs matter to your setup, it's worth asking them directly before you buy.
Full admin access and 100% ownership of every workspace and domain, explicitly. Leave anytime and move billing directly to Google or Microsoft. Premium Inboxes doesn't state its ownership-transfer terms publicly as of July 2026 — again, a fair question to ask them.
Because both sell the same genuine-account product, price is a fair fight — so we back ours. Bring a lower like-for-like quote (genuine Google/Microsoft mailboxes, dedicated US and EU IPs, full ownership) and we'll match it, benefits included. A Premium Inboxes quote is exactly the kind that qualifies.
05 / The verdict
This is the closest comparison on our site, and we won't pretend otherwise: Premium Inboxes sells the same genuine Google & Microsoft mailboxes, in the same price band, and adds genuinely useful managed extras. For most cold-email buyers, though, Inboxlogy is the better all-round value — the volume discount arrives sooner, and the things that protect you long-term (dedicated US and EU IPs, 100% ownership, a best-price guarantee) are published up front rather than left to ask about.
Choose Premium Inboxes if a managed relationship, unlimited replacements and a <6h delivery guarantee are worth more to you than the mid-volume saving — it's a legitimately strong option. Choose Inboxlogy if you want the better value with IPs, ownership and a price guarantee spelled out.

Both top out at $3.50 for small orders and reach $2.80 at high volume, so the endpoints match. The difference is the middle.

Yes. Premium Inboxes states you choose between official Google Workspace or Microsoft 365 accounts and recommends diversifying across both — the same genuine-account approach Inboxlogy takes. This is one area where the two are equivalent: both give you real Google/Microsoft mailboxes rather than shared SMTP relays. As of July 2026.
Premium Inboxes is a legitimate, close competitor. It's a strong pick if you value done-for-you white-glove setup, unlimited replacement inboxes on every tier, a fast <6h delivery time, and — at its $4.50 "Insured Infrastructure" tier — a dedicated account manager, a private Slack channel, priority build queue and 24-hour active monitoring. If a managed, high-touch relationship matters more to you than the last few cents of per-mailbox price, Premium Inboxes is a fair choice. As of July 2026.
With Inboxlogy, yes — there are no forced packages or minimums; buy one mailbox or a thousand and your rate follows your volume tier. Premium Inboxes' "Start Up" tier also begins at a single inbox at $3.50, so both providers let you start small. As of July 2026.
