Google AND Microsoft 365
Zapmail is Google-only. Inboxlogy provisions both ecosystems on dedicated US and EU IPs — so you can diversify providers or reach the Outlook-heavy half of B2B without a second vendor.
Comparison
Inboxlogy vs Zapmail
Zapmail is a legitimate, competitively-priced provider of Google Workspace mailboxes for cold email — clean UI, US & EU IPs, and bundled test credits. Inboxlogy covers the same job and adds what Zapmail doesn't: Microsoft 365 alongside Google — warmup runs free in your connected sending tool with no credit meters — no forced packages (order a single mailbox if that's all you need), a full API, explicit 100% ownership, and a best-price guarantee. Here's the honest head-to-head.

In one line
Zapmail is a solid choice if you only need Google mailboxes and its 10 / 30 / 100-mailbox bundles fit your volume. Inboxlogy is the pick when you want Google AND Microsoft 365, with warmup running free in your connected sending tool instead of on bundled credits that can run out — no minimum order (a single mailbox is fine), a full API, and explicit 100% ownership — from $2.80/mo, backed by a best-price guarantee.

A fair comparison names the competitor's strengths first. Here's ours.
Where Zapmail is a good fit
Zapmail is competitively priced, has a clean and easy UI, and bundles warmup, placement-test and AI-insight credits into every plan. If you're Google-only and your volume fits neatly inside a 10-, 30- or 100-mailbox bundle and its credit allowance, Zapmail is a reasonable choice.
Where Inboxlogy wins
Edge 02
No warmup credits to run out

Yes — for most teams setting up cold-email infrastructure, Inboxlogy is the better overall choice: the most competitive per-mailbox pricing ($2.80–$3.50/mo with dedicated US and EU IPs included), no forced packages (buy a single mailbox — Zapmail's plans start at a 10-mailbox bundle), a full API to automate your workflow, and genuine Google Workspace AND Microsoft 365 mailboxes with 100% ownership that connect free to any sending tool, where warmup runs at no extra cost — all backed by a best-price guarantee.
