Comparison
Maildoso's headline price is genuinely the lowest in the market — bulk SMTP inboxes from ≈$0.49/mo, with IP rotation, an API + MCP and a 30-day money-back guarantee. Two things to check before you buy: the cheap tiers are shared SMTP inboxes on Maildoso's own infrastructure, not genuine Google or Microsoft accounts, and they have no warmup — while Inboxlogy's genuine mailboxes warm up free in the sequencer you already use. Here's the honest head-to-head — account types, warmup, the real all-in math, and ownership.
Last updated July 2026
In one line
Maildoso is the cheapest sticker price in cold email — from ≈$0.49/inbox, and that number is real. But the cheap tiers are shared SMTP inboxes, not genuine Google or Microsoft accounts, and they have no warmup — a separate warmup tool runs ≈$15–25/inbox/mo, pushing the real all-in cost to ≈$17–27+ per inbox. Inboxlogy's $2.80–$3.50 genuine Workspace & 365 mailboxes — dedicated US and EU IPs included — warm up free in the sequencer you already use, so they usually cost less for real inbox placement.

Maildoso wins the sticker-price line — honestly and clearly. The separation happens on account type, warmup and ownership. Where Maildoso doesn't publish a spec, we say so instead of guessing.

03 / The all-in math
Maildoso's headline price is real — we won't pretend otherwise. But cold email without warmup isn't a real setup, and Maildoso's shared SMTP inboxes don't come with one. Inboxlogy's genuine mailboxes warm up free inside the sequencer you already run; Maildoso's need a separate tool — and that changes the math.

Example at 30 inboxes: Maildoso $75/mo SMTP + ≈$450–$750/mo in warmup tooling ≈ $525–$825/mo · Inboxlogy ≈ $78–$105/mo ($2.80–$3.50 × 30), with warmup running free in your sequencer. Compared Jul 2026 — verify before buying.
04 / Fair look
Where Maildoso is a good fit
Credit where due: Maildoso's sticker price is the lowest in the market and it isn't a trick — bulk shared-SMTP inboxes really do start around $0.49/mo. It ships IP rotation, an API plus an MCP integration, free deliverability audits and a 30-day money-back guarantee, and domains are free on quarterly plans. If you want maximum raw sending capacity at minimum cost, already run your own warmup stack, and are comfortable operating on shared SMTP infrastructure rather than genuine Google or Microsoft accounts, Maildoso's pricing is genuinely hard to beat on paper.
Every Inboxlogy mailbox is a real Google Workspace or Microsoft 365 account — the infrastructure receiving servers trust most. Maildoso's cheap tiers are shared SMTP inboxes on its own platform; genuine Google costs ≈$3 on combo plans, and Microsoft isn't listed.
Your sending tool — Instantly, Smartlead, ReachInbox — already includes warmup, and Inboxlogy's genuine mailboxes connect to it free over OAuth, app password or IMAP, plus API. No separate warmup fee, ever. Maildoso's shared SMTP inboxes ship with no warmup, and a dedicated warmup tool typically runs ≈$15–25/inbox/mo — turning $0.49 into ≈$17–27 all-in.
Full admin access and 100% ownership of every workspace and domain, explicitly. Leave anytime and move billing directly to Google or Microsoft. Shared SMTP inboxes live on the provider's platform — there's nothing to transfer if you go.
Inboxlogy sends from dedicated US and EU IPs with automated SPF, DKIM and DMARC on every mailbox. Maildoso rotates IPs across shared infrastructure — a legitimate technique, but your reputation rides with everyone else on the pool.
05 / The verdict
For anyone setting up cold-email infrastructure, Inboxlogy is the best overall choice: the most competitive per-mailbox pricing, no forced packages (buy a single mailbox, not a bulk pack), a full API to automate your workflow, and genuine Google & Microsoft mailboxes (dedicated US and EU IPs) and 100% ownership included that connect free to any sending tool — all backed by a best-price guarantee.

Worth spelling out on this page: Maildoso's ≈$0.49 shared-SMTP inboxes don't trigger the match — not because we're dodging, but because they're a different product. A shared SMTP inbox with no warmup path isn't comparable to a genuine Google Workspace or Microsoft 365 mailbox on dedicated US and EU IPs with full ownership and free connection to the tool where your warmup runs. Bring us a like-for-like quote and we'll match it.
*Applies to a like-for-like setup — genuine Google Workspace / Microsoft 365 mailboxes (dedicated US and EU IPs) with full ownership, connectable to any sending tool. Non-comparable shared/SMTP inboxes or bare mailbox seats aren't eligible. Prices verified Jul 2026.
06 / FAQ
The questions outbound teams actually ask when comparing the two — with July 2026 numbers.
For real inbox placement, yes. Inboxlogy provides genuine Google Workspace and Microsoft 365 mailboxes (dedicated US and EU IPs) at $2.80–$3.50 per mailbox/mo with 100% ownership, no minimum purchase, a full API and a best-price guarantee — and every mailbox connects free to any sending tool (Instantly, Smartlead, ReachInbox), where warmup runs at no extra cost. Maildoso's headline price is genuinely lower (from ≈$0.49/inbox), but its cheap tiers are shared SMTP inboxes on Maildoso's own infrastructure — not genuine Google or Microsoft accounts — and they have no warmup, so a separate warmup tool (typically ≈$15–25/inbox/mo) is needed for cold outreach. All-in, Inboxlogy usually costs less for a comparable, deliverability-ready setup. Figures as of July 2026 — verify before buying.
On sticker price, yes — Maildoso's bulk SMTP inboxes start at ≈$0.49/mo and its monthly SMTP plans run ≈$1.90–$2.50 per inbox, genuinely the lowest headline price in the market. But those shared SMTP inboxes have no warmup, and a separate warmup tool typically costs ≈$15–25 per inbox per month — pushing the real all-in cost to ≈$17–27+ per inbox. Inboxlogy's $2.80–$3.50 buys a genuine Google Workspace or Microsoft 365 mailbox with dedicated US and EU IPs included, and warmup runs free inside the sequencer you already use — Instantly, Smartlead and ReachInbox all include it, and Inboxlogy connects to them free. No separate warmup line ever gets added, so for real inbox placement Inboxlogy is usually the cheaper option all-in. As of July 2026 — verify current pricing.
The cheap tiers are not — they are shared SMTP inboxes running on Maildoso's own infrastructure. Maildoso does offer genuine Google mailboxes on its combo plans at ≈$3 per mailbox ($90 for 15 SMTP + 15 Google, as of July 2026); no Microsoft 365 option is listed. Every Inboxlogy mailbox is a genuine Google Workspace or Microsoft 365 account with full admin access and 100% ownership.
With Inboxlogy, yes — there are no forced packages and no minimums. Buy exactly one mailbox or a thousand; your per-mailbox rate simply follows your volume tier ($3.50 down to $2.80). Maildoso's lowest rates come from bulk SMTP packs (30, 70 or 300 inboxes), so its cheapest headline prices require buying in volume.
Yes. Inboxlogy has a full API — you can order, provision and manage mailboxes programmatically and automate your entire cold-email workflow end-to-end. Credit where due: Maildoso also ships an API plus an MCP integration, so both providers score well on automation. The difference is what the API provisions — Inboxlogy's API creates genuine Google Workspace and Microsoft 365 accounts you own.
Yes. Find a lower price on comparable cold-email infrastructure, show us the quote, and we'll match it — and still include dedicated US and EU IPs, 100% ownership and free connection to any sending tool. The asterisk: it applies to like-for-like setups — genuine Google Workspace or Microsoft 365 mailboxes (dedicated US and EU IPs) with full ownership, connectable to any sending tool. Non-comparable shared/SMTP inboxes or bare mailbox seats aren't eligible — which is why Maildoso's ≈$0.49 shared-SMTP tier doesn't trigger the match: it's a different product. Prices verified July 2026.
