## #7 Maildoso

Maildoso sells SMTP mailboxes for cold outbound email, with automated domain and DNS setup, IP rotation and mailbox health monitoring. Website: maildoso.com. Category: [Email Infrastructure & Verification](https://gtmranked.com/best/email-deliverability/). Score 3/100 (1 positive, 1 mixed, 9 negative of 11 independent comments).

**Verdict:** Independent opinion of Maildoso is overwhelmingly negative, and nearly all of its praise looks promotional. About half of the 100 comments read as marketing: a March 2026 burst of near-identical 'been using it four or five months' reviews repeating the same $1.80 per mailbox, automated DNS and one-click Instantly points, a review thread another commenter called fake, a June 2026 run of casual one-line endorsements, and plugs for rival providers. The roughly ten first-hand opinions report mail landing in spam or drawing no replies after weeks of warmup, mailboxes that would not connect, and support that blames the copy; only a couple of users found it workable.

**What users like:**
- Workable as a hands-off option for some: one user calls it fine at about $1.50 to $2 per mailbox if you don't want to manage DNS yourself, and another says it ran well for their first campaigns before they switched providers [1](https://www.reddit.com/r/coldemail/comments/1ttmb02/_/op59sxh/) [2](https://www.reddit.com/r/coldemail/comments/1rj1297/_/ohokgtc/)

**What users complain about:**
- Mail lands in spam or draws nothing: users report inboxes burning within a week, domains that stopped firing, and a month of warmed sending with best-practice copy that got zero replies while the primary domain booked meetings; one deliverability-minded commenter blames the shared IPs [1](https://www.reddit.com/r/coldemail/comments/1txgvp5/_/opytffe/) [2](https://www.reddit.com/r/Coldemailing/comments/1v4bivw/_/ozoe09w/) [3](https://www.reddit.com/r/coldemail/comments/1qdg1sa/_/o8d3b63/) [4](https://www.reddit.com/r/b2bemailing/comments/1v4bi6k/_/oza716n/)
- Support blames the email copy instead of fixing the infrastructure, and in two cases working with the team resolved nothing [1](https://www.reddit.com/r/b2bemailing/comments/1v4bi6k/_/ozbvnig/) [2](https://www.reddit.com/r/coldemail/comments/1qdg1sa/_/o8d3b63/) [3](https://www.reddit.com/r/coldemail/comments/1igz6vq/_/maswqh3/)
- One buyer's mailboxes never worked: they failed to connect to Instantly and failed Microsoft's connectivity test, ending in a refund request [1](https://www.reddit.com/r/coldemail/comments/1igz6vq/_/maswqh3/)
- Reputation concerns around its own network: users describe low-quality inboxes, a reported blacklisting of the network in mid-2025, and a shift to reselling Google Workspace after its own infrastructure faltered [1](https://www.reddit.com/r/coldemail/comments/1mkqga1/_/n7lbwtp/) [2](https://www.reddit.com/r/coldemail/comments/1l6thok/_/mws5ix9/) [3](https://www.reddit.com/r/coldemail/comments/1rj1297/_/o8dj6d9/)

**Best for:** Testing a small batch of cheap SMTP mailboxes alongside other providers, with close placement monitoring.
**Skip it if:** Agencies whose client results depend on inbox placement; Teams that expect the vendor to troubleshoot spam placement; Anyone relying on a single inbox provider.
**Pricing (vendor-stated, checked 2026-10-14):** Monthly per-mailbox plans: 30 mailboxes for $75/mo ($2.50 each), 300 for $225/mo, 1,000 for $499/mo; domains extra at $15/year; quarterly plans with domains included are labelled legacy. 30-day money-back guarantee on monthly packages; no free plan or trial.

## #2 Zapmail

Zapmail sells Google Workspace and Microsoft 365 mailboxes for outreach, automating mailbox creation and DNS setup and connecting them to sending tools. Website: zapmail.ai. Category: [Email Infrastructure & Verification](https://gtmranked.com/best/email-deliverability/). Score 30/100 (8 positive, 5 mixed, 8 negative of 21 independent comments).

**Verdict:** About 20 independent users give an opinion and they split: the positives are easy setup, fast provisioning and a low price, and its Google and Outlook inboxes are described as working about as well as other resellers. The recurring complaints are slow support once deliverability slips, which several users cite as their reason for moving to another provider, and worse spam placement than Google Workspace bought directly. More than a third of the 100 comments are promotional, including a 2026 cluster of near-identical posts praising its automated DNS provisioning alongside ReachInbox, and plugs for competing inbox providers and tools.

- Unlike Instantly's done-for-you inboxes, you keep control of the Google admin panel [1](https://www.reddit.com/r/coldemail/comments/1qc4t1j/_/nzi0mta/)

**What users complain about:**
- Support is slow or hit and miss, especially once mailboxes start landing in spam; several users moved to PuzzleInbox for better support [1](https://www.reddit.com/r/coldemail/comments/1twkn2z/_/oppks3q/) [2](https://www.reddit.com/r/coldemail/comments/1t9f6bt/_/opzwucy/) [3](https://www.reddit.com/r/coldemail/comments/1sazs8w/_/oquebip/) [4](https://www.reddit.com/r/coldemail/comments/1p7ofmx/_/oqmizk9/) [5](https://www.reddit.com/r/coldemail/comments/1lkw0zd/_/mzwpzm2/)

- Some distrust it as an India-based reseller, citing worse IPs than US providers, and one user alleges deceptive marketing and mailbox disconnects [1](https://www.reddit.com/r/coldemail/comments/1sazs8w/_/odzr1jv/) [2](https://www.reddit.com/r/coldemail/comments/1mtlhet/_/n9d2gzm/)
- Its prewarmed inboxes are criticised as easy for mailbox providers to spot or already tainted by earlier use [1](https://www.reddit.com/r/coldemail/comments/1pfqrs9/_/nsvpqrm/) [2](https://www.reddit.com/r/coldemail/comments/1td6i64/_/olt6dh5/)
