## #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.

## #5 Mailforge

Mailforge sells cold-email infrastructure: it registers domains, creates mailboxes on a shared IP pool and sets up DNS (SPF, DKIM, DMARC) automatically. Website: mailforge.ai. Category: [Email Infrastructure & Verification](https://gtmranked.com/best/email-deliverability/). Score 18/100 (5 positive, 2 mixed, 9 negative of 16 independent comments).

**Verdict:** Independent opinion leans negative. The most repeated complaint is that Mailforge mailboxes were banned from Instantly and Smartlead warmup pools, and several users rank shared-IP SMTP mailboxes like these below Google Workspace or Microsoft 365, describing deliverability as average or a case of getting what you pay for. A handful of small users report no deliverability problems and value it as a cheap, quick way to add domains, though how easy setup is remains disputed. More than a third of the 100 comments were promotional, largely accounts repeatedly plugging a particular email finder, list verifier or rival inbox seller next to Mailforge, plus posts from the vendor's side; those were set aside, including several that blame Mailforge's shared IPs for spam placement.

**What users like:**
- A few smaller users report no deliverability problems so far, and one calls the setup easy [1](https://www.reddit.com/r/agency/comments/1g01mb4/_/m0eps74/) [2](https://www.reddit.com/r/coldemail/comments/1in8ygq/_/mceemo8/) [3](https://www.reddit.com/r/coldemail/comments/1inw2fi/_/mcigjb0/)
- Considered a reasonable shared-IP option for scaling: easier and cheaper than Google or Microsoft mailboxes and not exposed to their ban waves [1](https://www.reddit.com/r/coldemail/comments/1msr5xc/_/n9dyl2h/) [2](https://www.reddit.com/r/coldemail/comments/1q29icv/_/nxcmmpg/) [3](https://www.reddit.com/r/coldemail/comments/1sipnmu/_/ofn24r0/)

**What users complain about:**
- Mailforge mailboxes were banned from Instantly and Smartlead warmup pools, which made one user stop using it [1](https://www.reddit.com/r/coldemail/comments/1loe2j4/_/nc8fvcp/) [2](https://www.reddit.com/r/coldemail/comments/1kwxu8s/_/nc8elkr/) [3](https://www.reddit.com/r/coldemail/comments/1dzd9o8/_/m7c6xk1/)
- Shared-IP SMTP deliverability is seen as weaker than Google Workspace or Microsoft 365; one user who ran a campaign found it just average [1](https://www.reddit.com/r/coldemail/comments/1msr5xc/_/oq585a4/) [2](https://www.reddit.com/r/coldemail/comments/1msr5xc/_/n96vl2c/) [3](https://www.reddit.com/r/coldemail/comments/1q29icv/_/nxcmmpg/) [4](https://www.reddit.com/r/coldemail/comments/1fuq4ec/_/lq9byve/)
- Extra fees and setup friction: add-on charges for domain masking, a more manual setup than expected, and one buyer who spent $300 on Mailforge before realising the Google and Microsoft mailboxes they wanted were sold separately under Primeforge [1](https://www.reddit.com/r/coldemail/comments/1msr5xc/_/oq585a4/) [2](https://www.reddit.com/r/coldemail/comments/1kj6gzk/_/o646xc2/) [3](https://www.reddit.com/r/coldemail/comments/1gdxlm8/_/lu5d72u/)
- Some users dismiss the whole Forge product family as subpar [1](https://www.reddit.com/r/coldemail/comments/1fu4imu/_/lpz8b8z/) [2](https://www.reddit.com/r/coldemail/comments/1msr5xc/_/n96f30i/) [3](https://www.reddit.com/r/coldemail/comments/1loe2j4/_/nc8fvcp/)

**Best for:** Senders who want cheap shared-IP mailboxes to add domains quickly; Mixed setups that keep the most important campaigns on Google Workspace or Microsoft 365.
**Skip it if:** Senders who depend on Instantly or Smartlead warmup pools; Teams that need real Google or Microsoft mailboxes; Campaigns aimed at enterprise or Outlook-heavy audiences.
**Pricing (vendor-stated, checked 2026-10-14):** Usage-based: $3 per mailbox slot per month, minimum 10 slots, with 2 months free on annual billing; .com domains $14/year each; optional SSL and domain masking at $2 per domain per month. No free plan or trial; no contract.
