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.

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][2][3][4]
- Support blames the email copy instead of fixing the infrastructure, and in two cases working with the team resolved nothing[1][2][3]
- One buyer's mailboxes never worked: they failed to connect to Instantly and failed Microsoft's connectivity test, ending in a refund request[1]
- 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][2][3]
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.

Users complain about
- Mailforge mailboxes were banned from Instantly and Smartlead warmup pools, which made one user stop using it[1][2][3]
- 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][2][3][4]
- 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][2][3]
- Some users dismiss the whole Forge product family as subpar[1][2][3]
