OD Olga D. product Small-Business (50 or fewer emp.) 7/27/2026 "Issue with domains" 1/5 What do you like best about maildoso? To their credit, once I escalated the issue Maildoso acted fairly on the money side: they cancelled all subscriptions and issued a full refund of everything I had paid. So on billing, the matter was ultimately resolved correctly, and I want to acknowledge that. Review collected by and hosted on G2.com. What do you dislike about maildoso? The core problem is the product itself. Every domain I received was already on the SURBL ABUSE blacklist — I checked 6 of 6, including one that had never sent a single email, which means it was blacklisted before I ever used it. The result: mail-tester scored 8.2/10 with a URIBL\_ABUSE\_SURBL penalty and my emails went straight to spam — regardless of warmup or domain age. The identical email sent from my own clean domain scored 10/10 and landed in the inbox. The product is marketed for cold outreach, yet these domains were unusable for exactly that purpose. Support was also very slow: replies took more than 24 hours, and there was no response at all on weekends — which makes a time-sensitive deliverability problem hard to resolve. Getting a refund fixes the money, but it does not change the fact that the domains couldn't reach the inbox. I'd encourage anyone considering Maildoso to check the SURBL/blacklist status of the domains before sending. In principle Maildoso should provide ready-to-use infrastructure for cold email. In my case it did not solve that problem — the domains couldn't reach the inbox, so the core value (deliverability) wasn't there, and support responses were slow (24h+, none on weekends). On the positive side, the refund was handled in full after I raised the issue. Review collected by and hosted on G2.com.

CEO/Founder Small-Business (50 or fewer emp.) 8/10/2026 "Maildoso Delivers Some of My Best Campaign Results" 4.5/5 What do you like best about maildoso? Maildoso solves a real problem. One of the best campaign results I’ve gotten came from using Maildoso’s accounts. Review collected by and hosted on G2.com. What do you dislike about maildoso? So far, I haven’t run into any problems. The only thing I’d mention is that I used to be a GW user, and in my email accounts I had a profile picture and everything, which instantly gave a more human-like vibe. I’m not sure if that really matters, but it might add a small trust factor. Either way, I don’t really care. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? Deliverability and volume, both at the same time. Maildoso’s drop in price has really helped a small agency like mine keep campaigns running consistently without spending too much. We’re able to 5x our volume while paying about 1x the price of Google Workspace accounts. Review collected by and hosted on G2.com.

CEO & President Airlines/Aviation Mid-Market (51-1000 emp.) 5/27/2026 "Stable Infrastructure and Higher Reply Rates with Maildoso" 5/5 What do you like best about maildoso? We switched from Inboxkit to Maildoso after another agency recommended it to us. During the first month, after warmup, our reply rates were around 1.5x-2x higher than what we were normally seeing before. What surprised me most is the stability after that initial period. At one point some mailboxes burned, so we paused campaigns for about 2 weeks. After restarting, performance actually improved instead of getting worse. Since then, the infrastructure has been running very consistently for us without needing constant maintenance or rebuilding inboxes every other week. Review collected by and hosted on G2.com. What do you dislike about maildoso? The beginning was a little stressful because a few mailboxes burned during the first month, and we weren’t sure if we would have to repeat the whole setup process again. The dashboard could also be a bit clearer in some sections. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? Before this, managing outreach infrastructure felt like a nonstop cycle of creating inboxes, warming them up, replacing them, and setting everything up again. Maildoso reduced a lot of that manual maintenance for our team. At this point, we barely even check the dashboard anymore because things have been running pretty steadily for the last couple months.

I have been using it for a year already. Out of all SMTP providers, this one is the best. First of all, I want to say – SMTP often shows higher results than GW or MS 365. The claim that SMTP allegedly works worse is tales told by sequencers, as it is important for them to attract clients with GW/MS mailboxes. In reality, spam filters do not care about SMTP – millions of emails (service, transactional, opt-in) are sent from SMTP, and nothing lands in spam. Review collected by and hosted on G2.com. What do you dislike about maildoso? I liked everything. There are no complaints. The only thing that can be fixed is onboarding. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? Maiildoso is the best provider in the SMTP niche. And there is nothing scary about using SMTP, they work not a bit worse.

Owner Information Technology and Services Small-Business (50 or fewer emp.) 7/20/2026 "Stable infrastructure designed for high-volume email operations" 5/5 What do you like best about maildoso? Their robust API makes bulk domain acquisition and provisioning incredibly easy to automate. The automatic SSL certificate generation functions flawlessly, meaning our domains are immediately primed for warmup in our outbound sequencing tools. Review collected by and hosted on G2.com. What do you dislike about maildoso? Maildoso charges a flat rate of $12 for any domain name, regardless of the TLD. This can be annoying because cheaper extensions like .xyz or .info cost much less on standard registrars, so you end up paying a premium for the automated setup convenience. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? We struggled with the tedious nature of manually preparing secondary sender domains. We used to lose up to 20% of our newly purchased inboxes due to minor DNS misconfigurations, but Maildoso has completely eliminated those setup errors Review collected by and hosted on G2.com.

Chief Executive Officer Consulting Small-Business (50 or fewer emp.) 7/17/2026 "Reliable, Cost-Effective SMTP/IMAP Inboxes with Excellent Deliverability" 5/5 What do you like best about maildoso? This platform offers an exceptionally reliable and cost-effective alternative to expensive workspace providers. We route our cold campaigns through their proprietary SMTP/IMAP inboxes. At just $0.75 per email account, our infrastructure costs are three times lower than with our previous provider, while retaining excellent deliverability. Review collected by and hosted on G2.com. What do you dislike about maildoso? Customer support response times can be sluggish, particularly when submitting tickets outside of European business hours. For enterprise-level accounts, having a dedicated account manager would be a major improvement. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? We needed to scale our outbound operations to over 150 active senders but faced prohibitive infrastructure costs. Maildoso enabled us to drastically reduce our lead generation budget without sacrificing email deliverability or domain health. Review collected by and hosted on G2.com.

AB Alex B. Product Manager Program Development Mid-Market (51-1000 emp.) 7/26/2026 "Quick Setup, Smooth Integration, and Big Savings on Mailboxes" 5/5 What do you like best about maildoso? Ngl, I was pretty sceptical. Mailboxes for $0.49–$0.75 sounded like one of those deals where you save money upfront and then spend the next month fixing random issues. But honestly, it’s been fine. Setup was quick, the mailboxes connected to our sending tool without drama, and the bill is way lower than it used to be. Idk what else I’m supposed to ask for at this price. Review collected by and hosted on G2.com. What do you dislike about maildoso? The cheapest rate is for higher volumes, so it’s not quite the same deal if you only need a handful of mailboxes. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? Our infra costs stopped eating into the margin on smaller client campaigns.

Sales Executive Real Estate Enterprise (\> 1000 emp.) 6/3/2026 "Scaled Outreach Smoothly While Keeping Multiple Sending Environments Organized" 5/5 What do you like best about maildoso? We run outreach for several clients at the same time, so keeping everything organized is important. What I like most is that we can manage different sending environments without creating extra work for the team. Over the last 4 months, we've scaled from 12 to 38 active mailboxes and the process has been fairly smooth. Review collected by and hosted on G2.com. What do you dislike about maildoso? There are a few sections where I wish there were more explanations for newer users. We figured things out after a while, but some features could be easier to understand on day one. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? The biggest benefit has been reducing operational work. Previously, we spent too much time moving between different providers and checking accounts manually. Now our team can spend more time building campaigns and working with clients instead of managing infrastructure. Review collected by and hosted on G2.com.

Founder Management Consulting Small-Business (50 or fewer emp.) 7/24/2026 "More Positive Replies and Stable Deliverability After Switching to Maildoso" 5/5 What do you like best about maildoso? I manage outbound for a recruitment agency working with US tech companies. Before moving to Maildoso, we received around 20–25 positive replies per month. After the migration, that increased to roughly 45–50. Our reply rate also improved from about 2.7% to 4.6%. We cleaned our contact lists and reduced the daily sending limits at the same time, so Maildoso wasn’t the only reason for the improvement. Still, deliverability became much more stable after the move. Review collected by and hosted on G2.com. What do you dislike about maildoso? Reply analytics aren’t available inside Maildoso, so we still track them in our outreach platform. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? We generated more convos without increasing our sending volume. Review collected by and hosted on G2.com.

We started using Maildoso a few months ago for outbound campaigns and it has made inbox management easier for our team. I like that we can keep multiple sending accounts in one place without spending too much time setting everything up. The onboarding process was simpler than expected and we were able to start campaigns fairly quickly. Review collected by and hosted on G2.com. What do you dislike about maildoso? The dashboard can feel slightly cluttered after adding more inboxes, especially when switching between accounts. Support has been decent overall, but there were a few moments where responses took longer than expected. Review collected by and hosted on G2.com. What problems is maildoso solving and how is that benefiting you? It helps us manage outreach infrastructure without relying on a fully manual process. Before this, keeping track of inboxes and domain settings across different tools was more time consuming. With Maildoso things feel more centralized and easier to maintain week to week.
