"Effortlessly Manages Cold Email Outreach"
5/5
What do you like best about maildoso?

maildoso makes setup easy. Once everything is connected, I don't have to keep fixing things every time I want to start a new campaign. I appreciate having multiple inboxes ready to use because it helps spread out sending instead of relying on just one account. It makes day-to-day outreach less stressful. Scaling is smoother since I don't have to spend time creating and configuring each inbox individually. It saves time and keeps things organized when running outreach. The initial setup was pretty straightforward, with clear steps that didn’t take much time to figure out. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

Support could be a bit faster sometimes, especially when we’re setting things up or something isn’t clear. It’s not a constant issue, but when you’re trying to launch a campaign it can slow things down a bit. Also the dashboard could feel a little smoother when switching between multiple inboxes, it gets slightly repetitive when you’re managing a lot at once. Review collected by and hosted on G2.com.

"Self-Healing Saves Time and Simplifies Mailbox Management"
5/5
What do you like best about maildoso?

I use Maildoso to manage about 600 mailboxes, and the self-healing feature is definitely the biggest advantage for us. It removes weak mailboxes from sending and gives them time to recover, which has drastically reduced the amount of daily mailbox monitoring our team has to do. This makes it so much easier to manage hundreds of mailboxes efficiently. The setup was straightforward, and we had our mailboxes ready quickly. The platform was easy to start using without needing much manual configuration. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

I can't see which mailboxes are active and which ones are currently recovering. Review collected by and hosted on G2.com.

"Effortlessly Manages Email Campaigns"
5/5
What do you like best about maildoso?

I like using Maildoso for managing cold email campaigns because it simplifies handling a large number of inboxes and dealing with replies without the hassle of manual setup. The automated DNS settings are great since our domains last 2 or 3 times longer, which addresses domains burnout. I have 80 active mailboxes that send about 17-20 emails each, totaling around 30,000 emails a month, and our placement rates are strong, close to 95% on testing. It's also nice that they push updates often, showing that they are actively improving things instead of just leaving it as is. Setting up Maildoso was pretty smooth compared to our previous more manual setup. Overall, I'm extremely likely to recommend Maildoso. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

I had a hiccup with a non US credit card not going through. But we resolved it eventually. Review collected by and hosted on G2.com.

"Effortless Cold Outreach with Reliable Deliverability"
5/5
What do you like best about maildoso?

I find the global customer tracking really helpful because it prevents hitting spam filters even when including links in the first email, which is great for scheduling demo calls early. Our reply rate is around 3-5% in a competitive B2B SaaS niche, and the API integration with Instantly was seamless, connecting mailboxes with just one click. I also appreciate the savings on domain registration, which is just $12 for a .com, and there’s no need to stress over manually writing MX and SPF records. The initial setup was pretty smooth as well. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

There were a couple of delays with activating new workspace accounts. The site said 2 hours but it actually took until the end of the day. Their response rate needs to be improved. Review collected by and hosted on G2.com.

"Effortless Mailbox Scaling with Automated DNS"
5/5
What do you like best about maildoso?

I appreciate Maildoso for solving our clustering issues, where each mailbox is isolated, preventing all accounts from being affected if one gets banned. The transition of moving 120 mailboxes was smooth, with no breakage. What stands out to me is not having to manually set up DNS for every domain, as it's automated, saving a lot of time. This automation allows us to spin up new domains faster. Additionally, the pricing is noticeably cheaper than our previous provider, and the initial setup was straightforward. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

Support can sometimes make you nervous. I messaged the chat on the site and waited about four hours for a reply which was annoying. When something feels urgent, waiting a few hours can be a bit stressful, especially if campaigns are running. Even a quick acknowledgement would help so you know someone is on it.

"Game-Changer for Cold Emailing with High Deliverability"
5/5
What do you like best about maildoso?

I appreciate maildoso for its Global Custom Domain Tracking feature, which is a complete game changer. It allows me to add links like Calendly or Loom to the first email without worrying about landing in the spam folder, providing more confidence when sending campaigns. The IP reputation is very high quality compared to what you get elsewhere, effectively stopping the 'spam folder' trap. The initial setup was pretty well, and overall, I'm extremely likely to recommend maildoso to a friend or colleague. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

I wish there was an audit log to see what my other team members changed. Maybe just more visibility into how the tracking is performing would be nice, like simple stats. Review collected by and hosted on G2.com.

"Effortless Deliverability for Agencies"
5/5
What do you like best about maildoso?

I appreciate that with Maildoso, I no longer need a dedicated technical person to maintain our email servers as everything runs on autopilot. We switched to their combo package (SMTP + GW), and it really helped with deliverability; most emails actually land now, around 90-95% from what we see. It's very convenient to buy domains directly in the dashboard, and the initial setup was straightforward, which made the transition smooth. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

Some of my domains got blacklisted after the first campaign, but they replaced them for me with new ones. I think the main thing would be better prevention or early warnings, like some kind of alert if a domain is at risk before it actually gets blacklisted. Review collected by and hosted on G2.com.

"Reliable Stability and Responsive Support"
5/5
What do you like best about maildoso?

I really appreciate that Maildoso just works. Once everything was set up, I didn’t have to keep fixing things all the time, which is a huge relief. The stability and account management it provides have made our operations a lot more consistent. Moreover, their support has been pretty responsive whenever we needed help with smaller requests like connecting our own domains. Also, the initial setup was pretty easy, which made the transition smooth for us. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

Maybe the dashboard could be a bit cleaner in some sections. Review collected by and hosted on G2.com.

"Scalable Email Solution with Predictable Costs"
5/5
What do you like best about maildoso?

I like using Maildoso for running high-volume cold emails efficiently. It allowed us to double our outbound volume this quarter without doubling our infrastructure spend, solving the scaling costs issue. We are sending nearly 45k emails a month across 150 boxes, and the uptime is solid without any mass suspensions. The cost is predictable, averaging about $2 per mailbox, which makes planning a lot easier as scaling up doesn't come with surprises. The initial setup was pretty straightforward. Review collected by and hosted on G2.com.

What do you dislike about maildoso?

There's no mobile app. I'd like to be able to check domain health while I'm away from my computer. It's mostly about quick access. Sometimes you just want to check the domain or mailbox health when you're not at your desk. Review collected by and hosted on G2.com.
