It was a good sales pitch so I was excited to use the platform but they were not representing their platform properly. It was pretty difficult to transfer domains into their platform. It takes 48-72 hours to get domains in thru support (unless you pay extra using Mailscale), then you have to create and export Mailboxes into your own platform manually. So an extra 2-3 wait time vs when I was using Zapmail - it was basically a 10 minute set up. The self-healing mechanism that they advertised just didn't work at all for me. They said it was because Google has new spam updates but I don't know.

So I found out that a lot of my emails were going to spam. I'm going to try to get a refund because they guarantee 99% deliverability. Update; they gave me a partial refund of $1,000 of the $3,000 I paid.

I don't recommend going with this company. They say unlimited mailboxes but they go by sending volume so you're still not getting unlimited mailboxes. Although I mean it is but you're getting capped at how much you could send.

I would recommend going with Zap Mail or using Instantly.ai or another sending provider's done for you infrastructure. It may be more expensive but at least it will work.

I love the system and the support given by Mailscale. Everything about it works well for me, and I highly recommend it. Setting it up was really easy, which made the process smooth!

The ease of getting a reliable network of email addresses live and ready to send is locked in. Their cost per lead is much lower than buying direct from the major lead companies.

Easy-to-Use Platform with Outstanding Hands-On Support

I've been using Mailscale for several months now, so I've had plenty of time to form a well-rounded opinion. The platform itself is straightforward and easy to navigate — I was able to get up and running quickly without a steep learning curve, which was important to me as a busy business owner.What truly sets Mailscale apart is the level of support. Their team is responsive and available on Slack whenever I have a question or run into something. I also meet with Baris on a weekly basis, and those sessions have been incredibly valuable. He brings sharp insights, takes the time to understand what I'm working on, and is genuinely easy to work with — both knowledgeable and personable.I noticed a handful of one-star reviews before signing up, and I'll be honest — my experience has been the complete opposite. The software works as advertised, and the team backs it up with real, accessible support. I'd encourage anyone considering Mailscale to give it a fair shot and judge based on their own experience.

Helpful Tool for Scaling Campaigns

We’ve had a good experience with Mailscale overall. The system is easy to use, support team is helpful when needed, and it gets the job done for outbound cold email outreaches/campaigns. A reliable option in this space. There is one shinning star on their team, and that is Baris Kirat. He takes the time out to review your campaign settings, and assist you in areas that need improvement. His insight was most helpful. If I could give him specifically a 5 star rating for his impeccable customer service and extensive backend knowledgebase, I would. All and all, solid platform.

Been 100% Pleased

Been 100% pleased with the results from Mailscale. We are on a recurring email campaign given its success. Baris has been our key contact with Mailscale and I'm truly impressed with his knowledge and professionalism.

Deliverability Issues with Shared IP Addresses

Only used MailScale for 1 month, first week was OK, by week 2 deliverability was <50%. MailScale then moved us to a new Data centre and IP address, when we started sending emails again 3-4 days later deliverability was again <50%......MailScale support is also poor, nothing is resolved quickly 3-4-5 days.

Great experience, Baris is a legend

Been using Mailscale for about 4 months now and honestly really happy with it.Infrastructure has been solid. Deliverability is where it needs to be, campaigns are running smooth, no major headaches. Setup was quick and everything just works which is all you really want from this stuff.The real standout though is Baris. Guy goes above and beyond. He's always in Slack, sending Loom videos with tips on copy, spintax tweaks, things to watch out for. Not just "here's your login, good luck" energy. He actually pays attention to what's going on and gives you useful feedback to make things better.That kind of support is hard to find.Yassin runs a tight ship. Small team, no BS, they just get it done. Respect.If you're looking for cold email infrastructure that actually works with people who actually care, these guys are solid. Would recommend.

Stay Away from Mailscale - total scam

I paid for Mailscale in November for a managed outbound email service. Domains, DNS, and authentication are explicitly part of what they sell.It is now mid-January, and every single domain they provisioned is still failing DMARC.This is not a user setup issue. I did not configure DNS. These domains were purchased, registered, and provisioned by Mailscale. Support told me in December that the DNS issues were fixed. That was false. Independent tests across multiple tools still show DMARC failure the moment inboxes are connected.This makes the service unusable. You cannot warm up inboxes or run outbound safely when DMARC is failing. Any time spent “warming” under these conditions is wasted or damaging.Support was slow and resolution claims did not match reality. After weeks of delay, I had to escalate directly to the founder to get basic answers.If a company selling managed outbound infrastructure cannot get DMARC working after months, that is not a minor issue. It is a core operational failure.Do not rely on this service if you need dependable outbound email, especially at scale.
