Success.aimaster inboxRated 4.6 out of 5 on Trustpilot. Every review below is unprompted and verified.
The team was excellent, very supportive and whenever we needed help with campaigns/getting new accounts etc they made the process super simple and effective
Simple to set up, inboxes work as expected, and support actually replies. That's most of what I need from an inbox provider. Happy with it.
Great service from start to finish, everything made easy and they're always only a text away, would highly recommend!
I love that it's a relatively smaller company. I also have direct access to the founder, he responds fast, and I have a lot more customization opportunities to be able to have exactly what I want. Furthermore, they're on top of all trends and send continious updates about everything that's needed. Definitely deserves a 5-star review!
Thanks to the infra they've set for us we had 0 emails landing in spam out of 10s of thousands so far. Jason and his team are providing a very reasonable price for google workspace accounts and a very good and quick support on Slack.
Service delivery and communication are excellent. This is my second time working with Jason and the team and both experiences have been great. Same-day delivery and fast responses. The domains and email cold outreach works perfectly with zero friction.
Got great results the first month already with about 30 booked calls for our AI Services in a local market. Alexander specifically has been great to work with, very responsive and really knows what he is doing. If you need leads and meetings via cold email I highly recommend them.
It took me a bit to get acclimated to the workflows of Frostmailer but now that I got it, they've been a great and super helpful partner. I'm new to setting up cold email infra so they've been a great resource in getting everything going.
Great team, inboxes were great, lasted much longer than other providers. Support team also great and very easy to deal with. Highly recommended if you want inboxes.
We've tried multiple of these services and Frostmailer has been the best so far. The emails were super high quality and a fire sale. Customer support was also extremely helpful and patient. Highly recommend.
I've tried pretty much every cold email tool out there, and Frostmailer is hands down one of the best. Deliverability is solid, campaigns run smoothly, and the support team actually responds quickly. It's helped us land serious leads consistently.
They work fast, you will get inboxes setup done in less than 24 hours and they are experienced. Everything works perfectly.
Pulled straight from client dashboards, nothing rounded up and nothing invented.
30 day window. Open tracking off, which is why opens read zero.
4 week window, campaign active.
4 week window. Highest reply rate of the three, on a mixed estate.
Real campaigns run on Frostmailer infrastructure. Results are not typical and depend on offer, list quality and sending discipline.
Takes under a minute. No call required to get started.
About 5 minutes. Tell us volume, domains and sequencer.
Azure live in 24 hours, or about 6 hours for pre-warmed. Google in 24 to 48 hours.
Your whole outbound stack stood up on Azure, handed over after 14 days. You pay for domains and setup. Scripts, leads, SmartLead and support are free on top.
Testing a new product and want to know whether cold email will actually work for you? Completely new to outbound and would rather not learn it the hard way? These two packages are built for exactly that. We stand the whole system up, launch the campaigns, and hand you the keys after 14 days.
Enough infrastructure to prove the channel works.
Three times the volume, three times the domains, for 70 percent more. The one most teams end up on.
Add any of these to Basic or Advanced. The system is yours to run from day 14.
Answers your inbound replies in your voice and books them straight into your own Calendly.
Sets ordered, warmed and swapped on a six week cadence so reputation never ages out.
Top up beyond the initial 10k verified leads whenever you need more volume.
The full cold email course and community, included with every package.
Mailbox reputation decays. Rotation replaces each set before it does, so you never take the deliverability hit that comes from sending on tired infrastructure.
A fresh set goes live. You send at full volume on newly warmed infrastructure.
The next set is ordered. Domains bought, inboxes created, DNS configured. You approve in Slack with one click.
The new set warms while the current set keeps sending. No pause, no volume dip.
The swap. Warmed set takes over, old set cancelled, clock re-arms for the next cycle.
One monthly payment covering the whole cycle. The clock runs itself, and you approve each swap with a single click in Slack.
Backend rotation system running a six week cadence per set, with no manual tracking on your side.
Swap notifications and one click approval on every cycle, in the channel you already use.
Tenants and domains created, authenticated and warmed for each new set before it goes live.
Old sets cancelled automatically on swap, so you never pay for infrastructure that stopped sending.
Full breakdown, the live rotation dashboard and sign-up all live inside the app.
Flat 10 percent of the recurring subscription, every month for the first 12 months of each customer you send us. Every Frostmailer account is enrolled automatically.
Yes. Every Azure and Microsoft mailbox includes the .com domain, bought and configured for you.
2 to 3 per inbox per day. Scale by adding inboxes and domains, never by pushing existing ones harder.
Standard is live in 24 hours, then warms for two weeks. Pre-warmed is uploaded and sending in about 6 hours.
Tenants come in 25, 50 or 100 accounts, so you can size the order to your volume.
EmailBison for sending and PlusVibe for warm-up. Smartlead works well too. We do not advise Instantly with Azure inboxes.
No. Google full admin does not include the domain. You can buy domains inside the app in the same order.
Up to 15 per inbox per day, on a two week warm-up.
24 to 48 hours for standard accounts. Pre-warmed accounts are ready in about 6 hours.
Yes. Every Google plan is full admin with US IP accounts and DNS configured.
