Inboxkit Reviews 

Caution purchasing Email Inboxes from Inboxkit. I purchased 20 email boxes just to test their service. I wanted to test email sequencing from Apollo and Clay. There is not direct process for integrating mailboxes purchased from Inboxkit to either of these providers I mean it's Apollo and Clay - a couple of never heard before providers!). The only process is manual - one at a time - not exactly scalable. I asked for a refund and was told Inboxkit does not issue refunds. I even reached out to the CEO - no help. Buyer Beware!

My experience with InboxKit has been extremely frustrating, both with the service and the support.

I paid USD 99 on October 15, 2026, for the monthly Agency plan, which included 30 mailbox slots. My understanding was that the subscription would remain active until November 16. However, the plan was removed after approximately 24 hours and was never properly restored.

When I contacted support, they moved my mailboxes onto their wallet credit system instead of reinstating the Agency plan I had purchased. That workaround worked for a few days, but the problems returned. I then had to contact support again and explain the same payment and subscription issues.

By November 4, 20 days after my payment, my account showed:

No active plan

Zero wallet credits

30 total mailboxes

Zero active mailboxes

My billing history clearly shows the $99 Agency plan invoice as paid. Despite this, I have been left chasing support to get the service working.

The support experience has made this even more frustrating. I have repeatedly explained what I purchased and provided screenshots, but the conversations have not produced a lasting solution. One support conversation was closed on the assumption that everything was working, even though my mailboxes were still inactive.

In the latest response, support told me that eight mailboxes across two domains had failed to renew and that recovering them would cost 26 credits. That response did not resolve my concern: I had already paid for a monthly plan covering 30 mailbox slots, and my dashboard showed zero active mailboxes.

I understand that technical problems can happen. What I find unacceptable is having to keep following up about the same unresolved issue while my paid subscription remains unavailable. I run a business, and I should not have to spend time every week explaining why a service I have already paid for needs to work.

I have now requested a full refund of the $99 payment because the monthly service was not provided as agreed. At the time of writing, the issue remains unresolved.

Based on my experience, I cannot recommend InboxKit to businesses that need reliable mailboxes and support that follows an issue through to a confirmed resolution.

An InboxKit outage left my campaign partially sent, and my Instantly subscription expired while I waited for a fix. After nearly a week of support saying they're checking with the team, there's still no resolution or approval to cover the extra month needed to finish.

Outages happen. What matters is how a vendor helps customers recover. InboxKit hasn't done that.
