Inboxkit Reviews & Product Details

I use Inboxkit as my primary provider for cold email, and it’s been great. I like that its features feel unique compared with other options. I can swap domains in a few seconds and easily get pre-warmed Azure inboxes, which is a big plus for me. I also like that Inboxkit connects with my SendKit, so I can reach out to the SendKit team if I have an issue and get help. Setup was very easy and super quick, and I didn’t have to put much effort into switching everything over. It’s great for managing my clients’ inboxes. Review collected by and hosted on G2.com.

Sometimes support can be a little annoying, depending on who takes it, though in general I think it’s pretty good. I’d also like a way to keep newly bought domains warm even when they aren’t attached to an inbox. I think you need to know and understand cold email to use Inboxkit, so I wouldn’t recommend it to a new client just yet, depending on the type of client. Review collected by and hosted on G2.com.

As someone sending over 10K+ emails a month, managing deliverability and mailbox setup used to be an absolute nightmare. I switched to InboxKit, and it has completely transformed my outbound workflow.

The biggest win for me is how flawlessly it integrates with Instantly. Exporting my ready-to-go mailboxes straight into my campaigns takes seconds. The setup is incredibly easy to use - what used to take hours of manual DNS mapping and setting up individual Google/Microsoft accounts now happens automatically in a few clicks.

The only real downside is that it is a bit expensive to start off. Because they use fixed package minimums rather than a single pay-as-you-go setup, the initial upfront cost can feel a bit steep if you are just dipping your toes in. Review collected by and hosted on G2.com.

What I like most about InboxKit is how easy it makes setting up and managing multiple mailboxes for cold outreach. The streamlined setup, DNS authentication, and centralized mailbox management save a lot of time and simplify the process of managing email infrastructure. It’s a practical solution for scaling outreach campaigns without dealing with too much technical complexity. Review collected by and hosted on G2.com.

There is room for improvement in deliverability reporting and mailbox reputation monitoring. More detailed insights into inbox placement, domain health, and mailbox performance would make it easier to identify and resolve issues. Overall, the platform is useful, but enhanced reporting and analytics would make the experience even better. Review collected by and hosted on G2.com.

I love how easy they make it to set up email accounts. Traditionally, if you were to do this manually, it'd take forever, and it'd be the biggest headache having to manage all the different inboxes at the same time. With InboxKit, it's extremely simple to just set everything up, streamline everything, and get them out to my sequencers. Review collected by and hosted on G2.com.

I haven't really found anything that I've disliked with Inbox Kit so far. I wish that the payments could take Amex. I think that's the biggest thing: I just wish their processor took Amex, but it's not that big of a deal. Review collected by and hosted on G2.com.

I really appreciate Inboxkit's support, which is top-tier and always quick to respond. They take time to explain things properly, and if I need more help, I can easily book a call for the next day. It reassures me that I'm not left on my own when something goes wrong. Additionally, the deliverability is great, helping me achieve up to 5% reply rates on my campaigns. Setting up accounts is straightforward without major issues, and any problems get resolved swiftly by their support team. Also, the initial setup of Inboxkit was very easy, and I'd definitely recommend it to others. Review collected by and hosted on G2.com.

The UI can be confusing sometimes, like trying to find certain things is a bit complex. It would be helpful if things were easier to navigate. It would also be great if there was a feature where you could give commands and someone could set things up in your account, rather than having to do it manually.

Customer support is truly top-notch. They add you to a Slack channel, which makes it easy to communicate without having to go back and forth over email. Deliverability has also been consistently great. Review collected by and hosted on G2.com.

Nothing really comes to mind. They’re constantly updating features and they take feedback in a positive way, which I appreciate. Overall, it’s been pretty good. Review collected by and hosted on G2.com.

I really appreciate the convenience Inboxkit provides. It makes it very easy and seamless to set up cold email inboxes without taking much of my time. I also like their customer support, which is really helpful when any problems come up. Review collected by and hosted on G2.com.

I didn't like the use of wallet billing on top of mailbox slots.

I feel like they should charge for mailbox slots instead of using both that and the wallet credit system. Sometimes it leads to double billing but support sorts it out.

However they've changed their billing model to be flat pricing via wallet now so it's much more straightforward Review collected by and hosted on G2.com.

I like that Inboxkit manages our entire deliverability stack efficiently in one place. I appreciate its very good API and MCP features, which allow us to integrate seamlessly with AI agents and speed up our execution significantly. The support for multiple mailbox platforms is also a big plus, and it's more cost-effective compared to other options. The setup was pretty easy and, although the integration process took a bit longer due to our scale, it was manageable. Review collected by and hosted on G2.com.

I wish inboxes could be created faster, even instantly, although I understand that might not be possible. Also, the connection process can sometimes be a bit slow and complex, especially on the integration side, which could be improved. Review collected by and hosted on G2.com.

Inboxkit saves me a lot of time and headache. It makes it very easy to manage many mailboxes, and DNS configuration is piss-easy, especially with Cloudflare. I don’t have to configure DNS records manually or manage each mailbox separately, so I can focus on my email campaigns, advertising, and marketing instead of technical configurations. I also found the setup simple, straightforward, and quick. The Cloudflare integration was fast, and the web interface made it easy to look for things. Review collected by and hosted on G2.com.

My main downside is the pricing flexibility. I don’t enjoy the credits mechanism and would prefer straightforward pricing in USD, with clear monthly costs and no need to calculate credit usage. Review collected by and hosted on G2.com.

I like Inboxkit’s clean design and the clear, fast UX. It gives me a direct interface without clutter, which makes it easy to navigate. I also find the mailbox warming feature valuable, especially the mailbox overview with scores. Overall, these features make Inboxkit straightforward to use and informative for my needs. Pricing is markt confirm. Review collected by and hosted on G2.com.

I find it strange that SmartLead requires a username and password instead of an API key to connect with Inboxkit. Once connected, it automatically starts the warming process unless I manually clear all settings. There doesn't seem to be an option to stop the warming up process within SmartLead, which is a bit frustrating. Review collected by and hosted on G2.com.
