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.
