The verdict Side by side Plans and pricing Who each is for Other options

The verdict

Choose by channel, not by feature count. Instantly wins the moment cold email is your primary motion: the built-in warmup keeps your domains landing in the inbox, unlimited sending scales without per-seat penalties, and the lead database means you're not stitching a separate data tool into the workflow. It does one channel and does it properly, email only, no LinkedIn.

Kanbox wins when LinkedIn is where your buyers are. It handles the full LinkedIn loop, scrape, connect, message, then routes replies into a Kanban pipeline so a solo founder can actually manage the conversations rather than lose them. At 27 EUR to start it's the cheaper entry point, but it bills per LinkedIn account, so the cost scales with how many profiles you run.

For most lean B2B founders the honest move is to start with the channel you already get traction on. Running both? They complement rather than compete, Kanbox for LinkedIn touches, Instantly for the email volume underneath.

Who each is for

Choose Instantly if…

Pick Kanbox if your pipeline runs through LinkedIn. You're a solo founder, sales rep, recruiter, or small agency who prospects by scraping Sales Navigator, sending connection requests, and messaging, and you want a CRM to track those threads without paying for a separate tool. The Kanban pipeline and unified inbox are the real draw: outreach and pipeline management in one workspace. It's the cheaper starting point at 27 EUR, but remember pricing is per LinkedIn account, so map your seat count before committing.

Choose Kanbox if…

Pick Instantly if cold email is your main outbound channel and you want volume. You're running high-send campaigns across multiple inboxes, you need automated warmup so those domains stay deliverable, and you'd rather have a lead database built in than bolt one on. Founders and agencies who think in terms of sends-per-day and reply rates, not connection requests, belong here. Just know the Lead Finder and CRM are billed separately from the core Outreach plan, so price the add-ons you'll actually use.
