1. Connect Domains: <\/strong>You can connect your existing domain or buy a new one directly inside InboxKit.<\/p>\n\n\n\n

You can add up to 500+ inboxes per domain<\/strong>, depending on your plan.<\/p>\n\n\n\n

3. Warm Up Automatically: <\/strong>InboxKit runs an AI-powered 14-day warmup<\/strong>, sending and replying to real messages across verified accounts. <\/p>\n\n\n\n

This gradual increase in volume builds trust with ISPs and achieves a 95% inbox placement rate<\/strong> once completed.<\/p>\n\n\n\n

4. Integrate and Send: <\/strong>InboxKit integrates with 15+ outreach and CRM tools<\/strong>, including Instantly, Smartlead, Lemlist, Apollo, and HubSpot.<\/p>\n\n\n\n
