Each client gets a fully isolated workspace. Their inboxes don't see your inboxes. Their leads don't see your leads. You switch contexts from a single dropdown — fast enough to do it 20 times a day.
Don't want to teach your team DNS? Buy a dedicated infrastructure tier (10–500 domains, pre-warmed). Our ops team provisions, sets SPF/DKIM/DMARC, geo-segments by reputation, and gives you a Slack channel. 24–48hr SLA.
Your brand, your domain, your customer's experience. We're behind the scenes. Apex includes a custom subdomain on your domain, your logo in-app, and your support address as the contact-point.
Spin up a new workspace in seconds. See active campaigns, email volume, reply rate, inbox health per client. Suspend a non-paying client without deleting their data. Resume on payment.
