Pricing questions
Is the free plan really free?+
Yes. The Free plan includes 5 inboxes and 5,000 emails per month with no credit card. It's a hard cap — upgrade to Pro when you need more.
How does overage work?+
Paid plans bill overage per 1,000 emails beyond your included volume — $2.00 on Pro, $1.50 on Scale, and $1.00 on Business. The Free plan is a hard cap with no overage.
How much attachment storage do I get?+
Generous storage at every tier — 5 GB on Free, 20 GB on Pro, 200 GB on Scale, and 600 GB on Business — so agents keep full email and attachment history searchable without add-ons. That's more storage than comparable agent-email plans at every tier.
What counts as an inbox?+
An inbox is a real, addressable email address you provision for an agent. Your plan sets how many you can have active — from 5 on Free to 15,000 on Business, and custom on Enterprise.
Do you price SMS and iMessage?+
These channels are in early access and aren't self-serve yet. Talk to our team and we'll share messaging pricing for your use case.
What does Enterprise add?+
Enterprise adds custom inbox and email volume, dedicated sending IPs, an SLA, and SSO. Contact us for a quote.
