Auto-replenish
Keep backup capacity ready after swaps use it.
When InboxFlow moves sends to backup inboxes, those backups become active capacity. Auto-replenish keeps the replacement pool from running thin inside your provider, approval, and spend rules.
FAQ
Know what you are buying before checkout.
Why is billing every 4 weeks?
InboxFlow bills on a 4-week cycle so monitoring, swaps, and backup capacity work on a consistent operating rhythm.
What is a protected workspace?
A protected workspace is one client, brand, or outbound setup connected through a supported sequencer. It is the unit InboxFlow monitors and keeps backed by replacement capacity.
Are mailbox costs included?
No. You keep choosing and paying for mailbox providers. InboxFlow manages weak-inbox detection, swaps, backup tracking, replenishment rules, and reply reporting around them.
Can I cancel?
Yes. The Stripe billing portal lets you manage payment methods, invoices, billing details, and cancellation.
