InboxKit allows you to switch between subscription plans at any time based on your team size, sending volume, or feature needs. You can upgrade to a higher plan or downgrade to a lower one with just a single click.
Step-by-Step: Changing Your Subscription Plan
Step 1: Go to the Subscription Page
Navigate to:
Sidebar → Subscription
This opens the page where all available plans are displayed.
Step 2: View Your Current Plan
Your active plan will show a “Current Plan” button (greyed out).
Step 3: Upgrade / Downgrade (Switch Plans)
To switch to another plan:
Click “Upgrade to Agency”
Or click “Upgrade to Enterprise”
If you're on a higher plan and want to downgrade, you will see a Downgrade button on lower plans.
Once you click the desired option, your subscription will update immediately.
What Happens After Switching Plans?
The difference in pricing is automatically handled by Stripe.
Upgrades are not prorated — you're charged the full price of the new plan immediately. Any overpayment for the remaining days on your old plan can be credited to your wallet as an adjustment rather than refunded to your card.
Your mailbox slot limits adjust instantly.
Your billing cycle continues normally (monthly or yearly depending on your selection).
No disruption to your domains, mailboxes, or sequencer setup.
