Every connector starts free. Its plan raises what it can do, and each is billed on its own.

An action

One call that reaches a mailbox - up to 100 threads at once - or fetches a file

Counted

Once for the whole account - every mailbox and every AI app together

Window

Any rolling 24 hours and, without a plan, any rolling 30 days - not a calendar day or month

Free

25 actions in 24 hours, up to 250 in 30 days

Plan

1,000 actions on Standard, 10,000 on Plus, with no monthly limit

Not counted

Calls that are refused or fail

Next free action

When the oldest counted one turns 24 hours old - 30 days old at the 30-day limit - rounded up to the minute

Multi Calendar

No daily allowance. A ceiling of 1,000 actions in any 24 hours, which no plan changes

Over the limit

The call is refused before any mailbox is reached, with this text:

allowance_spent: The person's account page: https://lumman.co/mcp/account/multi-mail This account has used its 25 actions in the last 24 hours. One action comes back at 14:32 UTC, 3 hours 12 minutes from now, and each of the others 24 hours after it was made. Do not call Multi Mail again before then unless the person asks you to, and tell them so now.

A file fetch

HTTP 429 {"error":"allowance_spent", ...}

Plans and prices

At the free limit Claude and Claude Code also hear that a plan raises it. No answer names a price

After a payment

The next call is let through once the payment is confirmed - not on the return from checkout
