Billing

Nylas bills on the first of the month for the prior month’s usage. We calculate your usage by multiplying the number of active accounts by the effective price per account for your organization’s current billing plan. If your number of active accounts per month is less than or equal to the number of accounts included in your billing plan, we'll bill you the regular monthly rate for the plan. If you exceed the number of active accounts included in your plan, we'll bill you the regular monthly rate, with an additional prorated amount for each extra account. Your organization's prorated price per account is equal to monthly_rate / included_accounts.

An active account is an account whose billing_state changes to paid for any period of time within a given month. We don't prorate account usage within a month. An account's billing_state switches to paid the first time you authenticate it to the Nylas API. If you downgrade/cancel or delete an account, its billing_state will no longer be paid and you'll need to manually re-upgrade the account for it to become paid and active again.

An account is uniquely defined by both its email address and the server settings it uses to authenticate. This means that accounts will be counted more than once if the same email address was authenticated with different server settings. For example, if user@mail.com authenticates on 12/2 with server settings mx.mail.com, and then re-authenticates on 12/12 with server settings mailbox.mail.com, we'll count this account twice for December.

If re-authentication generates a new account_id, we recommend that you cancel the former account and use the new one moving forward to make sure we don't bill you twice. You can also ask your users to re-authenticate with the same server settings to avoid this issue. Check out our article on account re-authentication for more information. Accounts shared between multiple applications within your organization count as separate accounts.

A table to quickly identify when we charge an account is below:

billing_state	sync_state	Do we charge?
paid	invalid	Yes
paid	running	Yes
paid	stopped	Yes
paid	partial	Yes
paid	exception	Yes
cancelled	invalid	No
cancelled	running	No
cancelled	stopped	No
cancelled	partial	No
cancelled	exception	No
deleted	invalid	No
deleted	running	No
deleted	stopped	No
deleted	partial	No
deleted	exception	No

Data Centers

Nylas offers data residency to help you comply with legal requirements.

Nylas does not charge additional fees for using multiple data centers.
If you authenticate the same account in multiple data centers, you will be charged for each account.
