Reseller accounts

Fastmail reseller accounts are available to all account holders, but they are most suitable for IT professionals who wish to offer email hosting as part of their services.

A reseller account is an account that is able to create and manage other accounts. These sub-accounts can be individual users; or multi-user accounts such as businesses, or other organisations.

Billing models

We offer two billing model options for sub-accounts. A reseller can choose which model is most appropriate for each sub-account: they don't have to all be the same type.

The reseller bills the sub-accounts

The reseller manages the sub-accounts. The sub-accounts need to contact the reseller to make administrative changes. (Resellers do not set up any admin users within the sub-accounts).

Fastmail bills the reseller the standard fee for the sub-accounts. Resellers then charge their sub-accounts a fee for support, as well as pass on the fee to the sub-accounts for their email service.

This is ideal if the sub-account doesn't have time or expertise in managing their mail accounts and wants or needs the reseller to provide that support. It requires the reseller to have their own payment collection system.

Fastmail bills the sub-accounts

The sub-accounts are billed directly by Fastmail. The sub-accounts can administer their own accounts, resulting in little/no management overhead for the reseller. But no mark-up can be passed on to the sub-accounts.

If the sub-accounts needs help, they contact the reseller who then (potentially) charges a fee for support calls.


The advantages of using a reseller account (instead of setting up all the users within a single account) are:

How to become a reseller

Once you have a paid (non-trial) account, raise a ticket and our support team will convert you into a reseller. Make a note in the support ticket of your expected volume of sub-accounts so that our sales team can discuss bulk discount reseller pricing.

Create a sub-account

Use the Settings → Reseller screen for managing sub-accounts.

  1. Create the new account and name it.
  2. Edit the account to select the Plan this account is on.
  3. Use "Change Billing Details" to select whether this account is billed through you, or directly to the client. If the account is paid by the client, enter their payment information.
  4. (Optional) Set up any domains this account is using.
  5. Set up any policy details: their company name, custom login page and their disclaimer.
  6. Add users.
  7. (Optional) Add aliases.

If you are billing the sub-account through you, you may choose not to add any admin accounts for the sub-account as this will give them access to the Billing screens where they can see, and change, payment information for themselves.

If the sub-account is being directly billed by Fastmail, we recommend giving them an admin accounts to let them manage their billing for themselves and other administrative tasks, including adding in all their own users.


For sub-accounts that are being billed directly by Fastmail, you don't need to do a thing. Our system will automatically invoice and receive payment for the sub-accounts.

If you're invoicing your own sub-accounts, you can view their charges by going to Settings → Reseller, selecting the sub-account and on their Billing & Plan page, viewing their invoice. Invoicing and payment of the sub-account will need to be handled outside of Fastmail.

Remove a sub-account

To remove a sub-account, you need to first delete all their users, then delete the sub-account.

To delete all the users, go to Settings → Reseller, select the sub-account, go their Users & Aliases page. Enter your reseller password to unlock the screen, then select the users to delete and remove them using the Delete button.

Once the users are gone, navigate to the sub-account's Billing & Plan screen. At the bottom, select to delete the account: enter your reseller password to confirm. If there are any funds remaining in the account, they will be transferred back to the reseller.

Lock a sub-account

To disable a sub-account (either temporarily, for non-payment or breach of service; or in preparation for deleting them), you need to disable logins on all the users in the sub-account.

Go to Settings → Reseller, select the sub-account, go their Users & Aliases page. Enter your reseller password to unlock the screen, then select all users, Edit them and Disable them.

Create a custom login page

Reseller accounts can use the policy settings page to create a custom login page, company name (for invoicing), email footer and control whether shared contacts are editable only by administrators.
