OpenSRS Email Service Billing

OpenSRS Hosted Email services are billed monthly and debited from your reseller account balance at the end of each calendar month. This reference covers the pricing structure, how to calculate your mailbox count, where to view invoices, and how mailbox quotas affect what you pay.

Billing cycle

Email charges accrue throughout the month based on the mailboxes and forwards active on your account. OpenSRS debits the total from your reseller balance at month-end and issues an invoice statement in the Reseller Control Panel (RCP). Every reseller also receives an email reminder before month-end notifying you of the amount that will be billed for email services.

Pricing structure

A standard 5 GB mailbox is listed at $0.50 per month. Email forwards are listed at $0.02 per forward per month. Inbound and outbound messages up to 35 MB per email are supported. Do not set mailbox sizes outside the published tiers.

Calculating mailboxes on your account

The RCP lets you estimate your bill by exporting a CSV of email users with their assigned quota. For background on the export, see the related article on generating an email user CSV.

1. Sign in to the Reseller Control Panel.
2. Click Email and select Analytics. The Users page shows totals for mailboxes, filters, and forwards on the account.
3. For exact figures, use the Daily/Weekly/Monthly dropdown to download a snapshot of accounts in CSV format.

Viewing email invoices

The Statements section of the RCP provides access to the last 12 months of email invoices, including service descriptions, unit prices, and quantities.

1. Sign in to the OpenSRS Reseller Control Panel.
2. Click Billing & payments.
3. Select Statements and choose Email invoice.
4. Use the dropdown to select a Statement period.

Each reseller also receives an email reminder every month with the upcoming email invoice amount.

MAC .ADM users

Every reseller account has an automatic email user account used to access the Mail Administration Console (MAC) to manage hosted email. These .ADM users are created automatically for account administration, cannot send or receive mail, and are not billed.

Mailbox quotas and billing

Mailbox quota determines how much storage is available for messages and files. When a user reaches the quota, they can still send mail but inbound messages are rejected and bounced back to the sender. A user mailbox cannot exceed the domain max quota, and the domain max cannot exceed the company max.

Set quota in the Reseller Control Panel

1. Sign in to the Reseller Control Panel.
2. Click Email.
3. Navigate to the user account you want to modify.
4. In the Sending and receiving section, click Edit.
5. Set the quota size in MB to one of the tier values listed above, then click Save.

Set quota in the MAC

1. Sign in to the MAC interface.
2. Navigate to the user.
3. In the Sending and receiving section, update Quota (MB) to one of the tier values listed above.
4. Click Update at the bottom of the page.
