Prices in USD, excluding taxes. Inbound counts reset at midnight UTC. When a workspace hits its daily inbound cap, the sending server is told to retry tomorrow (452), so mail is deferred rather than lost. Larger limits and longer retention are available on custom plans: contact sales@mailcatchr.com.
