Instead of jumping between different dashboards to send a bulk SMS, trigger a voice notification, or check your remaining credits, you can just tell your agent what to do in plain English. It connects your AI client directly to the Submail platform, making it easy to manage transactional messages, HTML emails, and automated verification flows from a single interface. This is a huge win for teams who need to keep users informed without the friction of manual data entry. You can quickly query your mail or voice balances to ensure your services stay up and running, or fire off project-based templates with custom variables for dynamic messaging. By adding this to the Vinkius catalog, you're giving your agent the ability to act as a real-time communication coordinator. It handles the technical handshake so you can focus on the actual work of managing your users and operations. Whether you're sending out a large batch of notifications or just need to verify a single new user, your agent handles the API calls and status checks. This means you can move faster and avoid the headache of manual coordination. ## Tools ### get_mail_balance Check your current email credit balance.
