Message Viktor in Slack like you'd message a teammate. "Clean this list of email addresses with Postmark and flag the invalid ones." "Check Postmark for our sender reputation and flag anything that could hurt deliverability." Plain English, any tool.
Viktor opens Postmark, runs the work, and posts back what changed. Sensitive actions wait for your approval. Everything is logged. You stop doing the work and start reviewing it.
A Postmark AI agent is an AI that connects to your Postmark account and completes work in it - it doesn't just answer questions about Postmark, it takes the actions. Viktor is that agent: an AI employee that works in Postmark on your behalf and delivers the finished result in Slack or Microsoft Teams.
Unlike workflow builders such as Zapier or Make, there is nothing to configure - no triggers to map, no workflows to maintain. You describe the outcome in plain English, and Viktor picks the right Postmark actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
Postmark is a fast and reliable email delivery service that enables you to send transactional and marketing emails and get them to the inbox on time, every time.
