Postmark
When your AI agent resolves a customer issue, it should follow up with a confirmation email that actually lands in the inbox. Postmark's transactional email API delivers messages with 99%+ deliverability, and your agent sends them mid-conversation, tracks opens, and monitors bounces.




Your AI agent sends emails through Postmark's deliverability-optimized infrastructure, tracks performance metrics, manages templates, and monitors spam complaints, all without leaving the chat.
Postmark
See how businesses use AI agents with Postmark to send transactional emails mid-conversation, monitor deliverability, and keep email operations running smoothly.
A customer reports a billing issue in your chatbot. Your AI Agent resolves the problem, then immediately sends a confirmation email through Postmark using the billing resolution template with the customer's name, adjusted amount, and reference number. The customer sees the email in their inbox within seconds. Your support team has zero follow-up work.
Your email operations manager asks the AI agent for a deliverability report. The agent pulls Postmark's delivery stats, bounce rates, and spam complaint counts for the past 30 days, identifies a spike in soft bounces from a specific domain, and flags it for investigation. The ops team catches the issue before it impacts sender reputation.
A marketing team member wants to update the subject line of an order shipped email. They tell the AI Agent the change. The agent retrieves the current template from Postmark, updates the subject field, validates the template with sample data to confirm it renders properly, and saves the update. No developer needed, no Postmark dashboard login required.

FAQs
The agent calls Postmark's Send Batch with Templates endpoint, passing the recipient email, template ID, and merge variables collected during the chat. Postmark processes and delivers the email within seconds. The customer receives the email while still in the conversation.
Postmark separates these into message streams. The agent can send through your transactional stream (order confirmations, password resets) and broadcast stream (announcements, newsletters). Configure which stream each template belongs to in your Postmark account.
Tars requires a Server API Token from your Postmark server. This token provides access to send emails, manage templates, retrieve stats, and configure webhooks for that specific server. Each Postmark server has its own token, so you control scope precisely.
No. Email content and recipient details are passed directly to Postmark's API during the conversation. Tars does not cache email bodies, addresses, or tracking data. All email records live in your Postmark account's activity feed.
Yes. The agent queries Postmark's bounces endpoint and delivery stats to determine the fate of sent emails. It can filter by email address, bounce type, and date range. If an email bounced, the agent reports the reason (hard bounce, soft bounce, spam complaint).
The agent can submit raw email content to Postmark's SpamAssassin API to get a spam score before sending. If the score is high, the agent warns about elements that might trigger spam filters, like certain phrases or formatting. This pre-flight check helps maintain your sender reputation.
Direct API integration requires developer time and code changes for every new email workflow. With Tars, your team configures email sending through conversation flows visually. Non-technical team members can trigger emails, check stats, and manage templates without writing code.
Yes. The agent can create new templates with subject lines, HTML bodies, and text versions, edit existing templates by ID, validate templates with sample data, and list all available templates. Template management becomes a conversational task rather than a dashboard workflow.
