Connect
Connect: Paste your MailerLite API key (Bearer token from dashboard) — backfills subscribers, campaigns, and automations in under 5 minutes with real-time sync enabled.
Ask
Query: Ask 'Which subscriber segments have the highest engagement?' — your agent surfaces groups with open rates, click rates, custom field distributions, and historical activity trends across all contacts.
Act
Act: Say 'Move low-engagement subscribers to a re-engagement automation' — agent updates segment membership, applies tags, and triggers the sequence, logging every change with rollback options.

Read
Read: Subscribers (email, status, groups, custom fields, opens, clicks, subscription date), campaigns (open rate, click rate, bounce rate, unsubscribe rate, subject lines, sent date), automations (triggers, steps, performance), groups/segments (tags, targeting attributes), e-commerce data (orders, purchases, cart abandonment from Shopify/WooCommerce).
Write
Write: Update subscriber custom fields and tags, add/remove contacts from groups and segments, pause or activate automations, modify segment criteria, sync contact attributes from cross-platform behavior (e.g., tag high-value customers from CRM data).
Monitor
Monitor: Track campaign performance anomalies (sudden drops in open rates, spikes in unsubscribes), automation step completion rates, subscriber list growth/churn, deliverability issues (bounce rates), and segment size changes — alerts trigger when thresholds are breached.
Claude, ChatGPT, and Cursor can update subscriber custom fields, modify segments, pause underperforming automations, and sync contact attributes based on cross-platform behavior. When your agent adds a tag or updates a subscriber group, every change is logged with timestamp, reasoning, and rollback options in your audit trail.
