Copy-paste prompts for Mailchimp × Claude
Add Porter MCP to Claude (paste https://mcp.portermetrics.com/mcp), open a new conversation, and paste any prompt below.
Weekly Mailchimp exec snapshot
Generate a weekly exec summary for the last 7 days. Include: total campaigns sent, average Campaign open rate, average Campaign click rate, total E-commerce total revenue, total E-commerce total orders, current List all-time open rate, and List average unsubscriptions per month trend. Compare each metric to the prior 7-day period. Flag any metric that dropped more than 10%. Output as a 5-bullet summary followed by a 3-row table: metric | this week | last week | change %.Campaign revenue attribution ranking
For every campaign sent in the last 90 days, pull Campaign name, Send time, Campaign open rate, Campaign click rate, E-commerce total revenue, and E-commerce total orders. Rank by E-commerce total revenue descending. Highlight any campaign in the top 10 by Campaign open rate that generated zero E-commerce total revenue. Output as a ranked table with a 1-sentence insight per campaign about what the send time or engagement pattern suggests.Subject-line fatigue tracker
List every campaign sent in the last 60 days with Campaign name, Subject line, Campaign open rate, Campaign click rate, Unsubscribed, and Campaign bounce rate. Group campaigns by subject-line pattern (question, emoji, number, urgency word, personalization). For each pattern, calculate the average Campaign open rate and average Campaign click rate. Flag any pattern where Campaign open rate dropped 20% or more from the first half to the second half of the period. Output as a pattern summary table plus a ranked list of the 5 worst-performing subject lines.List health trajectory & audience decay
Show the monthly trend over the last 12 months for: List all-time open rate, List click rate, List average unsubscriptions per month, List hard bounces, List soft bounces, List cleaned count since send, and List rating (Number). Flag any month where List average unsubscriptions per month grew faster than list growth, or where List rating (Number) dropped by 1 point or more. Output as a time-series table plus a 3-bullet risk assessment: green / yellow / red.Deliverability alert monitor
Scan the last 30 days. Alert if any of these thresholds are breached: Campaign bounce rate > 5%, Campaign hard bounces > 2% of emails sent, Campaign abuse rate > 0.1%, or List hard bounces increased 50% vs the prior 30-day period. For each alert triggered, list the affected campaigns or lists, the exact value, the threshold, and a 1-sentence recommended action (clean list, pause sends, or review content). Output as an alert table with severity color.Engagement anomaly scan vs industry
Compare the last 90 days to the prior 90-day period. Calculate the change in average Campaign open rate, average Campaign click rate, List all-time open rate, and List click rate. Compare each to the Industry open rate and Industry click rate for the same period. Flag any metric that dropped more than 15% period-over-period or fell below industry benchmark. Output as a 4-row comparison table (metric | current | previous | change | vs industry | status) plus a 2-sentence diagnosis of the most likely cause.Email + e-commerce cross-module blend
For the last 90 days, blend campaign and e-commerce data: list Campaign name, Campaign open rate, Campaign click rate, E-commerce total revenue, E-commerce total orders, and Total spent. Calculate revenue per email sent and revenue per unique click. Rank campaigns by E-commerce total revenue. Identify the top 3 campaigns by revenue that had below-median Campaign open rate — these are hidden winners driven by click quality, not list size. Output as a ranked table plus a 3-bullet takeaway.Multi-list agency rollup
Roll up all lists for the last 30 days. For each list, output: List name, List total members, List all-time open rate, List click rate, List average unsubscriptions per month, List hard bounces, and List campaign last sent date. Calculate a health score (0-100) based on engagement, churn, and recency. Rank lists by health score descending. Flag any list with List campaign last sent date older than 14 days or List hard bounces > 3% of List total members. Output as a ranked health table plus a 1-sentence recommendation per flagged list.Send frequency vs subscriber fatigue
Analyze the last 90 days. For each week, count the number of campaigns sent and calculate the average Campaign open rate, average Unsubscribed per campaign, and average Campaign bounce rate. Correlate weekly send volume with the following week’s Campaign open rate and List average unsubscriptions per month. Identify the send-frequency threshold where additional campaigns cause Unsubscribed to accelerate. Output as a weekly table plus a 2-sentence pacing recommendation.Automation sequence engagement drop-off audit
Audit every automation active in the last 90 days. For each automation, list: Automation name, Automation type, Automation status, the number of campaigns inside it, average Campaign open rate across those campaigns, average Campaign click rate, total E-commerce total revenue, and total E-commerce total orders. Flag automations with Automation status = paused or save that previously generated E-commerce total revenue > $500. Also flag any automation where Campaign open rate dropped 25% from the first campaign to the last. Output as a ranked table by lost revenue potential plus a restart-priority list.
Security
Mailchimp MCP safety
Porter authenticates to Mailchimp with the read-only scope you already approved for your reports. Anthropic Claude queries Porter — not Mailchimp directly — so every conversation is rate-limited and cached at Porter side. No new permissions, no ban risk.
- Caching. Porter caches recent query results for 15 minutes per (account, field set) so repeated Claude prompts don’t hit the API again.
- Batching. Multiple field requests are merged into a single API call when possible (max 100 items per call where supported by Mailchimp endpoints).
- Backoff & retry. Exponential backoff on 429 responses (1s → 2s → 4s → 8s).
- Per-account quotas. Porter tracks per-account daily usage and pauses queries before hitting 80% of observed safe thresholds.
- Read-only enforcement. Porter never requests write scopes from Mailchimp, so even compromised tokens cannot modify campaigns, lists, or subscriber data.
- Audited tools. The MCP exposes 6 read-only methods:
get_blend_id,list_accounts,list_categories,list_data_sources,list_fields,query_data.
GDPR compliant · 1,600+ marketers trust Porter with their Mailchimp data.

No. Paste one URL into Anthropic Claude’s MCP settings. No API tokens, no JSON-RPC, no local servers. If you can copy and paste, you can connect Mailchimp to Claude.

Can I create or edit campaigns from Claude, or is this read-only?
Read-only. Anthropic Claude can query, analyze, and summarize. It cannot pause campaigns, change budgets, edit ad copy, or modify targeting. This is by design for safety.
