AutoEmails MCP For ChatGPT | Custom Plugin Setup
Step-by-step: add AutoEmails as a custom MCP plugin in ChatGPT so your GPT agent can build outreach, send tests and run campaigns through AutoEmails' bulk sen
What you get
ChatGPT can set up outreach end to end, write emails word-for-word, use merge variables, test-send to you and — after you say yes — go live through AutoEmails' sending infrastructure and allowances. Everything it builds appears in autoemails.com exactly as if you'd made it.
Setup
ChatGPT → Settings → Apps & Connectors → Advanced → turn on Developer mode.
Create → Add custom MCP server. Name: AutoEmails.
MCP server URL: https://xcfsmazseciunaoarmwx.supabase.co/functions/v1/mcp-server
Authentication: OAuth. If Dynamic Client Registration shows as unavailable, choose User-Defined OAuth Client and ask AutoEmails support for a client ID tied to ChatGPT's callback URL (leave secret empty, token auth: none).
Authorization URL: https://autoemails.com/mcp/authorize
Token URL: https://xcfsmazseciunaoarmwx.supabase.co/functions/v1/mcp-oauth/token
Scopes: mcp:read mcp:write mcp:admin
Enable PKCE (S256). Leave OIDC fields empty.
Create, sign in to AutoEmails and approve the workspace.
Permissions
mcp:read — read campaigns, leads, replies, meetings, reports and settings.
mcp:write — create drafts, edit copy, create variables, send tests to your own team.
mcp:admin — go live, add contacts, spend Decision Maker credits, save integration keys. Every one of these asks you to confirm in chat, and the workspace owner gets an email receipt with a 15-minute Stop link.
Changing permissions later (no need to uninstall)
Permissions are granted when you sign in. To add or change them, reconnect the account rather than uninstalling the plugin.
Open your assistant's plugin/connector settings → AutoEmails.
Under Connected accounts, open the … menu on your AutoEmails account and choose Disconnect.
Choose Connect another account, sign in to AutoEmails, pick the workspace and approve all permissions (read, draft, go-live).
Press Refresh tools so the newest actions load.
Ask your agent to call connection_status — it confirms which permissions it now has.
Safety model
Your agent can never send on its own. Anything real-world returns a plain summary first; it only happens after you reply yes, from the same signed-in owner or admin, within 15 minutes.
Live sends are refused unless the exact current copy has been test-sent in the last 24 hours. Changing a word means a new test.
A verified sending domain, the daily sending cap, sending hours and unsubscribes always apply. Opted-out contacts are never re-added.
First prompt to try
"Call connection_status, then set up an outreach campaign in AutoEmails for my company — a single email step targeting packaging companies in North West England. Ask me anything you need first."
About AutoEmails and Leo
AutoEmails is an AI email marketing platform built around Leo, an autonomous AI email marketing agent. Leo analyses your business, finds the right audience, writes and designs emails, launches campaigns and reports on replies, meetings, orders and revenue.
The platform covers three engines in one account: Outreach, which finds new companies or decision makers and emails them with personalised plain-text messages and follow-ups; Marketing, which sends designed HTML newsletters and campaigns to your own contacts; and Automations, which run triggered email journeys such as welcome series, abandoned cart recovery and re-engagement.
Leo works autonomously within guardrails. It can suggest and launch campaigns, resend to non-openers, expand targeting when a lead scan falls short and pause sending when deliverability signals such as bounce or spam-complaint rates rise. Every action is logged with an evidence trail so you can see what Leo did and why.
AutoEmails connects to Shopify, WooCommerce, WordPress, Calendly, Google Analytics, Google Search Console and custom e-commerce stores, so campaigns can be measured on real outcomes: replies and booked meetings for lead generation, and orders and revenue for e-commerce.
Pricing is capacity-based in British pounds, starting with a free plan. You can start free at autoemails.com without a credit card, let Leo scan your business and review the first campaign before anything is sent.
