You can connect Mailercloud to Perplexity by adding the official Mailercloud MCP server, https://mcp.mailercloud.com/mcp, as a custom connector and signing in with a Mailercloud API key. Perplexity can then combine web research with your own Mailercloud data.

How do I add Mailercloud to Perplexity?
In Mailercloud, go to Settings > API Keys, create a key named "Perplexity" and copy it.
In Perplexity, open the connectors or plugins area (in the sidebar or under Settings) and choose to add a custom connector.
Enter the name Mailercloud and the URL https://mcp.mailercloud.com/mcp, choose OAuth sign-in, and save.
On the Mailercloud sign-in page, paste your API key and click Connect.
Switch Mailercloud on for your search or chat, then ask: "Using Mailercloud, how did my last campaign do?"
Custom connectors may need a paid Perplexity plan.
What is Perplexity good for with Mailercloud?
Perplexity is strongest when you mix research with action. For example:
"Find the main shopping holidays in the UK next month, then compare them with when my past Mailercloud campaigns got the best open rates."
"What subject-line styles work best for e-commerce emails right now? Then suggest three for my next Mailercloud campaign."
"Check my Mailercloud sending domains and explain any problems with SPF, DKIM or DMARC."
Will Perplexity send emails or delete things without asking?
No. Mailercloud shows a preview first for anything that sends, schedules, deletes or blocks, and waits for you to reply yes.
Mailercloud isn't working in Perplexity. What should I check?
No option to add a custom connector: it may not be included in your Perplexity plan.
Perplexity answers from the web instead: make sure Mailercloud is switched on, and start with "Using Mailercloud, ...".
Sign-in fails: check the URL is exactly https://mcp.mailercloud.com/mcp and create a new API key if needed.
How do I disconnect Mailercloud from Perplexity?
Remove the connector in Perplexity, then delete the API key in Mailercloud under Settings > API Keys.
