What do you want CustomGPT.ai and Mailrelay to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.
Set it up in your client

Run this in the directory you want to work in.

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.
Setup guide (opens in a new tab)Codex and the ChatGPT desktop app
Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.
Setup guide (opens in a new tab)Any other MCP client
Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.
Setup guide (opens in a new tab)CustomGPT.ai holds the conversations people have with your chatbot, and Mailrelay holds the subscriber lists you email. Joining them means a chat that produces a contact can land in Mailrelay as a subscriber, and a new Mailrelay subscriber can be matched to the right CustomGPT.ai agent or conversation. Describe what you want and the agent builds and tests it.

Questions
CustomGPT.ai and Mailrelay, answered
How do contacts from a chatbot conversation reach Mailrelay?
The New Conversation trigger in CustomGPT.ai can be followed by Export Conversation Leads, then Find subscribers by criteria in Mailrelay to check whether the person is already known. From there the agent either uses Add subscriber or Update subscriber, and it tests every scenario before it runs.
Can a new Mailrelay subscriber be handled inside CustomGPT.ai?
Yes. The New subscriber trigger in Mailrelay can lead to Create Conversation or Find Agent in CustomGPT.ai, so a fresh signup is matched to the right agent or given a conversation to start from.
What can start an automation from CustomGPT.ai?
Any of CustomGPT.ai's 1 trigger in the catalog, including New Conversation. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mailrelay when something happens in CustomGPT.ai?
Any of Mailrelay's 11 actions, including Add campaign, Add group, Update subscriber and Add subscriber. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mailrelay to CustomGPT.ai?
Yes. When something happens in Mailrelay, your agent can act in CustomGPT.ai too. This page covers both directions: Mailrelay's triggers and CustomGPT.ai's actions are listed here as well.
Do I have to build a connector for CustomGPT.ai or Mailrelay?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use CustomGPT.ai and Mailrelay without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
