# Connect Mailjet and SendGrid

When **New Contact** fires in [Mailjet](https://apiant.ai/connections/mailjet), your agent runs **Create or update contact** in [SendGrid](https://apiant.ai/connections/sendgrid), or **New bounce** in SendGrid to **Remove Contact from List** in Mailjet. Describe the whole flow and it is built, tested on every scenario and kept running.

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want Mailjet and SendGrid to do together?

Give your AI client this address.

`https://mcp.apiant.ai`

One 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

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Cursor

Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Zed

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### 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)](https://apiant.ai/docs/mcp)

### 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.

If you run Mailjet and SendGrid side by side, this connection keeps contacts, lists and suppressions from drifting apart. New contacts and lists created in Mailjet can be mirrored into SendGrid marketing contacts, and bounces or unsubscribes recorded in SendGrid can be reflected back on the Mailjet side so you stop mailing addresses that already went bad.

Questions

## Mailjet and SendGrid, answered

###

### Can I check whether a contact already exists in SendGrid before creating it?

Yes. The agent can use Get contact by email in SendGrid as a lookup step, and only run Create or update contact when nothing comes back, so you don't overwrite details on an existing marketing contact.

###

### What happens on the Mailjet side when SendGrid reports a bounce or an unsubscribe?

A new bounce or a new global suppression in SendGrid can trigger Remove Contact from List or Update Contact in Mailjet, so the address is taken off the list or marked as excluded from campaigns. The agent tests every scenario before it runs on live data.

###

### What can start an automation from Mailjet?

Any of Mailjet's 3 triggers in the catalog, including New Contact, New Contact in List and New Contact List. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in SendGrid when something happens in Mailjet?

Any of SendGrid's 10 actions, including Create list, Create or update recipient, Get contact by email and Create custom field. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from SendGrid to Mailjet?

Yes. When something happens in SendGrid, your agent can act in Mailjet too. This page covers both directions: SendGrid's triggers and Mailjet's actions are listed here as well.

###

### Do I have to build a connector for Mailjet or SendGrid?

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 Mailjet and SendGrid 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.
