It may sit under another category, or not be in the catalog yet — any documented API can become a connector.
In practice
What teams do with Email connectors
Drawn from the connector pages in this category, so every line describes something one of these connectors actually does.
Support
-
Find the email a customer is asking about
When a customer replies to a promotion, ask which Mailchimp campaign went out that day, what it said and when it was sent, so the answer is right the first time.
-
Find every email about one customer issue
Search the shared support mailbox for a customer's address or a ticket number and read the full history in one place. Screenshots and log files sent by the customer can be downloaded without hunting through the inbox.
-
Find out why a customer's email bounced
Ask which messages to a customer bounced, read the bounce details, and reactivate the address once the problem is fixed, all from the chat you are already in.
Operations
-
Approve or clear access requests
See who has asked for more SendGrid access, approve the ones that make sense, and remove the ones that do not, without logging in to hunt for the queue.
-
Tidy up topics and preferences
See every Resend contact topic your audience can opt in or out of, rename the ones that no longer match how you describe your emails, and keep the preference center current.
-
Clear the inbox of newsletters and notices
Label or trash the automated notices, subscriptions, and calendar noise in one pass so the messages that need a person stay visible.
Marketing
-
Check deliverability by mailbox provider
Pull Mailtrap stats broken down by email service provider and by date to see whether Gmail or Outlook deliveries dipped last week and whether a campaign was affected.
-
Send a one-off email without opening Amply
Ask for a message to go out through Amply to a customer or a test inbox, with the subject and body you dictate, and confirm it was accepted for delivery.
-
Draft next week's newsletter from a brief
Describe the offer and the audience, and the agent creates the Mailchimp campaign with the subject line and preview text filled in. Ask for a test send to yourself before anyone else sees it.
IT
-
Onboard a new teammate in minutes
Invite a new hire to SendGrid and give them the same permissions as the rest of their team, all from one request. Check the pending invitation later and clear it if they never accepted.
-
Check mailbox storage across the organization
See how much storage each Zoho Mail account is using, spot the accounts close to their limit, and adjust storage allocations before anyone stops receiving mail.
-
Review webhooks after an incident
List every Mailtrap webhook, check which endpoint each one points to, and update the ones that moved during a migration so bounce and delivery events keep flowing.

Every Email connector, by depth
Tool counts are what the connector exposes today; the split is what those tools do.
Hosted sign-in takes a partnership with each vendor, and more are in progress. Until one lands, Your own app means the connector works today — you register an OAuth app once and connect.
FAQ
Frequently asked questions
How many Email connectors does Elaichi have?
5+ Email connectors are in the catalog today, and the list grows as connectors are added. Each one arrives as a set of MCP tools an agent can call through https://api.elaichi.ai/mcp.
Can Claude, ChatGPT and Cursor all use Email connectors?
Yes. Elaichi exposes one organization-wide endpoint, https://api.elaichi.ai/mcp, and Claude, ChatGPT, Cursor, any MCP client and the Elaichi Agent all connect to that same address with OAuth. Connecting a Email account once makes it reachable from every one of them.
Do Email connectors work with Gemini, Codex, Claude Code or other MCP clients?
Yes. Email connectors are reached over the same MCP endpoint every client uses, so anything that speaks MCP can call them — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor and the Elaichi Agent. There is no per-client setup beyond pointing the client at https://api.elaichi.ai/mcp.
Do Email connectors need me to bring my own OAuth app?
Most do not. 8 of the Email connectors use Elaichi's hosted sign-in, with nothing to register. The other 1 ask you to bring your own OAuth app: you register it once with the vendor and connect. Hosted sign-in for those is in progress, a vendor partnership at a time, and when one lands the only thing that changes is that the registration step goes away. Each connector's page says which it is before you start.
Can I stop an agent from writing to Email tools?
Yes. Tool restrictions apply at role and individual level, and a restricted tool is never advertised to the model, so it cannot be called or guessed at from the tool list. Read-only access to a Email connector is a matter of allowing the reads and leaving the writes out.
