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.
Operations
-
Keep campaigns and files in tidy folders
Ask the agent to move old Mailchimp campaigns into a quarterly folder, upload the new logo and header images, and list what is sitting in the file manager.
-
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.
-
Clean up stale connectors in bulk
Pull the full list of Nylas connectors, pick the ones nobody uses, and update or remove them together instead of one at a time.
Support
-
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.
-
Fix a contact record after a complaint
When someone writes in asking to change their details or stop receiving mail, look up their ElasticEmail contact and update or remove it while they are still on the line.
-
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.
Marketing
-
Draft the launch broadcast before it sends
Ask for a new Resend broadcast with the announcement copy, then have the subject line, preview text, and audience adjusted in plain language. Review the draft in Resend before anything goes out.
-
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.
IT
-
Set up and maintain sending domains
Add a new sending domain, update its details when DNS changes, and retire old domains without opening Flexmail settings.
-
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.

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. API key and App credentials mean an admin pastes them once, with nothing to register.

FAQ
Frequently asked questions
How many Email connectors does Elaichi have?
10+ 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 or any MCP client connects to that same address with OAuth, while the Elaichi Agent reaches the same tools inside the app. 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. 3 of the Email connectors use Elaichi's hosted sign-in, with nothing to register. 8 connect with an API key or app credentials that an admin pastes once, with no app to register. 1 asks 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 left out of the model's tool list and cannot be called. Read-only access to a Email connector is a matter of allowing the reads and leaving the writes out.
