Use the Resend connector safely

Covers how to connect to Resend, confirm the account, pick the right tool for contacts, segments, templates and broadcasts, and get approval before anything changes or sends.

Use it when

You have just connected Resend and want to know what the assistant can do with it.
You are not sure whether a request needs a contact, segment or broadcast tool.
You want the assistant to ask before it creates, cancels or sends anything.

Tools it uses

create-contact
get-contact
add-contact-to-segment
create-contact-property
create-segment
create-topic
create-template
compose-template
duplicate-template
create-broadcast
compose-broadcast
get-broadcast
create-automation
get-automation
get-automation-runs
cancel-email
create-domain
create-domain-claim
create-api-key
create-webhook
connect-to-editor
disconnect-from-editor
create-contact-import
get-contact-import

Example

Before you change anything in Resend, check which account I'm connected to and tell me what you can access.

You're connected to the "Northwind Marketing" workspace with read and write access. Read-only lookups like contact and broadcast status run freely. Anything that creates a segment, sends a broadcast or cancels an email will show you the exact change first and wait for your yes.

Build and check Resend audience segments with AI

Creates Resend segments and topics, adds contacts to them and checks who a segment would reach. Asks for approval before changing any membership and never sends a message.

Use it when

You want a segment of customers who bought in the last 90 days.
You need a topic so people can opt in to product news.
You want to check that a segment excludes unsubscribed contacts before you target it.

Tools it uses

get-contact
create-segment
create-topic
add-contact-to-segment

Example

Make a segment called churn-risk for contacts who have not opened an email in 90 days, and check it doesn't include unsubscribed people.

I drafted the rule: contacts with no opens in 90 days and not unsubscribed. Your account has no existing churn-risk segment, so I can create it. Before I add anyone, please confirm the rule, then I'll add contacts in batches and spot-check a sample of 25 against their status. Nothing will be sent.

Audit your Resend automations with AI

Reviews your Resend automations and their recent runs to find failing, stalled or unexpected behaviour, then reports a prioritised list of what to fix. It never changes an automation without asking.

Use it when

A lifecycle email flow seems to have stopped sending
You want a health check of every automation before a launch
A contact got an email they should not have received

Tools it uses

get-automation
get-automation-runs
get-contact
get-broadcast

Example

Audit my Resend automations and tell me which ones are broken.

I reviewed 6 automations over the last 30 days. Two need attention. The 'Welcome series' has run 0 times because its trigger segment is empty, so it cannot fire. The 'Trial reminder' ran 41 times but 18 contacts re-entered it, which suggests a trigger that fires on every profile update. I have not changed anything; tell me which fix you want to apply.

Prepare a Resend broadcast campaign with AI

Builds a marketing broadcast from a template or draft, checks the audience and content, and stages it. It asks for your explicit approval before anything is sent.

Use it when

You are preparing a newsletter or announcement for a segment
You want a campaign checked for placeholders, dead links and wrong dates before it goes out
You want to stage a broadcast now and send it later

Tools it uses

compose-template
duplicate-template
get-broadcast
create-broadcast
compose-broadcast
get-contact

Example

Prepare the spring launch broadcast for the 'Product updates' segment from our newsletter template and check it before I send.

Campaign 'Spring launch' is staged as a draft for the 'Product updates' segment, sender from your verified domain. I found one blocking issue: the body still contains the placeholder '{{discount_code}}' and the link points to staging. Nothing has been sent. Shall I fix the link and check 3 sample contacts before we schedule the send?

Import and clean Resend contacts with AI

Imports a contact list into Resend and checks addresses, duplicates and opt-out status before writing anything. It asks for your approval before every change.

Use it when

You have a newsletter signup export to bring into Resend
Contacts show up twice because of capitalisation differences
You need a new custom property before importing a CSV

Tools it uses

get-contact
create-contact-property
create-contact-import
get-contact-import

Example

Import this CSV of 1,200 signups into Resend, skip anyone who unsubscribed, and tell me how many rows were malformed.

I checked the file first: 1,200 rows, 1,148 valid, 37 malformed addresses and 15 duplicates after lower-casing. Your file marks 52 people as unsubscribed, and I will not import them as subscribed. Shall I create the new 'plan' property and run the import for the 1,148 valid rows?

How Resend skills work

Connect Resend
The Resend MCP server gives the agent its tools.
Ask in plain words
“Make a segment called churn-risk for contacts who have not opened an email in 90 days, and check it doesn't include unsubscribed people.” Each SKILL.md says when it applies, so only the one that fits is loaded.
Approve any change
The agent calls the tools in order, checks its work, and shows you any change before it makes it.

Resend skills FAQ

What is a Resend agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Resend skill describes one job, which Resend tools to use in which order, what to check first and when to stop and ask you.

Do the Resend skills change anything on their own?

1 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Resend.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Resend; elsewhere you copy the folders into your project or skills directory.

Do I need the Resend MCP server too?

Yes. The skills tell the agent how to do the work; the Resend MCP server gives it the tools to do it. The Resend MCP setup guide covers every client.
