# Assign Warmup Tag

> Put a tag on an email account.

Requires an API key with the `write` scope.

Warmup tags group accounts in the warmup pool. They do not change sending. Repeating the call is safe: a tag already on the account stays as it is.

## Path Parameters

<ParamField path="account_id" type="string" required>The email account id.</ParamField>
<ParamField path="tag_id" type="string" required>The tag id.</ParamField>

## Response

<ResponseField name="data" type="object">
  <Expandable title="data">
    <ResponseField name="accountId" type="string">The email account.</ResponseField>
    <ResponseField name="tagId" type="string">The tag.</ResponseField>
    <ResponseField name="assigned" type="boolean">`true`.</ResponseField>
  </Expandable>
</ResponseField>

## Rate Limit

- **120 requests per minute, shared by every `write` call in your workspace.** Fixed 60-second window.
- Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` (unix epoch seconds) and `X-RateLimit-Bucket` (`write`).
- A `429` response includes a `Retry-After` header (seconds until the bucket resets).
