## About Mails.so with LuumenAI

Connect Mails.so and the agent can check whether an address is deliverable before you send to it. Validate a single address inline while you work, or submit a list and pull the results when the job finishes. Submitting a bulk job is a write, so it is previewed and held for your approval by default. Luumen authenticates with an API key.

## Example tools

Read-only (2 in total):

- `MAILS_SO_RETRIEVE_BATCH_RESULTS` — Retrieve results of a bulk validation job.
- `MAILS_SO_VALIDATE_SINGLE_EMAIL` — Validate a single email address.

Write and destructive (1 in total, approval required by default):

- `MAILS_SO_VALIDATE_BULK_EMAILS` — Validate multiple email addresses in bulk.
