Perplexity

Manage email templates locally.

You use the `list_templates` tool to see all existing UniOne email templates. This lets you check if a specific marketing campaign already has its own reusable template. Need something new? You run `set_template` to create or update a template right from your local environment, so your team stays on one page.

Send live transactional emails.

When you need to send an email immediately—like a password reset or confirmation—you call `send_email`. This sends the actual message content directly, bypassing template logic entirely. It's perfect for quick API calls. You don't have to leave your dev server; just run the tool and get that transactional email out.

Track suppressed emails.

The `list_suppression` tool shows you which addresses UniOne has flagged as suppressed. This is critical for keeping your sender reputation clean. Before running any bulk campaign, check this list. You also use `set_suppression` to manually add specific emails if necessary.
