Action
Get Subscriber Lists
Returns every list on the connected Acumbamail account with name, subscriber count, and configuration (double opt-in, custom fields). Use it to populate list-pickers at workflow setup or to inventory the account during audits.
Action

Sends a one-shot transactional email to a single recipient with subject, HTML body, and optional attachments. For sender-reputation hygiene, use separate Acumbamail sub-accounts/keys for transactional and marketing — mixing degrades deliverability over time.
