I’m looking to extend the native Marketing Automation app in Odoo so it automatically picks 30 new leads every day, fires off a predefined email to those contacts, and then flags each one as “sent” so they aren’t selected again. Key behaviour I need: • At a choosen date range and time of day (server time) the system should randomly choose exactly thirty leads whose status is “New”. • It must dispatch a single template email to that group immediately, log the activity on each record, and update a Boolean/Stage field to prevent re-use. • The job has to run hands-free once deployed; I only want to tweak the template or change the daily run time from the Odoo UI, not in code. I’m on the latest Odoo 18 Enterprise with standard Marketing Automation installed. Use Odoo’s scheduler (cron) and any clean Python/ORM code you like, but please keep it fully upgrade-safe and module-based so I can drop it into staging, test, then push to production. Deliverable is a ready-to-install custom module plus a quick read-me that tells me where to place the template and how to enable/disable the cron job. If you have handled similar batch-email tasks in Odoo before, let me know—speed of delivery matters.
