Email Activity Deadline Reminder — Automated deadline alerts for Odoo

What is Email Activity Deadline Reminder?

Email Activity Deadline Reminder is a free Odoo module that automates email notifications for scheduled activity deadlines across your entire Odoo instance. Instead of relying on users to manually check their activity lists, the module sends recurring reminders at configurable intervals — every 5 minutes, hourly, or daily — starting from a defined date before the deadline. It works across Projects, Invoicing, CRM, and every Odoo model that supports scheduled activities, giving administrators centralized control over deadline accountability.

Flexible reminder frequency
Custom start dates
Inline activity editing
Zero-code setup

How Email Activity Deadline Reminder Solves Missed Deadline Problems

Problem
Zehntech Solution
Users forget scheduled activities spread across multiple Odoo modules
Automated email reminders surface every upcoming deadline directly in their inbox
No proactive notification before an activity becomes overdue
Configurable reminder start dates trigger alerts well before the deadline passes
One-size-fits-all reminder timing does not match varying task urgency
Three frequency options — 5-minute, hourly, or daily — match reminder intensity to deadline criticality
Editing a scheduled activity forces deletion and recreation of reminder rules
Editable scheduled activities let users modify details, deadlines, and intervals inline
Native Odoo has no built-in email reminder mechanism for activities
This module adds a dedicated reminder layer on top of standard Odoo activities via automated cron jobs
Reminder systems that only cover CRM miss project, invoice, and operational deadlines
Cross-module support ensures reminders work on Projects, Invoicing, and any activity-enabled model
Overdue activities accumulate silently without visibility or accountability
Automated activity deadline status view surfaces all passed-deadline items for admin review
Manual reminder setups do not scale across growing teams and increasing activity volume
System-wide cron-based configuration applies consistent reminder rules automatically to all users

Complete Activity Deadline Management Across All Odoo Modules

1

Automated Activity Deadline Status

View and manage all activities with full deadline tracking from a centralized admin interface. See which activities are approaching their deadline, currently due, or already overdue — and take corrective action directly.

Why it matters: Administrators gain instant organization-wide visibility into activity health without pulling reports from individual modules.

2

Customizable Reminder Frequency

Choose from three reminder intervals: every 5 minutes for urgent deadlines, hourly for standard tasks, or daily for longer-horizon activities. Match reminder intensity to deadline criticality without custom development.

Why it matters: A critical invoice due today needs more aggressive reminders than a project review due next week.

3

Configurable Reminder Start Dates

Define exactly when reminders begin for each activity. Set a start date days or hours before the deadline to give users advance notice, or configure reminders to begin on the due date itself for time-sensitive tasks.

Why it matters: Starting reminders too early creates noise; starting too late defeats the purpose. Configurable start dates let you find the right balance.

4

Editable Scheduled Activities

Modify task details, deadlines, reminder intervals, and assignees on existing scheduled activities without deleting and recreating the entire configuration. Changes propagate immediately through the reminder system.

Why it matters: Deadlines shift, responsibilities transfer, and priorities change — the reminder system must accommodate updates without administrative friction.

5

Automated Email Notifications via Cron

The system uses Odoo scheduled actions (cron jobs) to send reminder emails at the configured frequency. Notifications are delivered directly to the assigned user's inbox with full activity context included.

Why it matters: Cron-based delivery ensures reliability without manual intervention — reminders continue to fire even when administrators are not logged in.

6

Cross-Module Activity Support

Reminders work across every Odoo module that supports scheduled activities — including Projects, Invoicing, CRM, Sales, Purchase, HR, and custom modules using the activity mixin. One installation covers your entire Odoo instance.

Why it matters: Organizations do not operate in a single module. A unified reminder system prevents deadline fragmentation across different business functions.

7

Admin-Controlled Overdue Management

Activities that pass their deadline are surfaced in the deadline status view, where administrators can edit details, reassign ownership, or remove items that are no longer relevant.

Why it matters: Overdue activities represent organizational risk — surfacing them in a manageable interface prevents small delays from compounding into systemic problems.

8

No-Code Installation and Configuration

The module installs from the Odoo App Store and configures entirely through the standard admin interface. No server-side scripts, no custom development, and no external dependencies beyond standard Odoo modules.

Why it matters: Operations teams can deploy deadline reminders independently — without developer involvement or technical debt.
