Tasks drive your sales and operations. But without timely reminders, even the most important follow‑ups can slip through the cracks. Zoho CRM offers multiple ways to customize task reminders—from simple email alerts to complex, condition‑based notifications. This guide walks you through standard reminders, workflow‑driven alerts, and advanced Deluge customizations. Technofog helps you design and implement a reminder system that keeps your team on track.
Why Customize Task Reminders?
Never Miss a Deadline
Ensure critical follow‑ups, contract renewals, and service calls happen on time.
Personalize Notifications
Send reminders via email, SMS, or in‑app pop‑ups. Tailor messages with task details and links.
Conditional Alerts
Send reminders only when certain conditions are met (e.g., task priority = high, deal stage = negotiation).
3 Ways to Customize Task Reminders in Zoho CRM
1. Standard Task Settings
Every task has a built‑in reminder option. When creating a task, simply set a reminder date/time. Zoho will send an email notification to the assignee.
- Works for individual tasks
- Email notification only
- Simple and quick
2. Workflow Rules
Create workflows that send custom reminders based on task fields (e.g., due date, priority). You can use email templates and even SMS.
- Conditional reminders
- Send to multiple recipients
- Custom email/SMS content
3. Deluge Custom Functions
For ultimate flexibility, use Deluge to send reminders via API, push notifications, or integrate with external systems like Slack.
- Complex logic (e.g., remind 3 days before, then 1 day, then day of)
- Integrate with external calendars
- Log reminder history in CRM
Step‑by‑Step: Custom Reminders with Workflow
Go to Setup → Automation → Workflow Rules
Create a new workflow rule. Choose "Task" as the module. Set rule name and description.
Define the Trigger
Select "Time Based" and set the trigger condition (e.g., "1 hour before due date"). You can also use "Record Action" for on‑create/update.
Add Conditions (Optional)
Filter which tasks should trigger reminders. For example: Priority equals "High" OR Subject contains "Contract".
Add an Instant Action
Choose "Email" or "SMS". Use placeholders like ${Tasks.Subject}, ${Tasks.Due_Date}, ${Tasks.Owner.Email} to personalize the message.
Activate & Test
Activate the workflow and test with a sample task. Adjust timing and content as needed.
Advanced: Deluge Custom Function for Multi‑Step Reminders
// Deluge function to send reminders 3 days, 1 day, and on due date
// Schedule this function to run daily via a workflow or scheduler.
taskRecords = zoho.crm.getRecords("Tasks", {"Due_Date": {"between": [today, today.addDays(3)]}});
for each task in taskRecords
{
daysUntilDue = task.get("Due_Date").diffDays(today);
if(daysUntilDue == 3 && task.get("Reminder_Sent_Day3") != "Yes")
{
sendReminderEmail(task, "3 days remaining");
zoho.crm.updateRecord("Tasks", task.get("id"), {"Reminder_Sent_Day3": "Yes"});
}
else if(daysUntilDue == 1 && task.get("Reminder_Sent_Day1") != "Yes")
{
sendReminderEmail(task, "1 day remaining");
zoho.crm.updateRecord("Tasks", task.get("id"), {"Reminder_Sent_Day1": "Yes"});
}
else if(daysUntilDue == 0 && task.get("Reminder_Sent_Due") != "Yes")
{
sendReminderEmail(task, "Due today!");
zoho.crm.updateRecord("Tasks", task.get("id"), {"Reminder_Sent_Due": "Yes"});
}
}
function sendReminderEmail(task, message)
{
subject = "Task Reminder: " + task.get("Subject");
body = "Hello " + task.get("Owner.Name") + ",\n\n" +
"This is a reminder that the following task is " + message + ":\n\n" +
"Task: " + task.get("Subject") + "\n" +
"Due Date: " + task.get("Due_Date") + "\n" +
"Related To: " + task.get("What_Id") + "\n\n" +
"Please complete it on time.\n\n" +
"Best regards,\nZoho CRM";
sendmail
[
to : task.get("Owner.Email")
subject : subject
message : body
];
}

Best Practices for Task Reminders
Set Multiple Reminders
Send a reminder 3 days before, then 1 day before, and finally on the due date to ensure action.
Use Personalized Content
Include task details, related record links, and clear next steps to reduce confusion.
Track Reminder Delivery
