I have more than 5 years of experience designing, developing, maintaining, customizing ZOHO CRM for my clients based in Mumbai.
Cleaning up the data (normally in CSV/ excel file) is an inherent part of the requirements for the work.
Workflow routines have been automated to trigger a task/ reminder in the lead pipeline, send an email or trigger a message in SLACK or any messaging.
This can also be linked to Zoho Campaigns.
At present, I am working on ZOHO one set up for my client.
