Sending e-mail 1 hour before a date field

Sending e-mail 1 hour before a date field

Hi,

We want to send a reminder to a lead which scheduled a demo with one of our accountmanagers. There is a date/time field in Zoho CRM which is called 'Calendly afspraak'. We've alreadt synced this field to Zoho Campaigns. How can we send an e-mail reminder to this lead 1 hour before his meeting?

So for example, the value of the field 'Calendly afspraak' = 1 jul 14:00 2024
