I'd like to be able to automate a few emails to my Customers using Zoho One but not sure the best way to approach this.

Purchase is made on website and info is added to CRM via an automation I've already built.

I'd like to send an email immediately when the new contact is created (basically at the time of sale).

I'd like to send a second email the next day at 9am.

I'd like to send a third email 2 days later at 9am.

I was able to get the first one sent easily with a workflow in CRM, but the workflow automations don't allow for an email to be triggered at a certain time from what I can tell, (only x hours/days since the trigger).

What's the best way to approach this using either CRM workflows, Zoho Campaigns, or something else?
