Send out follow-up email in the same thread (threaded conversations in individual emails) from Zoho CRM

Hi, I'm new to Zoho. I'm trying to send individual emails to my leads one by one. And I'll send out follow up email if I don't hear back from them later. However, instead of sending a new email, I want to reply in the same email thread so that the recipients know that we're following through the same topic. Can I do it in Zoho? Or this can only be done in mail client like apple Mail?

Thank you!
