Why is my signature not populated in the email messages that I send from Zoho CRM?
There are two ways to send emails.
You can send it from the Email tab (through Zoho Mail)
You can send it from within a specific record (leads, Contacts etc.)
When you send it through the Email tab, the signature that you had added in Zoho Mail, will be populated in your email. Whereas, when you compose an email from within a lead or contact, the Zoho CRM signature will be populated.
Note: Please ensure that you have the signature enabled for each mode of sending emails.
