This guide walks through linking incoming emails directly to a client's referral file in Zoho CRM, ensuring communication records stay organized without cross-polluting client files.

This process applies to team members processing incoming email correspondence from third parties (such as solicitors) in Zoho Mail who need to link records to specific client files.

Why Associate Only with Referrals?

When receiving emails from third-party senders (such as solicitors) who represent multiple clients, associating an email with both the Contact and the Referral causes Zoho CRM to pull all email history from that contact into the client file. This inadvertently pulls unrelated client emails into the file.

Do not associate emails with Contacts or Leads. Always associate incoming emails exclusively with the specific client's Referral record.

Q: Why shouldn't I associate emails with Contacts?

A: Associating an incoming email with a contact (such as a solicitor) causes the CRM to pull all emails sent by that contact across multiple clients into that file, leading to unrelated client data showing up in the wrong record.

Q: Should I create or link Leads when processing incoming emails?

A: No. Ignore the Leads module entirely when linking incoming correspondence; only search and associate within the Referrals module.
