Why are some invoice emails sent to the CC field while others are sent as separate emails to the TO field, despite identical settings in TimeSolv?

This inconsistency occurs due to differences in Client Portal Access for the client contacts linked to the invoices:

• Invoices sent to the CC field: When the client contact does not have Client Portal Access, the invoice email is sent collectively to all recipients, including additional contacts listed in the CC field.
• Invoices sent as separate emails to the TO field: When the client contact has Client Portal Access, the invoice email is sent individually to the client contact, including a link to view the invoice in the portal.

This difference in email delivery behaviour depends on whether the associated client contact has portal access, even if all other settings are identical.

Example Details:

1. Invoice #123
   • Client Contact: test.timesolv@gmail.com
   • Portal Access: No
   • Email Behavior: Sent collectively to all recipients.
2. Invoice #321
   • Client Contact: test2.timesolv@gmail.com
   • Portal Access: Yes
   • Email Behavior: Sent separately to the client contact with a portal link.
