I am facing issue with email subject, because client does not understand about email before opening the email content or email attached invoice. So it will be good if we can change or customize different email subject for every alternate invoice. Please assist me in the same.
– How to change or customize different email subject for every alternate invoice.
You cannot customize the subject line per-email from the system, however in the invoice creation page (https://app.invoiceninja.com/invoices/create) you can click the link “View as recipient” and copy that link to email your client directly in a regular email, if that makes it easier for them.
