Insert a saved template

I need to insert the saved template titled Renewal Reminder into the reply thread with Priya Raj in procurement and include the quoted invoice and the three-line summary of late fees. Put the template into the body, confirm the invoice attachment is present, then send within this business day so procurement has time before Friday's payment run.

Before I drop the canned Renewal Reminder template into Priya Raj's thread, make the message easier to act on — pull the overdue amount and the next payment date to the top, bold the specific ask (confirm by Friday), and flag any missing attachments or conflicting invoice numbers that would slow approval.

I just opened Priya Raj's thread to reply with our saved Renewal Reminder and the details don't match the invoice — amounts differ and the attachment might be missing. I'm worried sending the wrong template will delay payment and damage my relationship with procurement. What is the best quick check and edit sequence to ensure the right template content, attachments, and a clear ask before I hit send?

Over the last month I have sent saved templates to procurement with wrong invoice numbers or amounts and had to follow up twice. This costs credibility and wastes time. What two habits should I change immediately — including a quick verification routine and a naming convention for templates — so the template always matches the thread's invoice before I send?
