Gmail Customer Inquiry Auto-Responder Setup

I need my Gmail account to send polished, on-brand replies to every new customer inquiry without me lifting a finger. The workflow is straightforward: when a message lands in my inbox and matches set criteria (e.g., comes through our website form or includes certain keywords), Gmail should fire back a personalised acknowledgment that thanks the sender, provides basic information about our services, and lets them know when a human will follow up.

Here’s what matters to me:
• The response must pull the customer’s name automatically and feel conversational, not robotic.
• Messages must be threaded correctly so further dialogue stays tidy.
• I should be able to tweak the template text easily later, so please use native Gmail tools—Filters, Templates (formerly Canned Responses), or, if needed, a lightweight Google Apps Script. No third-party platforms that add monthly fees.
• Everything must remain compliant with Gmail’s sending limits and best practices.

Once configured, give me a brief screen-share walk-through or a concise PDF so I understand how to adjust keywords, turn the rule on/off, and edit the template.

That’s it—clean, reliable automation that keeps our first-touch response time at zero minutes.
