Gmail Business Email Campaign Setup

I need my new Google Workspace (Gmail bisnis) ready for one purpose: sending promotional messages that convert small- and medium-business owners into paying customers.

Here is what I am looking for you to handle from start to finish:

• Configure a professional Gmail bisnis account under my chosen domain, including SPF, DKIM, and DMARC so every message lands in the inbox.
• Build a clean, permission-based email list targeting pemilik usaha kecil dan menengah. You may source, verify, and segment the contacts so bounce rates stay low and relevance stays high.
• Create at least one reusable promotional template inside Gmail (or a compatible add-on such as GMass, Yet Another Mail Merge, etc.) and show me exactly how to launch a campaign on my own afterward.

The job is complete when the account sends a test campaign without hitting spam folders, the contact list is delivered in a spreadsheet ready for import, and I understand the step-by-step process.
