New Inbox Setup

Hello, i recently started working on getting all this setup but am a little concerned that i may be doing something wrong.

I purchased multiple domains specifically for outreach. For each domain, I created a separate Google Workspace account (one tenant per domain with 2-3 inboxes each) and followed Google’s full setup process, including domain verification and Gmail authentication. I configured DNS all at once in Cloudflare by setting Google’s MX records and adding SPF, DKIM, and DMARC (p=none).

After setup, I completed basic inbox reputation preparation (profile setup and signature) before connecting the inboxes to smartlead for warmup. I’m gradually ramping warmup sending volume over 3–4 weeks before starting real outreach.

Did i miss something or do something wrong, and if so is it too late to try to fix it?
