The inbox has to trust you before it sorts your email
Before any inbox feature sorts or sums up your email, Gmail's filters have to decide whether you look like someone worth trusting.

Google says Gmail uses machine learning, trained by what users do, to catch spam. Its filters look at the sending domain, whether bulk senders are authenticated, and what readers do. When someone marks a message as spam, the filters learn from it.
What Google asks of senders
- Authentication. Every sender sets up SPF or DKIM. Bulk senders also need DMARC.
- Easy unsubscribe. Bulk senders must offer one-click unsubscribe on marketing mail, plus a visible link in the email.
- Low spam reports. Google asks senders to keep reported spam rates low.
For a Kansas City shop writing past customers
- Send from your own domain, not a free mailbox.
- Keep one from-name customers know: you or the shop.
- Use a reply address a real person reads.
- Mail people who already paid you. Google says not to buy email addresses.
Setup handles the list side. I clean the list and fix the from-name and footer. Then I write in your voice, and you approve every email before it goes out. The inbox learns who you are, and so do your customers. The full path is on pricing.
