Gmail bulk sender basics
Gmail expects a competent baseline from bulk senders: stable authentication, list hygiene, clear unsubscribe handling and consistent traffic quality.
Technical baseline
- SPF, DKIM and DMARC properly configured
- PTR and HELO that make sense
- Stable sending identity and domain structure
Audience hygiene
Bulk sending quality shows up quickly. Poor acquisition, stale lists and ignoring user intent are among the fastest ways to lose Gmail trust.
Unsubscribe and user control
Make it easy for recipients to stop mail they no longer want. Friction here often turns into complaints, which are far more damaging than unsubscribes.
Consistency beats bursts
Predictable traffic patterns are easier for mailbox providers to trust than sporadic spikes followed by silence.
