Summary
To avoid Gmail rate limits when sending essential communications to a large, infrequently mailed audience, a holistic strategy is crucial. Experts, email marketers, and documentation all agree on the importance of sender reputation, achieved through authenticated email (SPF, DKIM, DMARC), low spam rates, easy unsubscribes, and good list hygiene (removing inactive users and handling bounces). Engagement is key, requiring relevant, high-quality content, segmented audiences, and controlled sending frequency. Additionally, alternative communication channels should be considered, and Google Postmaster Tools should be used for continuous monitoring. A well-planned IP warmup is recommended, along with adherence to CAN-SPAM regulations and a strategy for slowly increasing volume.
Key findings

Expert view
Expert from Email Geeks suggests re-evaluating the strategy of gathering email addresses without regular mailing, and if a monthly newsletter doesn't bring value, it might not be worth sending at all.
