Improving Gmail inbox placement involves a holistic approach that combines technical configurations, content strategy, and audience engagement. Establishing a strong sender reputation through proper authentication (SPF, DKIM, DMARC), consistent list hygiene practices (removing unengaged subscribers, using double opt-in), and providing valuable, personalized content are key. While some suggest focusing solely on providing value regardless of tab placement, others recommend tactics like encouraging subscribers to add the sender to their contacts or even educating clients on disabling tabs. Avoiding spam triggers, optimizing email design, and continuously monitoring deliverability metrics are also essential to ensure emails reach the intended recipient's primary inbox.
