Email deliverability depends on the provider's infrastructure, IP reputation, authentication protocols, and server management. Businesses should choose mass email service providers that support SPF, DKIM, DMARC, dedicated IPs, and proactive reputation monitoring. Providers with optimized SMTP servers help emails land in the inbox rather than the spam folder.
