Email Deliverability

refers to the ability of an email message to reach the intended recipient's primary inbox rather than being filtered into spam folders, promotions tabs, or rejected outright by email service providers. Achieving high deliverability requires maintaining a strong sender reputation — built through consistent sending practices, clean list hygiene, low complaint rates, and proper technical authentication setup including SPF, DKIM, and DMARC records. ConnectGain's email channel actively monitors sender reputation metrics, automatically suppresses hard-bounced addresses and unsubscribed contacts, provides guidance on email content best practices that minimize spam filter triggers, and offers dedicated IP address options for enterprise senders who need to build reputation independently of shared infrastructure.
