Email Deliverability
Email deliverability is the discipline of ensuring marketing and sales emails reach prospect inboxes — managing sender reputation, authentication standards (SPF, DKIM, DMARC), content quality, and engagement signals that affect inbox-vs-spam routing decisions.
Why This Matters
Deliverability has become a critical competency for B2B email-driven outreach. ISPs (Gmail, Outlook, Yahoo) use sophisticated algorithms to determine inbox-vs-spam routing, considering: sender reputation (historical complaint rates, bounce rates, engagement rates), authentication (SPF, DKIM, DMARC standards), content quality (avoiding spam-trigger keywords and patterns), engagement signals (opens, clicks, replies vs. deletes and complaints), and list quality (engaged vs. dormant subscribers). Modern best practices: domain warming for new sending domains, list hygiene (regular bounce removal and engagement-based suppression), authentication standards implementation, and engagement-driven sending (focus on engaged segments while suppressing dormant ones).
Frequently Asked Questions
Frequently Asked Questions
What hurts B2B email deliverability most?
Sending to dormant or invalid email addresses (high bounce/complaint rates damage sender reputation), missing authentication standards (SPF/DKIM/DMARC failures trigger spam routing), spam-trigger content patterns (certain keywords, formatting, and link patterns), and overly aggressive sending volume from cold domains.
How can B2B teams improve email deliverability?
Implement SPF/DKIM/DMARC authentication properly, warm new sending domains gradually, maintain list hygiene through regular bounce removal and engagement-based suppression, focus content on engagement-driving messages, and segment lists to send only to engaged subscribers when possible.
