Email Deliverability
The percentage of sent emails that actually land in the recipient inbox (vs spam or quarantine). Healthy SMB deliverability is above 95%. Common destroyers: poor sender reputation, missing SPF/DKIM/DMARC records, sending from a domain too new, no warmup period for cold-email campaigns. AI follow-up agents do not fix deliverability - dedicated infrastructure (Smartlead, Instantly) plus 30-day domain warmup does.
