Cold Email Deliverability

Even the best-written cold email is worthless if it never reaches the inbox. Deliverability is determined by a complex combination of technical factors — SPF, DKIM, DMARC authentication records, domain age, and IP reputation — and behavioral signals gathered by email providers like Google and Microsoft. When too many recipients mark emails as spam, or when bounce rates are high, email providers reduce that sender's deliverability scores across the board. The most common causes of poor cold email deliverability are sending too many emails too quickly from a new domain, using domains and email addresses that have been previously associated with spam campaigns, using spammy language or excessive HTML in email content, and failing to set up proper authentication records. Email warm-up — the practice of gradually increasing sending volume from a new email address while generating positive engagement signals — is the primary technique for building deliverability before running high-volume campaigns. Outvid's video email approach provides an indirect deliverability advantage: because personalized video emails generate substantially higher engagement rates (opens, clicks, replies) than generic text emails, the positive behavioral signals they create help protect and improve sender reputation over time. Higher engagement signals to email providers that your messages are wanted, which improves future deliverability in a virtuous cycle.
