What is Email deliverability?
Email deliverability is the ability of your emails to reach the recipient's inbox rather than the spam folder or being blocked. It depends on your domain reputation, authentication (SPF, DKIM, DMARC), sending volume, and content.
Even a perfect cold email fails if it never reaches the inbox. Deliverability is determined largely before you hit send: a warmed-up domain, proper authentication records, and reasonable sending volume from a healthy sender.
Common deliverability killers include sending too much too fast from a new domain, spammy content (all caps, money words, too many links), and high bounce rates from unverified email lists.
Verifying email addresses before sending is one of the simplest ways to protect deliverability. Weezly's leads database only exports verified emails, which keeps bounce rates low and reputation intact.
