Email deliverability is the ability of an email to successfully reach the recipientâs inbox. DNS issues can cause several problems, such as:
Authentication Failures: If your DNS settings are incorrect, email authentication methods like SPF, DKIM, and DMARC can fail. This can make your emails look like spam or phishing attempts. IP Blacklisting: Poor DNS configurations can contribute to your IP address being blacklisted, causing ISPs to block your emails. Bounced Emails: Incorrect DNS records can result in undeliverable emails, leading to high bounce rates and damaging your sender reputation.
