Email issues, such as failed deliveries or incorrect configurations, can disrupt communication. Start by verifying the email server settings (SMTP, IMAP, or POP3) provided by your hosting provider. Ensure your DNS records, like MX records, are properly configured to direct email traffic. Check for any email-blocking blacklists or issues with your domain’s reputation. If you’re having trouble sending emails, check your email sending limits, as some hosting providers impose limits on outbound email volume to prevent spam. Lastly, ensure your hosting provider has up-to-date security protocols, such as SPF and DKIM, to protect against phishing and spoofing attacks.
