Your Domain Can Be Used Against Your Customers
Email impersonation is one of the most common ways attackers target businesses. If SPF, DKIM or DMARC are missing or weak, criminals may be able to send convincing emails that appear to come from your company.
A strong email security setup helps protect your brand, reduce phishing risk, improve deliverability, and give recipients more confidence that your emails are legitimate.
