What matters most

The easiest way to handle this is to keep the process simple and focus on the steps that usually trip people up.

• Use the company domain on every formal business email
• Set up authentication records before sending important mail at scale
• Protect the domain login and recovery details for the long term

What usually goes wrong

• Running invoices and quotes from a free mailbox
• Skipping email authentication setup
• Treating SSL as the only security layer that matters
