Pay attention to password security

Someone else may know your email account password. This gives them access to your account and all its contents, including other people’s emails. This gives them room to conduct suspicious activities on your behalf.

Check complaint and spam folders

If you’re receiving a large number of complaints about your email delivery, it may be because many recipients are receiving email from an unreliable sender using your address.

Consequences of sending mail using invalid source email addresses

If your emails are blocked as spam or bounced, it damages your brand reputation. Recipients may think you need to care more about them to send emails from a legitimate source. This can affect their perception of your business, leading to lost sales and referrals.

Risk of spammers and phishers

When messages are sent from malicious sources, the original sender often puts themselves at risk for spam filters. If the filter deems their email to be spam, it may be sent directly to the recipient’s spam folder or blocked entirely. In addition to inconvenience for recipients, it can have a serious impact on your business if you consistently send a large amount of spam.

Legal consequences

Failing to verify the validity of an email address can have legal consequences. For example, if you send a large number of marketing messages and a recipient claims to have suffered a loss as a result of receiving your message, you could be held responsible for any losses they suffered.
