SES uses internal anti-spam technologies to filter emails that contain poor content. In addition, it scans all emails containing attachments to check for viruses and other malicious content. It will not save your email content though.
During email transfer, SES will encrypt the content of your emails.
SES supports TLS 1.2, TLS 1.1, and TLS 1.0 for TLS connection.
By default, SES uses TLS. This means that SES will always try to establish a secure connection with the recipient's email server. If it cannot establish a secure connection, it will send the email in an unencrypted manner. You can change this option so that SES will only send emails when a secure connection can be established.
SES adopts many spam and virus protection measures. Tencent Cloud specifically maintains a blocked email address library and blocks emails from such addresses to help you filter malicious emails. SES scans every incoming email containing attachments for viruses. It provides you with various spam detection methods; for example, in addition to spam and virus scan results, it also provides DKIM and SPF check results.
SES uses internal content filtering technologies to detect spam. In addition, it also provides email quality scoring tools to help you check email content on your own. If it finds that an account is sending spam or malicious content, it will suspend the account's ability to send other emails.
Not being spam does not mean that the email will not go to spam folders. The email quality score is for reference only. Factors including the email content, domain reputation, open rate, and user complaints affect whether an email goes to spam folders. Different email service providers have different spam folder policies, over which we have no control. However, SES can guarantee the quality of sender IPs.
