How do I manually add encryption to my email account

On an iPhone, the only setting you can set is SSL (Secure Sockets Layer, a security technology). Open Settings > Mail > Accounts, select your account, tap Account, then SMTP, then the name of the “PRIMARY SERVER” and turn on “Use SSL”.

If this setting does not allow you to send emails, please contact your email provider.

Hi acoddens,

Thanks for posting in Apple Support Communities.

We understand you want to encrypt your email account. Which email account are you referring to? If this is for a third-party email account, you will need to reach out to your email service provider to enable the preferred security. For iCloud, there are different levels of encryption.

The security of your data in iCloud starts with the security of your Apple ID. All new Apple IDs require two-factor authentication to help protect you from fraudulent attempts to gain access to your account. Two-factor authentication is also required for many features across Apple’s ecosystem, including end-to-end encryption. 

Apple offers two options to encrypt and protect the data you store in iCloud:

* Standard data protection is the default setting for your account. Your iCloud data is encrypted, the encryption keys are secured in Apple data centers so we can help you with data recovery, and only certain data is end-to-end encrypted.

* Advanced Data Protection for iCloud is an optional setting that offers our highest level of cloud data security. If you choose to enable Advanced Data Protection, your trusted devices retain sole access to the encryption keys for the majority of your iCloud data, thereby protecting it using end-to-end encryption. Additional data protected includes iCloud Backup, Photos, Notes, and more.
