How to Send an Encrypted Email on iPhone/iPad: A Step-by-Step Guide

Sending an encrypted email on your iPhone or iPad is a way to keep your sensitive information secure. It’s like sending a locked safe through the mail instead of a postcard. With encryption, only the person with the key (in this case, the encryption password) can open and read your message. So, if you’re looking to send private information like passwords, financial details, or personal letters, encryption is the way to go.

After you send an encrypted email, you can rest easy knowing that your confidential information is protected. Only the intended recipient, who has the decryption key, can access and read your message. This ensures that prying eyes can’t intercept and read your private communications.


In the digital age, privacy is a hot button issue. With hacks, leaks, and breaches making headlines, it’s more important than ever to protect your personal information. That’s where encrypted emails come into play. Encryption is a process that scrambles your message, turning it into a code that can only be deciphered with the correct key. For iPhone and iPad users, sending an encrypted email might sound like a task for the tech-savvy, but it’s actually quite simple.

But why should you care about sending encrypted emails? Well, consider this – would you send a postcard with your bank account details on it? Probably not, right? Sending an unencrypted email is not much different. Anyone with the right tools can intercept and read your emails as they travel across the internet. By encrypting your emails, you’re putting up a strong defense against cyber threats. Whether you’re a business owner, a freelance professional, or just someone who values their privacy, learning how to send an encrypted email on your iPhone or iPad is a smart move.

Step by Step Tutorial: How to Send an Encrypted Email on iPhone or iPad

Before getting into the steps, it’s important to know that to send an encrypted email, both the sender and the recipient must have exchanged digital certificates. These certificates serve as the keys to unlock the encryption. Once you have exchanged certificates, you can follow these steps to send an encrypted email.

Step 1: Compose a New Email

Open your Mail app and start a new email by tapping the compose button.

When you’re sending an encrypted email, the process starts just like any other email. You’ll need to enter the recipient’s email address, a subject line, and the body of your message. Remember, the recipient’s email must be one that you have their encryption certificate for.

Step 2: Enable Encryption

Tap on the recipient’s name and select their encryption certificate to enable encryption for the email.

Once you’ve started composing your email, you’ll need to enable encryption. If you have the recipient’s certificate, their name should have a blue checkmark next to it. By tapping on their name, you’ll be able to select their certificate, which will encrypt the email.

Step 3: Send the Email

After composing your message and enabling encryption, tap send.

After you’ve composed your email and made sure encryption is enabled, all that’s left to do is send it. Once you hit the send button, your email will be securely encrypted and on its way to the recipient.


Enhanced PrivacyEncrypted emails offer a higher level of privacy as they can only be read by the intended recipient with the correct decryption key.
Protection Against Cyber ThreatsSending encrypted emails is a proactive measure against cyber threats like hacking and phishing, as encrypted emails are much harder to intercept and decipher.
Peace of MindKnowing that your sensitive information is securely sent can give you peace of mind, especially when dealing with important or confidential communications.


Requires Certificate ExchangeBoth the sender and recipient must have exchanged digital certificates beforehand, which can be a hassle if not already set up.
Limited to Email Clients that Support EncryptionNot all email clients support encryption, which can limit who you can send encrypted emails to.
Potential for Lost KeysIf you or your recipient lose the encryption certificate or forget the password, the encrypted email cannot be read, potentially leading to lost information.

Additional Information

Sending an encrypted email on your iPhone or iPad is a great way to ensure that your private information stays that way – private. It’s like putting your message in a digital vault that only the recipient can open. It’s important to remember, though, that both the sender and recipient need the correct encryption certificates for this to work. If you’re planning on sending encrypted emails regularly, it might be a good idea to keep a backup of your certificates just in case.

One more thing to keep in mind is that you should never share your encryption password over email or any other insecure method. If someone else gets hold of your certificate and password, they could potentially decrypt your messages. Always share passwords or certificates through a secure method, like in person or over a secure phone line.

Also, be aware that encrypted emails might not be foolproof. Technology is always advancing, and what is considered secure encryption today might not be tomorrow. So, always stay updated on the latest security measures and best practices.


  1. Compose a new email in the Mail app
  2. Enable encryption by selecting the recipient’s certificate
