There are several steps you can take to make your email safer:

1. Use a secure email service: Choose an email service that uses secure communication protocols, such as Transport Layer Security (TLS), to encrypt your email communication.
2. Use strong passwords: Use strong, unique passwords for your email account and do not share them with anyone. Consider using a password manager to help you generate and manage strong passwords.
3. Enable two-factor authentication: Two-factor authentication adds an additional layer of security to your email account by requiring you to provide a second form of authentication, such as a code sent to your phone, in addition to your password.
4. Be cautious with links and attachments: Do not click on links or download attachments from unknown sources, as these could contain malware or lead to phishing attacks.
5. Use email authentication protocols: Implement email authentication protocols, such as DMARC, DKIM, and SPF, to help protect against spam, phishing, and spoofing.
6. Keep your software and devices up to date: Make sure to keep your email client software and devices up to date with the latest security patches and updates.

By following these steps, you can help to improve the security of your email and protect yourself against various types of threats.

DMARC, DKIM and SPF explained

DMARC, DKIM, and SPF are all email authentication protocols that help to protect against various types of threats on the internet, including spam, phishing, and spoofing. Here is a brief overview of each protocol and why you should consider implementing them:

1. DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC is an email authentication protocol that helps to protect against spam and phishing attacks by verifying that messages are sent from an authorized domain. By implementing DMARC, you can help to ensure that only messages sent from authorized domains are delivered to your users, and you can also receive reports on any messages that fail DMARC evaluation.
2. DKIM (DomainKeys Identified Mail): DKIM is an email authentication protocol that uses digital signatures to verify the authenticity and integrity of messages. By implementing DKIM, you can help to ensure that your messages are not modified during transit and that they are sent from an authorized domain.
3. SPF (Sender Policy Framework): SPF is an email authentication protocol that helps to prevent spoofing by verifying that messages are sent from an authorized IP address. By implementing SPF, you can help to ensure that only messages sent from authorized IP addresses are delivered to your users.

To implement these protocols, you will need to modify the DNS records for your domain and configure your email server to use them. You may also need to work with your email provider or IT department to ensure that the protocols are properly implemented.

Overall, implementing DMARC, DKIM, and SPF can help to improve the security of your email communication and protect your domain and email against various types of threats.
