Quick Answer

Email security comes down to layers. Use long, unique passwords stored in a password manager rather than reused or memorable ones. Turn on multi-factor authentication so a stolen password alone doesn't grant access. Run a proxy or VPN on untrusted networks to keep IP and session data out of an attacker's view. Then authenticate the domain itself: SPF lists the IPs allowed to send from your domain, DKIM signs each message with a private key the recipient verifies against a public key in DNS, and DMARC tells receivers what to do when SPF or DKIM fails (none, quarantine, or reject) and sends back reports so you can see who's spoofing you. Skipping any one of these leaves a gap. SPF without DMARC gives no enforcement signal. DKIM without alignment passes attacker mail. Strong passwords without authentication still let spoofed mail reach your customers. Run all of them together.

![Secure Emails](https://media.mailhop.org/duocircle/images/2024/04/sendgrid-alternative-4218.jpg) 

Email communications are sensitive and prone to exploits, as many details and attachments are exchanged. [Threat actors look for vulnerabilities](https://www.techtarget.com/searchsecurity/feature/10-of-the-biggest-zero-day-attacks-of-2023) in an **email ecosystem** and develop strategies to compromise them to steal, alter, and intercept financial details, login credentials, medical information, etc.

**To prevent this** from happening, you need to shrink all the [email security gaps](https://today.ucsd.edu/story/forwarding%5Fbased%5Fspoofing) and be in charge of the overall [cybersecurity](/). Here’s what you should focus on-

## Use Strong Passwords

Weaker and easy-to-guess passwords are a big no-no, especially for your **official email accounts**. It’s suggested that you use an [open source password manager](http://psono.com/) to store and manage passwords for multiple online accounts so that you have to remember just one [master password](https://www.keepersecurity.com/resources/glossary/what-is-a-master-password/). 

**Use unique passwords** for every account. _A [unique password](https://cybernews.com/best-password-managers/how-to-create-a-strong-password/) is a combination of uppercase and lowercase letters, numbers, and special characters_. It should be long and not so obvious, like your pet’s name.

## Use Proxies

**Conceal your location** by using tools like [Proxidize](https://proxidize.com/). When email traffic passes through a [proxy server](https://en.wikipedia.org/wiki/Proxy%5Fserver), the sender’s IP address is hidden and reputed through a third-party server, preventing threat actors from tracing the origin of the email. 

A proxy is like a buffer between your inbox and external attackers, segregating spam and [phishing emails](https://www.expresscomputer.in/news/check-point-software-90-of-company-attacks-start-with-a-phishing-email/111560/) from genuine ones. What’s better is that **proxies also encrypt emails in transit** and at rest so that nobody tampers with sensitive data.

## Use MFA

MFA is short for [multi-factor authentication](/email-security/multi-factor-authentication-mfa-and-its-impact-on-email-security/), an extra security layer that protects your email account from illegitimate and ill-intended logins. _By using MFA, you **minimize the probability** of a cyberattack, as more than one piece of evidence is required to confirm a user’s identity_. The other evidence can be OTPs, [hardware tokens](https://gkaccess.com/support/information-technology-wiki/hardware-token/), fingerprints, facial and **voice recognition**, etc. Also, custom multi-factor authentication policies improve users’ productivity. 

[![Multi-Factor Authentication](https://media.mailhop.org/duocircle/images/2024/04/phishing-protection-2.jpg)](https://media.mailhop.org/duocircle/images/2024/04/phishing-protection-2.jpg)

## Use Email Authentication Protocols

[Email authentication](/resources/email-authentication) is a process of deploying protocols that check the **sender’s authenticity** and ensure nobody alters emails in transit. This helps prevent phishing and [spoofing attempts](https://fox59.com/news/major-phishing-attempt-targeting-verizon-customers/) made in your company’s name. There are three primary email authentication protocols that you can deploy in 2024-

### Sender Policy Framework or SPF

To deploy [SPF](/content/spf-record-check), you have to create an [SPF record](/content/spf-records) that includes all the IP addresses authorized to send emails on your behalf. Then, you publish the SPF record on your **domain’s DNS** so that recipients’ servers can look into it to verify whether the sending source is legitimate and authorized. If yes, emails land in the **primary inboxes** of recipients, otherwise, they get placed in spam folders. Sometimes, they even bounce back.

[![brand reputation](https://media.mailhop.org/duocircle/images/2024/04/hosted-email-server-4092.jpg)](https://media.mailhop.org/duocircle/images/2024/04/hosted-email-server-4092.jpg)

### DomainKeys Identified Mail or DKIM

Upon deployment of [DKIM](/resources/what-is-dkim), outgoing emails are signed digitally using a [private cryptography key](https://www.techtarget.com/searchsecurity/definition/private-key). Upon reception, the recipient’s server uses the public key to verify the source of the message and **ensure nobody tampered** with it in transit.

DKIM also prevents emails from being marked as spam since **ISPs trust** it to build and enhance [brand reputation](https://www.wix.com/blog/brand-reputation).

### DomainBased Message Authentication, Reporting, and Conformance or DMARC

[DMARC](/email/dmarc) is based on SPF and DKIM. It basically instructs recipients on how to deal with unauthorized emails sent from your domain. You can choose one of the three policies, **none, quarantine, or reject**. _The ‘none’ policy directs recipients to **do nothing** with [unsolicited emails](https://www.livemint.com/companies/news/uber-spam-emails-australia-hits-company-with-aus-412-500-fine-for-breaking-laws-11698294051004.html), while the ‘quarantine’ and ‘reject’ policies instruct recipients to mark them as **spam or block** them outright._

Remember that just one or two [email security](/content/email-security-services) measures won’t suffice. You have to **leave no room for threat actors** and thus use multiple security elements.
