**Subaddressing** | Optional | An alternative to aliasing is [subaddressing](https://en.wikipedia.org/wiki/Email_address#Subaddressing), where anything after the `+` symbol is omitted during mail delivery, for example you the address yourname+tag@example.com denotes the same delivery address as yourname@example.com. This was defined in [RCF-5233](https://tools.ietf.org/html/rfc5233), and supported by most major mail providers (inc Gmail, YahooMail, Outlook, FastMail and ProtonMail). It enables you to keep track of who shared/ leaked your email address, but unlike aliasing it will not protect against your real address being revealed
**Use a Custom Domain** | Advanced | Using a custom domain, means that even you are not dependent on the address assigned my your mail provider. So you can easily switch providers in the future and do not need to worry about a service being discontinued
**Sync with a client for backup** | Advanced | Further to the above, to avoid loosing temporary or permanent access to your emails during an unplanned event (such as an outage or account lock). Thunderbird can sync/ backup messages from multiple accounts via IMAP and store locally on your primary device
**Be Careful with Mail Signatures** | Advanced | You do not know how secure of an email environment the recipient of your message may have. There are several extensions that automatically crawl messages, and create a detailed database of contact information based upon email signitures. If you send an email to someone who has something like this enabled, then you are unknowingly entering your details into this database
**Be Careful with Mail Signatures** | Advanced | You do not know how secure of an email environment the recipient of your message may have. There are several extensions (such as [ZoomInfo](https://www.zoominfo.com)) that automatically crawl messages, and create a detailed database of contact information based upon email signitures, and sometimes message content. If you send an email to someone who has something like this enabled, then you are unknowingly entering your details into this database
**Be Careful with Auto-Replies** | Advanced | Out-of-office automatic replies are very useful for informing people there will be a delay in replying, but all too often people reveal too much information- which can be used in social engineering and targeted attacks
**Choose the Right Mail Protocol** | Advanced | Do not use outdated protocols (below IMAPv4 or POPv3), both have known vulnerabilities and out-dated security.
**Self-Hosting** | Advanced | Self-hosting your own mail server is not recommended for non-advanced users, since correctly securing it is critical yet requires strong networking knowledge - [read more](https://www.reddit.com/r/selfhosted/comments/6h88qf/on_selfhosted_mail_servers/). That being said, if you run your own mail server, you will have full control over your emails. [Mail-in-a-box](https://github.com/mail-in-a-box/mailinabox) and [docker-mailserver](https://github.com/tomav/docker-mailserver) are ready-to-deploy correctly-configured mail servers that provide a good starting point
