MailShogun is a WordPress plugin that forwards domain emails (e.g. info@mydomain.com) to any Gmail account without creating dedicated mailboxes. The plugin has a built-in free email address. 
In many cases after a WordPress website has been built, there is also a need to add emails that will be branded with the same website domain. 
It’s a personalized email address using your domain name. For example name@mywordpressdomain.com.
A business email address makes a great professional impression.
Here are some options you may want to start with: 
name@mywordpressdomain.com 
sales@mywordpressdomain.com 
contact@mywordpressdomain.com
There are several other options, however, they present some disadvantages. 
There are domain registrants, such as GoDaddy, and other mail forwarding services, where, for example, info@mywordpressdomain.com will be forwarded to infomywordpressdomain@gmail.com. The limitation of these solutions, is that they are only one sided. If you want to send an email back it won’t have “yourdomain” suffix, it will be an email that comes from Gmail, which in some cases might make you look less professional. 
Other solutions include buying addresses from third party email providers. The most popular service is Gsuite by Google. If you want to have name@mywordpressdomain.com with Gsuite, you will have to open a new “company” in Gsuite and then define every address. Every address has its own storage. Limitations are – high price (around $5 per mailbox per month), and all of the definitions of these addresses are done from an eternal dashboard. Another disadvantage is that every address is a real mailbox. If employee1@mywordpressdomain.com should move to employee2@mywordpressdomain.com all past emails of 1 are staying forever in the storage of 1. It is very complicated to move these emails to another box. 
Mailshogun overcomes all these disadvantages with these unique features: It is an email forwarding system, but you can also send back emails from your gmail and your customer will receive the email from your unique domain. It is a full solution in both sides. There are no inboxes for the addresses, and it is very flexible- you can open, delete, modify addresses very easily. Perhaps you have info, webmaster, contact, sales emails, you can forward all of them to one Gmail address. All mail definitions are done from the WordPress standard admin dashboard – like any other plugin. Mailshogun is also cheap, as one address is free and others are $10 per year, which is 1/6 the price of Gsuite.
<h3>Important</h3>
Since Mailshogun plugin is communicating with external mail servers in order to provide its service, it means that the plugin is not independent. Make sure that your firewall or IP mapping has access to https://api.mailshogun.com.
<h3>How it works</h3>
If you define one address from info@my-domain.com that will be forwarded to info-my-domain@gmail.com, this information is stored in Mailshogun servers and configure the servers accordingly. The actual forwarding is done there. 
This is exactly how it works if you define Gsuite or other external email. 
In addition to the communication with mailshogun servers, there is also connection to Paypal. This is optional, only if you choose to use the premium version that will allow forwarding of more addresses. The free version has 1 address.

</ul>
Anti-spam Reloaded plugin blocks 100% of automatic spam messages in comments section and also blocks all trackbacks.No captcha required.

Anti-spam Reloaded plugin is GDPR compliant and does not store any other user data except of the behaviour mentioned above.
Plugin blocks spam only in comments section.. 
Plugin does not block manual spam (submitted by spammers manually via browser).
<h3>Compatibility</h3>
All modern browsers and IE11+ are supported. 
Anti-spam Reloaded plugin works with disabled JavaScript. Users with disabled JavaScript should manually fill current year before submitting the comment.
Server compatibility:
<ul>
<li>WordPress 3.3 – 6.5</li>
<li>PHP 5.6 – 8.2</li>
<li>Doesn’t use jQuery</li>
</ul>
Plugin is incompatible with:
<ul>
<li>Disqus</li>
<li>Jetpack Comments</li>
<li>AJAX Comment Form</li>
<li>bbPress</li>
</ul>
If site has caching plugin enabled and cache is not cleared or if theme does not use ‘comment_form’ action 
and there is no plugin inputs in comments form – plugin tries to add hidden fields automatically using JavaScript.
<h3>How does it work?</h3>
The blocking algorithm is based on 2 methods: ‘invisible js-captcha’ and ‘invisible input trap’ (aka honeypot technique).
<h4>‘invisible js-captcha’</h4>
The ‘invisible js-captcha’ method is based on fact that bots does not have JavaScript on their user-agents. 
Extra hidden field is added to comments form. 
It is the question about the current year. 
If the user visits site, than this field is answered automatically with JavaScript, is hidden by JavaScript and CSS and invisible for the user. 
If the spammer will fill year-field incorrectly – the comment will be blocked because it is spam.
<h4>‘invisible input trap’</h4>
The ‘invisible input trap’ method is based on fact that almost all the bots will fill inputs with name ’email’ or ‘url’. 
Extra hidden field is added to comments form. 
This field is hidden for the user and user will not fill it. 
But this field is visible for the spammer. 
If the spammer will fill this trap-field with anything – the comment will be blocked because it is spam.
