th23

Provide your users and visitors a simple and straight forward contact form.
The modern design is very clear, easy to navigate and with light-weight JS and CSS code. One big benefit is its flexible positioning in pages and posts as a modern style block or classic shortcode.
To keep your website safe, it comes with built in spam and bot protection, by using Akisment and reCaptcha for messages sent by visitors. The plugin is continuously improved and used on live websites since 2012.
th23 Contact is built with some few goals in mind:
<ul>
<li>Simple and straight forward option for user to contact you</li>
<li>Light-weight code basis without overheads and frameworks</li>
<li>Easy to adapt styling to fit any page design and layout</li>
<li>Fight spam and bots without unnecessary hurdles (admittedly it’s a compromise)</li>
</ul>
See it in action on my <a href="https://thorstenhartmann.de/kontakt/" rel="nofollow ugc">Contact page</a>.
<h4>Usage</h4>
Simply insert a new <code>th23 Contact form</code> block into the post / page using the plus sign in the Gutenberg editor or start typing <code>/th23 Contact form</code>.
Alternatively use the <code>[th23-contact]</code> shortcode directly in the source code editor view of a post / page or insert it as a legacy shortcode block.
<h4>NOTE</h4>
The th23 Contact form block and / or shortcode can only be used once per post / page!
Any second instance in the same post / page will be ignored upon frontend rendering and not show up.
<h4>TIP</h4>
Ensure th23 contact form is enabled for the sepcific post / page – see admin area under <code>Settings</code> -> <code>th23 Contact</code>.

BuddyPress gives you some customization options for your emails by default but there are still some downsides:
<ul>
<li>Styling options are very limited</li>
<li>It uses its own mailer which doesn’t work very well with SMTP plugins</li>
<li>If you use an SMTP plugin BuddyPress emails switch to plain text</li>
<li>You can’t use the same email design for BuddyPress and other WordPress plugins</li>
</ul>
<h4>Features</h4>
<ul>
<li>Email design for desktop, mobile and webmail clients 
Create your template once and it looks great on every device</li>
<li>One template for all your WordPress emails 
WP HTML Mail is an all-in-one email solution. You can use the same template for your contact form emails (NinjaForms, WPForms, Contact Form 7, Gravity Forms, Caldera Forms, …) as well as your store (<a href="https://codemiq.com/en/downloads/wp-html-mail-woocommerce/" rel="nofollow ugc">WooCommerce</a> and <a href="https://codemiq.com/en/downloads/wp-html-mail-easy-digital-downloads/" rel="nofollow ugc">Easy Digital Downloads</a>) and of course WordPress own notifications (registration, comments, updates, …) </li>
<li>No coding required (but possible) 
You can customize your html emails without writing a single line of code but there are a few <a href="https://wordpress.org/plugins/wp-html-mail/#faq-header" rel="ugc">filters</a> for additional expert customizations.</li>
<li>Live preview 
Preview your email design live in your browser or send a test mail to get the best results.</li>
</ul>
<h4>BuddyPress PHPMailer and SMTP delivery</h4>
BuddyPress uses a customized instance of PHPMailer to send multipart email (plain text AND HTML at the same time). To make our email design work we have to switch to wp_mail() function which doesn’t work with multipart messages. On the other hand side this makes it possible to use SMTP plugins like Post SMTP Mailer, WP Mail SMTP and many more with BuddyPress.
