Double opt-in dependencies
This plugin is an add-on to <a href="https://wordpress.org/plugins/contact-form-7/" rel="ugc">Contact Form 7</a> plugin by Takayuki Miyoshi. 
Functionality of this plugin also depend on installing and activating one of the plugins, which saves Contact Form 7 submissions to WordPress database. At the time, compatible plugins are:
<ul>
<li><a href="https://wordpress.org/plugins/flamingo/" rel="ugc">Flamingo</a> by Takayuki Miyoshi</li>
<li><a href="https://wordpress.org/plugins/contact-form-cfdb7/" rel="ugc">Contact Form 7 Database Addon – CFDB7</a> by Arshid</li>
</ul>

</ul>
Additional enhancements

<ul>
<li>Custom, accessible file upload inputs for your forms which look better, can be CSS styled and allow easy selecting and deselecting files to upload. This works for every CF7 form, not only double opt-in enabled.</li>
<li>Custom, more specific validation errors for radio buttons and checkboxes for improved accessibility.</li>
<li>Option to change CSV separator when exporting submissions from Flamingo plugin. It also adds BOM to CSV exports, allowing them to be properly opened in MS Excel. </li>
<li>Additional column on Flamingo Inbound Messages screen indicating if submission is complete or still waiting for being confirmed by sender.</li>
</ul>
What is double opt-in and why use it:
Double opt-in is the safe way of receiving site visitor’s submitted input. Used with contact forms or online questionnaires or with user registration, it helps to reduce spam submissions. With GDPR laws, double opt-in is a strongly recommended way of getting user data. Because submitters have to confirm their identity from their email address, you can reduce risk of processing personal data without permission. Double – means here that user submitting the data has to give consent by checking checkbox option and additionally confirm their email-address. 
Do not forget to set acceptance field in your CF7 form if GDPR is in concern!
How Double opt-in form works:
When someone fills and submits a form with double opt-in functionality, the first CF7 email goes back to THEM. There is a confirmation link in that email, which the submitter has to click on or paste in their web browser. The link has two encrypted parameters: submission serial number and submitter email address. The page with “opt-in” slug validates the parameters with submission stored in WordPress database and initiates sending of final emails to recipient set in “All Opt-In Forms” settings. If validation fails or when submission has expired, no emails are sent. If there are no specified parameters in the URL, visitors of the “opt-in” page are redirected to “404” page.
Plugin translation
Double Opt-In can be easily translated. It is released with the translation to Polish language.

<h3>Why should you have a multilingual website?</h3>
It’s easy to forget all about other languages when setting up your online business! With the resources needed to put together a new website, multilingual capabilities are very commonly ignored, as the process of getting multiple translations can get complicated and expensive. But ignoring the importance of being multilingual can be a costly mistake: unlocking the possibility for visitors to read and interact in their own language means you’ll be significantly widening your reach, increasing your chances of business success!
This is why it’s important to think of ways to offer translations in more languages: multilingual websites naturally rank in more countries and attract more potential customers. Your visitors will also feel like you are significantly more localized by speaking to them in a language they easily understand!
But how about the cost and headache to set up a proper multilingual website offering high quality translations? This is where Weglot can make it easy: with a simple way to unlock multilingual capabilities swiftly, your website can go from targeted towards a single language to multilingual in an easy, affordable manner!

Translate WordPress and go Multilingual – Weglot AI Translation Plugin

I'm not an authority on translated text, but as far as I can see the automatic translation works well and we are also able to add our manual transitions where needed. Support is reliable, helpful and fast.

Works well!

Awesome

Very easy to use and very helpful support. Recommended. 

Easy to use and very helpful support


It does not have a free option, it gives only a free trial. You can easily reach their 2000 words limit. Maybe with 2-3 posts? Why are wordpress admins still keeping this plugin here? Lots of plugins here only offer a free trial or pro features and they keep advertising these plugins here. They can advertise their paid plugin on their website.


Why this plugin is here?

Great plugin and support!


We’ve been using Weglot on our client’s site for 2 years now, and we’re super satisfied with it! It’s a very complex project with custom-built translations for specific site needs, and Weglot fits perfectly alongside them.



The plugin provides fast and high-quality translations that make managing a multilingual site so much easier.



Their support team is amazing—fast, friendly, and super knowledgeable.



If you’re looking for a multilingual solution for WordPress, we highly recommend Weglot!


Good tool with grate support


Una manera sencilla y rápida de tener traducida una web. El soporte que ofrece Weglot es excelente, me han resuelto varias dudas de forma rápida y eficiente.


Buen plugin y buen soporte


We recently encountered an issue where enabling the Weglot plugin caused blank PDFs when using PDF Invoices & Packing Slips for WooCommerce. The Weglot team was incredibly responsive — they quickly identified the cause and released a fix. After updating to the latest version, everything is working perfectly again.



It's rare to see such fast and effective support. Weglot not only offers a great translation solution but also backs it up with excellent customer service. Highly recommended!


Fast and Effective Support!


I want to thank all the people who helped me with my issue. Even though it looked like it was impossible to find a solution they did it in the end.


Excellent support from Antoine


Not only is this a great out-of-the-box solution, their support is amazing.  We'll be using this on many projects.  


Amazing Support


I hate to go against the reviews here, but support is not helpful.



I couldn't set up the plugin locally, provided the response from their API, they requested a video as well.



I'm pasting the response I got from support after:




Thanks for the video ;)



In fact, it is a really strange behavior because I tested the API key on a local test website I have (a .local one), and it is working perfectly.



Do you have another local website on which you could test it?




At this point I decided to self support myself. 



I can't help but think I lost my time speaking to a person who basically told me to reboot my machine, in IT terms. "Works on my local". That's great ... for this support person I guess.



I don't recommend this plugin if you run into issues that require support to think about the problem at  hand and not following a defined set of rules. Based on my experience you will lose time that could better be spent figuring it out by yourself. 


Terrible support.
