Spammers unfortunately love using bots to send Spam, and this automated form spam can be as much of a problem as general email spam coming into your inbox. Setting up protection on your forms is important to reduce the form spam.

Please note, even with reCAPTCHA added onto your forms, it is still possible you may still get a few spam emails each day. What is less obvious is that reCAPTCHA is still filtering out upwards of 80% of the spam that would otherwise be coming through.

Why doesn't reCAPTCHA solve all spam?

Quite simply, as technology is built to stop spam, spammers get smarter and find ways past this technology, so they are usually one step ahead of spam protection tools on the internet.

What is reCAPTCHA?

reCAPTCHA is a free service that protects your website from spam and abuse. reCAPTCHA uses an advanced risk analysis engine and adaptive CAPTCHAs to keep automated software from engaging in abusive activities on your site. It does this while letting your valid users pass through with ease.

Is form spam a virus?

Form spam may contain links to sites with viruses on them, but the actual form spam itself is not a virus. 

Step 1 - Generating your key

To create your key click here and follow Google's instructions. You will need to login to your Google account or register one to be able to continue the setup process.

Once you get to the step of registering a new site, these options shown in the screenshot should be filled out:

Label This is solely for your own purposes and only visible to you for future reference. So if you look at this in the future you know what you used this key for. It could be something like 'Limecube form protection'
reCAPTCHA type

Choose 'reCAPTCHA v3'

Domains It is recommended to add both:
  1. Your live domain name. e.g.
  2. Your temporary domain (web address) if you are setting this up prior to going live (this can be copied from your browser address bar)

It should not include https:// or www.

Owners This is your account email address. Typically there is no need to add any additional email addresses.

Your keys will then look like this: (these are not real keys and cannot be used)

Step 2 - Inserting your key into your Limecube website

The next step is to take your keys generated in the step above, and insert them into your Limecube website. 

Go to your top menu, then: 'More' > Administration > Settings > Security

Watch this video below to see how.

Please make sure you test your forms after adding reCAPTCHA to make sure you receive the form emails. And always check junk mail if it does not land in your inbox. :)
