However, if you run a business and have a website, you are in control of what people submit to your website. One solution to the problem is called Oopspam anti spam.
This is a great plugin that you can embed in your website’s submission forms. When someone submits their email address (e.g., to subscribe to your blog, book a demo, or grab a lead magnet), Oopspam uses a combination of machine learning tools and an extensive database of emails to tell you if the submission was spam or not.
So, how does it work, and should you get it for your website?
What is Oopspam anti spam?
Oopspam is an anti-spam and abuse protection service that protects websites and online platforms from malicious forms, comments, and other input submissions. In other words, whenever someone wants to submit a spammy email and message (on their own or with a bot), Oopspam stops them.

The biggest benefit is that you won’t receive an email list filled with spammy, invalid, outdated, incomplete, and irrelevant data.
Oopspam prides itself on several things:
- 99.9% accuracy, allowing you to get virtually every good submission through
- 100% accessibility, which means that the user doesn’t have to take additional action to push their submission
- No puzzles that could kill your conversions and put website visitors off from submitting their details
- Fast website performance, as Oopspam doesn’t need JavaScript, special fonts or CSS
How Oopspam works
OOPSpam uses a combination of machine learning and advanced filtering techniques to detect and block spam messages across websites and applications. Here’s how it works:
- Machine learning analysis
OOPSpam’s spam detection engine is powered by constantly updated machine learning models that identify patterns typical of spam content. - IP and email reputation checks
It checks the sender’s IP address and email domain against a global list of known spam sources (built by various cloud providers) to block suspicious activity. - Content analysis
The system evaluates the message content to effectively detect spam keywords, excessive links, or suspicious formatting typically found in spam log submissions. - Customizable filters
Users can refine their spam filtering by setting up rules such as:- Blocking or allowing specific countries
- Setting preferred languages for submissions
- Blocking disposable or temporary email addresses
- Spam scoring and reports
Every submission is assigned a spam score along with a detailed explanation. This helps users fine-tune their filters and understand why a message was flagged.
Last but not least, Oopspam integrates with various platforms to help you get to non spam entries.
Setting up Oopspam on your form submissions is not as simple as dragging and dropping a few fields. Depending on the platform where you want to integrate it, you’ll need varying degrees of programming knowledge to create your spam prevention setup.
For non-developers and those needing a bit of help, Oopspam has detailed API documentation available on their website.
Oopspam integrations
Oopspam has a modern spam filter that you can’t use on its own. Unlike other platforms and services where you can validate emails, here you have to use the Oopspam API, which integrates into your website or e-commerce platform.
Some of the most popular platforms that Oopspam integrates with include:
- WordPress
- Zapier
- Make.com (formerly known as Integromat)
- The.com
- Bubble
- Craft CMS
- Better Blog Comments
- Judge.me
You can use the Oopspam API to embed this tool and capture data on form submissions, helping you with spam and abuse detection on your website. In other words, you can block submissions with fake, spammy emails thanks to Oopspam’s high accuracy.
To integrate everything on your website, you only need a valid API key and some knowledge of code.
