Clearout Email Validator – Real-Time Email Verification on WordPress Forms

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 78% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

At the current install trend, crossing 700+ in roughly 1406 days.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   I’ve been using this tool now for several weeks and have found it to be immensely helpful for my business. Just as important, when I reached out to customer service they were responsive and extremely supportive of my needs. I could not recommend this software more highly.

   I recently had the pleasure of interacting with the tech support team for this WordPress plugin, and I couldn’t be more impressed. They were prompt, professional, and extremely knowledgeable. Every query I had was addressed with patience and clarity, making the whole experience stress-free. The team went above and beyond to ensure my issues were resolved swiftly, and their guidance made a significant difference in optimizing my website. I highly recommend this plugin not only for its email verification and security features but also for the stellar support that comes with it!

   II have been using ClearOut for 5 years primarily to validate emails on my WordPress site through their plugin and for bulk email validation. Recently, I encountered a bug. A good way to assess a plugin’s reliability is by reviewing its support services, and ClearOut’s support has been effective. They accurately identified the bug and assigned me an engineer (rather than an assistant who provides basic troubleshooting steps). The issue was resolved promptly.

   I’ve been using Clearout on my WordPress/Woocommerce site for over a year and it has mostly been transparent in validating emails. However, I recently had a situation where a repeat customer opened a support ticket with us and they could not place an order. Their email was being returned as “gibberish” by Clearout even though it had previously worked fine. I checked the log in Clearout and found this as well. While the plugin is working as expected, there should be a feature to skip email validation for users/emails that have a role within WordPress. For example, my customers have a role of “Customer”. The only way I found to allow this customer to place an order was to add them to the white list in Clearout. Had the customer not reached out via a support ticket, I would have never known. Hopefully, this can be added as it would reduce the number of validations needed and prevent customer frustration.

   Using the plug-in for several years now, on multiple websites. It works great and helps to avoid spammers and create better contacts. Our situation is as follows: We use a freemium model for some digital products and also provide free helpful sites. We only request to provide a name and e-mail to send the download link to. There was quite some abuse, until I started to use ClearOut Email Validator.

   Since we’ve added Clearout to our site we’ve only had genuine members joining our platform. We’ve also had no more issues with after sales when customers buy from our online store and input their email incorrectly by accident. Clearout helps your users get their email right first time, which is amazing! The support is very proactive and helpful. The system to pay for this plugin is performance based – which is very fair. I highly recommend this plugin if you have a membership and / or ecommerce website – it’ll save you a lot of hassle and keep those ‘fake’ signups off your site!

   I give 4 star for the work did by this plugin, exactly as per our requirement. I am really happy to use this plugin. But on rare, some mails skip the validation and reaches inbox which is not suppose to happen. Already informed the team on this. Waiting for the update from them.
