  • Logic Inbound Hayk Saakian, Cofounder and COO

    One of my friends suggested that I use clearout to help improve the success rate of our email campaigns. I didn't use to think that deliverability really mattered. After trying clearout I almost never see any bounces or failed deliveries and our open rate is as high as 82% sometimes because the quality of our list is so good now. The "guaranteed deliverable" feature gives us a lot of confidence in clearout as a product. I expect to use this tool for as long as we're in business and I recommend it to anyone I know who sends lots of emails.

  • Pearl Lemon Deepak, Founder

    As a lead generation agency sending out over 20,000 emails a month internally and for our clients, Pearl Lemon Leads were looking for a provider that could help us clean emails at scale. Clearout has proven to be an excellent resource to help us with that journey. Increasing our deliverability by 23% in some cases. It’s now part of our ‘go-to’ tool stack for outreach campaigns.

  • SigParser Paul Mendoza, Co-founder

    "An awesome product, great API and support" It works amazingly well at validating email addresses. It was able to identify about 10% of the contacts in our contact database as being no longer valid (invalid). At first, I thought it was wrong but it turned out it was right. We double-checked most of them and it was correct in that most of those people had moved onto other jobs. There are other products out there for email verification but Clearout was by far the best price and easiest to use. We ended up building an integration to Clearout from our product SigParser using the Clearout API.

  • Marcus W K Wong, Head of Marketing

    Clearout has provided me with a simple solution for validating emails and tidying up our email database at I recommend this to fellow marketers who are on the market for an email validation tool, and I look forward to the updates and new releases from Nida and the team!

  • YEAH! Local Justin Herring, Co-Founder

    I had been looking at Clearout to purchase but without an ActiveCampaign integration, I was going to have to use Zapier and just didn't want the hassle. I reached out through their chat a couple of days ago and asked when this integration was coming and they didn't know. Then I got an email this morning from Clearout support stating the integration is now up and running for ActiveCampaign. Purchased it immediately and have already cleaned all my lists. That is some serious customer support!

  • HAMMER PUBLISHERS PVT. LTD. Sanjay Anand, Director

    Clearout is a great way to protect your sender reputation for email marketing. It detects and removes known abuse and spam trap emails, invalid, toxic and catch-all domains. It's not only a powerful tool of improving your deliverability., but it also offers you data about your subscribers that can be valued in marketing reports, it appends Domains Segregation as well. Clearout is fast and easy to use email validator. Price Comparison is a WORTH mention if you compare with Zerobounce or Neverbounce. Clearout clearly Stands Out. Now with added feature with no hidden price, an inbuilt Lead Generation tools further helps to build B2B leads/Data, which is very useful in today's changing digital scenario. I am extremely happy to use the software and would recommend all to buy this.

  • Aatracao De Clientes Marcelo Bacchi, CEO

    Clearout is easy to use and the verification is very fast. I use clearout in my business so that we can keep our email list clean and have a higher deliverability rate. In addition, we save a lot of money using only active contacts in our CRM. I highly recommend Clearout as we use the platform with great success.

  • Rafael Rojas Pérez, Psychologist, writer, speaker and lifecoach

    Email marketing is an amazing tool but having a cleaned list in your business is the most important thing when you're taking care of that niche. It ensures your domain won't be blacklisted and your emails are going to arrive to your clients, increasing your conversions and creating a deep relationship with your subscribers, clients and leads. Clearout is the most powerful tool when you're trying to do that: an easy dashboard, concrete statics and incredible support will consider your business as theirs and will take care of it. On the other hand is great to have integrations with the most important email marketing systems. Just leave your list in hands of Clearout.

  • Yusuf Rangwala freelancer on upwork

    I came across by chance and found out it to be the most cost-effective & user-friendly interface to use! I compared the effectiveness of the email verification with other tools in market and surely I could find the difference in quality.

  • Craig Brown Designer, Foxie Web Design

    Clearout is useful software, I was sent a client contacts list for a newsletter campaign that I could not verify on MailChimp, and worst of all, MailChimp's Omnivore system won’t tell you which emails MailChimp views as high risk. This guessing game could have earned up hours or days… without an email verification system like Clearout.

  • Carol Rycraft Founder, Rycraft Consultants

    I am running my online business for a long but was never into engaging with customers through emails. Lately, I planned to send out newsletters to my customers. I thought designing the newsletter would be the only hard part but the Mailpoet team informed me that relying on unscrubbed email addresses, collected over the years, can be dangerous. Using such data can get me blacklisted unless I use an email verifier to clean the list. I had no clue about email verification & was on the verge of giving up when I came in touch with the EXTRAORDINARY support system of Clearout. Not only did they answer all my questions with the utmost clarity, but they also gave me an online demonstration of how to go step by step. I cleaned 3 lists while on a Zoom call with them. A good team and a great product!
