"Fantastic tool to validate email addresses automatically"
What do you like best about Clearout?

We just synced up out bulk email software (Moosend) and then the list was pulled to Clearout. After selecting a couple of options the list had been validated and push back to Moosend. This saves our email reputation and stops bouncebacks. Highly recommended.

What do you dislike about Clearout?

Nothing - it does what it says and is very easy to use. Great support even on a bank holiday!

What problems is Clearout solving and how is that benefiting you?

Keep our email lists clean

"Great Scrubbing Tool For the Price"
What do you like best about Clearout?

Really simple to use, accuracy of the scrubbing seems good. Exceptional support.

What do you dislike about Clearout?

No issues that I have found so far, but have only used in a limited capacity to date. Slightly slow analysis but good work takes time.

What problems is Clearout solving and how is that benefiting you?

Building a more accurate email list to talk to the right people. Eliminating bad emails helps save money and delivers to the right people.

"Clearout really helps keep the "trash" out."
What do you like best about Clearout?

Other than their awesome software, their support is amazing! Our team needs support every now and then and we've found not just the software but the support team to be amazing.

What do you dislike about Clearout?

Nothing, specifically. The UI could be a bit smoother, but it is really nice all the same. I have to say that other than the look, the software is really intuitive and easy to use.

What problems is Clearout solving and how is that benefiting you?

We're keeping our business email list of subscribers clean and validated through Clearout. This improves our open rates and ensures that only real email addresses are being emailed to. It also keeps our autoresponder costs down. We've also heard about the telephone validation service of Clearout. We'll probably use it sometime in the future. Currently, we're focusing on using the email validation service.

"An awesome product, great API and support"
What do you like best about Clearout?

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 It was able to identify about 10% of the contacts in our contact database as being no longer valid (invalid).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.

What do you dislike about Clearout?

Some of the technical documentation could be a bit more detailed but that isn't critical.

What problems is Clearout solving and how is that benefiting you?

I needed to validate the deliverablity of our email marketing list and also know which of our contacts at companies had left those positions. Since we've been in business for a while we wanted to clean out the relationships that were no longer valid. We also have used it to help our customers cleanup their lists.

"Reliable service - verification via API always works"
What do you like best about Clearout?

Support is great. Pricing is also great.

What do you dislike about Clearout?

I wish I could have two sets of API keys.. they just provide one, but I'd like to have separate keys on different systems.

What problems is Clearout solving and how is that benefiting you?

I can now validate all emails from apps, so entered data is clean.

"Great tool to validate email addresses lists"
What do you like best about Clearout?

I like Clearout because it's a fast and accurate tool to validate email addresses. I tried other similar tools, but no one of them was precise as Clearout. Also, Clearout permits to add the lists to check from variuos sources, like a local file, Mailchimp, ActiveCampaing, Moosend or Hubspot. When the validation process had ended, you can download the entire file with the results, or only the valid addresses.

What do you dislike about Clearout?

No, I can't find any negative point in Clearout.

What problems is Clearout solving and how is that benefiting you?

Clearout permits me to clean old email addresses lists from wrong, old and unused addressed, in a simple and effective way.

"I didn't realize I had such a messy database"

Clearout gave us a clearer understanding of our deliverability and also duplicates and dead emails. It has saved us money reducing our database size and deliverability.

What do you dislike about Clearout?

We have not experienced anything negative about the system

What problems is Clearout solving and how is that benefiting you?

We are solving our deliverability issues and also removing dead leads and "looky-loos" from our database. It feels like we have a much more serious email marketing operations
