Proofy has become a go-to in my workflow. I manage outreach for multiple clients in the home services space and list quality is everything — a dirty list tanks your sender rep fast. Proofy makes the whole process effortless. Upload your list, get a clean breakdown of valid, invalid, duplicates, and role-based addresses, done. No bloated dashboard, no upsell every time you click something. The pricing is the most straightforward I've seen — you know exactly what you're paying and what you're getting. Honestly refreshing compared to the bigger names in this space that nickel and dime you. If you're running any kind of outbound email operation and you're not cleaning your lists, you're leaving deliverability on the table. Proofy makes it easy enough that there's no excuse not to
Cons: That I didn't find it sooner. Would've saved me a lot of money on overpriced alternatives. Love this software
Deylan R. · CEO · Marketing and Advertising · May 4, 2026
My overall experience with Proofy has been very positive. The platform delivers exactly what it promises, allowing me to validate email lists quickly, easily, and efficiently. Since I started using it, I have noticed a clear improvement in my cold email deliverability, along with a significant reduction in bounce rates. This directly helps maintain a healthy domain reputation. It’s a tool that fits perfectly into my prospecting process and one that I use regularly.
Pros: What I liked most about Proofy is the accuracy of its email verification and how easy the platform is to use. In just a few minutes, I can upload a list, analyze the results, and export only valid contacts. This greatly improves my email deliverability and helps protect my domain reputation. Additionally, the pricing is affordable and the system remains fast even with larger lists.

Cons: From my point of view, there is nothing significant to improve. The platform’s layout is very minimalist, straightforward, and easy to understand, which makes it very practical for daily use. As a suggestion, it could be interesting to add a language switching feature to better serve users from different countries.
Andre F. · Empresário · Marketing and Advertising · March 28, 2026
I had a great experience, the interface is really intuitive and easy to use and there are different options depending on your volume of emails with the bulk verifier thing that I find particularly helpful for my case
Pros: I got the best accuracy emails, even more than with most much more expensive platforms. And I was even able to achieve a 0% bounce rate !
Cons: I did have to make the emails go through the verifier 2 times becauss there were still some bad ones after the first use but everything was clean after the second. So that is just a little something the proffy team should think about.
Liz-Anna Y. · Automation consultant · Human Resources · March 26, 2026
Pros: Easy to use platform with a the capability to upload CSV files directly. The price point on this service is also unbeatable.
Cons: I searched for contact solutions for awhile trying to find the best way to filter out inaccurate emails and Proofy did not come up automatically as a top choice However, they are worth the digging and I am glad I found them for my contacts project.
Edward A. · Systems Manager · Construction · March 12, 2026
My overall experience with Proofy has been very positive. The platform is reliable, easy to use, and very effective for cleaning email lists and improving deliverability. It helped reduce bounce rates and maintain a better sender reputation for our email campaigns.
Pros: What I liked most about Proofy was how easy it is to validate email lists and improve campaign deliverability. The platform is fast, simple to use, and helps reduce bounce rates while maintaining the domain’s reputation.
Cons: One downside is that the pricing can become a bit expensive when verifying very large email lists. However, the quality of the verification usually compensates for that.
Denis S. · Ceo · International Trade and Development · March 3, 2026
So far, my experience has been smooth and efficient. The setup is quick, the interface is clean, and the verification results are delivered promptly. Even in the trial phase, it feels like a practical solution for improving email list hygiene and reducing potential delivery issues. The tool saves time, protects sender reputation, and increases confidence when launching campaigns. For teams that care about long-term deliverability and list hygiene, it’s a solid and reliable solution.
Pros: I recently started testing Proofy and my first impression is very positive. The platform is straightforward and easy to navigate. Uploading a list is simple, and the verification process is fast. What stood out to me is how clearly the results are categorized, which makes it easier to understand the quality of the email list before launching a campaign. For anyone working with email marketing, having this level of clarity is very useful.
Cons: Since I’m still in the early stages of using the platform, I haven’t explored all features yet. It would be helpful to have more built-in guidance or short walkthroughs for new users to maximize the tool from day one.
José Manuel D. · Founder · Marketing and Advertising · March 1, 2026
Nice ! I found it and tried it thanks to various reviews on the internet, which gave me confidence in the confidential management of my data.
Pros: I appreciated how easy and quick it was to use compared to other solutions available. The results are fast and accurate when verifying email addresses. The free trial is very interesting and gives you an idea of how effective it is.
Cons: Nothing this is a great tool to help daily works. Being able to delete email addresses that are closed or change regularly is very useful for lists containing several thousand contacts.
Paul S. · Sales manager · Wine and Spirits · January 14, 2026
The user experience, the speed of verification, the results of verification, and the cost is really good. I've tried so many apps before but Proofy is extremely reliable and I can count on it to verify thousands of leads.
Pros: It's easy to use. Credits never expire even after updating to a new app. Proofy just gave all the credits and they passed off all the credits.
Cons: I have found no problems in Proofy. Usually the biggest problems when it comes to similar tools is the accuracy of the tools but the accuracy of Proofy is very high.
Gaurav P. · Owner · Marketing and Advertising · January 6, 2026
Really nice tool , if your a freelancer like me its a life saver to protect your emails from backlisting coz of hard and soft email bounce
Pros: its really nice budget friendly email verifier APIs are pretty smooth to work with dont break easily
Cons: using it in google sheets app script it might cause timeout coz sometimes it takes little longer for huge data rows
Aditya S. · Video Editor · Media Production · January 5, 2026
My overall experience with Proofy.io has been excellent, the platform is reliable, responsive, and fast. Emails are verified accurately, support is helpful, and the service offers great value for money
Pros: They’re very responsive, any issue you text to support, they solve quickly. Great value for money, with perfectly verified emails. A solid platform to use
Cons: Proofy.io offers responsive support, fast and accurate email verification, and good overall value, though one drawback is that I sometimes end up paying for a high number of invalid emails
Tekla M. · Marketing Executive · Marketing and Advertising · November 19, 2025
Pros: The thing with large database is that it gets old and outdated soon. Proofy helps eliminate the dead email ids without risking a hit to your email domain health. Plus its easy to use with just uploading the excel files and getting the corrected data in a few minutes.
Cons: There can be more documentation how my data is secured and is free from risk if its confedential.
puneet y. · marketing manager · Computer Software · March 5, 2025
Solid API, great trial functionality... hard to think of a downside. I wish all our vendors were this reliable and easy to work with.
Pros: From what we can tell about 4% of people make a typo entering their email address. Proofy fixes this in real time and it's great value for money. Highly recommended A+
Cons: Nothing really, though I prefer not to pay with Paypal
Colm G. · Solutions Architect · Hospital & Health Care · February 19, 2025
Will the experience has been great I loved every part of the service and I would rally recommend it to my friends

Great, most of the time I enjoy and accuracy is quite good.
Pros: Very user friendly and smooth onboarding

Rishabh P. · COO · Information Technology and Services · January 1, 2025
Pros: I liked it. I was not expecting the verifying results that fast.
Cons: It could be better if I could directly paste multiple emails instead uploading.
mehmet a. · Ship Chandler · Transportation/Trucking/Railroad · December 27, 2024

Leandro V. · Representante · Business Supplies and Equipment · December 26, 2024
Good, I have used this product, this is very cheap also
Pros: Process is easy, results are fast, Refunded if not used properly
Cons: Risky Part , in the result sheet, i do not know whether to use it or not
Rakesh S. · Marketing Exe · Computer & Network Security · December 19, 2024
Pay as you go is so amazing!, that it overways any cons that the platform may have.
Pros: The fact of pay-as-you-go pricing. Let's say I need to verify 10k emails – I just purchased the amount I need to verify without a subscription.
Cons: The UI could be better, as now it looks kind of oldschool.
Sean G. · Art Director · Design · December 16, 2024
Very Good, easy to navigate verify API is useful
Pros: Instant result category after uploading data
Cons: High unknown emails category in the list
Faiz A. · Director · Accounting · December 16, 2024

Cons: nothing in particular, but we could say nothing is perfect
Timothy m. · manager · Professional Training & Coaching · December 11, 2024
Easy to use, downloadable excel with verification status.
Pros: This is a time saver. If you have a lot of e-mails and want to update your list, it helps a lot.
Cons: To be honest, so far, no less positive things.
Giovanni E. · Consultant · Health, Wellness and Fitness · December 3, 2024
Pros: very easy to use and very much accurate data
Cons: to be honest there's nothing that I would like the least with Proofy but sometimes it is having a connection issue may be that.
Rajith D. · Sales Executive · Telecommunications · November 29, 2024
Decent tool for email validations and output
Pros: Easy to use, just upload and download the data
Cons: Sometimes data/email validation is incorrect
Amb P. · CMO · Marketing and Advertising · November 28, 2024
Pros: The speed and simplicity of Proofy when analyzing any mailing list, since I have had many problems with the statistics of my mass mailing campaigns.
Cons: The free plan is up to 100 emails, however for freelancers with few emails it is quite good.
