Reoon Email Verifier Reviews

I’ve been using this tool for about a year now. It’s very reliable and has helped us prevent bouncing by 20%. It helps our clients to address incorrect emails on the spot. It has many integrations that I recommend leveraging via API. We use it on Boost.Space and Make.com but it’s available on several other no-code automation platforms. I suggest using power mode when running verifications on API. The quick mode is often inaccurate. API Power mode is quite helpful though, most often resulting in a deliverability score. We have purchased multiple accounts on all tiers for this tool as it’s become a core part of our daily operations. Highly recommended for contact validation in marketing and patient email accuracy in healthcare.

I have tried many verifiers and Reoon really works. I use sendmails.io (also AppSumo) and it’s integrated but having API as a developer is perfect and really fast.

I stumbled upon Reoon twice: on my own and while browsing AppSumo one day. I was so happy to give them a try and I am so glad I did. DO NOT be fooled by the simplicity of their website: these tools are FOR REAL. I love how well the email verifier works and I am relying on it 100% for my campaigns. It is FAST and it seems to be very accurate: what else can you ask for? Wait! Their customer service is also fast and courteous. I am really impressed... REALLY.

This is one of the best affordable email verfier. It easily handles large email lists and gives clear results with valid, invalid, and risky categories — which saves a ton of time when cleaning up databases.

The interface is clean and beginner-friendly, and I really like how quickly it processes bulk emails without crashing or lagging. The best part is its reliability — it consistently catches invalid or fake emails that other tools sometimes miss.

Customer support is also super responsive and helpful whenever I have questions.
Overall, Reoon is one of the most reliable and affordable email verification tools I’ve used — highly recommended for marketers, recruiters, and anyone managing large contact lists!

Even though I was using a different service to verify emails. I am very happy with the simplicity of Reoon for getting through large email lists.
