Mailcheck Questions

A: Hi puneet1978,
Great follow-up!
On average, after verifying your list through Mailcheck, you can expect deliverability rates to reach 95–98% assuming you're sending to our “Valid” emails only.

We help remove not just invalid addresses, but also temporary, risky, or role-based emails that can hurt your sender score. Plus, with our enrichment and social signals, you're not just reaching inboxes - you're reaching real people. 📬✨
Of course, overall deliverability also depends on your email content, sender domain, and sending practices but our system does the heavy lifting on the hygiene side.

A: Hi puneet1978,
Thanks for the question! 🙌

Mailcheck and Reoon are quite different in how they’re structured and what they’re built for. With Mailcheck, the focus isn’t just on raw validation volume — it’s about long-term deliverability and improving your cold outreach results over time. 📈

The monthly limits are set with sustainability in mind. Instead of offering one big chunk of credits that might go unused or expire, we’ve designed the plans to support consistent, high-quality validation month over month. This helps maintain list health and keep your sender reputation strong. ✅
What also sets Mailcheck apart is the depth of integration with platforms like Mailchimp, Zapier, WordPress, Make.com, and even social networks — so you can turn valid emails into actual leads. 🚀 It’s more than just a verifier; it’s built to support your full outreach workflow.

Reoon might offer more upfront credits, but Mailcheck is designed to be a leaner, smarter solution for ongoing growth and better engagement. 💡

Hope that helps clarify the difference — happy to answer anything else! 😊

A: Great question! 👋
There’s no daily limit, credits are renewed monthly. So if your plan includes 2,000 checks per month and you use them all in one day, you’ll just need to wait until the next renewal to continue.
For example, if your file has 5,000 emails and you’ve stacked 1 code (2,000 checks/month), the system will process the first 2,000.
Hope this helps! Let us know if you have more questions 🙌

A: Thanks for reaching out and raising this question - it’s an important one.

Mailcheck is designed primarily as an email validation tool, not an access restriction system. This means that while we can accurately detect disposable, temporary, or low-quality email addresses via our API and bulk checks, it's up to each platform to implement logic based on the validation results - for example, blocking temporary emails during registration.

If you tested our sign-up using a disposable address, you’re right: the system allowed it. That’s intentional - our public-facing portal doesn’t block any emails because we want users to test freely, including with temporary emails.
However, when integrated into your own product via our API, you have full control to:
- Block disposable or low-quality emails in real-time
- Prevent signups from suspicious sources
- Improve deliverability and database hygiene
In short: our detection engine works - but how it’s enforced is up to the implementation.
Let me know if you’d like a quick demo or help integrating Mailcheck to enforce stricter logic on your side.

A: When we say Mailcheck is GDPR-compliant, we're referring specifically to how our service handles data, not just the website. Here's what that looks like:

- We only process the email address that's submitted for validation — nothing more. No names, IPs, or other personal info are collected.
- Email addresses are not stored after validation. Everything is processed in real time, and we don’t keep logs of the data unless there's a specific request or agreement in place.
- The emails are used strictly for the purpose of validation, nothing else. We don’t reuse, share, or send anything to them.
- From a compliance standpoint, we operate under legitimate interest — helping people reduce bounces, protect sender reputation, and keep their email lists clean.
- Our infrastructure partners are GDPR-compliant as well. If any data ever leaves the EU, it’s covered by Standard Contractual Clauses to ensure it's handled properly.
- And of course, if someone does want to access or delete their data, we respect all GDPR rights — even though we don’t retain anything by default.
