Emme tarkista arvosteluissa esitettyjen väitteiden paikkansapitävyyttä, sillä arvostelut ovat arvostelijoiden omia mielipiteitä. Arvostelu voi kuitenkin saada Varmennettu-merkinnän, jos pystymme todentamaan, että arvostelun kirjoittaja on asioinut yrityksen kanssa. Lue lisää
Alustan luotettavuuden varmistamiseksi kaikkien arvostelujen – varmennettujen ja varmentamattomien – on läpäistävä automaattinen seulonta, joka on käynnissä kellon ympäri. Järjestelmä tunnistaa ja poistaa ohjeistustemme vastaisen sisällön – myös arvostelut, jotka eivät perustu aitoon asiointiin. Tiedostamme, että asiattomia arvosteluja saattaa tästä huolimatta päästä läpi. Voit tehdä meille ilmoituksen mistä tahansa arvostelusta, jonka uskot jääneen meiltä huomaamatta. Lue lisää

Hello,
Thank you for your feedback. We’re glad to hear that you appreciate the quality of our service and our pricing this is something we continuously strive to maintain.
Regarding your comment about the API, we take it very seriously. Our API is currently used by many customers, including integrations with tools like Clay, and its implementation is generally simple and straightforward. It does not require advanced technical skills: you simply need to use an HTTP API module, enter your API key, and map the email column as a parameter for verification.
That said, we understand that issues can arise in specific situations, and we would be happy to review your case in detail to assist you.
However, after verification, we could not find any customer account under your name in our database, nor any support request related to your situation. Additionally, our monitoring systems confirm that our service remained fully operational and uninterrupted during the period mentioned, with no major incidents.
These elements suggest that this review may not reflect a genuine experience with our platform. We would like to remind you that, in accordance with applicable laws, publishing false or misleading reviews may lead to legal action, and we reserve the right to initiate appropriate proceedings if necessary. Such statements may also engage the responsibility of their author.
Our priority remains transparency and customer satisfaction. If you have indeed used our service, we invite you to contact us via our contact form and specify the name under which you subscribed, so we can understand why your setup is not working and provide appropriate assistance.
Otherwise, we kindly ask you to reconsider or remove this review to ensure accurate information for all users.
Finally, if this review is part of an attempt to destabilize us on behalf of a competitor, we did not expect to generate such interest so quickly.
Best regards,
The MailTester Ninja Team ❤️

I purchased the most expensive package from Ninja Mail Tester, expecting reliable service, but it has been an absolute disaster. The servers seem to be constantly down, and despite waiting almost the entire day, nothing has worked. I’ve tried reaching out, but there’s been no progress or update.
I expected better service for the price, but it’s been nothing but a waste of time and money. Extremely frustrated with the lack of functionality and support. Definitely not worth the cost—look elsewhere for a more dependable email testing solution.

I have tried over 5 email verifiers, but most of them fail at scale. Adopting MailTester has been one of the best decisions for me- the bounce rate just vanished.

Trustpilot-kokemus
Kuka tahansa voi kirjoittaa Trustpilot-arvostelun. Arvostelun kirjoittajalla on oikeus muokata tai poistaa niitä milloin tahansa, ja ne näkyvät niin kauan kuin tili on aktiivinen.
Yritykset voivat pyytää arvosteluja automaattisten kutsujen kautta. Varmennetuksi merkityt arvostelut kertovat aidoista kokemuksista.
Lue lisää muunlaisista arvosteluista.
Käytämme omistautuneita ihmisiä ja älykästä teknologiaa alustamme turvaamiseen. Lue lisää siitä, miten torjumme väärennettyjä arvosteluja.
Tutustu Trustpilotin arviointiprosessiin.
Varmennus auttaa takaamaan, että Trustpilotissa lukemasi arvostelut ovat todellisten henkilöiden kirjoittamia.
Kannustimien tarjoaminen arvosteluille tai arvostelujen pyytäminen valikoivasti voi vääristää TrustScore-tulosta, mikä on sääntöjemme vastaista.
