Byteplant is a simple and effective solution for keeping contact lists clean and sustainably improving the quality of email marketing.
Pros: Using Byteplant is a no-brainer for me. I don’t want to send emails to addresses that no longer exist or are invalid. That’s why this tool is so valuable, especially for maintaining clean contact lists. The improved data quality is particularly helpful for us, as it has a direct positive impact on our sender reputation. This noticeably supports our email marketing efforts. Additionally, the interface is straightforward and easy to understand, making it quick and simple to use. Pros Great value for money Higher data quality Better sender reputation Simple, intuitive interface Useful for regular list maintenance
Cons: A minor drawback, in my view, is that the process can sometimes take quite a long time. Nevertheless, I would definitely recommend Byteplant, ideally for regular use once a month.

Pros: Needing a "live" email validation wit PHP API, Byteplant E-Mail Validator was very easy to implement thanks to good documentation and code samples. After first test, the product seems to provide quite good value for money. We especially like the timely unlimited subscription where we can subscribe an amount of verifications that is not time bound as use the tool not regularly (e.g. weekly).
Cons:

Byteplant helped me clean a large list before importing it into my CRM. The validation definitely reduced the number of bounces compared to sending without checking first. However, I had to dig into the result codes to understand the difference between “true valid” and “catch-all,” which is critical if you want to keep bounce rates under control. With clearer reporting, it would be nearly perfect.
Pros: The validation process was fast and straightforward. The report was detailed with clear result codes, which made it easy to see which emails were valid, catch-all, suspect, or invalid. I also appreciated the ability to download results with different filters (valid only, include catch-all, etc.), which gave flexibility in how to use the data.
Cons: Catch-all addresses are counted as “valid” in the totals, which can be misleading. It made me think I had more 100% safe addresses than I actually did. I would have preferred if Byteplant separated “valid deliverable” (200) from “catch-all” (207) in the summary stats, so the risk was clearer upfront.

Pros: The valuation of the email addresses came fast and in a very good quality. Especially the classification: suspect and invalid email addresses. The customer support was very helpful.
Cons: There ist really nothing so far to complaint about. The overall experience with Byteplant was very good.

It is almost correct, give me more convenience, only several domain like yahoo, gmail, hotmail needs to update with more data
Pros: It works perfectly, I like it. There are many emails in my works, sometimes I need to verify which email works, so I need to use a validator.
Cons: some domain like @yahoo.com, validator shows ok green, actually it is no valid email address, so some domain needs to care more.
Leejean Z. · Sales Manager · Automotive · July 12, 2025
Fast and easy file upload of the email list and download of the results. Information about the current interim results via email.
Pros: The results are available quickly and are presented clearly using the codes.
Cons: Payment must be made in advance and will be processed through another company.

Die Turngemeinschaft Rüsselsheim 1862 e.V. entschied sich im Oktober 2024 für die Abschaffung des Papierformulars für die Mitgliederanmeldung. Der neue Workflow wurde mit NEXT UI umgesetzt. Eine Anforderung war mit der Digitalisierung die Datenqualität grundsätzlich zu verbessern - unter Beibehaltung der DSGVO. Über die reine HTML Validierung hinaus blieb nur die eingegebene E-Mail Adresse des Antragstellers direkt online zu validieren. Hierzu wurden drei Anbieter geprüft und Byteplant konnte am Ende in den Themen einfache Implementierung, Schnelligkeit und Genauigkeit der Validierung als auch DSGVO Konformität überzeugen.
Pros: 1. Einfache Implementierung der API in NEXT UI und über Plugin in Wordpress 2. Die Geschwindigkeit der Validierung 3. DSGVO konform
Cons: Ich würde mir wünschen, dass ich in meinem Account noch eine zweite API für Developmentzwecke einrichten kann.

Walter D. · Admin · Leisure, Travel & Tourism · October 21, 2024
The results were instantaneous and allowed me to quickly identify any invalid or problematic addresses in my database. I was very pleased with the accuracy of the validation.
Pros: Overall, I found the email validation service to be extremely helpful, reliable, and cost effective. I would highly recommend it to anyone looking to clean up their email database and ensure successful email delivery.The API was easy to integrate with my app via Zapier.
Cons: The online user interface could be designed to be easier to navigate, but it's not a big deal at all.
David C. · Marketing Consultant · Automotive · March 7, 2023
Pros: Treatment speed is essential : being able to check hundred of thousands of email within a few hour is a bonus!
Cons: The buying process is a bit complicated and slows everything
Peter v. · CTO · Computer Software · February 20, 2023
EV has been extremely amazing and has saved me from getting banned by ESPs. I used to have a higher than average bounce rate but with EV, my list has stayed clean. I used to also have issues with students entering the wrong email when enrolling. That is a thing of the past now as they are unable to make payment unless the right email address is used
Pros: The integration with my wordpress site was completely seamless. Since I set it up, I have never has to do anything other than buying credit
Cons: Currently only use the email validation feature and I have absolutely no issue

Pros: I appreciate how granular the results are.

Lucas I. · Email Marketing Specialist · Marketing and Advertising · September 20, 2021
Pros: Easy to set up and get going. Does its job well.
Cons: Eventhough it is easy to use the UX could be improved.
Elias M. · Webdesigner · Design · August 5, 2021
Pros: I recently switched newsletter companies, and when exporting the email list, it had errors. This service was straightforward to use and saved me hours manually fixing data entry errors. On top of that, it verified the validity of the email addresses. This service was awesome! A serious time saver. It took very little time!
Cons: I did not find anything I did not like about it.
Vickie W. · Executive Director · Non-Profit Organization Management · July 21, 2021
Pros: Before using this software we had rather large amounts of invalid and disposeable emails in our CRM database - which really damaged our email marketing campaigns. After running our entire database through Byteplant's Email Validator, we've really managed to improve our data quality significanty.
Cons: Sometimes validations take a bit longer than expected but this does not happen often.
Bianca L. · Sales Operations · Apparel & Fashion · July 12, 2021
Since we implemented this, all email data have been improved. It adds another security level to our online platforms.
Pros: Integration is very easy to all your platforms. If email clients are important for you, this tool must be part of your basic healthy strategies.
Cons: For now, this works good for me. For now, this works good for me.
Jonathan S. · Online Tech · Leisure, Travel & Tourism · June 30, 2021
The most accurate email verification tool. I am using single email validation and bulk validation. We verify users during registration and use bulk verification when launching marketing campaigns or sending information emails to our customers. The email validator is GDPR compliant, so I don't have to worry about working with our European clients. I love how quickly it checks the email lists.
Pros: Fast work, even with large email lists Stable tool. Accuracy plays a major role for us. Great support.
Cons: Nothing comes to mind. It just works perfectly, so I don’t even think about it.
