MailBoxValidator 2026: Benefits, Features & Pricing

Helped us build more robust database of our customers and precheck new contacts. Improved our email campaigns values and deliverability.

We had to use Zapier instead of direct integration into our CRM. Not applicable to be used for every EU market seemingly by results.

Mailbox Validator (MV) is a fantastic way to ensure that the email addresses in your email marketing lists are legitimate. If you have a list of subscribers that you haven't touched in a while, Mailbox Validator allows you to reduce the number of email bounces that you get by filtering out emails that no longer exist (for example, if someone leaves a company). This ensures that your email server's IP address maintains a great sender reputation, giving your emails much better deliverability. MV is surprisingly easy to use. You just grab your list from your email marketing or marketing automation platform, run it through the software, and filter out the junk. Then re-upload the cleaned list back into your system.

While Mailbox Validator does a good job, keep in mind that won't give you a 100% cleaned list. The first time you send emails to your cleaned list, you might still have a number of bounces - in fact, you might still have a higher-than average bounce rate for your email program depending on how stale your list was. However, by running your list through MV, you will strip out the majority of bounces, ensuring that your email service provider doesn't come after you with a pitchfork. I do wish that MV formatted the data output a little better. The columns that it appends to your data file are somewhat cryptic and can, at times, be hard to know which columns I should take into consideration when determining which emails to strip out of my list. I'd like to see them make the column descriptions more user-friendly, and perhaps provide a bit more documentation to inform the user on which fields are the most important to consider when deciding whether an email should be removed from your list.

The idea is great as I mistype emails all the time. Thought was that I would validate these after entered into my software.

It is not reliable to use.

As a small business owner time itself is an uphill battle that at times seems like you will never reach the summit or reach the lushus valley of green at the basin... Well, when your goal is to inform new prospects to not just increase your own business but to help other business owners as well, email has been a major marketing channel because let's face it, who still uses stamps anymore? When I was faced with over 45,000 emails accumulating over the years, it seems like an impossible challenge that would take approximately two and a half months to complete and that's working full days, we simply couldn't afford that much time away from the day to day business all to maintain a balance ourselves. We tried a handful of email valuation companies far and wide and none of them seemed reliable and overpriced to say the least, then we spoke with MailBoxValidators and we not only meet some genuine people but they got out job done in no time and it value outweighed the cost ten-fold. Thank you

None, stellar business and we will be a life long customer. Maybe the only suggestion would be to act a little meaner? Because they are just way to nice and genuine it felt like we've been doing business for decaded.

Easy to remove correct email address. amazing software to remove email id.

most helpful software to remove email id

Checks not only the DNS like most other similar services do, but checks the mailserver too. Also pretty detailled response and not just "good" or "bad" like most others do.

The documenation is quite good in general but I would like to get more information about the response parameters. eg. what are the high_risk_keywords in is_high_risk response or how the reputation score gets calculated.

Quick and easy to use. Highly recommended.

Perhaps the prices and looking for more featured offers

It helps millions of people find the best business softwar

none so far. I love all the software´s features.

ease of use. good API call response time.

you should have a more professional looking website and user dashboard.

I've been using Mailbox Validator for a few months and think it's great! I use a webmail and email client, so MBV has been helpful keep things organized.

It's sometimes difficult to use MBV without integration with our newsletter-sending client; I have to transfer the data between multiple programs.
