Small-Business (50 or fewer emp.) 6/4/2019 "We use it mainly for the API, which has been integrated into our systems and is working very well." 3/5 What do you like best about MailboxValidator? I really like Mailboxvalidator because it provides a disposable email API that checks if an email is from a disposable email provider and returns the results in JSON or XML format, it also checks and cleans up my email list. It connects to the mail server and checks if the mailbox exists or not and reduces the rebound rate and cost them. Review collected by and hosted on G2.com. What do you dislike about MailboxValidator? What I dislike about this tool is that we repeatedly tried to verify a large list and it did not leave us. But in other functions it is surprisingly easy to use. It simply offers us a shot of my email list or the marketing automation platform, runs it through the software and filters the garbage. Then reload the clean list in your system. Review collected by and hosted on G2.com. Recommendations to others considering MailboxValidator: I recommend MailboxValidator as it has a fantastic way of ensuring that the email addresses in your email marketing lists are legitimate, likewise if I have a list of subscribers that you have not touched for a while, the mailbox validator allows you to reduce the amount of email messages you receive by filtering emails that no longer exist. Review collected by and hosted on G2.com. What problems is MailboxValidator solving and how is that benefiting you? The validation of the email addresses, usually had many important contacts, but the email addresses were not validated, since the data was old. But it helped me a lot in terms of validating those contacts. We love the number of excellent functions that range from syntax validation to MX record validation, and together with the simplicity and security of the API, this is possibly one of the best products of this type.

MailboxValidator allows us to identify the correct emails and verify whether or not the emails we have will bounce or get through successfully. By doing this, we minimize our spam rate and also prevent ourselves from being targeted as a spam email address for future emails we send to other prospects and clients. Review collected by and hosted on G2.com. What do you dislike about MailboxValidator? I dislike that some of the validation is off, and there is not 100% certainty. Several other email validating companies and platforms have this same issue, so I dislike this in regards to all companies who do the validating. The bounce rate will still be lower than if we chose not to use an email validator service, however; the question is whether or not it is worth the price. Review collected by and hosted on G2.com. Recommendations to others considering MailboxValidator: Identify if the price is worth the number of emails you need to check for verification. Review collected by and hosted on G2.com. What problems is MailboxValidator solving and how is that benefiting you? I used MailboxValidator for the purpose of verifying emails to limit the number of emails that bounced or were noted as spam. The benefits were that the number of emails that bounced dropped. Also, the pricing is not as high as some of the other companies that we trialed out, and the platform is simple and worthwhile for specific use cases. It fit our needs, but we discovered that the email verification for bounced emails was not needed as much since we found our niche market and no longer needed a service for this.
