MillionVerifier is a platform that offers a single email checker, bulk email validation and a real-time email verifier via their API. Their service leans exclusively on checking emails.
ZeroBounce offers the same features, including all the various email verification methods MillionVerifier offers. However, they offer more strategic tools and advantages that will help boost your email deliverabilityⓘ and email marketing performance.
Compared to MillionVerifier, ZeroBounce offers
Let's look at everything ZeroBounce offers above compared to its competitors.
A clean email listⓘ is invaluable for email marketing, but gaining more data about your subscribers allows you to make smarter decisions for your campaigns.
MillionVerifier simply verifies the status of your emails. You select the email types you want to detect and get your report.
ZeroBounce enhances your email list cleaningⓘ report by appending essential data points when possible regarding each contact. This provides email data, including domain, subdomain, IP, and mx exchange information.
But, ZeroBounce also appends vital social data, including the user's name, location, and gender, when available.
You can use this data to assist with your email list segmentation after you find out which email contacts are valid. Segmenting a list with the right data points will help you improve your performance and boost your email marketing ROI.
Your brand's email cleaner is only as good as it is accurate.
MillionVerifier and ZeroBounce can provide 99.6% accurate results using the single email checker, bulk email list verification, or the automated email verification API. Regarding reliability, both brands promise to live up to their promise regarding what they can identify.
However, ZeroBounce's promise extends to all those additional email types that MillionVerifier will not detect. ZeroBounce's guarantee also allows you to successfully identify hard-to-detect email types like spam traps and abuse emails.
MillionVerifier backs up its 99.6% accuracy with a money-back guarantee. However, they falsely report that they're the only brand offering such a promise.
ZeroBounce also offers a no-questions-asked money-back guarantee. ZeroBounce aims to help improve your email deliverabilityⓘ and achieve a safe email bounce rateⓘ of 2% or lower, not the 4% MillionVerifier suggests on their website.
MillionVerifier, like many email verifiers, can only identify a catch-all or accept-all email domain.
Brands use these emails to cast a wide net and catch incoming emails sent to invalid users on their domain. Someone can then trash unwanted messages and redirect others to the ideal point of contact.
Many email verifiers like MillionVerifier only tag these emails as risky and recommend them for deletion. While this is generally sound advice to help your email engagement, it's not always accurate. You need a better solution to understand how valuable a catch-all email might be.
ZeroBounce offers additional Email Scoring. Utilizing artificial intelligence, it detects activity levels of an email address, with 0 representing low or unknown engagement and 10 indicating high levels of inbox activity.
This insight lets your company make more informed decisions about which emails to keep and which to delete. Remember, every email lead you obtain has a cost, and depending on your average bounce rate, it can be worth pursuing a catch-all to net a potential conversion.
In email marketing, more data is imperative. ZeroBounce gives you the most in-depth insights possible to help you improve your campaign performance.
Anytime you choose a technical solution for your company, you must know it's reliable. Even with an excellent platform, user issues can pop up. If you have an important deadline, you must know that help can be there quickly.
MillionVerifier only offers potential support via a live chat prompt on their site. You must enter an email address and wait for someone to respond later.
