ZeroBounce vs. GMass

Should you use ZeroBounce or Gmass to verify your email list? It depends on what your goal is. Below we look at the two services to better understand how they compare.

ZeroBounce or Gmass: which one’s better?

First, let’s look at the major difference between ZeroBounce and Gmass. While ZeroBounce is an email validation and deliverability platform, Gmass is a Chrome extension for sending emails. Its core service isn’t email validation – this is only a built-in feature to help you save time when you send mass cold emails.

How reliable is it? “The accuracy is very good,” Gmass states on its website. However, the company admits that Gmass is “probably not as accurate” as some of the email validation platforms out there. ZeroBounce, for instance, guarantees an accuracy of 99%.

ZeroBounce and Gmass: how does each verify emails?

Now, let’s look at what the email verification process looks like at ZeroBounce and Gmass. What kinds of risky email addresses do they detect?

At Gmass, before you send a batch of emails, the system runs your contacts through the built-in validator. If a contact comes back as invalid, the email is not sent, and that helps you avoid bounces.

Gmass’s email validation process is basic, but it can detect:

• malformed addresses

• domains that can’t accept email

• nonexistent users

ZeroBounce, on the other hand, has a greater ability to identify bad emails in your list. The email checker can spot:

• invalid emails, including malformed addresses and nonexistent users

• spam traps, which are exceptionally risky to your email deliverability

• abuse emails that belong to users with a history of reporting emails as spam

• catch-all emails, which can bounce and affect your reputation

• disposable emails that are set to last only a limited time

• role-based emails, monitored by groups of people, not individuals

• toxic domains, known for spam and bot-created addresses

Another plus is that ZeroBounce detects duplicate addresses in your list. Also, it adds missing information to your contacts, such as name, gender and location.

Can you validate emails in bulk and in real time?

Both ZeroBounce and Gmass can validate email addresses in bulk and in real time. With ZeroBounce, you can either upload your email list onto the platform or use the real-time email validation API on your signup forms. You can verify as many contacts as you need, either in bulk or in real time.

Gmass will validate your contacts on the go, right before it sends your emails. There are no limitations to how many contacts you can check. If you’d like a bulk email verifier, Gmass made one available for free. However, this web-based tool can only verify 5,000 email addresses per hour.

Both ZeroBounce and Gmass offer additional email deliverability tools at an extra charge. Some of these tools include email server and inbox placement testing, blacklist monitoring and SPF/DKIM/DMARC testing.

Is there a difference in pricing?

ZeroBounce charges $65 to check 10,000 email addresses. Gmass’s email verification is included in your monthly subscription. Prices range from $19.95 to $49.95 a month.

A ZeroBounce account comes with a few monthly perks:

• 100 free email validation

• 1 free inbox placement test

• 1 free email server test

• 1 free blacklist monitor

As for support, Gmass clearly states on its platform that it does not answer questions via phone or chat. The company uses a ticketing system. ZeroBounce offers 24/7 support via phone, email and live chat. Whether you’re a customer or not, reach out to us if you need any help. Our team is happy to assist you.
