Using a valid email list is essential to landing in the inbox. Below, we look at how ZeroBounce and Sendgrid compare and which one is the better email validator for you.

ZeroBounce vs. Sendgrid: which one’s better?

When your bounce rate is high and your open rates are low, finding a reliable email verifier is critical. With so many options, how will you make the right choice?

We created this comparison to help you decide between ZeroBounce and Sendgrid.

ZeroBounce’s No. 1 focus is email verification and deliverability. The platform provides you with a variety of tools to help you arrive in your customers’ inboxes.

At ZeroBounce, you can choose between:

• a bulk email verification service that allows you to clean your existing email list

• a real-time email validation API that verifies emails on the go, before they subscribe to your list

• a bulk email validation API for those of you who want to automate bulk email cleaning

Sendgrid’s email validation service works differently. The company offers an API for email validation. However, there’s a limitation here: you can only activate the API when you start using Sendgrid’s email delivery service. Furthermore, the API is available only for Pro and Premier plans.

What risky emails do ZeroBounce and Sendgrid detect?

Next, we compared email validation features to see what type of unwanted email addresses the two email checkers can spot.

Both ZeroBounce and Sendgrid can detect invalid, disposable, and role-based email addresses. Unlike Sendgrid, ZeroBounce can also identify:

• spam traps, designed with the sole purpose of attracting and blocking spammers

• catch-all emails, which have a high bounce probability and can affect your sender reputation

• abuse emails that belong to known complainers

These kinds of email contacts can jeopardize your email deliverability, so detecting and removing them makes a difference. Sendgrid doesn’t disclose any information about detecting spam traps, catch-all, or abuse emails.

Moreover, the company doesn’t state whether it removes duplicate email addresses. ZeroBounce does this automatically, at no extra cost.

What about email list enhancement?

Another useful feature ZeroBounce offers at no extra charge is the appending of missing info to your list. Where available, our service adds your subscribers’ location, gender, names, and IP to help you better segment your contacts.

Sendgrid does not offer this benefit, but like ZeroBounce, it provides a few email deliverability tools, such as spam testing and blacklist monitoring.

As for pricing, the difference is significant. It costs only $80 to validate 10,000 email addresses with ZeroBounce, while Sendgrid charges $100. There’s no money-back guarantee with Sendgrid and the company doesn’t disclose the accuracy of its email validator. ZeroBounce guarantees 99% accurate results.

That’s not all: as opposed to Sendgrid, ZeroBounce provides round-the-clock support. Whether you’re a customer or not, you can reach out to us anytime, via live chat, email, or phone, and get the help you need. Sendgrid, on the other hand, gives you 24/7 support only if you have an account.
