18. Verifalia

Best Alternative to Email Hippo for Validating Yahoo Mailboxes.

Verifalia is the Best Alternative to Email Hippo for Validating Yahoo Mailboxes

Verifalia is a trusty web-based email validation service. It performs a full hygiene check and cleansing procedure via DNS validation and MX records lookup. It also checks for SMTP and mailbox connection availability, ISP-specific syntax, advanced syntax according to IETF standards, role accounts, disposable email addresses, and catch-all testing, and international domain names.

Verifalia is also able to validate Yahoo Mailboxes, which makes it a great alternative to Email Hippo. This is huge as most providers are unable to offer validation for Yahoo mail because of Yahoo’s particularly strict security measures.

Moreover, Verifalia comes with anti-greylisting technology. It can detect temporary mailbox unavailability and retry addresses several times at specific intervals to avoid greylisting. And with the HTTPS-based RESTful APIs, you can automate validations in mere minutes.


Verifalia Pricing Plan

You get 125 free validations per day on the free plan. If you need more than that, you’ll have to shell out anywhere between $9/month for 250 verifications per day and $499/month for 25,000 verifications per day — that is, if you opt for annual billing.


  • You get 125 validations per day for free
  • The free plan may be good enough for most people
  • Can validate Yahoo emails


  • The paid plans are a bit expensive
  • No native integrations
  • Weak customer support
  • Poor turnaround time

Why Use Email Verification and Validation Tools?

Astonishingly, only 10% of email addresses collected are accurate. And 60% of consumers intentionally provide incorrect information when submitting personal details online.

Read that again.

Email is still the number one way to get customers. Real customers start with real emails. And the only way to ensure that the customer data you collect is of the best quality is email validation. Email verification improves the overall effectiveness of your email marketing campaigns, fraud prevention efforts, and protects your sender reputation.

There are four main benefits to using email verification tools:

1. Accurate Analytic Data

With a validated list, you get reliable data that you can use to improve the performance of your email marketing. You’ll know for sure that your open and click-through rates are accurate and not artificially deflated by invalid emails. You can run A/B tests that more accurately portray the reactions of real customers. And you can spend less on your email marketing. Or spend on new, real customers.

2. Increased Open Rates

It may seem like people are just not opening your emails. But it may also be that your content isn’t the problem; the invalid emails in your list just might be the problem. By verifying your emails list, you increase the chances of your email going to a real person that wants to see your content.

3. Improved Email Marketing ROI

With a clean email list, you get into the inbox of customers you want. This gives your investment in email marketing a chance to get to work immediately, converting readers into long-term customers.

4. Improves Sender Reputation

In real life, having a great reputation in public means that you could get more customers via word-of-mouth. The same applies to your email reputation. ISPs reward you with a higher email reputation when your emails go to real email addresses, and they punish you when the reverse is the case. With a higher score, there’s a higher chance that your messages will stay out of the spam box and get in front of your customers.

Choosing the Right Email Verification Tool

Our final recommendations:

  • The best overall email validation platform is Hunter.
  • If you want email campaign automation and email verification in one suite, check out Snov.
  • NeverBounce is your best bet if speed is of the essence.
  • For the security conscious, Truemail.io is it.
  • And if you need to verify Yahoo Mail addresses, Email Hippo will fit the bill perfectly.
