What Verif.email checks

Valid format

First, we check that the email address format is correct. It should look like "[email protected]".

Non-random email address

We check that the address doesn't look like a random email address. For example, "[email protected]" doesn't pass the test.

Permanent email address

We check if the email address has a domain name used for temporary email addresses.

Using a webmail

We check if the email address uses a webmail like Gmail or Yahoo.

MX Records

We check that the domain has MX records. If there are none, the email address cannot receive emails and will therefore be considered invalid.

Presence of an SMTP server

This check is successful if we are able to connect to the SMTP server (indicated in the MX records).

SMTP Verification

We test the email address and see if it bounces or not, without sending an email.

Accept the entire domain (Catch-all)

We check if the server accepts all email addresses.

Why use our email tester?

To avoid sending emails to inactive addresses! Our tool allows you to verify one or more email addresses in just a few clicks and guarantee a correct bounce rate. This way, you'll no longer have to worry about the validity of your bounce rate and can focus on what matters most.

Our tool allows you to improve your marketing efforts in three ways:

Improve deliverability

Acquiring email addresses is a lot of work. You also need to ensure your online reputation. Every business that sends emails receives an online reputation score. Fake or outdated email addresses negatively impact this reputation, jeopardizing your reach with real subscribers. If your score is too low, your email is likely to end up in spam and therefore not be opened by your recipient. And since the internet never forgets, it's often very difficult to restore a healthy reputation. By ensuring the validity of your email addresses before sending your emails, you guarantee your good reputation on the web.

Improve the open rate

When your customers provide their contact information, they expect to hear from you. If they enter the wrong address, you're missing out on a relationship and a potential conversion. Additionally, some regulatory tools limit the number of emails sent. So, if you have a lot of invalid email addresses, your actual customers may not see the email you sent them. With valid email addresses, you ensure an optimal customer experience and interactions that will have a positive impact on your brand image and your financial health.

Increase your ROI

A fake email isn't just a lost opportunity to connect. With a high percentage of invalid addresses in your database, you're directly losing money. On the contrary, sending to valid addresses increases engagement rates, improves your reputation with your suppliers, and therefore leads to more conversions. By using our tool, you're directly optimizing your return on investment.

FAQ

Can I check if an email address is valid without sending an email?

Absolutely. With our email address verification tool, you can verify an email address without sending a single email. It's a significant time saver with guaranteed results!

How to check if an email address is valid?

Our email address checker makes it easy to confirm the validity of an address. Simply enter the address(es) you want to check, and we'll verify it against several criteria to establish its validity.

What is a valid email address?

A valid email address is simply one that can receive emails. For example, a subscriber may sign up for your newsletter with their work email address. The address is considered valid as long as they are still employed by the company. However, if the subscriber leaves the company, this address will disappear, making it invalid. A randomly entered email address will also be considered invalid.

Can a valid email address be rejected?

Verifications are never completely secure, but we can guarantee that over 99% of "valid" email addresses will not be rejected.

What does "accept all" or "catch-all" mean on an email address?

When performing email verification, the result may be "catch-all." Some email servers accept all email addresses for the same domain name, whether they have actually been created or not. In this case, there is no way to ensure that the verified email address actually exists and return the "catch-all" status.

Does Verif.email send an email to perform verification?

The email verifier performs validation without sending an email, connecting directly to the SMTP server. Your customers won't be bothered by a test email; we perform this verification discreetly.

What is email deliverability?

Email deliverability is the ability to deliver emails to recipients' inboxes. It's a metric marketers use to assess the likelihood of their email campaigns reaching their subscribers' inboxes, based on internet service providers, bounces, spam issues, and more. Elements that negatively impact email deliverability include sending without personalized authentication, using a single opt-in, sending from a free domain email address, using spam, and more.

What is an email blacklist?

An email blacklist is a real-time database that helps determine which emails should be considered spam. Essentially, it's a filter that determines whether an email reaches its recipient's inbox.

What is bounce rate?

A bounced email is an email that could not be delivered. More specifically, it is a delivery failure related to server or spam issues, whether permanent or temporary. Typically, it is a metric expressed as a percentage of subscribers who did not receive your message. There are two types of bounces: hard and soft. A hard bounce is due to an unreachable email address, while a soft bounce is caused by a technical issue with the destination inbox.
