What Verif.email checks

Valid format

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

Non-random email address

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

Permanent e-mail address

We check whether the e-mail address has a domain name used for temporary e-mail addresses.

Using webmail

We check whether the e-mail address uses webmail such as Gmail or Yahoo.

MX recordings

We check that the domain contains MX records. If it doesn't, the e-mail address can't receive e-mails and is therefore 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 check

We test the e-mail address and see whether or not it bounces back, without sending an e-mail.

Accept all domains (Catch-all)

We check whether the server accepts all e-mail addresses.

Why use our mail tester?

To avoid sending emails to inactive addresses! With just a few clicks, our tool enables you to check one or more e-mail addresses and guarantee a correct bounce rate. So you don't have to worry about the validity of your bounce rate, and you can concentrate on the essentials.

Our tool enables you to improve your marketing actions in three ways:

Improve deliverability

Acquiring e-mail addresses takes a lot of work. You also need to be sure of your online reputation. Every company that sends emails gets an online score corresponding to its reputation. False or out-of-date e-mail addresses have a negative impact on this reputation, and therefore jeopardize your impact on real subscribers. If your score is too low, there's a high risk that your e-mail will be spammed and not opened by the recipient. And since the Internet never forgets, it's often very difficult to recover an intact reputation. By ensuring the validity of your e-mail addresses before you send your e-mails, you guarantee your good reputation on the web.

Improve open rate

When your consumers provide their contact details, they expect to hear from you. If they enter the wrong address, you miss out on a relationship and potential conversion. What's more, some regulation tools limit the number of mailings. So if you have a lot of invalid email addresses, your real customers may not see the mail you've sent them. With valid e-mail addresses, you ensure an optimal customer experience, and exchanges that will have a positive impact on your brand's image and your financial health.

Increase your ROI

A false e-mail isn't just a lost connection. 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 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 whether an e-mail address is valid without sending an e-mail?

Absolutely. With our e-mail address verification tool, you can check an e-mail address without sending a single e-mail. It saves you a lot of time, and the result is guaranteed!

How can I check whether an e-mail address is valid?

Our e-mail address checker makes it easy to confirm the validity of an address. Simply enter the address(es) you wish to verify, and we'll take care of confirming several criteria to establish their validity.

What is a valid e-mail address?

A valid e-mail address is simply an address that can receive e-mails. For example, a subscriber can subscribe to your newsletter using his or her professional e-mail address. The address is considered valid as long as the subscriber is still employed by the company. However, if the subscriber leaves the company, this address will disappear, rendering it invalid. A randomly entered e-mail address will also be considered invalid.

Can a valid e-mail address be rejected?

Checks are never totally secure, but we can guarantee that over 99% of "valid" e-mail addresses will not be rejected.

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

When you run an e-mail address check, the result may be "catch-all". Some e-mail servers accept all e-mail addresses of the same domain name, whether or not they have actually been created. In this case, we can't be sure that the verified e-mail address actually exists and return the "accept all" status.

Does Verif.email send a verification email?

The e-mail verifier performs validation without sending an e-mail, by connecting directly to the SMTP server. So your customers won't be disturbed by a test e-mail, because we carry out the check discreetly.

What is email deliverability?

Email deliverability is the ability to deliver emails to recipients' inboxes. It's an indicator that marketers use to assess the likelihood of their email campaigns reaching subscribers' inboxes, depending on ISPs, bounces, spam issues etc. Elements that affect the deliverability of a mailing include sending without personalized authentication, using a single opt-in, sending from a free domain e-mail address, using spam...

What is an e-mail blacklist?

The e-mail blacklist is a real-time database used to decide which e-mails should be considered spam. Essentially, it's a filter that determines whether or not an e-mail reaches the recipient's inbox.

What is the bounce rate?

A bounced e-mail is an e-mail that has failed to be delivered. More precisely, it's a delivery failure linked to server or spam problems, whether permanent or temporary. In general, it's a measure expressed as a percentage of subscribers who didn't receive your message. There are two types of bounce: hard and soft. Hard bounce is caused by the inaccessibility of an e-mail address, while soft bounce is caused by a technical problem in the destination inbox.
