E-mail checker

It is sometimes needed to know for sure, whether the email address that you have is valid. The cases for it may be personal mailing, writing a business letter to someone with a proposal of your product or service, or during the marketing campaigns. Nobody wants to see as their letters are sent into nothingness, and here is where e-mail checkers become really useful as they can verify the email address.

The essence of an email checker

There are many email verification services that may do the check for you. Having varying technical and visual implementation and major differences in email verifying, they all persuade the same goal: to let people know whether this or that email address they’re holding is valid. The ‘validity’ of it may largely vary amongst the checkers, as some of them only tell you basics like is it ok or bad (as it is the case with email-checker.net), while the others spanned the data results much farther than that, giving so many information that some of it is abundant for a regular user (this is the case with verifalia.com). Below, we are considering the differences between the mentioned just to make you informed about the peculiarities of their work. If you happen to find more checkers online on your own – you can do the same comparison to choose the best one for your goals. And remember that it is strongly advisable to use at least 3-4 of them at once to make the email validation of the same pool of addresses, as the results can vary from one pole to another.

How email checkers work

Just to show you the real-life difference on the answer to the question ‘how to check if the email is valid,’ in the case with all above-mentioned online email checkers, we have made 7 checks for each of them using different domains that are hosted in varying countries of the world. Some domains are known worldwide, while some others are regional. All addresses exist for real and to do the check, we’ve taken some e-mails from our working correspondence, personal accounts, and googled a few. In a whole, we have done over 50 checks (7 domains multiply at 8 checkers). We submit the results below: Some of the sites ask for numerous verifications and validations before plunging directly into work (proving you’re not a robot, turning off your AdBlock and so on, and may be limited to a few daily checks from the same IP address The other sites specifically designed to provide a bulky type of verification – it means that you may check much more than 1 email at once thanks to a form of insertion of multiple emails. But as they may not give the results on the same page, so after each one completed piece, you have to return to the main form. They also may require Google’s Captcha verification (which sometimes works badly pretty so you have to constantly refresh the destination page to test email.

Why one wants to check email online

We can highlight three main reasons why would one want to use the email checkers: I. In personal correspondence, when you receive an email from a new person, before wasting your time on writing anything to him or her, it is advisable to make a simple check. II. When you are running the business connected to constant lettering with your clientele, an alive database is what’s most sought-after by marketers. Actually, more than 5 out of 10 marketers in various fields tell that having a verified database would economize them up to 80% of the budget for sending out the letters, as it is considered that around 80% of all email addresses are dummies. When you are gathering emails on landing pages or in other places in exchange for some tasty piece of anything (discount, subscription, try-and-buy product or something akin), you want to make sure you’re gathering really existing email address in order to be capable of sending some commercial offers and discount proposals to this person in the future. Despite the fact that almost everyone sends a verification letter on the left email, a part of them remains unproven, another part is one-day automatically created e-boxes, and only some part is alive. Also, take into account the factor of time – data gets outdated eventually. III. You send letters occasionally only to make your clients not forget about you and maybe give them congrats with a birthday or another holiday.

What are the benefits of using an email address checker?

1. A bigger number of your letters reaches the destination.
2. Being up-to-date: if you strongly rely on your database expecting for an outcome, refreshing it before a mailing campaign is a must.
3. Having more details about the holders of emails. You may find the connected data: social networks’ profiles, other online presence – as an additional work that you can do not with the entire database but with verified pieces.
4. Saving time, money, efforts – to everyone involved.

How the procedure of checking email works

First, there is a connection to the email domain on DNS to verify if such exists. Then, there is a sequence of technical commands to know as much information about the specific address as possible. Based on the result of retrieving information, the outcome is generated: _ existence of DNS _ syntax correctness _ is domain part internationalized or not _ does it support IPv4 and IPv6 _ disposable email address validation _ what kind of provider is it – free or paid _ DNS records existence _ is there any honeypot hidden _ SMTP server validation _ catch-all validation.

FAQ about email tester

1. Is there any API for developers? That depends on the site. Those ones that are limited to a few checks in a day usually have something for wholesale clients or separate apps, which definitely have API. You have to search for that information on a specific site.
2. Is there a possibility to make checks of more than 1 email at a time? A number of sites actually provide that possibility. Some of them even do it for free – like it is the case with leopathu.com. If it is not directly available at the site for free, then it may be a separate application or a paid access.
3. Is an owner of an address gets a notice about being checked? No, you can safely run your checks and nobody will be notified.
4. Is data stored after being checked? It completely depends on the site you use. Some of them specifically say at the page that they do not store info or it is deleted after a while (hours or days that are usually required to keep a short history of your checks). If they do store it for a while, it may differ for the free checks and paid ones – as during the paid check you may need a longer history to be available. Some sites specifically replenish their databases with the collected email addresses and brag about it as a search advantage. However, if you are afraid about the safety of the checked emails and non-inclusion of them into any spam databases, it is unlikely that any verification site can guarantee you that for sure.
5. Is ‘verified’ email good enough to send e-mails? Various sites offer differing technical information about the status of the mailbox. Besides, in order to shorten the description of the received data, we’ve sometimes shrunken the description of what are the outcomes but on this or that site, the description is far bigger. So there may be different grades of ‘good’ notion – for instance, some emails have IPv4 and don’t have IPv6. They may be ‘good’ but with a bad syntax (however, we don’t think this situation is possible). They may be included in the spam bases or be disposable addresses. Sometimes the domain is good but the specific address is unknown or can’t be checked. So depending on what you call ‘good’, you may have your feeling of whether it is right to do mailing to a specific address.
6. Why there is such a big difference in check results? We also wonder so. It seems like if each individual site is developed by a different person with their approach, this approach may not work in all times, the technical capabilities of checking may be universally working or not and they may be up-to-date or outdated. There is no guarantee that the service you use is actually professional and 100% trustworthy.
