Email Validation a Measure Paramount to a Healthy Mailing List
E-mail validation definition:
Mailing list validation or verification refers to checking whether the e-mail address is valid and can be delivered without sending any test e-mails. This method contributes to fewer hard and soft bounces, which helps avoid spam traps, and results in the higher overall performance of your e-mail campaigns.
E-mail validation typically encompasses the following three steps:
- Formatting and syntax check:
The primary step consists of validating the e-mail addresses against recognized e-mail format standards and detective work and spelling errors in each (before an @ symbol) and domain (after an @ logo) parts of an e-mail address: any spaces and invalid characters, missing “at” sign, and so on.
- Domain and server verification:
In the correct syntax and format, the verification goes more checking if the DNS is valid and active and if the mail money handler (MX) record exists and may receive e-mails.
- Mailbox confirmation:
The final step serves to verify if the particular mailbox exists and isn't full. This can be typically done through the SMTP protocol. The e-mail friend tool pings the precise e-mail address with EHLO or HELO message and waits for the e-mail server's response. If the latter comes, the e-mail address is valid and active.
Types of e-mail verifiers:
There are two styles of e-mail verification solutions that are software and saas. The software may be a downloadable tool for e-mail validation that you will install on your pc. In contrast, SaaS-based. Therefore, solutions are obtainable online, so you'll be able to launch them anytime from any device.Now that we all know the distinction between the two styles of e-mail verifiers let’s see each's advantages and disadvantages.
Pricing:
Desktop e-mail verifiers are socheaper than you have to pay one time to induce an authorized copy of the program and use it to scan unlimited lists of the e-mails. With online-based solutions, users either obtain a monthly subscription or acquire a range of verifications or a selected number of e-mails they will check per month.
Multiple users:
If you decide on desktop verifiers, you'll be able to access it solely from the pc it had been put in and designed on. However, with saas-based solutions, matters are different: you'll be able to log in from any device and access one account by multiple users. All the same, some online verifiers enable limiting access to specific information science addresses.
Data security:
On the one hand, after you are employing a desktop app on one device, your mailing list is stored on your pc. Therefore it's under your management. You don’t have to be compelled to worry a lot about information leaks, of course, keeping in mind about spyware threats, however,the effort that to your firewall. On the other hand, if the pc crashes, the information is lost. Therefore you ought to continually have a backup and build reserve copies keep elsewhere daily.
Meanwhile, after you verify your mailing lists online, the information is kept in your new account. Therefore no viruses or constituent failures will damage it. Any online service will suffer information leaks or system glitches simultaneously; thus, creating a reserve repetition should be often worn out in this case.
IP address safety:
Despite all the deserves, the reality is that excessive use of desktop verifiers puts your IP reputation in danger. E-mail servers might take multiple verification requests for spam attacks and come false-positive or false-negative verification statuses. Within the worst-case state of affairs, your information science might get blacklisted by anti-spam databases. Of course, there'sa choice to mask the important information science with a proxy, but again, this involves further efforts and price to every verified e-mail.

How to stop faulty e-mails from moving into your listing:
Use double opt-in:
Typos typically occur once filling within the net kind subscribers accidentally hit a wrong or an additional key. Double opt-in filters incorrect data: 1st of all, a subscriber enters their e-mail address into the subscription form; second, they need to log in to their e-mail account, open the confirmation message and click on a registration link to substantiate the subscription:
If the subscriber ab initio keys during a wrong address, they'll merely not receive a confirmation e-mail.
Track delivery problems:
Make it a habit to envision statistics on your e-mail campaigns to deal with bounces of invalid or non-existent e-mails. For example, it provides close statistics concerning delivery errors.
Segment and activate your subscribers:
Divide your subscribers into many parts reckoning on after they joined your mailing list:
- 1-6 months ago,
- 6-12 months ago,
- More than one year passed.
After that, compose a reactivation schedule. Send a re-engagement campaign to the primary cluster, then try and activate the second cluster. Finally, combining the subscribers from the third cluster with those users from the primary and second World Health Organization teams has more established your reactivation e-mails.
