Email Validation Services
Email validation, or email validation service, is an integral part of every email platform, as email addresses are the lifeblood of an email marketing campaign. Therefore, it is only logical that you will validate email addresses when sending out email marketing or promotional emails to a list of email subscribers. When using a standard email service, validating email addresses can prove tricky because of the various differences between different email platforms. Depending on what platform you use, the email validation process varies. You can learn more about email validation on this page.
The first step in any email validation service is to run a basic check to the "from" field. This step is called "catch-all" or "catch-all verification". In a typical email service, this step verifies whether the full name of the sender is indeed the sender of the emails. Some email services include a generic "from" field, which might not return all the information needed by the customer, while other email platforms include a customized "from" field with various parameters for the customer to enter into. If the email service is unable to successfully match the "from" name of the sender with the email address in the "to" field, then there are a few options available for validate email addresses. For example, some email platforms allow the use of wildcards to identify IP addresses, and these can be matched against IP addresses using regular expressions.
The second step in the validation process involves accessing the "data points" of the domain or website being validated. Data points are logical points in the domain structure where the email address is associated with. There are two logical data points in a domain, they are named SERP (subject path part) and OU (outbound path part). The email validation service platform will determine which domain part corresponds with the email address being validated against. In some email validation services, these data points are automatically extracted from the domain structure. This process of automatic extraction can potentially lead to inaccurate data points, especially if the domain name used does not contain any spaces or slashes.
The next step in the email validation service may look up the expiration date for the domain that is being passed against. This is particularly important in cases where the domain is registered but the owner is still active. Expiration dates are usually hard to verify due to the slowness of domain name servers. This can lead to invalid email addresses. Therefore, it is advisable to check whether the expiration date is set manually by the service or has been set by the registrar. Failure to set the expiration date will result in users getting a stale email address when they try to log in after years-past.

Another aspect of email validation service that is often overlooked is the ability to look up other email addresses associated with the domain being validated. It is possible to find email addresses that are associated with domain names that have been registered but are no longer active. If users tried to log in under a different name, they would still be unable to access the site. This is because the information provided by the email service would indicate that the user is attempting to access content that is no longer available.
One last point to be made is that using a mail invalidator could affect the credibility of the site. Users would not feel comfortable using the site if there are unreliable email addresses being passed against. Therefore, this aspect of the validation process should be taken into consideration and should be done properly. Mail validators are generally reliable but not 100% accurate. Therefore, it is important that you choose a reputable mail validator. Check out this related post to get more enlightened on the topic:
