What is an email validation and verification API?
Email validation and verification API is different from the email verification described above.
Email validation with an API goes much further than simply confirming the legitimacy and consent of the person and email account. This goes into the software and programmed protocols on your website.
You can create your protocols to specify the requirements from your website visitors when they sign up.
However, before we get into that, let’s discuss what an API is, how it works, and why you might want it involved in the validation process on your website.
Definition of an API
To begin to understand what an email validation and verification API is, you must first understand what an API is.
An API is an “Application Program Interface” that works on a set of routines, protocols, and rules to create software applications. APIs create the specifics for how all the components of software work together and interact.
APIs allow communication from two different applications or information centers to send messages. Think about the request you make when you click a link online.
You request information from the link, and an API takes that request in the form of a message to another application or information center where it receives the response message and returns it to your screen.
How an API Works in Email Validation
An API in an email verification or validation software can work in multiple ways.
For starters, an email verification API software can help ensure that the email accounts that people are signing up with are the types of email accounts you want to have on your email list.
For example, you can set up your API software to detect common or possible misspellings when the visitors type in their emails. The visitor’s email may be misspelled in the domain sector, and an email verification API can alert the website visitor that there is a possible misspelling.
These misspellings could be email@example.com instead of @gmail.com. It is very important to catch these domain errors, otherwise, the emails will not get delivered to the account and get bounced back to the sender.
Here are some common issues found while inputting email addresses, and how your API can detect and alert visitors to these issues.
Invalid email address
This is a very common issue, where the visitor who is signing up with their email misspells the domain or forgets the “@” symbol. Submitting an email with an improper domain or without the symbol is considered an invalid email.
An API with the programing to detect this will alert the visitor with a message, asking them to double-check the spelling of their email address.
Corporate and personal email addresses
If you would like to fine-tune the type of emails that can sign up for your newsletter or create an account on your website, you can program your email validation API to detect when a different type of email is being used to sign up.
If you want only corporate or business emails, you can program your API to search the “free_email” property on the API to check for “free.”
On the other hand, if you only want personal email addresses to be on the email list of your website, then you can program your API software to search the “sub-status” property for “role_based.”
Both of these programs will alert the person inputting the email that they should use a different account than the one they are currently using to sign up.
Some website owners do not care whether the email accounts are personal or corporate, but some people tend to read their personal or business emails more than the other, and prefer to have all professional or personal accounts.
Fraudulent email accounts
If you seem to be getting nothing but fraud email accounts signing up on your website, you may want to look into having your email validation API run “domain_age_days” which tells the server how many days the email account has been active for.
Typically, fraudulent email accounts or “bots” have brand-new email accounts that have just been made for this purpose. You can have the API program refuse emails that have just been created as a security measure, and to avoid sending emails to no one.

How to use an email validation and verification API
Email validation and verification are simple to use and explore. If you want to explore some API technology for free, on multiple topics, check out Abstract: Automate anything with Abstract APIs to explore the world of API.
How you can use the information, properties, and features of your API system is fairly simple.
First things first, you will need to make sure you understand what your API system is programmed to do, otherwise, you may be looking for how many duplicate emails were removed but that function is not a part of your API software program.
When your API is working on-site at your web page, you will not receive information each time it catches something. You would probably go crazy if that was the case, considering how many people accidentally misspell their emails.
Your API will detect the programs and features that you have set for it to check for, like personal emails or invalid domains. Some API programs check for SMTP protocol, to make sure that the email account has a legit mailbox and inbox where the emails can be received.
Your API can simply connect with your web page through a domain that is secured, for example, your ISP.
Steps to setting up an email verification and validation API
Here are the steps that most (not all,) API software programs follow to connect to your web page and beginning to work.
You may feel worried if you are not the greatest at computers, but please do not. This is a simple process if you follow the steps correctly.
Check to see if the API software you select has special steps on how to connect your web page to the API before you begin.
The first thing you will need to do is select and program your API. Whichever API software you choose to use will have instructions and walk-throughs on how to program and set-up your API software.
Once you have your API software prepared, you will be ready to begin the connection process.
Create your email template responses to an invalid or incompatible email address when they are sent into the API on your web page.
These are those little messages that show up when you have misspelled an email on a domain, that lets you know to correct it.
Make sure that all aspects of your API are the way you want them to perform and present on your web page
The third step is to verify your service. Confirm with the API software provider and confirm your final API software product.
On the API provider’s web page, there will be information on how to perform the connection between your new API software and your web page.
Follow their instructions exactly, making sure to double-check everything that you do. This is the most important part of getting your new API software to your web page.
Once you have followed the instructions given by your API software provider, you should have your API connected to your web page.
Now is the fun part!
Check to make sure that the connection was successful by going to the email input box and typing in a misspelled email, or make up an email with an incorrect or unacceptable domain.
If your web page refuses to accept the email, then congratulations! Your connection was successful and your API software is working properly.
If your web page allows it to enter the CRM, then you may have missed a step along the way. Try to retrace the instructions given by your API software provider and see if you can spot the step you skipped.
If you find the issue, but cannot fix it, it is suggested that you contact the customer support branch of the API company, and have them walk you through the steps and try to find what went wrong.
Whether someone helps you or not, eventually, your API will be running on your web page, and your email inputs will only provide real email addresses that you want!
