12 Steps To Find The Perfect API To Verify Email Address

Sending emails to the correct clients is essential for any marketing strategy to improve conversion rates. However, for your campaign to be effective, you must guarantee that your database does not contain any false email addresses. This is when an effective email API comes in handy. An API to verify email address assures that your database only contains valid email addresses and client contact information. In addition, an email validator API examines email IDs’ validity to remove bogus ones from your database. As a result, you may effectively build your business by sending emails to the correct consumers and high-value connections.

Mailboxlayer is one of the best APIs to verify email addresses. Moreover, it provides a simple REST-based JSON API that allows you to examine and validate email addresses at entry thoroughly. Consequently, most people regard it as the most incredible email service API. This article will focus on 12 steps users should take to find the perfect email verifier API.

API to verify email address provide its customers with full verification

1. Does the Email API Have a Documentation?

API documentation is essential as it increases API adoption. Comprehensive documentation on every functionality, how to use and integrate it, and updates on the API lifetime improve the experience for those who use your APIs.

An email verifier API must be able to provide its customers with detailed documentation, and mailboxlayer offers just that. A customer can go through the documentation to understand every aspect of this fantastic API, ranging from access specifications to API validation tools. You’ll be able to check out the API’s features as you go through their documentation once you’ve joined up. Mailboxlayer provides excellent detailed documentation, errors, and code examples that a user can look through to better grasp the email verifier API. You can check out the official documentation and see it for yourself.

2. Can You Use HTTPS to Encrypt Your API Requests?

HTTPS helps prevent outsiders from interfering with communications between your websites and your users’ browsers. This is a fundamental feature that every email verifier API must have.

Using the industry-standard SSL, any Customer using mailboxlayer API can access all data given and available through the API. Simply add an s to the HTTP Protocol to establish a secure connection, making it https://. Thus, users can ensure secure and encrypted datastreams by connecting to the API via industry-standard HTTPS.

3. Do the API Users Have Access to Their Usage Statistics?

The mailboxlayer API allows you to track your API daily or monthly API consumption. In addition, it sends you automatic alerts when you’re running short. Furthermore, the mailboxlayer API limits the requests to the API based on your current subscription plan. The limit is based on the number of requests received every minute. So if you cross your rate limit, the API will return an error carrying the type rate_limit_reached. This probably makes mailboxlayer the perfect email verifier API.

Is the API to Verify Email Address Simple And Secure

4. Does the API Provide Syntax Check on API Requests?

Syntax checks can be beneficial and time-saving as they would require less debugging. When an email address is requested to be verified, the mailboxlayer API will first do a regular email syntax check, ensuring that it complies with regular expression criteria (for further details, visit the API’s documentation). The format_valid JSON object in the API response will return true or false depending on whether the email’s syntax is valid.

5. How Does the API Provide Typo Checks and Suggestions to The Users?

Along with the essential syntax checks, it is always a bonus that an email verifier API provides both typo checks and suggestions. This is precisely what is expected of the perfect API since it is the epitome of efficiency. 

Suppose the mailboxlayer API identifies a likely misspelling or error in the domain component of the requested email address. In that case, it will provide an alternate email suggestion in the did you mean object of the API return set. However, the critical point is that the email address in the did_you_mean object is merely a suggestion and has no influence on other API response objects.

6. Is Email Verification Done in Real-Time?

The mailboxlayer API checks email addresses by looking for MX-Records and utilizing SMTP, or Simple Mail Transfer Technology, which is the protocol that we all use to send and receive emails over the internet.

Our system starts the real-time email verification process by determining if the requested domain is set up to receive email. This is where the MX-Records check in the API comes in handy. The API’s mx _found response object will notify you if MX-Records for the provided domain is found.

For each email address, the mail server is contacted via SMTP. The SMTP dialogue that follows is the most crucial aspect in determining whether or not the email address provided is valid. The smtp_check JSON object in the API response will return true or false based on whether or not an SMTP check was successful.

7. Can You Role Check an Email Address with the API?

The technique of determining whether or not the requested email address is a role email address is another aspect of mailboxlayer email verification. A role email is an address that usually refers to a function (such as “support” or “postmaster”) rather than a specific person or name. It is an essential function that every email verifier API must have. Check out this article to learn why you shouldn’t ignore email checks.

Because open rates are often poor, this sort of email address is not desirable when delivering email marketing. Therefore, if the requested email is a role address, the role JSON object in the API response will return true or false.

8. Can You Check Which Email Provider an Email Corresponds to?

The mailboxlayer API connects to a regularly updated database of all accessible email providers, allowing it to detect free email services such as Gmail and Yahoo! The free JSON object in the API response will return true or false depending on whether the requested email address is discovered to be utilizing a free service.

9. Does the API Rate the Quality of Your Requested Email Address?

The perfect API rates how good or bad the user’s requested email is. Mailboxlayer does precisely that.

The mailboxlayer API will provide a numeric Quality Score ranging from 0 (Bad) to 1 (Good) to indicate the quality and deliverability of the given email address at the end of the mailboxlayer validation and verification procedure. Intelligent algorithms evaluate email addresses using three primary factors: appearance, deliverability, and background. Using these factors, the API provides a Quality Score for each email.

10. What Error Codes should You Expect When Your Query Fails, and What do They Mean?

As previously stated, error codes are incredibly useful. The most straightforward way for a developer to communicate failure to a user is via error codes in the API response stage.

If your query fails, the mailboxlayer API will respond with a 3-digit error code, an internal type error, and a plain text “info” object containing suggestions for the user. You can visit the mailbox’s official documentation to learn more about error codes and their meaning.

11. Does This API Provide Code Examples for Its Customers?

Code examples allow a user to understand better how to use the API in a specific programming language. Mailboxlayer has several intuitive and detailed code examples in PHP (cURL) and JavaScript (jQuery.ajax). So if you are just starting with mailboxlayer, these examples will prove useful in understanding how to write API queries and what kind of API responses to expect.

12. Does the Email API Have Any Unique Features?

The perfect email API would have everything other APIs have, but it would also have some unique and helpful features that set it apart from the rest. One such example is the catch-all detection feature of mailboxlayer.

The real-time verification procedure of the mailboxlayer API does not conclude with a single SMTP check. Instead, a catch-all detection mechanism catches all incoming mail traffic to servers. All of which is entirely independent of the local portion of the email address’s request.

Due to its significant impact on the API’s response time, it is disabled by default. However, by inserting the API’s catch_all parameter to the request URL and setting it to 1, you may enable catch-all detection.

Do You Now Know How to Find the Perfect API?

Now you know that after looking for basic features of an email API, such as documentation, you must find premium features that are like the “cherry on top” for you as a user. Mailboxlayer is one API that gives us a positive response to all the 12 steps defined. It has grown famous as a real-time API validation and verification solution.
