Sending emails to the right customers is an essential part of improving a marketing campaign’s conversion rates. To make your campaign effective, however, you must ensure your database doesn’t contain fake email IDs. That is why you need an efficient Email API. An email address API ensures your database contains only authentic email addresses and customer contact information. An email validator API essentially checks the legitimacy, validity, and existence of email IDs to eliminate the fake ones from your database. That way you can grow your business by sending emails to the right customers and high-value contacts.
If you’re looking for the best email API, mailboxlayer is definitely the right choice. This article will show you 10 things about mailboxlayer that make it the best email API.

When you verify an email address using mailboxlayer, the API starts the process by performing an email syntax check. The API checks the email ID against regular expression rules like the email address format. For example, the format of an email address is ‘local-part@domain’. The local-part can have a maximum of 64 characters, while the domain can have up to 253 characters. In addition, the local-part can have uppercase and lowercase letters, digits from 0 to 9, and special characters. The domain part must match the requirements for a hostname, which consists of digits, letters, dots, and hyphens.
2. Does the mailboxlayer API Check an Email Address for Typos or Misspellings?
The mailboxlayer email API is capable of checking email addresses for typos and misspellings. It checks to see if there is a spelling mistake in the domain part of the email address and also suggests an alternative email address.
3. How does mailboxlayer Verify Email Addresses in Real-Time?
With the mailboxlayer email API, you can accurately verify email addresses in real-time. When the API checks an email address for syntax and typos, it uses MX-Records and SMTP (Simple Mail Transfer Protocol) lookups to verify them.
The real-time email verification process of the mailboxlayer email API is as follows:
1) Firstly, using MX-Records, the API detects if the requested domain is configured to receive emails. When it finds the MX-Records of a particular domain, the API returns a ‘true’ response through its mx_found response object.
2) Next, using SMTP, the API checks if the given email address actually exists.

4. Can You Verify Bulk Emails with the mailboxlayer Email API?
Businesses have email data for many customers and clients. However, verifying each email ID individually is very time-consuming. This is where you can use the bulk email verification of the mailboxlayer API. With this feature, you can request email verification for as many as 100 emails simultaneously, provided you’re using the Enterprise Plus plan. To verify multiple emails at a time with mailboxlayer, you simply need to append multiple email addresses, separated by a comma, to the base URL of the API.
5. What is the Catch-All Detection Feature of the mailboxlayer Email API?
Catch-all detection is a useful feature that lets you identify a catch-all mailbox. A catch-all mailbox is the one that is configured to catch any incoming emails sent to invalid email addresses on the domain. It’s crucial for businesses to detect such email IDs because they can result in high bounce rates. With the mailboxlayer API catch-all detection feature, you can effectively identify if an email address is catch-all and remove it from your database. This is one of those super-useful features that make mailboxlayer the best email API.
6. Can mailboxlayer Email API Separate Free Email Addresses From Individual Domains?
For most marketing campaigns, it’s essential to include free email addresses, such as Yahoo and Gmail, in your email list. But sometimes, for specific campaigns, you need to send emails only to IDs using private domains. This is where mailboxlayer can help you. The mailboxlayer email API is linked with a database (updated daily) that includes all available email providers. This allows the API to separate free email addresses from individual domains effectively.
7. Is the mailboxlayer Email API Capable of Checking a Role Email Address?
A role email address is one that usually points to a function like “postmaster” or “support” rather than a name. Sending emails to role addresses as a part of your marketing campaign can result in low open rates. In short, it’s better to exclude role email addresses from your list. That’s why mailboxlayer comes with the role check feature.
8. Does mailboxlayer Let You Check if an Email Address is Using a Disposable Email Provider?
A disposable email ID is created anonymously by a user, and it expires after use. These email addresses typically don’t require signup. As a result, anyone can view their inboxes. Sending emails to disposable addresses can negatively affect your marketing campaign. Instead, you can use the mailboxlayer email API to check if an email address is using a disposable email provider.
9. Does the mailboxlayer Email API Check the Quality of Email Addresses?
When you verify an email address, the mailboxlayer API provides a quality score that reflects its deliverability. The score ranges between 0 and 1, with 0 representing a bad score and 1 representing a good score. The API calculates the quality score based on appearance, deliverability, and background. Appearance compares the local and domain part of an email address to that of high-quality email addresses. Deliverability means checking if the email syntax is valid, while background means checking if the email address is free, disposable, or role.
10. Is the mailboxlayer Email API Easy to Use?
The mailboxlayer API is straightforward to use. You can quickly verify an email address with mailboxlayer by simply passing the email ID into the request URL. The API also provides results in the easy-to-understand JSON format. Mailboxlayer also comes with extensive documentation consisting of all the details about the API events and methods to make things even easier for you.
