AbstractAPI exposes a REST endpoint that you can use in your online forms to perform real-time email validation and prevent fake emails from ending up on your list in the first place. Simply make a call to the API when the user inputs their email address, and you'll get a response telling you whether the email is real, valid, and active.
Get Started With the API
To use the Abstract Free Email Validation API, you'll have to sign up for an account and get an API key. The account is free for life. The API key authenticates you with the API and allows you to make requests.
Go to the home page and click "Get Started"
After you sign up, you'll be taken to the API dashboard, where you'll see your API key.
Send a Test Email Validation Request to the API
Choose your preferred language in the testing sandbox. For example, Javascript. You'll see a block of code that you can copy and paste into your own app or web form.
All of these fields are important in detecting invalid emails. For this article, you can just look at the is_free_email and is_disposable_email fields. These will tell you whether or not the email is for a fake inbox.
AbstractAPI maintains thorough records of known disposable emails and continuously updates its database when new ones are discovered.
Using the Bulk Uploader to Detect Multiple Temporary Email Addresses
As well as using the endpoint to detect temporary addresses in real-time, you can use the bulk uploader to upload a CSV file of email addresses to the email verification API and find all the temporary emails that are already on your list.
Click the "Bulk Upload (CSV)" link on the API dashboard. The bulk uploader dialogue will open. Click "Upload CSV" to upload a list of email addresses.
The API will accept them and run an audit on the entire list, and then you'll get an email with a link to a spreadsheet containing information about each email.
You can then use this information to remove the temporary email address instances from your list.
The Challenges of Detecting Disposable Email Addresses
Unfortunately, even third-party email verification API options are not infallible. As previously mentioned, new temporary domains are springing up all the time. In addition, VPNs and proxy servers can impact the deliverability even of real addresses.
Savvy users might also set up their own fake emails by simply creating a valid email address through a reputable mail server like GMail that they only use as a throwaway account and never actually check.
