Is there any API that developers could use?
An API is the program interface, which is specifically designed to connect with the ‘processing core’ of some email verifying software (in so-called thin or thick clients). Typically, an API for an email address checker is made of several strings of code, which make it possible to connect to an email checker and make bulk queries for the check. The API can be realized as a separate installable program – usually, an app for a PC or mobile/tablet – in case if the company’s programmer will not work out the technical integration of the company’s programs using the given open code.
API is mainly needed to process batch checks in order to check if the email is real – up to millions of strings of data during one request.
Frequently asked questions
What are the limits of free lookups?
Usually, not more than several of them per 1 day or month. The checks are, as a rule, connected with 1 IP. By switching the IP, it is possible to run more checks. But don’t think that you will be able to run thousands of checks in this way – still, it takes significant time and, eventually, that much data requires a subscription in order not to waste your efforts.
Is any data stored about the checked e-mails by the Gmail checker?
No. At least, not for long – it is erased at once as the check email is over and the results are delivered to users. During a single-address check, this can take seconds. During a bulk check, the temporary storage can take minutes or hours.
Do the checked email address owners get informed about the email validation?
No.
