Welcome to SendGrid’s Web API v3! This API is RESTful, fully featured, and easy to integrate with.
Easily check if a certain e-mail address is valid. Is it a valid domain? Is the e-mail a temporary/disposable e-mail? That's a common indicator of spamming/trolling, so now there's an API for you so you can easily block it!
Email Validation Service. Use ZeroBounce's email validation API to increase your email marketing ROI! Remove invalid email addresses from your list using our unique email verification scrubbing system to prevent email bounces.
Regulus Email Validator is a simple and powerful REST-based JSON API service, protected by 256-bit encryption. Its main purpose is to help to filter "real" customers from abusers, increase response and success rates of your email campaigns and avoid getting into spam filters. Our service allows you to instantly verify email address: perform a syntax check, verify the existence of the domain and mail server records. It also provides the following information about the email address: if it is free, disposable, role, etc.
Checks for fake DNS as well as uses regex functions to check the email for the right length and accepted characters. For example it will mark as valid an email like '[email protected]' but it will recognize as a fake '[email protected]' (because of the not existing domain)
Email validation made easy. Simple REST API for checking the email format and predict deliverability. Validation is done via format validation, general DNS check, MX records check, social signals and checks for various negative patterns (eg. [email protected]) . Also checks if the email is disposable or a "spam trap". "Deep" SMTP validation is coming soon.
Email is essential to pretty much every application. Consumers use their email addresses as login for applications and expect to receive notifications and messages. Use email validation APIs to block account creation with temporary or fake email addresses. Use email APIs to send transactional emails such as password resets or notifications and marketing emails such as newsletters.
