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.
This is an easy way to check if a email address is acceptable so you can avoid fake/invalid users on your database.
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@example.com' but it will recognize as a fake 'firstname.lastname@example.org' (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@example.com) . Also checks if the email is disposable or a "spam trap". "Deep" SMTP validation is coming soon.
Valid email addresses are essential for marketing campaigns in creating traffic, enhancing engagement, and increasing leads. However, typos, honest or intentional mistakes during signup for email subscription may result in a high bounce rate causing email ISP to flag your domain or IP address as duplicitous. Using email API to check if the email is valid is essential.
Email application programming interface is a preprogrammed application to check if the email addresses are transferable and valid by removing fake, misspelled, or dark mails. The email application programming interfaces help to ensure that emails are delivered.
Email address Validation API is integrated into your website or application to examine syntax and domains’ correctness. The Email APIs verify the emails using a set of stages. These include a syntax check to check for the email prefix and the domain followed by an address name detection to flag any suspicious email names.
The API then conducts a disposable email address (DEA) detection to identify and remove spam emails. The email application programming interface then removes spam traps from the email lists before running the mails through a uniform resource identifier and a DNS-based blackhole list. The mails then pass through MX record lookup to identify any invalid domains before sending the API sends a ping request to the email address server for authentication.
If you are tired of hard bounces, complaints about spam, or getting blacklisted by the server, email address verification API is the lifesaver that your business requires. An email verification API is suitable for a first-time user. A new user using emails to reach out to the client can easily misspell or have included the wrong domain.
Email verification API has simple and easy to follow codes that are of use to a developer. This way, the developer does not have to start from scratch while creating a verification form for emails.
An email address validation API improves your deliverability to nearly 98%, thereby maintaining a high Sender Score and mailbox provider trust. The API’s ability to check if the email is valid will increase conversion rate and ROI as emails get to the intended persons.
By using Email application programming interface, you should expect an improved customer experience, reduced marketing expenses, enhanced sales efficiency, and excellent sender reputation. One can also use the API to check if the email is valid, suspicious, or spam.
