Can anyone recommend any reliable email verification APIs?
I have a SaaS business, and I want to avoid users who try to abuse my freemium service. Please recommend some APIs that you had a good experience with.

Hi All,
I know this is an old post, but I am writing here for someone who is looking for a reliable API.
We have built this real-time email verification API service published on RapidAPI:
https://rapidapi.com/nitinksaas/api/real-time-email-verification-api1
This API is the one and only reliable solution to verify that the email address is valid and reachable. We achieve this functionality by validating with regex, validating the DNS for MX records, and then connecting the recipient’s SMTP server for verification.
We have maintained our database with a popular disposable email service provider. Currently, we have more than 170K domains, and we daily update our database with new disposable email domains as they are created every day. Also, we use reputed IP addresses to give you the best verification results.
Yes! This email verification API actually connects to the mail server and checks in real-time if the email exists.
Do check this API service out! Let me know if you are just starting out, I am happy to help with our custom plans.
I also have a SaaS company and have tried different email validation tools to prevent users from abusing my freemium offers. I’m currently using this email verification API https://emailverification.whoisxmlapi.com/api, and so far, so good. It detects disposable email addresses, which freemium abusers sometimes use to sign up.
This email verification API also performs email-sending emulation through Simple Mail Transfer Protocol (SMTP) checks. This means that it can check if the email address used upon signup can still receive emails. If not, its “user” would be detected and not allowed to sign up.
The reason why I thought this is important to mention is because not all abusers employ disposable email addresses. Some may use the usual email providers like Gmail and Yahoo. They designate one email to receive newsletters and marketing messages so they may never open these. These email addresses can be dubbed “temporary” and can quickly reach their limits because of the massive amount of marketing emails they get. And they are detrimental to SaaS companies like ours.
