Buying or receiving in any way an email database is no longer legal now since GDPR. Any emails that aren't opt-in , meaning users that have deliberately given you permission to use their email addresses for campaign and newsletters, aren't accepted anymore.
The best way would be to build up your email database with users of your platform at registration and once you have it you will need to clean that email list before sending out any newsletters.
Without validating those emails you will surely encounter a high volume of bounces which will damage your sending reputation and get you blacklisted eventually.
But for your email validation needs I would recommend using Zerobounce ,
it’s the best email validator service with an accuracy rate of 98%+ and you can test the platform with the 100 free credits you receive once you register for an account.
They also have a reliable API, easy to implement and great to keeping an efficient and clean database.
