Start with 500 free checks; paid credits never expire.

Email verification is crowded, so speed alone won't win. What's the advantage you expect developers to remember six months after integrating MailSift?
@aryan787544 you can discard fake users before they register on the site
It would be super useful if the API response could flag whether an email belongs to a free provider like Gmail or Yahoo separately from the risk score, since that distinction matters a lot for B2B vs B2C campaigns and currently requires a separate lookup.
@cervantesh93980 it does
Finally something that catches the typo emails I keep getting in my signups. The trust score idea is genuinely useful for deciding what to do with borderline addresses.
