If I didn't get my registration email, what should I do?
We know this can be a bother, but being patient and checking the junk folder are our best practices!
Can I use my credits in order to verify in real-time with your API?
This may seem like a leading question, but YES! You can absolutely use our API for your website forms or other creative ways to filter your email lists from the source. You can find instructions on how to do this here to find more details about instructions.

File or API: Which should I use?
If you need real time validations -- for example, if you want to verify your users' email addresses during the sign up process and reject them if they are invalid -- the API is going to be the faster and easier choice. If you need to validate lists, either as a one off or once every few days/weeks, then it's easier to use the browser and upload all your emails at once.
