> If you don’t have a problem with user quality then sure, avoid the verification step. But if you have a good reason for the verification step then don’t sweat the drop-off rates.

If you have any contact method for the user (email, SMS, phone) you should be doing some level of verification on it. Users are clumsy, some of them don't know or mistype their own email addresses, phone numbers, etc. Verification ensures you're talking to the person you expect to be talking to.
