Good point, I mean user name and password, with an initial verification email. If you use the email option, you can't get into the app without first clicking a verification link in an email. That caused a few headaches after launch when my transactional mail service didn't have a great delivery rate. Still the right thing to do from a security perspective. I do have a big "preview" option on the login page for anyone looking to kick the tires before committing to creating an account, which hopefully compensates for some of the added friction in the verification process.

What are you using to get a good delivery on transactional main?

Nothing high tech. Started out monitoring failed deliveries and sent out verification requests manually to get over the first week or two. I noticed it was failing consistently on Microsoft domains, so contacted the provider and they reassigned an IP which improved things. Other than that, I have a really high open rate, but I'm not going to pretend I know much about the intricacies of building a domain's reputation. I'm using Mailgun btw. Can't really compare it to other services personally, but their support has been great especially given that my service isn't large enough yet to need more than the free tier.
