Sign up goes well. But your email confirmation link seems to be broken or on a reject list: when I click the link, then it fails from domain "pstmrk.it" and doesn't seem to reach rownd.io. IMHO email confirmation links should go directly to the expected domain and company, not anywhere else.
Sorry it didn't work for you! Do you happen to be using a service like Pihole, etc to block specific domains on your network?
We currently use Postmark for sending transactional email and by default, they rewrite all links to use their tracking servers. We didn't intend to have that enabled, so apologies for the oversight. I've just disabled that option, so links should resolve to their intended destination now. Links that go through multiple tracking redirects are a personal pet-peeve of mine as well!
Don't beat yourself for this mistake. We had a similar problem with emails where the provider was adding tracking URL by default. We had no idea until a client complained that it was blocked by their firewall/network. We then had to turn that off option which is enabled by default. Sneaky.
Thanks for checking... I use Fastmail and Firefox with EFF Privacy Badger and uBlock Origin. If you want to send a new email, I can try it for you. Email is joel@joelparkerhenderson.com.
