Update to review:

SalesBlink has come back online and seems to be functioning normally. This is one of the downfalls of using AppSumo. These applications are developmental and often under work. The biggest complaint that I would say is there was no notice of the outage sent to customers. This makes it seem like a rug pull occasionally. For the Founder: when you have outages that last more than 30 minutes, it should become standard practice to alert users. Given you have a place to promote features in the app, it would be very powerful to also update on outages here with estimated timelines to restore service.

I'm leaving this review to warn other potential buyers. The SalesBlink platform is currently non-functional due to several critical, unaddressed issues.
My experience has been:
Broken SMTP Integration: The main reason I purchased this was for email outreach, but the SMTP integration has been completely broken for going on 10 days. This makes the entire app pointless.
Non-Working List Verification: The feature to verify email lists does not work.
Lackluster Email Drafter: Even the more basic features, like the email drafter, are poorly implemented and unimpressive.
You are essentially paying for a nice-looking interface with no practical function behind it.
What's most concerning is the consistent JavaScript error showing that their logging service has "exceeded their quota." This gives the strong impression the company is having serious operational issues. I would advise against purchasing this until there is clear evidence the product is functional.
