Abuses service providers, tries to make them look bad for protecting themselves
I would like to review Yosif Limited as someone who did business with them for 29 months (From May 2017 to October 2019). As a customer of mine (I'm an email service provider), on October 09 2019, Yosif Limited sent 1,481 emails within one hour to a large list of recipients, a great number of which were invalid email addresses. The subject of this email advertised a product that they were actively marketing on their company Facebook page, which indicated that this was intentional and not a compromised email account. That proves both intent and the lack of a valid opt-in procedure. It is then a confirmed fact that the customer sent bulk unsolicited marketing emails, as consent could not have been confirmed by the invalid recipients. We immediately sent them this email, for which their email provider offered the code "250 2.0.0 OK 1570616749 l67si679249ybf.326 - gsmtp" as proof of delivery:
"Your account has been terminated for actively and intentionally engaging in the sending of unsolicited marketing emails. This is not a mistake and the information has been verified fully, there will be no exceptions."
A short time later, Yosif Limited wrote a bad review about our company, referring to us as a "scam," in bad faith. You should know who you are doing business with, and I hope that this helps you to make the right decision.
