Best-in-Class SMTP Provider with Strong Deliverability

I have been using it for a year already. Out of all SMTP providers, this one is the best. First of all, I want to say – SMTP often shows higher results than GW or MS 365. The claim that SMTP allegedly works worse is tales told by sequencers, as it is important for them to attract clients with GW/MS mailboxes. In reality, spam filters do not care about SMTP – millions of emails (service, transactional, opt-in) are sent from SMTP, and nothing lands in spam.
