What are the services of email newsletters without recipient confirmation?

Question

Email

Hello.
I need an email service. The main requirement is that the recipient does not have confirmation of the mailing, as for example in Unisender.
That is, I compiled a database of subscribers, imported it, launched the mailing list. The recipient receives a letter.
No "confirmation" mailing.
