Everything is in one place: domain registration, DNS configuration (SPF, DKIM, DMARC), mailbox warming, and campaign sending. I didn't have to touch any DNS panel or configure a mail server. It was enough to provide the domain name, pay, and after a few minutes, the mailbox started warming up on its own. I particularly like the lead verification; the system checks each address with three methods before sending an email, which greatly helps in maintaining a good sender reputation. The interface is in Polish, which is rare for cold mailing tools as most competitors are English-language products without localization. For someone who wants to get into cold emailing without technical knowledge of SMTP or DNS, this is the fastest start I know.
