Stands out for: Your own mail server and IP, with unlimited free inboxes and developer API access on every plan.

Overview

Mailreef sells dedicated mail servers for cold email, with a dedicated IP, unlimited inboxes, and one-click domain and mailbox creation. Agency is $240 per month on a 12-month commitment, plus $0.001 per send. Agency Flex is $249 per month, cancel anytime, with the same send fee. Enterprise is custom. Every plan includes auto SPF, DKIM, and DMARC, live technical support, developer API access, server monitoring, and Smartlead and Instantly integrations. You can bring your own domain or buy in product.

High-volume senders pick Mailreef to own the server instead of renting shared SMTP. Unlimited inboxes sit on that server, so the bill is the server plus sends, not per mailbox. There is no published free trial. Buying starts with a demo. The $240 figure is the annual-commitment Agency rate, not the month-to-month price. Owned under Dabble Holdings per the site footer.
