Compared at the same emails a day, each vendor at its own published emails per mailbox a day: a cheap mailbox that sends 5 a day costs more per email than one that sends 25. Mailboxes = emails a day ÷ emails per mailbox a day (Puzzle Inbox: 3, its cap for Outlook 365; Google is 12 a day at $3, a higher cost per email; Outreach2day: 25). A month is 22 sending days, so emails a month = emails a day × 22. Monthly list prices on monthly billing; the Instantly plan is the cheapest one that covers the volume. Puzzle Inbox does not publish a domain price, so its domains (100 mailboxes each) are left out of the total, marked "from"; Outreach2day .com domains at $13 a year, 5 mailboxes per domain. Domains spread over 12 months. Outreach2day mailboxes on comparison pages: $2.50 a mailbox up to 99, $1.50 from 100, $0.50 from 1,000; larger volumes on the Enterprise plan. A mailbox-only vendor cannot send campaigns on its own, so its total is the full sending setup: its mailboxes, domains and the sequencer plan that covers the volume. Instantly is the reference sequencer, on its published plans for the emails and new contacts a month (emails ÷ 3); Smartlead where Instantly publishes no plan; Mailforge with Salesforge, because its mailboxes cannot be warmed in Instantly. The mailbox line is listed on its own in every cell.
