SendCanyon rows come from our own product documentation. Competitor rows are compiled from each vendor’s public material and change often — read a plan page before you buy. Tell us about anything that looks wrong and we will correct it.
Three rows above change how the work feels day to day. These are the ones people mention back.
01
SendCanyon prices the mail you send. Adding a teammate changes who can log in, not what you pay.
From the table: Priced on sending volume rather than per seat
02
Pacing and rotation are enforced by the sender itself. When a mailbox falls out of its thresholds, SendCanyon takes it out of rotation that day instead of waiting for you to notice.
From the table: Sender pulled automatically the day it stops qualifying
03
Authentication, warmup history and mailbox health are checked at launch. Launching on a domain that is still warming needs an explicit acknowledgement first.
