Read the channel attached to the allowance: the displayed first contacts are over SMS.
The product in view
senderZ displays Starter at a $39 monthly equivalent billed annually, or $468 per year. That plan uses a shared number and includes 250 first contacts monthly over SMS, with a ten-per-day allowance. It then describes unlimited iMessage once the recipient texts back. Growth displays $199 monthly on annual billing with one dedicated number and larger first-contact allowances.
Before you choose
Confirm the actual monthly-billing price and the transition from initial SMS to a replying conversation. Do not rewrite those terms as unrestricted outbound iMessage. The model can be relevant to teams with a defined contact list, but it needs a workload estimate based on newly reached people and the precise channel used.
