How CallSine pricing works

Pricing model

Two tiers metered on campaign agents, connected mailboxes and daily new contact volume, with no seat concept.

The entry tier costs $349 a month for 1 campaign agent, 1 connected email inbox, up to 20 net new contacts a day, 14 days of analytics history and core content strategies.

The upper tier costs $999 a month for 2 campaign agents described as expandable, up to 10 connected inboxes, and up to 200 net new contacts a day with no total cap. An unlimited net new contacts entitlement appears above that.

The daily contact figure is a rate limit rather than a monthly quota, so capacity is bounded per day and does not accumulate across a month.

CallSine offers no annual billing option or discount, no trial and no free tier. It lists no rate for campaign agents beyond a tier's included count, although the upper tier is described as expandable, and no rate for mailboxes beyond a tier's allowance.

Setup and implementation

CallSine lists no setup fee, onboarding charge, migration rate, professional services rate, seat minimum or contract length, and offers no trial or free tier. A first agent can be launched and outreach started within minutes.

The expansion path cannot be modeled. The upper tier's two campaign agents are described as expandable without a rate for additional agents. CallSine does not say whether mailboxes beyond a tier's allowance can be added or at what cost, and with no annual option the monthly figures are the only rates.

The upper tier supports up to ten connected mailboxes, and a team using that capacity must procure, authenticate and warm ten domains and mailboxes itself. Mailbox providers typically charge roughly $4 to $12 per mailbox a month, and CallSine includes none of it, which is a meaningful line beneath a $999 subscription.

Analytics retention is fourteen days on the entry tier, a functional limit for any team measuring campaign performance over a quarter.

The daily contact allowance bounds what the product can do. At 20 a day, the entry tier reaches roughly 400 new contacts a month on working days. At full utilization that works out near $0.87 per new contact on the entry tier and near $0.25 on the tier above.

No total cap on the upper tier means the daily limit is a rate limit rather than a monthly quota. Unused daily capacity does not accumulate and cannot be spent in a burst, which matters for a team running campaigns in waves.

Mailbox counts are tier entitlements rather than add ons, so a team running several mailboxes knows which tier it needs. CallSine offers no annual option, no seat concept, no contract length and no trial, and lists no rate for campaign agents beyond the included two.
