size_sending_capacity

Size the sending capacity

Act · mcp:actIdempotent

Computes and saves the sending fleet the campaign needs — mailboxes, domains, reserve — from the peak emails per day that estimate_campaign_plan returned, with the same contacts, horizon and calendar.

Description the model readsSent as is in tools/list.

Compute and save the sending fleet a campaign needs — mailboxes, domains, reserve — from the peak emails per day estimate_campaign_plan returned, passing the same contacts, horizon and calendar. Needs a confirmed target. Never derive the volume from a meetings target with a guessed reply rate. Resizing cancels a previous yes to the sizing.

Example

The user says

OK, size the sending for that.

Arguments

campaignobjectoptional

Pass the exact contacts/horizon/calendar from estimate_campaign_plan to preserve quota and pricing assumptions. targetEmailsPerDay must match its peak.

• contacts integerrequired1–1000000
• horizonDays integerrequired8–366
• calendar "every_day" | "weekdays"required

targetEmailsPerDayintegerrequired1–100000

The daily sending volume supplied by the founder or the peak returned by estimate_campaign_plan. Never derive it from a meetings target using an assumed conversion, reply, open or booking rate.

Good to know

• Needs a confirmed target.
• targetEmailsPerDay is the peak estimate_campaign_plan returned (or a daily volume the user gave).
• Resizing cancels an earlier yes to the sizing.
