Put Dana Whitfield at Harborview on my three-email first touch from the warmed inboxes on tryleaseline.app, and show me email 1 before it sends.

Responsibilities
- Builds each list from one ICP sentence, and keeps only people at companies that fit with quoted evidence.
- Checks every address before the first send, and stops a batch when bounces pass 2%.
- Sends cold first touches only from the 2 warmed inboxes on your second domain, 25 a day each after a 14-day ramp; warm intros and replies go from your own inbox.
- Reads every Suppression before each send, so an opt-out binds within the hour.
- Routes each reply within the hour: interested to a booked call, technical to the SE seat, stop to
Contact.suppress.

Approvals
You see the plan and its price before anything runs. Sends and posts go out within the limits you set; one approval rule on a class such as send makes every action in it wait for you, and going over a limit always asks.
| It asks you | When | Answered by |
|---|---|---|
| Enroll more people than the day allows | A batch would pass the daily pace you set for that Mailbox | You |
| Send from a new Mailbox | Before the first send from an address you have not authorized yet | You |
Each class and its default amount: the hub’s approvals page.
Works with
- Booked first calls (Service): Held first calls with buyers who fit, a budget owner confirmed on each, billed per held meeting against a monthly target you set.
- Build a verified list (Workflow): One sentence in, 100 checked work emails out, each at the right company, with the quote that shows the fit.
- Demand generation (Service): Your strategy’s Plays run for the month, billed per qualified lead, and every lead and dollar of revenue traced to the Play that sourced it.
- List refresh (Workflow): Every month, each row on your list re-read: who moved jobs, which companies changed, and which addresses bounced, as a new version of the list.
- Personal first touch (agent task): Your verified list in, a first email to each person whose opening line quotes their own company, then two follow-ups that each add something new.
- Pick who to sell to first (Workflow): Two to four customer sentences in, each scored on pain, deal size, reach, warm paths and proof, and five discovery calls set on the winner.
- Verified list with a bounce warranty (Service): A list of checked work emails at the right companies, billed per contact; every bounce over 2% at first send is credited and replaced.
It trades hand-offs with AE, SE and Marketing lead.
Example
On Monday the agent enrolls the 50 verified heads of operations and sends email 1 from dana@tryleaseline.app and dana.okafor@tryleaseline.app, 25 from each. Dana Whitfield at Harborview Property Management replies on day 3 about rent ledgers, so her sequence stops, the answer goes from dana@leaseline.app, and a call lands on the founder’s calendar that afternoon.
