Persona Stacks
4 outbound stacks mapped by persona
Defining constraints, core tools, and dedicated guides for each profile.
Founder-Led Outbound
Constrained by time, not budget. Must run in 2-4 hours/week without dedicated ops. Instantly or Smartlead covers sending and warmup. Apollo free tier covers prospecting. A single Zapier workflow pushes replies to Slack or a lightweight CRM like Breakcold or Close.
Instantly or Smartlead
Apollo free or basic
Breakcold or Close (CRM)
SDR Team
Constrained by coordination and visibility. Manager needs per-rep reporting, shared sequences, and meeting attribution. Smartlead or Apollo handles sequencing. Clay or TexAu handles enrichment. HubSpot or Salesforce manages pipeline. Lavender coaches email quality per rep.

Outbound Agency
Constrained by client isolation: one client's spam issue cannot affect another's reputation. Smartlead sub-accounts or Instantly agency plan handle multi-client inboxes. Woodpecker's slot-based billing scales economically above 10 clients. White-label reporting is required, not optional.

GlockApps or Folderly (per-client)
Recruiter Outreach
Constrained by GDPR compliance and a candidate-first workflow. LinkedIn is the primary channel: Heyreach or Waalaxy runs sequences. Kaspr or Lusha provides direct numbers and work emails. The funnel ends at a screening call, not a sales discovery call.

Persona Comparison
4 personas: how stack priorities differ at a glance
| Persona | Ops time/week | Primary channel | CRM from day one | Most critical feature | Stack guide |
|---|---|---|---|---|---|
| Founder | 2 to 4 hours | Cold email | Optional | Autopilot warmup + simple setup | Founder stack → |
| SDR Team | Dedicated ops function | Email + LinkedIn | Required | Per-rep reporting + attribution | SDR team stack → |
| Agency | Per-client management | Cold email (multi-client) | Per client (optional) | Client isolation + white-label reporting | Agency stack → |
| Recruiter | 4 to 8 hours | LinkedIn + email | Recommended | Phone data + GDPR compliance | Recruiter stack → |
Persona Selection
Solo operator, SDR team, agency, or recruiter: pick your stack
Your Profile
You are the only person doing outreach at your company
The founder stack applies regardless of title. The defining constraint is solo operation in a few hours per week without a dedicated ops resource.
Founder-Led Outbound Playbook →Your Profile
You manage a team of two or more SDRs or BDRs
The SDR team stack applies once multiple reps need shared tracking and attribution. The critical decision: CRM and sales engagement platform must align from day one.
SDR Team Playbook →Your Profile
You run outbound campaigns on behalf of multiple clients
Client isolation is a hard requirement. Tools not designed for multi-client management create compounding deliverability and reporting problems above 3-4 clients.
Agency Playbook →Your Profile
You source candidates rather than sell products or services
LinkedIn is the primary data source and channel simultaneously. GDPR applies more strictly to personal data, and the funnel ends at a screening call, not a sales discovery call.
Recruiter Playbook →
Anchor on today's constraints, not future plans
A solo co-founder doing outreach is a founder stack, not an SDR team stack, even if SDR hires are planned. Right-size now and migrate when the team actually grows into a new profile.
