Email Sequence
If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.
Design and draft complete email sequences with full copy, timing, branching logic, and performance benchmarks for any lifecycle or campaign use case.
Trigger
User runs /email-sequence or asks to create, design, build, or draft an email sequence, drip campaign, nurture flow, or onboarding series.
Inputs
Gather the following from the user. If not provided, ask before proceeding:
Sequence type — one of:
Onboarding
Lead nurture
Re-engagement
Product launch
Event follow-up
Upgrade/upsell
Win-back
Educational drip
Goal — what the sequence should achieve (e.g., activate new users, convert leads to customers, reduce churn, drive event attendance, upsell to a higher tier)
Audience — who receives this sequence, what stage they are at, and any relevant segmentation details (role, industry, behavior triggers, lifecycle stage)
Number of emails (optional) — if not specified, recommend a count based on the sequence type using the templates in the Sequence Type Templates section below
Timing/cadence preferences (optional) — desired spacing between emails (e.g., "every 3 days", "weekly", "aggressive first week then taper off")
Brand voice — if configured in local settings, apply automatically and inform the user. If not configured, ask: "Do you have brand voice guidelines I should follow? If not, I'll use a clear, conversational professional tone."
Additional context (optional):
Specific offers, discounts, or incentives to include
CTAs or landing pages to link to
Content assets available (blog posts, case studies, videos, guides)
When the user wants to create or optimize an email sequence, drip campaign, automated email flow, or lifecycle email program. Also use when the user mentions "email sequence," "drip campaign," "nurture sequence," "onboarding emails," "welcome sequence," "re-engagement emails," "email automation," or "lifecycle emails." For in-app onboarding, see onboarding-cro.
