Step 1 — Gather context
If references/learnings.md exists, read it first for accumulated platform knowledge.
-
What are you trying to do?
- A) Build a MailingBoss API integration — sync contacts/tags into a CRM or warehouse
- B) Set up an inbound webhook — push leads from a form/app into a MailingBoss list
- C) Configure a module inside Builderall — funnels/pages, MailingBoss email, SuperCheckout, courses/membership, webinars
- D) Pick a plan — Free vs entry vs funnel/marketer tier
- E) Fix a problem — deliverability, outage, missing integration, overwhelm, migration
- F) Something else — describe it
-
Where does data need to flow? Stay inside Builderall / sync to a CRM or warehouse / drive an external app — this decides API vs webhook vs iPaaS.
Skip-ahead rule: if the user's prompt already provides enough context, skip to Step 2.
Step 2 — Route or answer directly
| If the question is about... | Route to... |
|---|---|
| Multi-step funnel strategy/structure across tools, or Builderall vs alternatives | /sales-funnel {question} |
| Email-marketing strategy and sequences | /sales-email-marketing {question} |
| Email deliverability / inbox placement | /sales-deliverability {question} |
| Course / membership / community structure and retention | /sales-membership {question} |
| Checkout / order-bump / upsell optimization across tools | /sales-checkout {question} |
| Webinar funnel strategy | /sales-webinar {question} |
When routing, give the exact command, e.g. "This is a deliverability question — run: /sales-deliverability {your question}".
Step 3 — Builderall platform reference
Read references/platform-guide.md for the full reference — the module map (what's API-accessible vs UI-only), the plan gates (the funnel builder usually sits on a higher tier), the MailingBoss list/subscriber data model with JSON shapes, and quick-start recipes (upsert a contact by email + tag it; push a lead from a form/app; tag-on-purchase follow-up).
Read references/builderall-api-reference.md for the MailingBoss API — base https://member.mailingboss.com/integration/index.php/, token-in-URL auth, the verified subscriber endpoints (create / search-by-email / update / unsubscribe), the documented-but-confirm list/campaign routes, and the inbound webhook pattern.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
Focus on the user's specific situation:
- MailingBoss is the only programmatic surface. Funnels, SuperCheckout, courses, CRM, webinars are UI-built. To move data in/out, use the MailingBoss subscriber API, the per-list inbound webhook, or Zapier/Make/Pabbly/Integrately — there is no broad REST API and no MCP server.
- Auth is a token in the URL path. The token is the last path segment; all other params go in the body. Treat the URL as a secret and rotate the token if it leaks.
- Dedupe on email, not
subscriber_uid. Subscribers are scoped per-list, so search-by-email first, then create-or-update (Recipe 1). - Tags do the work.
taginternalsdrives MailingBoss automations and segmentation — tag on opt-in/purchase, then trigger sequences off the tag. - Set the price expectation honestly. It's cheap at the entry tier, but the funnel builder and marquee features are usually gated to a higher (~$79.90/mo) plan — confirm the plan covers what the user needs.
- Deliverability and uptime are real risks. MailingBoss is weaker than specialist ESPs and reviews report periodic outages + slow support. For a launch, build/test ahead and keep a fallback; for inbox placement, route to
/sales-deliverability.
If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.
Gotchas
Best-effort from research (2026-06) — review these, especially plan-gated features and pricing, which change frequently.
- The funnel builder is often NOT on the cheapest plan. "Builderall is cheap" is true for the entry tier, but funnel building and heavier features have historically required a higher (~$79.90/mo) tier. Confirm the plan before promising funnels on the budget plan.
- Only MailingBoss has an API. Don't promise API access to funnels/checkout/courses — there isn't any. Plan integrations around MailingBoss subscribers + webhooks + iPaaS.
- The token lives in the URL. Anyone with the endpoint URL can write to your lists. Keep it out of client-side code and logs; rotate on leak.
- Periodic outages. Reviews report site, SuperCheckout, and email-send outages. Don't cut over mid-launch; keep a checkout/email fallback for time-sensitive events.
- Support is slow and has no phone line. Expect multi-day email/ticket turnaround — don't depend on support to unblock a launch.
- Deliverability is inconsistent. MailingBoss is frequently rated below dedicated ESPs. Authenticate your domain (SPF/DKIM/DMARC), warm up, and keep lists clean — or send through a specialist ESP and use Builderall for pages.
- Steep learning curve. Most users report 1–2 weeks to get comfortable; the breadth (50+ tools) overwhelms beginners. Start with one funnel + one list, not the whole suite.
- Subscribers are per-list. The same person on two lists has two
subscriber_uids — dedupe on email or you'll double-count.

Examples
Example 1: Sync app signups into MailingBoss and tag them (developer/automation)
User says: "When someone signs up in my app I want to add them to a MailingBoss list and tag them 'app-trial'. What calls?"
Skill does: Shows the upsert-by-email pattern (Recipe 1 in references/platform-guide.md): POST .../lists/subscribers/search-by-email/<TOKEN> to find an existing subscriber_uid, then create or update with email, list_uid, and taginternals=app-trial. Notes the token sits in the URL path, params go in the body, and to dedupe on email since subscribers are per-list.
Result: User has a create-or-tag flow and understands token-in-URL auth + per-list dedupe.
Example 2: A native integration I need doesn't exist
User says: "Builderall doesn't have a connector for my tool. How do I get leads into MailingBoss?" Skill does: Explains MailingBoss is the integration surface and gives two no-/low-code paths — the per-list inbound webhook URL (point your form/app webhook at it) or an iPaaS "Create MailingBoss contact" action (Zapier/Make/Pabbly/Integrately), plus the direct create endpoint for code (Recipe 2/3). Sets expectation that funnels/checkout themselves have no API. Result: User wires the missing integration via webhook or iPaaS.
Example 3: My Builderall emails go to spam
User says: "Half my MailingBoss broadcasts land in spam or promotions. Fix?"
Skill does: Explains MailingBoss inbox placement depends on the user's domain authentication and list hygiene, gives Builderall-specific first steps (authenticate the sending domain, warm up, suppress unengaged contacts, consider a specialist ESP for critical sends), then routes: "This is a deliverability problem — run: /sales-deliverability my Builderall emails are going to spam."
Result: User gets platform context plus the right strategy skill.
Troubleshooting
API write returns an error or the subscriber isn't created
Symptom: A create/update call fails or silently doesn't add the contact.
Cause: The token isn't the last URL path segment, params were put in the URL instead of the body, list_uid is wrong/missing, or a custom field tag (FNAME, etc.) doesn't exist on the list yet.
Solution: Put the token as the final path segment and send email + list_uid (+ field tags) in the request body. Create custom fields in the list settings before passing them. Log the raw response once to confirm the envelope, then map subscriber_uid from it.
Duplicate contacts piling up
Symptom: The same person appears multiple times.
Cause: Subscribers are scoped per-list, so blind create calls (or pushing the same lead to several lists) create separate records.
Solution: Search-by-email first and update if found (Recipe 1). Dedupe on email across lists in your own system; don't rely on subscriber_uid as a global id.
Funnel features aren't available on my plan
Symptom: The funnel builder or a marquee tool is locked. Cause: That feature is gated to a higher tier (the funnel builder has historically required ~$79.90/mo, not the entry/free plan). Solution: Check builderall.com/pricing for the current tier that includes the funnel builder and the specific tools you need before committing — the entry price doesn't include everything.
A send or the checkout suddenly stopped working
Symptom: Emails not going out, or SuperCheckout/page won't load. Cause: Reviews report periodic platform outages. Solution: Check Builderall status/community, retry, and open a ticket (expect multi-day turnaround). For launches, build/test ahead and keep an email/checkout fallback so an outage doesn't sink a time-sensitive event.
