Mixmax platform help — sequences, email tracking, one-click meetings, rules engine, dialer, AI Compose, Salesforce/HubSpot integration, polls, reporting. Use when Mixmax sequences aren't sending, rules or automations aren't firing, Salesforce or HubSpot sync is broken, scheduling links aren't working, open/click tracking seems inaccurate, or Mixmax emails are landing in spam. Do NOT use for general outbound cadence strategy (use /sales-cadence), cross-platform email deliverability (use /sales-deliverability), meeting scheduling strategy (use /sales-meeting-scheduler), email tracking strategy (use /sales-email-tracking), or connecting Mixmax to other tools via Zapier (use /sales-integration).

Help the user with Mixmax platform questions — from sequences and email tracking through one-click meetings, rules engine, dialer, AI Compose, Salesforce/HubSpot integration, polls, and reporting.
If references/learnings.md exists, read it first for accumulated knowledge.
Ask the user:
What area of Mixmax do you need help with?
What's your role?
What are you trying to accomplish? (describe your specific goal or question)
If the user's request already provides most of this context, skip directly to the relevant step. Lead with your best-effort answer using reasonable assumptions (stated explicitly), then ask only the most critical 1-2 clarifying questions at the end — don't gate your response behind gathering complete context.
Note: If the user needs a specialized skill, route them there with a brief explanation of why that skill is a better fit.
If the request maps to a specialized skill, route:
/sales-cadence/sales-deliverability/sales-meeting-scheduler/sales-email-tracking/sales-integrationOtherwise, answer directly from platform knowledge using the reference below.
Read references/platform-guide.md for detailed module documentation, pricing, integrations, and data model.
You no longer need the platform guide details — focus on the user's specific situation.
Based on the user's specific question:
Best-effort from research — review these, especially items about plan-gated features and integration gotchas that may be outdated.
Mixmax is Gmail-only — there is no Outlook support. Mixmax works exclusively as a Gmail/Google Workspace extension. Don't recommend Mixmax to users on Outlook or Microsoft 365. If they need Outlook support, suggest alternatives like Salesloft, Yesware, or Mailshake.
Salesforce advanced rules require Growth+CRM plan (~$89/user/mo). Basic Salesforce sidebar and activity logging are on the Growth plan, but rules triggered by Salesforce objects (opportunities, accounts, custom objects) require Growth+CRM. Always ask about the user's plan before suggesting SF-triggered automations.
The Contacts API is deprecated. Don't recommend building integrations against the /contacts endpoints. Use Salesforce or HubSpot as the contact source of truth instead. The contacts endpoints may be removed in a future API version.
API rate limits are undocumented. Mixmax does not publish official rate limits. The API is described as "optimized for lightweight, real-time interactions" — it is NOT suitable for bulk exports or high-volume sync. Recommend building with conservative backoff and small batch sizes.
One-click meetings require the recipient's email client to render rich HTML. If the recipient uses a plain-text email client or has images disabled, one-click meeting proposals won't render correctly. They'll fall back to a scheduling link, but the one-click experience is lost.
Self-improving: If you discover something not covered here, append it to references/learnings.md with today's date.

references/mixmax-api-reference.md for full API documentationX-API-Token headerSymptom: Emails show as sent but no open notifications appear
Cause: Recipient's email client blocks tracking pixels (Apple Mail Privacy Protection, corporate proxies), or tracking is not enabled for the message
Solution: Verify tracking is enabled in the Mixmax compose window before sending (tracking toggle should be on). Note that Apple Mail (iOS 15+) pre-loads images, which may inflate or block accurate tracking. For critical prospects, rely on click tracking (include a link) and reply tracking instead of open tracking. See /sales-email-tracking for a full tracking strategy.
Symptom: Advanced rules configured to trigger on Salesforce object changes are not firing Cause: Not on Growth+CRM plan, Salesforce connection expired or disconnected, rule conditions too narrow, or Salesforce sync delay Solution: Confirm you are on the Growth+CRM plan (~$89/user/mo) — advanced Salesforce rules are not available on lower plans. Re-authorize the Salesforce connection in Mixmax settings. Check the rule conditions — test with a broad condition first, then narrow down. Allow up to a few minutes for Salesforce sync delays.
Symptom: Recipients report sequence emails going to spam or not arriving
Cause: Domain not authenticated, sending too many emails too fast, or email content triggering spam filters
Solution: Verify custom sending domain with SPF/DKIM/DMARC authentication. Start with low volume and ramp up gradually. Avoid spam trigger words in subject lines and body. Use Smart Send to optimize send times. Check sender reputation at mail-tester.com. See /sales-deliverability for a comprehensive deliverability strategy.
