• Start with the simplest solution before suggesting complex workflows
• Reference specific Sendr UI paths or API endpoints
• If a feature is plan-gated (e.g., API access requires Pro), mention which plan
• If you discover a gotcha or workaround not in

Best-effort from research — review these, especially items about plan-gated features and integration gotchas that may be outdated.

• Credits don't roll over — unused monthly credits expire at reset. Plan usage carefully
• Each contact costs ~3 credits — dynamic audio + website background + landing page each consume a credit. At Growth plan (2,500 credits), that's ~833 personalized contacts/month
• Lipsync video is not true lip-sync — the video zooms into a circular bubble over the prospect's website background during personalized audio. This masks the lack of mouth animation. Don't promise full deepfake-style lip-sync to prospects
• No built-in email warmup — Sendr relies on external sending tools (Apollo, Instantly, Smartlead) for actual email delivery and warmup. Sendr creates the personalized content; you send it through your existing stack
• API requires Pro plan ($249/mo) — Growth plan users can't access API or webhooks. The automation builder is also Pro-only
• Lead Finder data is 479M+ contacts, refreshed monthly — accuracy varies by region (US data stronger than international)
• Support is chatbot-first — human support may be slow for pre-seed startup (1-10 employees). Community at community.sendr.io exists but is small
• AppSumo lifetime deal sold out Jan 2026 — new users are on monthly plans only ($97-$249/mo)

• Sendr uses a zoom-out-to-bubble technique, not true lip animation — slight timing offsets are expected
• Try re-recording the base video with a clear pause where the personalized name will be inserted
• Use the dynamic audio endpoint to preview audio before generating video
• If using ElevenLabs voice ID, check that language code matches the audio content

• Verify your plan has remaining credits (check Settings → Usage)
• Some operations require specific credit types — lead search vs enrichment vs verification
• Clear browser cache and try again — Chrome extension state can get stale
• Contact support at hello@sendr.io if the issue persists after credit top-up

• Each personalized contact consumes ~3 credits (dynamic audio + background + page)
• Batch-generate pages via API instead of one-by-one in the UI — API calls are more efficient
• Skip dynamic audio for lower-priority prospects — text-only pages cost fewer credits
• Monitor consumption in your dashboard — credits don't roll over at month end
