Smartlead + Close integration

Smartlead finds the conversations and Close is where reps close them. OutboundSync puts every Smartlead send, reply, and category change on the Close Lead in between.

Smartlead + Close at a glance

Smartlead works with Close through OutboundSync. Smartlead sends, opens, link clicks, replies, bounces, unsubscribes, and lead category updates are logged as activity on the matching Close Lead. The sync runs one way, Smartlead into Close, and the OutboundSync team sets up the source and first test sync with you.

SetupGuided: the OutboundSync team runs onboarding

Teams pair Smartlead's inbox rotation with Close's calling and email workflow because each is strong at its half of the job. The weak point is the handoff: a positive reply sits in Smartlead while the rep who should call is in Close. OutboundSync moves that reply, and the whole sequence before it, onto the Close Lead.

Smartlead lead categories come across too, so the call list can be driven by what the prospect actually said. A Smart View filtered to recent interested replies becomes the rep's morning queue, and nobody has to check a second tool to find it.

Smartlead + Close FAQ

  • What Smartlead activity does OutboundSync sync to Close?
    Email sent, email opened, link clicked, reply received, email bounced, lead unsubscribed, and lead category updated.
  • Which Close records does it write to?
    OutboundSync matches or creates Close Leads. Smartlead events land as activity on the Close Lead. See the Close beta guide for details.
  • Do Smartlead lead categories show up in Close?
    Yes. Category updates are logged as activity on the Close Lead alongside sends and replies, so you can see and filter on how each reply was classified.
  • Is the integration one-way or two-way?
    One-way. Activity flows from Smartlead into Close, and nothing is written back to Smartlead.
  • Can I use Close records as a block list?
    Not today. Block lists come from HubSpot lists or Salesforce reports. The Close beta syncs activity in only.
  • Do I need admin access to set it up?
    A Close admin authorizes OutboundSync from the Close App Marketplace during guided onboarding.
  • Which Smartlead plan do I need?
    OutboundSync requires Smartlead's Pro plan or higher, because it relies on Smartlead's webhook and API features.
  • How is Smartlead + Close priced?
    Beta access is scoped with the OutboundSync team during onboarding. Billing follows the same model as every plan: sent messages per month. Replies, opens, clicks, and lead-category updates are not billed. See the pricing page.
  • Can I do this with Zapier, Make, or n8n?
    For lightweight Smartlead automations, yes. When you need dependable attribution and suppression, generic builders get expensive and brittle at volume. OutboundSync is pre-built, keeps searchable event logs beyond 30 days, and prices by outbound volume instead of step count.
  • What breaks first when this scales?
    Data quality and reliability break first: duplicate events, retries, out-of-order webhooks, and bursts during big sends. OutboundSync handles idempotency, timing buffers, and queue recovery, and flags suspicious or mismapped payloads instead of writing them.
