Smartlead + HighLevel integration

Agencies run Smartlead for volume and HighLevel for each client's CRM. OutboundSync writes Smartlead activity as Notes on the matching Contact in the authorized sub-account.

Smartlead + HighLevel at a glance

Smartlead connects to HighLevel through OutboundSync. Smartlead sends, opens, clicks, replies, bounces, unsubscribes, and lead category changes are written as plain-text Notes on the matching HighLevel Contact inside one authorized sub-account. OutboundSync matches on email, creates Contacts when needed, and keeps name, phone, and company current on each match.

Smartlead's multi-mailbox setup is a natural fit for agencies, and so is HighLevel's sub-account model. OutboundSync connects them per Location, so a client's HighLevel only ever receives activity from the Smartlead source you wired to it. Client teams stop asking for campaign exports because the history is already on their Contacts.

Every Note is plain text, which keeps it readable in HighLevel's Contact view and easy to scan on mobile. The lead category from Smartlead rides along, so the client sees how Smartlead categorized each reply.

What teams do with Smartlead + HighLevel

  • Hand clients warm leads

    Client teams filter HighLevel Contacts with interested Smartlead replies and call them the same day.

  • Prove campaign activity

    Each Smartlead touch sits on the Contact, which beats a monthly report when a client asks what happened.

  • Keep Contacts clean

    Email stays the dedup key and is never overwritten, so Smartlead activity doesn't fork duplicate Contacts.

Smartlead + HighLevel FAQ

  • What Smartlead activity does OutboundSync sync to HighLevel?
    Email sent, email opened, link clicked, reply received, email bounced, lead unsubscribed, and lead category updated.
  • Which HighLevel records does it write to?
    OutboundSync matches or creates HighLevel Contacts. Smartlead events land as plain-text Note on the Contact. See the HighLevel beta guide for details.
  • Which HighLevel records does Smartlead activity touch?
    Only Contacts and Notes. Opportunities, pipelines, tasks, and tags are left alone, so your client workflows keep running on the data they already use.
  • Is the integration one-way or two-way?
    One-way. Activity flows from Smartlead into HighLevel, and nothing is written back to Smartlead.
  • Can I use HighLevel records as a block list?
    Not today. Block lists come from HubSpot lists or Salesforce reports. The HighLevel beta syncs activity in only.
  • Do I need admin access to set it up?
    The HighLevel user who authorizes the Location must use the same email as their OutboundSync login.
  • 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 + HighLevel 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.
