Lemlist + Close integration
Lemlist starts the conversation and Close is where reps finish it. OutboundSync logs every Lemlist email and social step as activity on the Close Lead.

Lemlist + Close at a glance
Lemlist works with Close through OutboundSync. Lemlist email sends, opens, clicks, replies, bounces, and unsubscribes, plus connection requests, social messages, and replies, are logged as activity on the matching Close Lead. Lead categories such as Interested come through too. The OutboundSync team runs onboarding for the Close connection.

|---|---|
| Channels | Email and social |
| Direction | One-way, Lemlist → Close |
| Close records | Leads |
| Block lists | Not available for this pairing |
| Lemlist plan | Needs webhook access |
| Setup | Guided: the OutboundSync team runs onboarding |
Close teams live in Smart Views and the call queue, and Lemlist activity belongs in the same place. With OutboundSync, each Lemlist email and social step lands on the Lead, so a rep opening a record before dialing sees the opens, the accepted request, and the last message without switching tabs.
Category changes matter most here. When Lemlist marks a lead Interested or Not Interested, from either channel, that update is logged on the Close Lead. Build a Smart View on recent Interested activity and reps get a daily call list without building one by hand.

OutboundSync matches or creates Close Leads. Lemlist events land as activity on the Close Lead. See the Close beta guide for details.Can Close send suppression lists back to Lemlist?

One-way. Activity flows from Lemlist into Close, and nothing is written back to Lemlist.Can I use Close records as a block list?

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?
Yes, for lightweight automation. Zapier, Make, and n8n are good for prototypes and simple routing, but they need ongoing maintenance and bill by task or step. OutboundSync is pre-built for outbound CRM sync, keeps searchable event logs beyond 30 days, and prices by outbound volume.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.
