Instantly is a powerful email outreach platform built for agencies and sales teams who need to manage multiple campaigns, domains, and client accounts from a single dashboard. The OutboundSync integration brings every Instantly campaign interaction directly into HubSpot or Salesforce, transforming your CRM into a complete view of all outbound activity.
Each email send, open, click, and reply is logged as a timestamped activity on the contact record, with intelligent contact matching that prevents duplicates while creating new records for net-new prospects. Instantly's unique campaign structure—where sequences can be paused, resumed, or modified mid-flight—is fully reflected in your CRM activity timeline, giving sales reps and managers complete visibility into prospect engagement without switching between tools.
The integration also syncs Instantly's powerful deliverability metrics, including spam folder placement and domain health signals, so RevOps teams can monitor sender reputation alongside campaign performance.
For agencies managing multiple client workspaces, OutboundSync ensures that each client's CRM stays updated with only their relevant campaign data, maintaining clean data boundaries across accounts.
Instantly has native HubSpot and Salesforce connectors, but the Salesforce one only enrolls contacts into Instantly, HubSpot activity is one-way, and Instantly itself points to a partner like OutboundSync for real two-way CRM data.
| CRM | Native connector | With OutboundSync |
|---|---|---|
| HubSpot | Activity sync is one-way. Instantly recommends a partner like OutboundSync or webhooks when you need full two-way data written to CRM objects. | Logs every send, reply, open, click, and unsubscribe as structured HubSpot timeline activity, syncs block lists both ways, and attributes revenue to campaigns. |
| Salesforce | It only pulls contacts into Instantly — it does not write sends, replies, or activity back into Salesforce. | Writes outbound activity into Salesforce and drives automation through field updates, with block-list sync and campaign attribution built in. |
