Why teams connect Lusha and Resend

Flow Lusha data into Resend in real time — no exports, no schedulers, no custom scripts.

Lusha is a read-only source: Stacksync reads its data in real time and delivers it into Resend, so Resend always reflects the current state of Lusha — without exports, scripts, or schedulers.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Person Profiles, Company Profiles, Email Addresses, Phone Numbers in Lusha with Email events, API keys, Emails, Contacts in Resend in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • Append firmographic company data to account records before territory or scoring runs.
  • Build prospecting lists from Lusha search results and sync them into the CRM as leads.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

What you can sync between Lusha and Resend

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Lusha objects Resend objects
Company Profiles Firmographic records (industry, size, location) appended to account or company rows. API keys Scoped credentials managed per environment for send and read access.
Email Addresses Work emails written into CRM contact fields during enrichment. Emails Sent messages retrievable by ID with current delivery status.
Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls. Broadcasts One-to-many campaign sends addressed to an audience.
Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup. Domains Verified sending domains with DNS and DKIM status.
