Why teams connect Front and Resend

Stop re-entering the same information in Front and Resend: Stacksync keeps the records they share consistent in real time, in both directions.

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 Inboxes, Tags, Teammates, Channels in Front with Domains, Email events, API keys, Emails 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

  • Feed CSAT and SLA reporting from synced conversation events rather than manual exports.
  • Sync conversations, messages, and tags into Postgres for response-time and volume analytics across inboxes.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.

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.

Where Resend is where the team documents or plans: keep its data fed

Information that originates in Front stays current in Resend instead of going stale after a one-time paste.

Handoffs between teams

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

What you can sync between Front 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.

Front objects Resend objects
Channels Connected addresses (email, SMS, chat); define where messages originate and send from. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Conversations The central threaded unit that messages, comments, and tags attach to; synced for support analytics. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Messages Inbound and outbound emails, chats, and SMS within a conversation; read out for response-time reporting. Broadcasts One-to-many campaign sends addressed to an audience.
Comments Internal team notes on conversations; usually read-only in syncs. Domains Verified sending domains with DNS and DKIM status.
Contacts People across channels; matched to CRM contacts, with custom fields carrying external context. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Accounts Company groupings of contacts; kept aligned with CRM accounts. API keys Scoped credentials managed per environment for send and read access.
