    Deliver through Resend

WORKFLOW ACTIONS

Automate Resend sending

Separate actions for content email and Resend Templates, with CC, BCC, Reply-To, tags, topics, and attachments.

TIMELINE EVENTS

Follow outcomes in HubSpot

Review subject, sender, recipient, event type, tags, and template information in the contact timeline.

RELIABLE AT SCALE

Ready for large enrollments

When many contacts enroll at once, sends are processed in order and interrupted work is retried automatically.

HubSpot transactional email with Resend

Bring an external email provider
into HubSpot Workflow.

Email Event Sync keeps HubSpot as your workflow and customer context while using Resend as the external email delivery provider.

Can I send email through Resend from a HubSpot Workflow?

Yes. Use one action for HTML or plain-text email and another for Resend Templates. Map enrolled contact properties into recipients, content, and template variables.

Can I use it for transactional email from HubSpot?

It is designed for notifications, confirmations, account updates, and other operational or transactional messages. Marketing use must still comply with consent, unsubscribe obligations, applicable law, and platform policies.

Can this reduce HubSpot marketing contact costs?

The app does not convert contacts into marketing contacts and bills by usage. Depending on your use case and volume, that can change the cost structure, but it is not a way to bypass Marketing Hub features or consent requirements.

Can Resend email events be written back to HubSpot?

Yes. The app receives sent, delivered, opened, clicked, bounced, and related events, then records them on the matching contact timeline. Optional email activity logging is also available.

Simple, usage-based pricing

Contact cost context

Keep the email history
without increasing marketing contacts.

Email Event Sync does not change a HubSpot contact into a marketing contact. It sends through Resend and records activity in the timeline, separating email visibility from the cost of a HubSpot marketing audience.

HUBSPOT MARKETING CONTACTS

Additional-contact cost depends on your plan

In HubSpot's published pricing, the 1,001-3,000 Marketing Hub Starter contact band is $50 per month.

EMAIL EVENT SYNC

Usage is based on processing, not contact count

The $19 monthly plan includes 1,000 credits. Adding a contact alone does not increase this app's usage.

This app is not a replacement for Marketing Hub. Actual pricing varies by plan, region, currency, discount, and contact band. Comparison basis: September 5, 2026. See HubSpot marketing contacts pricing.

App-specific data processing notice

Data Processing Notice
for Email Event Sync

This notice supplements our Privacy Policy, Terms of Service, and Cancellation Policy.

Role and purpose

For customer-controlled HubSpot contact data, we act as a processor on the customer's instructions to send email, record events, handle incidents, and bill usage. We do not synchronize contacts with Resend.

Data processed

We process OAuth credentials, HubSpot portal ID, contact ID, email address, senders and recipients, body, headers, attachment references, Resend email ID, events, and billable usage. OAuth tokens and PKCE verifiers are encrypted with Cloud KMS.

Service providers

We use Cloudflare, Google Cloud, Resend, Hookdeck, Stripe, and Slack. Slack receives operational identifiers only, never email bodies, addresses, tokens, or webhook payloads.

Retention and deletion

R2 payloads containing email body, recipients, and attachment references expire after 30 days. On cancellation or detected disconnect, we delete tenant configuration, Queue, webhook, and service data.

Security

Signature verification, least privilege, OAuth authorization, KMS encryption, tenant-specific Queues, short retention, and privacy deletion constrain the processing scope.

Customer cooperation

Customers receive data-subject requests as the controller. On a privacy deletion event, we delete in-app state and short-retention payloads associated with that contact.
