Send supported customer invitations and card-install links using your own Resend account and verified domain. Manage the connection inside **Perkstar → Integrations → Resend**. This is a business integration; white-label ownership is not required. Prepare your domain, connect, test delivery and choose when to activate. Check what was accepted, delivered, held or bounced, and recover without duplicating invitations. ## Choose a sending account | | Perkstar's shared service | Your connected Resend account | | ------------------------------------------------ | ----------------------------------- | -------------------------------------------------------------------------- | | Sending account and domain | Perkstar's | Yours | | Emailable address checks | Applied to supported shared sending | Not used; no Perkstar verification credits spent | | Shared quality exclusions and bounce-rate pauses | Apply | Do not apply | | Shared invitation allowance | Applies | Does not apply; your provider quotas and other feature entitlements remain | | Consent, unsubscribe and duplicate protection | Retained | Retained | | Provider fees and restrictions | Perkstar's service rules | Your Resend contract and quotas | | Connection failure | Reported or held | Held or failed; never silently sent through Perkstar | ## What uses this connection Initial invitations, invitation follow-ups and supported customer card-install emails, including install links for imported customers. Importing a customer record alone does not send an email or prove permission to contact that person. Perkstar sign-in, security and billing emails remain separate. Connecting Resend does not enable the retired manual marketing email composer, send SMS, or configure Klaviyo flows. ## Before you start You need the business owner's own Perkstar login, email-feature access, a Resend account and a verified sending domain. A staff login or Perkstar support preview cannot connect it on your behalf. A closed or suspended account remains blocked. Resend can independently reject, suppress or limit mail from your account. Read the [email sending and connection terms](https://dashboard.perkstar.co.uk/email-provider-terms). Activation is an explicit choice after a signed delivery test. It does not restart a stopped campaign or resend previously accepted invitations.
