Resend integration
Send quotes, invoices, receipts and dunning notices from Bunny through your own Resend account, on your own domain — with a test recipient so you can verify before customers see anything.
What the integration does
Your domain, your reputation
Billing mail is sent from your company domain rather than a shared platform sender.
Everything transactional
Quote notifications, invoices, receipts, dunning notices and portal invitations route through Resend.
Test recipient built in
Set a test recipient address to route mail to while you are validating templates and configuration, before any of it reaches a customer.
Minimal configuration
An API key, a sender address and optionally a test recipient — that is the whole plugin.
Transactional email is infrastructure, and like most infrastructure it is only noticed when it fails — an invoice in a spam folder, a portal invitation that never arrives, a dunning sequence that quietly does not go out.
The Resend integration puts Bunny’s billing mail on your own domain and authentication, so it behaves like the rest of your outbound email rather than like mail from a vendor your customer has never heard of.
Validate before you go live
The test recipient setting is worth using. Point it at your own address, run a quote and an invoice through the system, and confirm the sender identity, formatting and links are what you expect before a single customer sees one.

Keep the stack you have
Bunny sits between your CRM, your tax engine, your payment processor and your ledger — so quoting, subscriptions, usage and invoicing share one system of record without anyone migrating off the tools they already use.
